Promissory Note Guide: What to Check Before You Sign

A promissory note is a written, unconditional promise by one party (the maker or borrower) to pay a specified sum of money to another party (the payee or lender) at a defined time or on demand. Unlike an informal IOU, a promissory note that meets the requirements of UCC Article 3 (§ 3-104) is a negotiable instrument — a category that dramatically affects the note's enforceability and the rights of parties who acquire it. **UCC Article 3 Requirements for Negotiability.** To qualify as a negotiable instrument under UCC § 3-104, a promissory note must be: (1) in writing and signed by the maker; (2) an unconditional promise to pay; (3) a fixed amount of money; (4) payable on demand or at a definite time; (5) payable to order or to bearer. A note that does not meet all five requirements is still enforceable as a contract, but it does not benefit from the holder-in-due-course rules that protect third-party purchasers. **Promissory Note vs. Loan Agreement.** A promissory note is a payment obligation — it states who owes what to whom, at what rate, when. A loan agreement (or credit agreement) is a more comprehensive document that also covers representations and warranties, covenants, events of default, remedies, and governing terms. In commercial lending, parties often execute both: the loan agreement governs the relationship, and the promissory note is the negotiable payment instrument. For simpler transactions (private family loans, small business loans between known parties), a well-drafted promissory note alone may be sufficient. **Enforcement Without the Original Note.** In *Steinhardt Group Inc. v. Citicorp*, 708 A.2d 262 (N.J. App. Div. 1998), the court addressed enforcement of a note where the original was lost. UCC § 3-309 provides a procedure for enforcing a lost, destroyed, or stolen instrument: the party must prove the terms of the note, that it was entitled to enforce before the loss, and that the loss was not the result of a transfer or lawful seizure. Courts have generally allowed enforcement under § 3-309 where the holder adequately proves the original terms. However, some lenders — particularly in residential mortgage contexts — have faced challenges when they could not produce the original note in foreclosure proceedings. **The Unconditional Promise Requirement.** A note that conditions payment on some external event ("I will pay if my business succeeds") is not an unconditional promise and is not a negotiable instrument under UCC Article 3. Courts construe the unconditional promise requirement strictly: in *Adams v. Madison Realty & Development, Inc.*, 853 F.2d 163 (3d Cir. 1988), the court confirmed that a note subject to conditions loses its negotiability. The practical consequence is that conditional payment promises are enforceable as contracts, but the holder cannot benefit from HDC status and the note cannot be freely transferred in commerce.

The interest rate on a promissory note is the most obvious financial term, but it interacts with state usury laws, federal preemption rules, and compounding mechanics in ways that significantly affect the true cost of borrowing — and, when the rate is excessive, may render the note partially or fully unenforceable. **Usury Laws.** Every state limits the interest rate that can be charged on loans through usury statutes. Rates above the legal limit may result in: (1) forfeiture of all interest (the lender collects only principal); (2) forfeiture of the entire amount owed; or (3) criminal penalties in egregious cases. State usury limits vary dramatically — from approximately 6% for some consumer loans in certain states to no limit for commercial loans between sophisticated parties in others. **Federal Preemption for National Banks.** In *Marquette National Bank of Minneapolis v. First of Omaha Service Corp.*, 439 U.S. 299 (1978), the Supreme Court held that under the National Bank Act (12 U.S.C. § 85), a national bank may charge the interest rate permitted in its home state regardless of where the borrower is located. This is why credit card companies charter in Delaware and South Dakota (which have no usury limits) and charge those rates nationally. The principle was extended to state-chartered banks in *Smiley v. Citibank (South Dakota), N.A.*, 517 U.S. 735 (1996). For loans from licensed lenders and banks, state usury limits may be preempted. For private individual-to-individual loans, state usury laws apply directly. **Simple vs. Compound Interest.