01 Critical Distinction

Warranty vs. Representation — Why the Difference Matters Enormously

Typical Contract Language
“Each party represents and warrants that: (i) it has the full right, power, and authority to enter into and perform this Agreement; (ii) this Agreement has been duly authorized, executed, and delivered; and (iii) this Agreement constitutes the legal, valid, and binding obligation of such party, enforceable in accordance with its terms.”

Most commercial contracts say “represents and warrants” without distinguishing the two — but when something goes wrong, the distinction can determine whether you can void the entire contract or are limited to damages only.

Representations: Statements of Present Fact

A representation is a statement of past or present fact made to induce another party to enter a contract. “I own the intellectual property underlying these deliverables” is a representation — it asserts that something is currently true. The legal test focuses on what was true at the moment the statement was made and on the mental state of the party making it (did they know it was false?).

If a representation is false, the aggrieved party has a claim for misrepresentation. The spectrum of culpability determines available remedies:

Innocent misrepresentation — the party genuinely believed it was true. Remedy: rescission and restitution (but not expectation damages).
Negligent misrepresentation — the party lacked reasonable grounds for belief. Remedy: rescission plus actual damages.
Fraudulent misrepresentation — the party knew it was false or acted recklessly. Remedy: rescission, actual damages, and potentially punitive damages.

Warranties: Ongoing Contractual Promises

A warranty is a contractual promise that something is or will remain true, for which the promisor accepts ongoing responsibility. Warranty breach does not require showing the promisor knew the statement was false — it is strict liability. If the warranty is untrue, the promisor is liable regardless of intent or knowledge.

If a warranty is breached, the primary remedy is damages — not automatic rescission. The injured party receives compensation to put them where they would have been had the warranty been true. Rescission is available for warranty breach only when the breach is so material that it destroys the essence of the bargain.

Key Principle

The practical shortcut: Read every “represents and warrants” clause twice. First ask: is this a statement of present fact (representation) or an ongoing promise (warranty)? Then ask: what remedy does the contract provide if it is false? The reliance element required for misrepresentation makes it harder to prove than warranty breach — but misrepresentation offers rescission and (in fraud cases) punitive damages that warranty breach does not.

02 High Importance

Express vs. Implied Warranties — UCC §§ 2-313, 2-314, 2-315, 2-316

Express Warranties (UCC § 2-313)

Express warranties arise from: (1) any affirmation of fact or promise about the goods that becomes part of the basis of the bargain; (2) any description of the goods that becomes part of the basis of the bargain; or (3) any sample or model used in the transaction. The seller does not need to use the word “warranty” or “guarantee.” A salesperson saying “this machine handles 500 units per hour” creates an express warranty even if the written contract says “no warranties except as expressly stated herein.”

Red Flag

Oral assurances made during negotiations can create express warranties that survive contract execution — even when the written agreement contains an integration clause. Courts in some jurisdictions, particularly in consumer and small-business contexts, allow evidence of pre-contract oral statements to establish warranty terms. If a seller tells you something specific about the product or service, ask them to put it in writing. If they won't, that is a red flag about whether it is actually true.

Implied Warranty of Merchantability (UCC § 2-314)

Automatically implied in every sale of goods by a merchant who deals in goods of that kind. The goods must: (1) pass without objection in the trade under the contract description; (2) be of fair average quality; (3) be fit for the ordinary purposes for which such goods are used; (4) run within the agreed variations of kind, quality, and quantity; (5) be adequately contained, packaged, and labeled. This warranty applies even if not mentioned — and is breached when a product fails in its ordinary use.

Implied Warranty of Fitness for Particular Purpose (UCC § 2-315)

Arises when the seller knows: (1) the buyer's particular purpose, and (2) the buyer is relying on the seller's skill or judgment to select suitable goods. Unlike merchantability (which covers ordinary uses), this warranty covers the buyer's specific use. A buyer who tells a parts supplier “I need a pump for a food-grade environment” and relies on the supplier's recommendation gets this warranty — even if the written order never mentions food-grade requirements.

