Promissory note enforcement is the process of collecting on a written promise to pay after the borrower defaults: you verify the note is valid, document the default, send a written demand, and then either negotiate a workout or file a lawsuit and pursue collection through garnishment, bank levies, or property liens. Every step runs against a statute of limitations, so the calendar matters as much as the strategy.
Confirm You Have an Enforceable Note
Before spending anything on collection, make sure the note itself will hold up. Under Article 3 of the Uniform Commercial Code, an enforceable note contains an unconditional promise to pay a fixed sum of money, is signed by the borrower, identifies who is entitled to payment, and either states a payment date or is payable on demand.1Legal Information Institute. Uniform Commercial Code 3-104 – Negotiable Instrument “Unconditional” is the requirement that trips people up. A note that says “I’ll pay $10,000 if the business turns a profit” is not unconditional. A reference to a separate agreement covering collateral or a repayment schedule is fine, provided payment itself doesn’t depend on that other document.2Legal Information Institute. Uniform Commercial Code 3-106 – Unconditional Promise or Order
A note missing any of these elements can still work as evidence of a debt, but you lose access to streamlined enforcement tools like summary judgment and open the door to more defenses.
Whether the note is secured also shapes the whole enforcement path. A secured note is backed by specific collateral you can pursue directly, often without filing a lawsuit at all. An unsecured note leaves the court system as your only route. Secured lenders generally recover more, faster, and at lower cost.
Know the Deadline Before You Act
Every promissory note has an expiration date for enforcement. Miss the statute of limitations and the borrower can have your case dismissed no matter how airtight the paperwork.
The UCC default rule is six years from the due date for a note payable at a definite time. If you accelerated the balance, the six-year clock runs from the acceleration date. For a demand note where no demand has been made and no payments received for a continuous ten-year stretch, the claim is barred entirely. States modify these periods, and the actual deadline for a written-contract lawsuit in your jurisdiction can run anywhere from three years to fifteen. Check your state’s rule early, because by the time enforcement feels necessary, the clock may already be close to zero.
Partial payment or a written acknowledgment of the debt can restart the clock in some states, but that’s a possible bonus, not a plan.
Identify the Default and Accelerate
A default is any violation of the note’s terms. The usual trigger is a missed payment of principal, interest, or both, once any grace period expires. Non-monetary defaults matter too: failing to maintain insurance on collateral, letting property taxes lapse, or transferring pledged collateral without permission can all count if the note or an accompanying security agreement requires those obligations.
Look for an acceleration clause. This is the provision letting you declare the entire remaining balance due immediately after a single missed payment. Without it, you can only sue for each unpaid installment as it comes due, which turns enforcement into a slow parade of separate filings. If the note requires written notice before acceleration, send that notice before treating the full balance as due.
Send a Written Demand
The first formal step is a demand letter. In many jurisdictions this isn’t optional, and some notes explicitly require written notice of default before you can accelerate or sue. Even where nothing requires it, courts want to see that you tried to resolve the matter before filing suit.
A useful demand letter does four things: identifies the note by its date and original amount, states the current balance including accrued interest and any late fees, gives the borrower a specific deadline to pay (10 to 30 days is typical), and makes clear you intend to pursue legal action if payment doesn’t arrive.
Send it by certified mail with return receipt requested. That creates proof of delivery you can put in front of a judge later. The letter also often works on its own. Borrowers who have gone quiet frequently respond once they see a formal written demand that signals actual intent to sue.
Consider a Workout Before Court
Not every default belongs in a courtroom. If the borrower is willing but temporarily unable to pay, a negotiated resolution can recover more money at lower cost than litigation, especially when the borrower’s assets would make a judgment hard to collect against anyway.
A forbearance agreement is the simplest form. The lender agrees to hold off on enforcement for a set period while the borrower catches up. The borrower usually pays the lender’s legal fees for negotiating the arrangement and may need to hand over updated financials or a fresh appraisal of collateral. If the borrower defaults again inside the forbearance period, enforcement rights snap back immediately.
A loan modification goes further and rewrites the note’s terms. Common changes include extending the repayment period, switching temporarily to interest-only payments, or re-amortizing the remaining balance over a longer schedule. Some modifications demand a partial paydown of principal or additional collateral in exchange for the flexibility. Whatever the terms, get the modification in writing and signed by both sides. An oral agreement to accept less or wait longer is nearly impossible to enforce later.
File the Lawsuit
When demand and negotiation fail, filing suit is the next step. The complaint sets out the facts: a valid promissory note exists, you performed your obligations under it, the borrower defaulted, and a specific amount is owed. Attach a copy of the signed note as an exhibit. The note itself is your strongest evidence.