** Simple interest is calculated only on the principal balance. Compound interest is calculated on the principal plus previously accrued interest, causing the outstanding balance to grow exponentially if not paid. Most promissory notes use simple interest. Watch for clauses that capitalize unpaid interest (add it to the principal balance) — this effectively converts simple interest to compound interest and can rapidly increase the amount owed. **The 360-Day Year.** Many commercial promissory notes calculate interest using a 360-day year convention ("30/360" or "actual/360"). This slightly increases the effective annual rate because 12 months × 30 days = 360 days, but interest is charged on 365 actual days, meaning you pay slightly more than the stated annual rate implies. On large loan balances, this difference is economically significant. **Default Interest Rate.** Most promissory notes include a default interest rate that kicks in when the borrower misses a payment — typically 2-5 percentage points above the regular rate. Courts have generally enforced default rate step-ups when they are commercially reasonable, but rates that are so high as to constitute a penalty rather than a legitimate estimate of damages may be challenged as unenforceable liquidated damages clauses under the common law. **TILA Disclosure for Consumer Loans.** The Truth in Lending Act (15 U.S.C. § 1601 et seq.) requires creditors to disclose the annual percentage rate (APR), finance charges, amount financed, and total payments for consumer credit transactions. A promissory note for a personal loan, home purchase, or consumer installment purchase triggers TILA. Failure to make required disclosures entitles the borrower to rescission within three years for mortgage loans (15 U.S.C. § 1635) and statutory damages for other consumer loans.

Understanding your payment obligations under a promissory note — and what happens when you miss one — requires careful analysis of the amortization schedule, balloon payment obligations, late charge terms, and acceleration rights. **Fully Amortizing vs. Balloon Notes.** A fully amortizing promissory note is structured so that regular principal and interest payments, made on schedule, reduce the balance to zero at maturity. A balloon note requires smaller periodic payments (often interest-only or partially amortizing) with a large lump sum — the "balloon" — due at maturity. Balloon notes are common in commercial real estate loans and seller-financed transactions. The risk: borrowers who cannot refinance or sell the property before maturity must either pay the balloon from cash or face default. **Amortization Example.** A $50,000 note at 8% annual interest, fully amortizing over 5 years: monthly payment = approximately $1,013.82. Over 60 months, total payments = ~$60,829. Of this, ~$50,000 is principal repayment and ~$10,829 is interest. An interest-only note on the same terms would require monthly payments of ~$333.33 for 5 years, with a $50,000 balloon payment due at maturity — lower monthly cash outflow but 100% balloon risk. **Events of Default.** Standard default provisions include: (1) failure to make a scheduled payment; (2) breach of any covenant or representation in the note or related agreements; (3) the borrower's insolvency, bankruptcy filing, or assignment for benefit of creditors; (4) material adverse change in the borrower's financial condition (in commercial notes); and (5) cross-defaults — default under any other debt obligation. Cross-default clauses are particularly dangerous: they mean that defaulting on a credit card can trigger default on your business loan. **Acceleration.** Upon default, most promissory notes include an acceleration clause allowing the holder to declare the entire outstanding balance immediately due and payable, without waiting for the scheduled maturity date. In *Westinghouse Credit Corp. v. Shelton*, 645 F.2d 869 (10th Cir. 1981), the court enforced an acceleration clause and rejected the borrower's argument that the lender must give additional notice beyond what the note specified. Courts generally enforce acceleration clauses according to their terms. **Cure Periods.** Well-negotiated promissory notes include a cure period — typically 5-15 days for payment defaults and 30 days for non-payment defaults — during which the borrower can remedy the default before the lender can accelerate. The absence of a cure period is a significant risk: a single missed payment (including one delayed by bank processing) could trigger immediate acceleration of the full balance.