Disclaiming Implied Warranties (UCC § 2-316)

To validly disclaim implied warranties:

Merchantability: Must use the word “merchantability” and the disclaimer must be conspicuous (bold, larger font, different color, or all caps — something that draws a reasonable person's attention).
Fitness for particular purpose: Must be in writing and conspicuous. Need not use the word “fitness.”
As-is clauses: “As is,” “with all faults,” or “in its present condition” — when conspicuous — disclaims all implied warranties.

Watch Out

A disclaimer buried in dense fine print in the same font as surrounding text will not be enforceable as “conspicuous” under the UCC. Courts routinely find disclaimers unenforceable on conspicuousness grounds. If you are the seller relying on a disclaimer, put it in bold, a separate box, or all caps — and have the buyer acknowledge it separately.

03 High Stakes

Remedies — Rescission, Damages, and the Fraud Multiplier

Claim Type	Mental State Required	Primary Remedies	Reliance Required?
Breach of Warranty	None (strict liability)	Benefit-of-bargain damages; rescission only for material breach	No (NY rule per CBS v. Ziff-Davis)
Innocent Misrepresentation	Good-faith belief in truth	Rescission + restitution	Yes
Negligent Misrepresentation	Lacked reasonable basis	Rescission + actual damages	Yes
Fraudulent Misrepresentation	Knew false or reckless disregard	Rescission, actual damages, punitive damages	Yes

Damages Calculation for Warranty Breach

Under UCC § 2-714, warranty breach damages equal the difference between the value of the goods as warranted and their actual value at the time of acceptance, plus incidental and consequential damages. Example: you purchased a CNC machine warranted to produce 200 parts/hour for $180,000. Its actual capacity is 80 parts/hour, giving it a value of $72,000. Direct damages = $108,000. If you had to rent substitute capacity during the downtime at $15,000, that is recoverable incidental damage. If you lost a downstream contract worth $50,000 that the seller knew about at contracting, that is a recoverable consequential damage (subject to any limitation of liability cap).

What to Do

If you are the buyer and the seller is disclaiming all consequential damages, disclose your most critical downstream exposures in the contract itself before the limitation of liability clause takes effect. Courts in some jurisdictions carve out foreseeable consequential damages when the seller had specific knowledge of the buyer's critical dependency at contracting.

04 Negotiation Leverage Point

Knowledge Qualifiers & Materiality Scrapers

The Three Levels of Knowledge

Knowledge qualifiers limit a warranty or representation to what the warrantor actually knows. Courts recognize three standards:

“To Seller's actual knowledge” — only conscious awareness by specified individuals (typically named executives). The seller bears no duty to investigate.
“To Seller's knowledge” — actual knowledge plus facts a reasonable inquiry would have revealed. Implies a duty of investigation. This is the ABA model standard.
“To Seller's best knowledge” — typically the broadest: actual knowledge plus constructive knowledge after diligent inquiry. Sellers resist this language.

Watch Out

When a warranty is qualified by “to Seller's knowledge,” always negotiate to define whose knowledge counts. If “knowledge” means only the CEO, the company's general counsel might have known about pending litigation and that knowledge is excluded. Push for: “knowledge means the actual knowledge of [named officers], plus facts that any of them would have known upon reasonable investigation of the applicable subject matter.”

Materiality Qualifiers and Their Impact

Many representations are qualified by “material” — “Seller has no material litigation pending.” This qualifier shifts the risk of immaterial breaches to the buyer. In M&A deals, “Material Adverse Effect” (MAE) is a defined term used in dozens of representations; its precise definition can determine whether a deal can be walked away from after signing.

Materiality Scrapers — What They Do

A materiality scraper removes all materiality and knowledge qualifiers from the warranty text when calculating indemnification obligations. The warranty still uses the qualifier (so the breach threshold stays the same), but the indemnification calculation ignores it (so small losses are still recoverable). Without a scraper, the buyer must prove both that a breach occurred and that the breach was “material” to recover indemnification. With a scraper, once any breach is shown, all resulting losses are recoverable regardless of size.

What to Do

If you are the buyer in an M&A deal, fight for materiality scrapers in the indemnification section. If you are the seller, resist scrapers or negotiate for a minimum loss threshold (deductible or basket) that prevents recovery for trivial breaches even after the scraper removes the materiality filter.