Which court hears the case depends on how much money is at stake. Most states have small claims courts for disputes below a threshold that typically falls somewhere between $2,500 and $25,000. Larger claims go to the general civil court. Filing fees scale accordingly, and the borrower must be formally served through a neutral party such as a sheriff’s deputy or a professional process server.
Note cases are often strong candidates for summary judgment, meaning the court can rule in your favor without a trial. The note is an unambiguous written promise, and you generally only need to show the instrument and evidence of non-payment. Unless the borrower raises a genuine factual dispute, courts will grant judgment as a matter of law. Lenders with clean documentation have a real advantage here.
Anticipate the Borrower’s Defenses
Borrowers facing enforcement have options, and gauging them before you file saves money. The UCC splits defenses into two categories, and the split matters if the note has changed hands.
“Real defenses” work against anyone trying to enforce the note, including a third party who bought it in good faith. These include the borrower being a minor when they signed, duress or coercion, fraud that prevented the borrower from understanding what they were signing, illegality of the underlying transaction, and discharge in bankruptcy.3Legal Information Institute. Uniform Commercial Code 3-305 – Defenses and Claims in Recoupment
“Personal defenses” apply when the original lender is the one enforcing. These cover ordinary breach of contract, failure of consideration (the lender never actually funded the loan), improper credit of payments already made, and recoupment claims arising from the same transaction such as overcharged interest or undelivered services tied to the loan. Personal defenses can reduce or wipe out what the borrower owes, but they don’t work against a holder in due course who bought the note in good faith without knowledge of the dispute.3Legal Information Institute. Uniform Commercial Code 3-305 – Defenses and Claims in Recoupment
One defense that catches lenders off guard is accord and satisfaction. If the borrower sends a check for less than the full amount with a conspicuous notation like “payment in full,” and the lender cashes it, the rest of the debt may be discharged. This only applies when the amount owed is genuinely in dispute, but it’s a trap for lenders who deposit checks without reading the memo line.
Collect on the Judgment
Winning a judgment is not the same as getting paid. The court gives you a legal declaration of what the borrower owes; turning that into money is a separate fight, and often the more frustrating one.
Wage garnishment tends to be the most reliable tool when the borrower has steady employment. Federal law caps garnishment for ordinary debts at 25% of disposable earnings per pay period, or the amount by which weekly earnings exceed 30 times the federal minimum wage, whichever produces the smaller garnishment.4Office of the Law Revision Counsel. 15 U.S. Code 1673 – Restriction on Garnishment Some states cap it lower. Garnishment is slow, but it produces regular payments as long as the borrower stays employed.
A bank account levy lets you seize funds directly. You obtain a writ of execution from the court that entered the judgment, then have a sheriff or marshal serve the levy on the bank. A levy is a one-time grab at whatever is in the account when it’s served, not an ongoing attachment. The borrower can claim that some or all of the funds are exempt, such as Social Security benefits or other protected income. You need to know where the borrower banks, which sometimes requires post-judgment discovery.
For borrowers who own real estate, recording an abstract of judgment in the county where the property sits creates a lien against that property. The borrower can’t sell or refinance without satisfying the lien. Cash doesn’t hit your account right away, but the lien is a durable long-term hold. Filing fees for writs, levies, and lien recordings are typically recoverable as additions to the judgment.
When the Debt Is Uncollectible
Sometimes the borrower simply has nothing to take. When a personal loan becomes completely uncollectible, the tax code provides a partial consolation through the nonbusiness bad debt deduction.
The loan has to be genuinely worthless, with no realistic chance of repayment. The IRS expects documentation that you made reasonable collection efforts, whether that means demand letters, phone records, or evidence the borrower filed for bankruptcy. Having a signed note and a paper trail of collection attempts helps establish that this was a real loan and not a gift.5Internal Revenue Service. Topic No. 453, Bad Debt Deduction
A nonbusiness bad debt is treated as a short-term capital loss, regardless of how long the loan was outstanding.6Office of the Law Revision Counsel. 26 U.S. Code 166 – Bad Debts Report it on Form 8949 and attach a statement covering the details of the debt, the borrower, your collection efforts, and why the debt is worthless. The loss first offsets any capital gains for the year. If losses exceed gains, you can deduct up to $3,000 of the excess against ordinary income ($1,500 if married filing separately), with the remainder carried forward.7Office of the Law Revision Counsel. 26 U.S. Code 1211 – Limitation on Capital Losses Take the deduction in the year the debt becomes worthless. If you miss it, you generally have three years to amend the return.