The distinction between a secured and unsecured promissory note is the difference between collateral-backed debt (where the lender can seize specific assets if you default) and general obligation debt (where the lender's only remedy is a judgment against you personally). **Unsecured Notes.** An unsecured promissory note is a general promise to pay. On default, the lender's remedy is to sue, obtain a judgment, and then attempt to collect that judgment from the borrower's assets — a process that can take years and may yield nothing if the borrower is insolvent. Most personal loans between friends and family, and many small business loans at seed stage, are unsecured. **Secured Notes and UCC Article 9.** A secured promissory note is backed by a security interest in specific collateral. For personal property (equipment, inventory, accounts receivable, intellectual property), security interests are governed by UCC Article 9. To be effective against third parties, the security interest must be: (1) *attached* — the borrower must have rights in the collateral, the lender must give value, and the security agreement must authenticate the collateral; and (2) *perfected* — for most personal property, perfection occurs by filing a UCC-1 Financing Statement with the applicable state filing office. **Priority Rules.** Between competing secured creditors, UCC Article 9 establishes priority based on the order of filing (not the order of attachment). A lender who files a UCC-1 first has priority over a lender who attached first but filed later. This is known as the "first to file or perfect" rule. In *In re Filtercorp, Inc.*, 163 F.3d 570 (9th Cir. 1998), the court applied UCC priority rules in a bankruptcy context, confirming that a properly perfected security interest is effective against the bankruptcy trustee. **Real Property Collateral.** For real estate, security interests are governed by state real property law, not UCC Article 9. The lender obtains a mortgage (in most states) or a deed of trust (in California and others). A deed of trust involves three parties — borrower (trustor), lender (beneficiary), and a trustee who holds legal title — and allows non-judicial foreclosure through a trustee's sale, typically faster than judicial foreclosure. **Blanket Liens.** A "first priority security interest in all assets" — sometimes called a blanket lien — covers all present and after-acquired property. For a business borrower, this means the lender has a claim on everything: bank accounts, receivables, inventory, equipment, IP, and any property acquired in the future. Blanket liens significantly restrict the borrower's ability to use assets as collateral for future financing. In *Spurgeon v. Jamieson Motors*, the court confirmed the enforceability of after-acquired property clauses. **Personal Guaranty vs. Collateral.** A secured note relies on specific collateral; a personal guaranty holds an individual guarantor personally liable for the borrower entity's debt. For small business notes, lenders often require both — collateral that can be seized directly and a personal guaranty allowing them to reach the owner's personal assets if the collateral is insufficient.

The holder-in-due-course (HDC) doctrine is one of the most important — and least-understood — aspects of promissory note law. It allows a purchaser of a promissory note to take the note free of most defenses the borrower could have raised against the original lender. This means that disputes with the original lender (fraud, misrepresentation, failure of consideration) generally cannot be used to avoid paying a third-party HDC. **HDC Requirements (UCC § 3-302).** To qualify as a holder in due course, a person must: (1) be a holder (possess the note endorsed to them or to bearer); (2) have given value; (3) have taken the note in good faith; and (4) have taken the note without notice of any claim to it, any defense or claim in recoupment, or the fact that the instrument is overdue. All four requirements must be met. **Personal Defenses vs. Real Defenses.** The HDC doctrine cuts off *personal defenses* — defenses that could be raised against the original payee — but does not cut off *real defenses* (sometimes called "real" or "absolute" defenses). Real defenses include: infancy (if the maker was a minor), duress or incapacity, illegality that renders the contract void (not merely voidable), fraud in the factum (fraudulent misrepresentation as to the nature of the instrument itself), discharge in bankruptcy, and forgery. Personal defenses — which are cut off against an HDC — include: failure of consideration, breach of contract, fraud in the inducement, misrepresentation, and ordinary contractual defenses. **Practical Example.** You sign a promissory note to a contractor who promises to renovate your building. The contractor takes your note, never performs the renovation, and immediately sells the note to a finance company. The finance company qualifies as an HDC — it gave value (paid for the note), acted in good faith, and had no notice of the contractor's breach. The finance company can enforce your obligation to pay, and your defense (failure of consideration by the contractor) is a personal defense that cannot be raised against the HDC. You are stuck paying the note and pursuing the contractor separately. **The FTC Rule for Consumer Credit Contracts.** Recognizing the harshness of the HDC doctrine in consumer contexts, the Federal Trade Commission adopted 16 C.F.R. § 433 (the "Holder Rule"), which requires that consumer credit contracts (including promissory notes in consumer transactions) include a specific notice: "ANY HOLDER OF THIS CONSUMER CREDIT CONTRACT IS SUBJECT TO ALL CLAIMS AND DEFENSES WHICH THE DEBTOR COULD ASSERT AGAINST THE SELLER OF GOODS OR SERVICES OBTAINED PURSUANT HERETO." This clause effectively eliminates HDC status in covered consumer transactions. In *Stone Street Capital, LLC v. California State Lottery Commission*, the court addressed the limits of note transfer rights in a structured settlement context. **Waivers of Presentment and Notice.** The quoted clause includes a waiver of presentment, demand, protest, and notice of dishonor. These are default UCC requirements for enforcement — ordinarily, the holder must make presentment (formally demand payment) before suing on a note, and must give notice of dishonor if payment is refused. Waivers of these rights are standard in commercial notes and simply mean the lender can accelerate and sue without these preliminary steps.

