To enforce a promissory note, you confirm the note is valid and the borrower has defaulted, send a written demand for payment, and if that fails, file a lawsuit within your state’s statute of limitations. Winning is only half the job. Once you have a judgment, you still have to collect it through wage garnishment, a bank levy, or a lien on the borrower’s property. Secured notes give you a faster path because you can go after the collateral directly. Every step has a deadline, and lenders who wait too long lose the right to sue at all.
Confirm the Note Is Enforceable
Before spending money on collection, make sure the document in your hand actually qualifies as a negotiable instrument under Article 3 of the Uniform Commercial Code. The note needs an unconditional promise to pay a fixed sum of money, a payment date or on-demand language, the borrower’s signature, and an identified payee. “Unconditional” means the obligation to pay cannot hinge on some outside event. A note saying “I’ll pay $10,000 if the business turns a profit” fails that test. Referring to a separate agreement for collateral or a payment schedule is fine, as long as payment itself is not contingent on that agreement.1Legal Information Institute. Uniform Commercial Code 3-106 – Unconditional Promise or Order
If the note is silent about when payment is due, the UCC treats it as payable on demand, meaning you can call it due at any time.2Legal Information Institute. Uniform Commercial Code 3-104 – Negotiable Instrument A note missing one of these elements may still work as evidence of a debt, but you lose access to expedited procedures like summary judgment and give the borrower more room to raise defenses.
Confirm the Default and Whether You Can Accelerate
A default happens the moment the borrower violates the note. The usual trigger is a missed payment of principal or interest, either after any grace period the note allows or immediately if none is specified. Defaults can also be non-monetary: if the borrower is required to keep insurance on collateral, pay property taxes, or refrain from transferring pledged property, breaking any of those obligations counts.
Check whether the note contains an acceleration clause. That single provision lets you declare the entire remaining balance due after even one missed payment. Without it, you can only sue for each installment as it comes due and goes unpaid, which turns collection into a series of small, repeated lawsuits. If the note requires written notice of default before you can accelerate, follow that requirement exactly. Skipping the notice step gives the borrower a procedural defense that can derail the case.
Check the Deadline to Sue
Every promissory note has an expiration date for enforcement. The statute of limitations sets the window during which you can file suit, and once it closes, the borrower can have the case dismissed no matter how clean the paperwork is.
The UCC’s default rule gives you six years from the due date to file. If you accelerated the balance, the six years run from the acceleration date. For a demand note where no demand was ever made and no payments were received for ten straight years, the claim is barred outright. States often modify these periods. The actual limitation on a written-contract lawsuit ranges from three to fifteen years depending on where you are. Check your state’s rule before doing anything else, because a lender who realizes they need to sue often finds the clock already close to running out. Partial payments or a written acknowledgment of the debt can restart the clock in some states, but that isn’t a strategy to rely on.
Send a Demand Letter
Formal collection starts with a written demand for payment. Courts want to see that you tried to resolve the matter before filing suit, and many notes explicitly require written notice of default before you can accelerate. A useful demand letter identifies the note by date and original amount, states the current balance including accrued interest and late fees, and sets a specific deadline for payment, typically 10 to 30 days. It should say plainly that you will pursue legal action if the deadline passes.
Send it by certified mail with return receipt requested. That creates proof the borrower received it, which matters in court. A demand letter also often works on its own. Borrowers who have gone quiet frequently respond when they see a formal written demand that signals real intent to sue.
Try a Workout Before Litigation
Not every default belongs in court. If the borrower is willing but unable to pay in full right now, a negotiated arrangement can recover more money than a lawsuit, especially when the borrower’s assets are limited enough that a judgment would be hard to collect on anyway.
A forbearance agreement is the simplest option. You agree to hold off on enforcement for a defined period while the borrower catches up on missed payments. The borrower typically covers your legal fees for the agreement and may need to provide updated financial information. If the borrower defaults again during the forbearance period, your enforcement rights snap back in full.
A loan modification goes further by formally changing the note’s terms. Common changes include extending the repayment period, switching temporarily to interest-only payments, or re-amortizing the balance over a longer schedule. Some modifications require a partial paydown or additional collateral in exchange for the flexibility. Any change needs to be in writing and signed by both parties. An oral agreement to accept less or wait longer is almost impossible to enforce if the arrangement later falls apart.