05 M&A Deal-Breaker Issue

Sandbagging & Anti-Sandbagging Clauses — Jurisdiction Split

Sandbagging occurs when a buyer discovers a warranty breach during due diligence, closes the deal anyway, and then brings a warranty claim post-closing. The seller argues: “You knew — you can't now claim damages.” The buyer argues: “A warranty is a contractual promise; reliance is not an element of warranty breach.”

Clause Type	Effect	Who Prefers It	Key Case
Pro-sandbagging	Buyer may claim warranty breach regardless of pre-closing knowledge	Buyer	Rogath v. Siebenmann (2d Cir. 1997)
Anti-sandbagging	Buyer waives claims for breaches known before closing	Seller	Galli v. Metz (9th Cir. 1992)
Silent (NY law)	Pro-sandbagging by default — knowledge does not bar claim	Buyer	CBS v. Ziff-Davis (N.Y. 1990)
Silent (CA law)	Anti-sandbagging by default — actual knowledge may bar claim	Seller	Galli v. Metz (9th Cir. 1992)

Red Flag

If your M&A agreement is silent on sandbagging and governed by California law, you may be barred from asserting a warranty breach claim you discovered during due diligence — even if you have a written warranty. Always negotiate an express pro-sandbagging clause or, if you are the seller, an anti-sandbagging clause. Do not leave this to jurisdictional default rules.

06 Time-Critical

Survival Clauses & Limitation Periods — Calendar These Deadlines

A survival clause specifies how long representations and warranties remain actionable after the agreement closes or is executed. Without a survival clause, the general contract statute of limitations applies (4–6 years in most states for written contracts). Survival clauses almost always shorten this period significantly.

Context	Typical General R&W Survival	Fundamental Reps	Fraud
M&A (Private)	12–24 months post-close	Indefinite or statute of limitations	Indefinite
SaaS / Services	Subscription term only	N/A	State SOL
Construction	1 year from substantial completion	State implied warranty (1–10 yrs)	State SOL
Real Estate (Sale)	Often none after closing (as-is)	Varies by state	State SOL
UCC Goods (default)	4 years from breach (§ 2-725)	Same	State SOL

Key case: Anchor Savings Bank v. Eagleston (WA Ct. App. 1988) held that a contractual survival clause that shortened the warranty period to 12 months after closing was enforceable as a contractual modification of the statute of limitations under UCC § 2-725(1), even when the underlying defect was not discoverable within that period. The discovery rule does not automatically extend contractual survival periods.

Red Flag

If you are the buyer and you discover a possible warranty breach at month 11 of a 12-month survival period — even if you are not certain — you must provide written warranty claim notice before the survival deadline expires. Most contracts require notice within the survival period as a condition of bringing a claim. Missing this deadline by a single day is typically fatal to the claim, regardless of how strong the underlying breach is.

What to Do

Calendar every warranty survival deadline the day you sign. Set a reminder 60 days before expiration to conduct a final review of performance, representations, and any developing issues. Provide written protective notice of potential claims before the deadline if there is any doubt — most contracts permit notice of claims even before damages are fully quantified.

07 Case Law

6 Landmark Cases Every Party Should Know

CBS Inc. v. Ziff-Davis Publishing Co.

New York Court of Appeals1990

Holding: A buyer who closes despite knowing of a possible warranty breach can still sue for warranty breach — reliance in the sense of "believing the statement is true" is not required. The buyer relies on the warranty as a bargained-for contractual promise.

Impact: Established the pro-sandbagging default in New York. Defines warranty reliance as reliance on the contractual promise, not subjective belief in its truth. Foundational authority for why warranties are strict-liability obligations rather than fraud-adjacent claims.

Hendricks v. Callahan

8th Circuit Court of Appeals1993

Holding: Distinguished warranty claims (strict liability, damages remedy) from misrepresentation claims (scienter or negligence required, rescission available). A false statement about a business's revenues made in a purchase agreement was both a warranty and a representation — the remedies available depended on which theory the plaintiff invoked.