A personal guaranty makes an individual personally liable for the debt of a business or another entity. It is one of the most consequential documents a business owner can sign — it pierces the liability shield of the LLC or corporation and exposes personal assets (home, savings, personal investments) to the creditor. **Unconditional vs. Limited Guaranty.** An unconditional (or "continuing") guaranty makes the guarantor liable for all debt, present and future, without limitation. A limited guaranty restricts the guarantor's liability by amount, by time period, or by specific transaction. Negotiate for a limited guaranty whenever possible — for example, capping guarantor liability at the original principal amount and excluding fees, default interest, and collection costs. **Joint and Several Liability.** When multiple guarantors sign jointly and severally, each guarantor is individually liable for the entire debt. The lender can pursue any one guarantor for the full amount, leaving that guarantor to seek contribution from co-guarantors. This is standard in commercial lending and is rarely successfully negotiated away. **Waiver of Exhaustion / Suretyship Defenses.** The quoted clause includes a waiver of the guarantor's right to require the lender to pursue the borrower (or other guarantors) before coming after the guarantor directly. Without this waiver, many states impose a suretyship rule requiring the creditor to exhaust remedies against the primary obligor first. The waiver of suretyship defenses means the lender can proceed directly against the guarantor on day one of default. **Spousal Signature Requirements.** In community property states (California, Arizona, Nevada, Texas, Washington, Idaho, Louisiana, New Mexico), a creditor seeking to reach community property assets may need the non-signing spouse to also execute a consent or guaranty. In *Orix Credit Alliance, Inc. v. Wolfe*, 212 F.3d 891 (5th Cir. 2000), the court analyzed the enforceability of a guaranty against community property assets where only one spouse signed. Whether a guaranty by one spouse reaches community property depends heavily on state community property law. **"Bad Boy" Carve-outs in Commercial Real Estate.** In real estate finance, non-recourse loans typically include "springing recourse" provisions (sometimes called "bad boy carve-outs") — the loan is non-recourse (lender can only foreclose, not sue guarantor) unless specific "bad acts" occur: fraud, misrepresentation, environmental liability, voluntary bankruptcy filing, or waste. These carve-outs convert the loan to full recourse for the guarantor if triggered. In *Chase Manhattan Bank v. Josephs*, courts enforced carve-out guaranties against principals who filed voluntary bankruptcy petitions. **Guaranty vs. Co-Maker.** A guarantor is secondarily liable (liable if the borrower fails to pay). A co-maker is directly and primarily liable — there is no secondary status. Confirm whether you are signing as a guarantor or as a co-maker on the note itself, as the distinction affects both liability priority and statute of limitations.