Enforce Against Collateral for a Secured Note
If your note is secured, you have a separate and often faster path. A secured note is backed by specific property, called collateral, that you can seize on default. An unsecured note has no such backing, so your only route is the court system.
For personal property, your security interest needs to be perfected to hold up against other creditors. Under Article 9 of the UCC, perfection usually means filing a UCC-1 financing statement with the appropriate state office. For real property, you record a mortgage or deed of trust with the county recorder. When the borrower defaults, you can often pursue the collateral directly without filing a lawsuit first, depending on the type of property and the terms of the security agreement. Secured lenders typically recover more money, faster, and with lower legal costs than unsecured lenders.
File a Lawsuit
When demands and negotiations fail, file a complaint in the appropriate court. The complaint should state that a valid note exists, that you performed your obligations, that the borrower defaulted, and that 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 the amount. Small claims courts handle disputes up to a threshold that generally falls between $2,500 and $25,000 depending on the state. Larger amounts go to general civil court. The borrower must be served with the lawsuit through a neutral party such as a sheriff’s deputy or a professional process server.
Note cases are strong candidates for summary judgment, which lets a court rule in your favor without a full trial. Because a note is an unambiguous written promise to pay, you generally only have to present the note and evidence of non-payment. Unless the borrower can point to a genuine factual dispute, the court can grant judgment as a matter of law. Cases with clean documentation often resolve in weeks rather than months.
Anticipate the Borrower’s Defenses
Borrowers do have options, and knowing what they might raise helps you assess your position before filing. The UCC splits defenses into two categories.
“Real defenses” work against anyone enforcing the note, including a third party who bought it in good faith. They include the borrower being a minor at signing, duress, fraud that prevented the borrower from understanding what they signed, 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 the note. These include ordinary breach of contract, failure of consideration (you never actually provided the loan funds), or a claim that the borrower paid and you failed to credit the payments. A borrower can also raise a recoupment claim from the same transaction, arguing that you overcharged interest or failed to deliver promised services tied to the loan. Personal defenses can reduce or wipe out what the borrower owes, but they do not work against a holder in due course who purchased the note in good faith without knowledge of the dispute.3Legal Information Institute. Uniform Commercial Code 3-305 – Defenses and Claims in Recoupment
Watch for accord and satisfaction. If the borrower sends a check for less than the full amount with a conspicuous notation such as “payment in full,” and you cash it, the remaining debt may be discharged. This only applies when the amount owed is genuinely in dispute, but it catches lenders who deposit checks without reading them.
Collect on the Judgment
A judgment is not money. It is a court declaration that the borrower owes you a specific amount. Turning that piece of paper into cash requires separate collection steps, and this is where many lenders find the process harder than the lawsuit itself.
Wage garnishment is often the most reliable tool when the borrower has steady employment. Federal law caps garnishment for ordinary debts at 25% of the borrower’s 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 set lower limits. It is slow, but it produces regular payments as long as the borrower stays employed.
A bank account levy seizes funds directly from the borrower’s account. You obtain a writ of execution from the court that entered the judgment and coordinate with a sheriff or marshal to 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 push back by claiming that some or all of the funds are exempt, such as Social Security benefits. You need to know where the borrower banks, which sometimes requires post-judgment discovery.
If the borrower owns real estate, recording an abstract of judgment in the county where the property sits creates a lien. The borrower cannot sell or refinance without satisfying the lien first. It does not produce cash immediately, but it is a powerful long-term tool. Filing fees for writs, levies, and lien recordings are typically recoverable as additions to the judgment.
Write Off What You Cannot Collect
When the borrower simply does not have the money, the tax code offers a partial consolation for personal loans through the nonbusiness bad debt deduction. The loan must be genuinely worthless, with no realistic chance of repayment. The IRS wants documentation that you made reasonable collection efforts: demand letters, phone records, or evidence that the borrower filed for bankruptcy. A signed promissory note and records of your attempts strengthen the position 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 with an attached statement explaining 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), and any remaining loss carries 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.