Impact: Reinforced that the "represents and warrants" formulation creates two distinct legal claims with different proof requirements and remedies. Demonstrates the importance of pleading both theories when a statement is false.

Rogath v. Siebenmann

2nd Circuit Court of Appeals (N.Y. law)1997

Holding: In a painting sale, the buyer knew before closing that the seller's warranty of authenticity was disputed. The court upheld the buyer's right to sue for warranty breach post-closing — a warranty is enforceable despite the buyer's knowledge of potential breach, unless the seller can show the buyer knew the warranty was actually false.

Impact: Refined the CBS v. Ziff-Davis rule: buyer's knowledge of uncertainty or dispute does not bar a warranty claim; only actual knowledge that the warranty is definitely false may do so. Supports aggressive buyer positions in M&A sandbagging disputes.

Galli v. Metz

9th Circuit Court of Appeals (CA law)1992

Holding: Under California law, a buyer who knew of a warranty breach before closing generally cannot recover for that breach post-closing. California's reliance-based approach to warranty claims means actual pre-closing knowledge defeats the claim — even without an explicit anti-sandbagging clause.

Impact: Established the anti-sandbagging default in California. Directly conflicts with the New York rule. Governing law selection in M&A agreements is therefore outcome-determinative on sandbagging. Any M&A agreement without express sandbagging language governed by California law favors the seller.

Anchor Savings Bank, FSB v. Eagleston

Washington Court of Appeals1988

Holding: A contractual warranty survival clause shortening the claim period to 12 months post-closing was enforceable under UCC § 2-725(1) as a valid modification of the default four-year limitations period. The fact that the defect was latent and not discoverable within the survival period did not toll the contractual deadline.

Impact: Confirms that contractual survival clauses are enforceable to shorten limitations periods, even against latent defects. Sellers can rely on survival clause deadlines as hard cutoffs. Buyers must calendar survival deadlines carefully and provide timely notice of potential claims even before damages are quantified.

Ziff-Davis Publishing Co. v. Mohr

New York Supreme Court (Commercial Division)2001

Holding: An express warranty of accurate financial statements in a stock purchase agreement was breached when undisclosed liabilities emerged post-closing. The court awarded benefit-of-the-bargain damages equal to the overpayment, rejecting the seller's argument that the contract's integration clause barred reliance on warranted financial figures.

Impact: Illustrates that express warranty claims in M&A agreements are not defeated by integration clauses — the warranty itself is part of the written agreement. Financial statement warranties are among the most litigated and most expensive to breach; companies should conduct independent financial due diligence regardless of warranted financials.

Industry-Specific Warranties — M&A, SaaS, Real Estate, Construction

M&A — Representations & Warranties

Private M&A agreements include comprehensive R&W sections covering: organization and authority; capitalization (no undisclosed equity); financial statements (GAAP-compliant, no material misstatements); absence of changes (MAC/MAE); material contracts (no undisclosed obligations); IP (ownership, non-infringement, no open-source contamination); litigation; environmental; employee matters; taxes. Backed by indemnification obligations (deductible basket + cap) and increasingly by R&W insurance. Survival periods: 12–24 months for general reps, indefinite for fundamental reps and fraud.

Key negotiation point: The indemnification basket (deductible) and cap set the effective economic protection. A $5M acquisition with a 1% basket ($50K) and 10% cap ($500K) means the seller effectively guarantees only the first $500K of warranty losses above $50K.

SaaS & Software Services

Typical SaaS warranties: (1) services will perform materially in accordance with documentation; (2) no introduction of malware or unauthorized code; (3) vendor has rights to grant the license (IP non-infringement); (4) services will comply with applicable data protection laws. Sole remedy is usually reperformance or pro-rated refund. Implied warranties are disclaimed explicitly. Watch for: IP non-infringement warranties with carve-outs for open-source components (may inadvertently gut the warranty); performance warranties qualified by “material” (leaves room for significant degradation before breach).