The ability to pay off a loan early without penalty — and the cost of doing so — significantly affects the true cost of the note and your financial flexibility. Lenders impose prepayment penalties because early repayment deprives them of expected interest income. Understanding the type and calculation of any prepayment premium is essential. **Step-Down Prepayment Premiums.** The most borrower-friendly commercial prepayment structure is a step-down premium: a percentage of the prepaid amount that decreases over time (e.g., 3% in year 1, 2% in year 2, 1% in year 3, then free thereafter). For a $1M loan, prepaying in year 1 costs $30,000 — material, but finite and predictable. **Make-Whole Premiums (Yield Maintenance).** More lender-favorable is a make-whole provision, common in commercial real estate and CMBS loans. The borrower must compensate the lender for the present value of all future interest the lender would have received through maturity, discounted at a Treasury rate. In a low-rate environment, when the loan rate significantly exceeds prevailing Treasury rates, the make-whole premium can be enormous — sometimes exceeding the remaining principal balance. In *U.S. Bank N.A. v. The Village at Lakeridge, LLC* (9th Cir. 2018), the court addressed the treatment of a make-whole premium in bankruptcy, confirming it is a damages clause that courts will enforce unless unreasonable. **"Lock-Out" Periods.** Some commercial notes prohibit prepayment entirely for an initial period (typically 1-5 years). A lock-out is absolute — no prepayment at any cost during the prohibited period. This severely restricts the borrower's ability to refinance, sell the underlying property, or exit the debt obligation. **Consumer Loan Prepayment Rights.** For residential mortgage loans subject to TILA, the prepayment terms must be disclosed. The Dodd-Frank Act (15 U.S.C. § 1639c) restricts prepayment penalties on qualified mortgages — they are prohibited after 36 months and capped at 2% in year 1 and 1% in year 2 for covered transactions. For consumer installment loans, many states impose additional restrictions on prepayment penalties. **Rule of 78s.** Some older consumer installment loans use the Rule of 78s (also called the sum-of-the-digits method) to calculate unearned interest on prepayment. Under this method, more interest is allocated to early payments, so prepaying early results in a smaller principal reduction than expected. The Rule of 78s is prohibited on consumer loans with terms over 61 months under the Truth in Lending Act (15 U.S.C. § 1615) and has been banned entirely in several states.

Before signing any promissory note, eight specific items require verification. Each represents a common source of disputes, unexpected costs, or unenforceable terms. **1. Lender Identity and Licensing.** Confirm the lender is who they claim to be and is licensed to make loans in your state if required. Consumer lenders, mortgage originators, and many commercial lenders must be licensed. Unlicensed lending may render the loan void or unenforceable under state consumer protection statutes. **2. Interest Rate vs. Usury Limit.** As detailed in Section 02, confirm the stated rate does not exceed the applicable usury limit for your state and loan type. Calculate the effective APR including fees, the 360/365-day convention, and any compound interest mechanics. **3. TILA Disclosures for Consumer Loans.** If this is a consumer loan (personal, family, or household purpose), confirm you have received the required TILA disclosures: APR, finance charge, amount financed, and total of payments. Absent required TILA disclosures, you may have rescission rights. **4. Cure Period Before Acceleration.** Confirm the note includes a cure period before the lender can accelerate on a payment default — at least 5-10 days for payment defaults and 30 days for non-payment defaults. No cure period means a single processing delay can trigger full acceleration. **5. Prepayment Rights.** Confirm whether you can prepay without penalty, and if a premium applies, calculate its cost at various prepayment dates. A make-whole provision can be prohibitively expensive. **6. Collateral Scope and UCC-1 Filing.** If the note is secured, confirm the collateral is specifically described and proportionate to the loan amount. A blanket lien on all business assets is far broader than necessary for most loans. Understand that a UCC-1 filing will be publicly visible and will encumber your assets. **7. Transfer Restrictions.** Understand whether the note is freely transferable (negotiable instrument) and whether an HDC could acquire it free of your defenses. If you want to restrict transfers, add language requiring your consent or stating the note is non-negotiable. **8. Governing Law and Dispute Resolution.** Confirm the governing law is the state where you operate or reside. Out-of-state governing law can mean litigating disputes far from home. Review whether the note includes mandatory arbitration — arbitration waives your right to a jury trial and class action rights.