Real Estate

Commercial real estate sales: as-is clauses are broadly enforced; implied warranties are largely disclaimed; buyers must rely on due diligence. Residential sales: most states impose mandatory disclosure obligations for known material defects that cannot be contractually waived. New construction: implied warranty of workmanlike construction and habitability exists in most states; duration varies (1–10 years depending on defect type). Deed warranties: a general warranty deed carries the seller's covenant of title and quiet enjoyment; a special warranty deed limits the warranty to defects arising during the seller's ownership; a quitclaim deed gives no warranty of title whatsoever.

Construction Contracts

Standard AIA contract forms include a one-year warranty period for correction of work (§ 3.5 of AIA A201), but this does not cap the contractor's liability for latent defects discovered after the one-year period — it is a correction obligation, not a limitation on claims. Implied warranty of workmanlike construction survives independently. Key issues: (1) whether the warranty runs to subsequent owners (minority of states); (2) whether design errors by the architect are carved out from the contractor's warranty (they usually are); (3) whether the warranty covers third-party supplier defects (depends on whether the contractor passed through the supplier's warranty). Construction warranties are among the most litigated — always obtain the contractor's insurance certificates and confirm the policy covers warranty claims.

Negotiation Matrix — 8 Clause Scenarios

Clause Language	Risk Level	Your Leverage	Counter-Offer	Walk-Away Signal
"Seller warrants compliance with all applicable laws"	🔴 High	Regulatory changes after signing could instantly create breach	Add: "as in effect as of the Effective Date and to Seller's knowledge as of the date hereof"	Seller refuses any knowledge qualifier or date limitation
"ALL IMPLIED WARRANTIES DISCLAIMED; SERVICES PROVIDED AS-IS"	🟡 Medium	Implied warranty of fitness eliminated; cure may be your only remedy	Carve out: IP non-infringement and data security from the disclaimer	Disclaimer also eliminates IP ownership warranty with no substitute
"Warranties survive for 12 months post-closing"	🟡 Medium	Short window; calendar immediately upon signing	Push for 18–24 months for general reps; indefinite for fundamental reps and fraud	Survival period is less than 6 months for anything other than pure SaaS
"Sole remedy for warranty breach is reperformance"	🟡 Medium (SaaS) / 🔴 High (M&A)	Eliminates damages remedy; reperformance may be inadequate for critical systems	Add: "or refund of fees paid for the defective period, at Buyer's election" as alternative sole remedy	Sole remedy applies to IP infringement claims — leaves you exposed to third-party infringement suits
"To Seller's actual knowledge, no pending litigation"	🟡 Medium	"Actual knowledge" of named individuals only; company-level knowledge excluded	Expand to: "knowledge of [CEO, CFO, GC] plus facts that would be discovered upon reasonable inquiry of HR and legal records"	Seller refuses to name any individuals or add any due inquiry requirement
"Buyer waives all claims for breaches known to Buyer at Closing"	🔴 High	Anti-sandbagging — eliminates warranty claims for all due diligence findings	Counter: "Buyer does not waive claims unless Seller has disclosed the breach in a written Disclosure Schedule prior to signing"	Clause is combined with a broad definition of "known" including constructive knowledge
"Warrantor's liability for warranty claims is capped at the Purchase Price"	🟢 Reasonable	Full-price cap is standard in M&A; key is what is excluded from the cap	Exclude from cap: fraud, willful misconduct, IP indemnification, confidentiality breaches, and fundamental rep breaches	Cap applies to fraud and intentional misrepresentation — no cap carve-outs whatsoever
"No warranty regarding third-party software or open-source components"	🟡 Medium	Common in SaaS; may gut IP non-infringement warranty if product is heavily open-source	Request: list of all open-source components used; confirm licenses are permissive (MIT, Apache) not copyleft (GPL)	Vendor refuses to disclose open-source components or confirm license types

11 Avoid These

8 Common Warranty Mistakes with Dollar Costs

Giving broad IP non-infringement warranties without an IP audit

$50K–$2M+

If a competitor sues your client for IP infringement on software you warranted, you are on the hook for defense costs, settlement, and royalties. IP audits cost $5K–$20K. Warranty exposure without one can be unlimited.

Warranting compliance with all laws without a "as of date" limitation

$10K–$500K

Regulatory changes — GDPR amendments, CCPA updates, sector-specific regulations — can make a currently true warranty false overnight. Limit compliance warranties to "laws in effect as of the Effective Date" or "to Seller's knowledge as of closing."

Failing to disclaim implied UCC warranties as a seller of goods

$5K–$200K

The implied warranty of merchantability attaches automatically to every merchant sale. A product that fails in ordinary use creates an automatic breach claim — for the full purchase price plus consequential damages — without any written warranty language.

Accepting unlimited warranty liability with no cap

Contract value or more

Without a liability cap, a single warranty claim can exceed your entire contract value. In a $500K services contract where your error causes the client $2M in downstream losses, an uncapped warranty exposes you to the full $2M.

Missing the warranty survival deadline without noticing a potential breach

100% of claim value

Missing a survival period deadline by one day is fatal — regardless of how strong the underlying breach is. In a 12-month survival deal, a defect emerging at month 13 produces a $0 recovery even if the warranty was clearly false at closing.

Signing an as-is clause after receiving oral assurances about condition

Entire purchase price

In most jurisdictions, an as-is clause overrides prior oral statements about condition (except fraud). If a seller says "the roof is fine" orally and you sign a contract with an as-is clause, you own the roof problem — and the cost of repair.

Failing to define "material" in material adverse effect representations

$100K–$5M

An undefined MAE gives the other party room to argue that minor fluctuations, regulatory inquiries, or customer dissatisfaction constitute MAEs. In a deal walk, the difference between a defined and undefined MAE can be the entire transaction.

Accepting knowledge-qualified warranties without specifying whose knowledge counts

$50K–$1M

If "knowledge" is not defined, courts may limit it to the signing officer alone. A company's general counsel might know about pending litigation; if the GC's knowledge doesn't count, the company avoids liability for a breach that was internally known.

Frequently Asked Questions

What is the legal difference between a warranty and a representation?

A representation is a statement of present or past fact made to induce a party to enter a contract. If false, the remedy is rescission and/or misrepresentation damages. A warranty is a contractual promise that something is or will be true, for which the promisor accepts ongoing liability. If breached, the remedy is breach-of-warranty damages. The critical practical difference: a false representation can void the entire contract via rescission; a breached warranty typically supports only damages. Most commercial contracts say "represents and warrants" without distinguishing the two, which courts treat as creating both obligations.

What are the UCC implied warranties and how do I disclaim them?

UCC Article 2 implies three warranties into every sale of goods: (1) The implied warranty of merchantability (§ 2-314) — goods must pass without objection in the trade and be fit for the ordinary purposes for which they are used. (2) The implied warranty of fitness for a particular purpose (§ 2-315) — applies when a seller knows the buyer's specific purpose and the buyer relies on the seller's skill to select suitable goods. (3) The warranty of title (§ 2-312) — the seller warrants that title is good, transfer is rightful, and no undisclosed liens exist. To disclaim merchantability: use the word "merchantability" in writing, and it must be conspicuous (larger font, different color, or capital letters). To disclaim fitness: must be in writing and conspicuous. An "as-is" or "with all faults" clause in the contract disclaims both implied warranties if conspicuous.

What is a knowledge qualifier and should I accept "to Seller's knowledge" language?

A knowledge qualifier limits a warranty or representation to what the warrantor actually knows. "Seller represents and warrants, to its knowledge, that no material litigation is pending" means Seller is only liable if they knew about the litigation — not if it existed but was unknown to them. Courts distinguish actual knowledge, constructive knowledge (should have known), and "best knowledge" (actual knowledge after due inquiry). From the buyer's perspective, unqualified warranties are always preferable. If the seller insists on knowledge qualifiers, push to define "knowledge" expansively: actual knowledge of named officers plus facts that would be discoverable through reasonable investigation. The seller's risk argument — I can't warrant what I don't know — is legitimate for some representations but should not apply to core obligations like title, authorization, or regulatory compliance.

What is sandbagging in M&A contracts and is it enforceable?

Sandbagging refers to a buyer who knew of a warranty breach before closing but still closes and later brings a warranty claim. A "pro-sandbagging" clause preserves the buyer's right to claim warranty breach regardless of pre-closing knowledge. An "anti-sandbagging" clause bars claims for breaches the buyer knew about before closing. New York courts (Rogath v. Siebenmann, 2d Cir. 1997) enforce pro-sandbagging clauses and hold that a buyer's knowledge does not defeat a warranty claim unless the contract specifically bars it. California courts (Galli v. Metz, 9th Cir. 1992) reach the opposite result — actual knowledge of a warranty breach can bar claims under California law even without an explicit anti-sandbagging clause. Always negotiate for express language; silence on sandbagging creates jurisdiction-dependent uncertainty.

How long do warranties survive after a contract closes?

Survival periods define how long warranties remain actionable after closing or contract execution. Without a survival clause, general contract statutes of limitations apply — typically 4–6 years for written contracts. In M&A deals, typical survival periods are: general representations and warranties 12–24 months; fundamental reps (title, authorization, capitalization) survive indefinitely or for the statutory period; fraud survives indefinitely. In construction contracts, express warranties typically run 1 year from substantial completion, but statutory implied warranty periods may run longer. In SaaS agreements, service warranties typically last only for the subscription term. Always confirm: (1) what specific warranties survive; (2) how long; (3) whether any claims must be noticed before the survival period expires; and (4) whether the survival period shortens the statute of limitations.

What is a materiality scraper and why does it matter?

A materiality scraper (or "material adverse effect scraper") is a clause that removes all materiality and knowledge qualifiers from representations and warranties when calculating indemnification obligations. For example, a rep might say "Seller has no material litigation pending." If breached by any litigation (not just material litigation), the materiality scraper means the indemnification calculation ignores the "material" qualifier — the buyer recovers for all losses, not just losses that exceed a materiality threshold. Sellers hate scrapers; buyers love them. The result without a scraper: a warrantor can breach a "material" qualifier only moderately and avoid indemnification by arguing the breach wasn't material. With a scraper: any breach triggers indemnification calculated without the materiality filter.

What is the CBS v. Ziff-Davis case and why does it matter?

CBS Inc. v. Ziff-Davis Publishing Co. (N.Y. Court of Appeals, 1990) is the leading case on the reliance element in warranty claims. Ziff-Davis warranted that a group of magazines had a specific circulation figure. CBS knew before closing that the actual circulation might be lower but closed anyway. The New York Court of Appeals held that CBS could still sue for warranty breach — the issue is not whether CBS "relied" on the warranty in the sense of believing it, but whether CBS relied on the warranty as a contractual promise. A warranty is a bargained-for assurance; it is breached if untrue regardless of the warrantee's subjective beliefs. This principle supports pro-sandbagging positions and distinguishes warranty claims from misrepresentation claims, where actual reliance is a required element.

How do warranties differ in SaaS versus M&A contracts?

In SaaS agreements, warranties typically include: (1) service will perform materially in accordance with documentation; (2) vendor will not introduce malware; (3) vendor has rights to grant the license; (4) services will not infringe third-party IP. SaaS warranties are usually limited to the subscription term, with sole remedy being reperformance or pro-rated refund. In M&A deals, representations and warranties are comprehensive — covering title, capitalization, financial statements, absence of changes, compliance, IP, material contracts, litigation, taxes, and employees. M&A reps survive closing for defined periods and are backed by indemnification obligations and often R&W insurance. The scope and consequence differences are enormous — a SaaS warranty breach risks losing a few months of subscription fees; a materially false M&A rep can trigger millions in indemnification claims.

What is an "as-is" clause and when is it enforceable?

An "as-is" clause disclaims implied warranties, transferring the risk of defects to the buyer. Under UCC § 2-316(3)(a), language like "as-is," "with all faults," or "in its present condition" disclaims all implied warranties if it is conspicuous. Courts generally enforce as-is clauses between sophisticated commercial parties. However, as-is clauses have limits: (1) they do not disclaim express warranties already made — if the seller said "this equipment runs perfectly" and that is false, the as-is clause doesn't shield the seller; (2) they do not bar fraud claims — a seller who actively conceals defects cannot hide behind an as-is clause; (3) in residential real estate, many states impose mandatory disclosure obligations that override as-is language for known latent defects. If you are the buyer, treat as-is clauses as red flags and negotiate for express warranties on condition, compliance, and title.

What should I negotiate in a warranty clause as a service provider?

As a service provider: (1) Limit performance warranties to "services will perform materially in accordance with the agreed specifications" — avoid warranting fitness for any particular purpose. (2) Make cure the sole remedy for warranty breach — specify that the client must give written notice, you have 30 days to cure, and only if cure fails does the client have a refund or termination right. (3) Disclaim all implied warranties explicitly and conspicuously. (4) Cap your warranty liability at fees paid in the preceding 3–6 months. (5) Exclude from warranty coverage: problems caused by client modifications, client-provided materials, third-party integrations, or use inconsistent with documentation. (6) Set the warranty period at the shorter of: 90 days from delivery, or the subscription term for SaaS. (7) Exclude open-source components from IP non-infringement warranties.

What are the most expensive warranty mistakes businesses make?

The eight most costly mistakes: (1) Giving broad IP non-infringement warranties without an IP audit — potential exposure: full indemnification of client's defense costs plus royalties. (2) Warranting compliance with all laws without qualification — regulatory changes can instantly create breach. (3) Failing to disclaim implied warranties — UCC implied warranty claims can cover the full purchase price. (4) Agreeing to unlimited warranty liability with no cap — a single warranty claim can exceed the entire contract value. (5) Missing the warranty survival deadline without noticing a breach — if you discover a seller's warranty breach at month 13 and the survival period was 12 months, your claim is gone. (6) Signing an as-is clause after receiving express oral assurances — the as-is clause usually wins in court. (7) Failing to define "material" in material adverse change reps — leaves you exposed to every minor issue. (8) Accepting knowledge-qualified warranties without defining whose knowledge counts.

Can a warranty clause reduce the statute of limitations?

Yes. Under UCC § 2-725(1), parties to a sale of goods contract may contractually reduce the statute of limitations to as short as one year (though they cannot extend it beyond four years). Many commercial contracts include a contractual limitations period of one or two years — shorter than the state default. Courts generally enforce these reductions between sophisticated commercial parties. Before signing: (1) Check whether the contract specifies a limitations period for warranty claims. (2) Compare it to the state default SOL (4–6 years for written contracts, 4 years for UCC goods). (3) Understand whether the survival clause and the SOL work together — if the survival period is 18 months but the contractual SOL is 12 months, you must notice your claim within 12 months. (4) If you are the buyer or service recipient, push back on any contractual SOL shorter than 2 years.

What is the warranty of habitability and how does it differ from express warranties in real estate?

The implied warranty of habitability applies to residential rentals and, in some states, new residential construction. It is a statutory or common-law implied warranty that premises will be safe and livable — it cannot be waived by lease or contract. In new home construction, most states recognize an implied warranty of workmanlike construction and habitability for a period set by state law (typically 1–10 years depending on the defect type). Express warranties in real estate sales are statements about specific property conditions — "roof was replaced in 2022," "no known foundation issues." Express warranties in a deed or purchase agreement can be enforced even when the as-is clause in the purchase agreement covers the property generally. In commercial real estate sales, as-is clauses are broadly enforced and implied warranties are largely disclaimed — buyers must rely on their own due diligence.

What does representations and warranties insurance (R&W insurance) cover?

Representations and warranties insurance (also called R&W insurance) is a policy that covers losses arising from breaches of R&W in M&A agreements. Buy-side R&W insurance (most common) pays the buyer directly for covered losses, reducing the buyer's reliance on the seller's indemnification obligations. It typically covers the full scope of R&W breaches except: (1) known breaches — anything the buyer knew at signing is excluded; (2) forward-looking statements — projections and forecasts are typically excluded; (3) certain high-risk reps — environmental, pension underfunding, and criminal matters often require separate coverage or sublimits. Premiums run approximately 3–4% of coverage limits. R&W insurance has shifted M&A deal dynamics significantly — it allows sellers to make cleaner exits (reduced escrow, faster indemnification cap burns) and gives buyers a direct-pay insurer to pursue instead of a seller who may have distributed sale proceeds.
