A payment note, more commonly called a promissory note, is a written and legally binding promise from one party to repay a specific sum of money to another on agreed terms. It converts a verbal arrangement into an enforceable contract that spells out the amount owed, the interest rate, the payment schedule, and the consequences of missing a payment. The borrower is called the maker; the lender is called the payee. Done properly, the document is enforceable in court and can even be sold to a third party.
How It Differs From an IOU
People use “promissory note” and “IOU” interchangeably, but the legal gap between them is wide. An IOU acknowledges that money is owed and stops there. A payment note contains an unconditional promise to pay a fixed sum, on a specific schedule, with defined consequences for failing to do so.
That difference has real weight. A properly drafted payment note qualifies as a negotiable instrument under Article 3 of the Uniform Commercial Code, which every state has adopted in some form. Negotiable status means the note can be transferred to a new holder who then has the legal right to collect, even if the original lender is out of the picture. An IOU cannot do that. For any meaningful sum, a note is the right document.
What a Valid Note Must Contain
The document doesn’t have to be long, but certain elements need to be there. Missing one can reduce the note to an ordinary contract or make it unenforceable.
- Full legal names and contact information for the maker and the payee.
- The principal amount, stated in both numbers and words to prevent disputes.
- The annual interest rate, which must sit within the state’s usury limits.
- The repayment schedule: monthly installments, a lump sum at maturity, or payable on demand.
- A definite maturity date, which is one of the requirements for negotiability.
- The maker’s signature. Without it, no one is liable on the instrument.
Most well-drafted notes also include an acceleration clause. That provision lets the lender declare the entire remaining balance due immediately after a missed payment or a bankruptcy filing, rather than waiting for each installment to come due. Late fees should be spelled out too, either as a percentage of the overdue installment or a flat dollar amount. Whatever penalty you set has to be reasonable, because courts will refuse to enforce a late fee that looks more like a punishment than compensation for the lender’s actual costs.
Interest Rate Rules You Have To Follow
Every state caps how much interest a lender can charge, and the ceiling varies by loan type, loan amount, and who the parties are. Charging above the cap is usury, and the penalty can range from forfeiting the excess interest to voiding the loan entirely. If you are drafting a private note, check your state’s specific limits before choosing a rate.
The Applicable Federal Rate Floor
Even on informal loans between family or friends, the IRS requires you to charge at least the Applicable Federal Rate, which it publishes monthly. For January 2026, the annual rates are 3.63% for short-term loans (up to three years), 3.81% for mid-term loans (three to nine years), and 4.63% for long-term loans (over nine years).1Internal Revenue Service. Revenue Ruling 2026-2 Charge less than the AFR, or nothing at all, and the IRS treats the gap as “forgone interest.” That phantom interest is taxed as if the lender actually received it, and the forgone amount may also count as a gift from the lender to the borrower.2Office of the Law Revision Counsel. 26 US Code 7872 – Treatment of Loans with Below-Market Interest Rates
There is a de minimis exception. If the total outstanding loans between you and another individual stay at or below $10,000, the imputed interest rules generally don’t apply. That exception disappears if the borrower uses the money to buy income-producing assets like stocks or rental property.2Office of the Law Revision Counsel. 26 US Code 7872 – Treatment of Loans with Below-Market Interest Rates
Reporting the Interest
Interest of $10 or more received during the year has to be reported to the IRS. Institutional lenders file Form 1099-INT with the borrower’s information.3Internal Revenue Service. Instructions for Forms 1099-INT and 1099-OID Private lenders between individuals aren’t always required to issue a 1099-INT, but the interest is still taxable income and belongs on the lender’s return. Borrowers can generally deduct mortgage interest on a secured note but cannot deduct interest on a personal loan.
The Main Types of Payment Notes
Secured or Unsecured
A secured note is backed by collateral. In real estate, the payment note and the mortgage (or deed of trust) work as a pair. The note creates the obligation to repay, and the mortgage gives the lender the right to seize and sell the property if the borrower defaults.4U.S. Securities and Exchange Commission. Promissory Note Secured by Deed of Trust This dual-document structure is standard in home purchases, commercial real estate, and many car loans.
An unsecured note has nothing pledged behind it. Private loans between friends, some business financing, and commercial paper issued by large corporations to raise short-term capital all typically use unsecured notes. The lender’s only remedy on default is suing for a money judgment against the borrower’s general assets, which makes the risk substantially higher.
Recourse or Non-Recourse
This distinction matters most when a secured note goes bad and the collateral won’t cover the debt. With a recourse note, the lender can pursue the borrower personally for the shortfall through wage garnishment or bank levies. With a non-recourse note, the lender’s recovery is limited to the collateral itself.5Internal Revenue Service. Cancellation of Debt – Basics – Recourse vs Nonrecourse Debt Whether a loan is recourse or non-recourse depends on the note’s terms and state law, and that single detail can decide whether a borrower walks away or ends up owing a large deficiency balance.
Demand or Term
A term note has a fixed schedule and a definite maturity date. A demand note has no set due date; the lender can call the entire balance due at any time by giving notice. Demand notes turn up in lines of credit and some business lending. They give lenders flexibility and leave borrowers exposed to being called on at any moment.
Transferring a Note to Someone Else
The lender doesn’t have to wait years to collect. The note itself is an asset that can be sold, usually at a discount, to an investor who buys the right to receive the remaining payments.
Transfer happens through endorsement. The current holder signs the back of the note, much like a check. A blank endorsement, where the holder simply signs without naming anyone, turns the note into a bearer instrument that whoever physically holds it can collect on. A special endorsement names a specific new payee, and only that party can collect or further transfer the note. Special endorsements are safer, because a lost or stolen note with a blank endorsement is effectively cash in the wrong hands.
The new holder steps into the original lender’s shoes. The strongest position that holder can reach is “holder in due course” status, which requires paying value for the note, acting in good faith, and having no knowledge of any problems with the instrument at the time of purchase. That status strips away most defenses the borrower could have raised against the original lender. Only a narrow set survives: fraud that tricked the borrower into signing without understanding what the document was, infancy, duress, illegality, and discharge in bankruptcy.6Legal Information Institute. UCC 3-305 – Defenses and Claims in Recoupment Borrowers who assume a dispute with the original lender lets them stop paying sometimes learn the hard way that the note has been sold to someone immune to that argument.
What Happens if the Borrower Defaults
Default usually means a missed payment, but the note itself defines what counts. Some notes treat a missed insurance payment or a drop in collateral value as a default event too.
The lender’s first move is typically to invoke the acceleration clause, so the entire unpaid balance becomes due immediately. What follows depends on whether the note is secured.
On an unsecured note, the lender sues for a money judgment covering the balance, accrued interest, and late fees. With a judgment in hand, the lender can pursue wage garnishment, bank levies, and property liens, all subject to state exemption laws that shield certain assets and income.
On a secured mortgage note, the lender forecloses. Depending on the state, that runs through the courts (judicial foreclosure) or through a trustee sale with no court involvement (non-judicial foreclosure). Either way, the property is sold and the proceeds are applied to the debt. If the sale falls short, the shortfall is a deficiency. On a recourse note, the lender can seek a deficiency judgment and then pursue the borrower’s other assets and income. Most states allow this, though a handful, including Alaska, California, Minnesota, Montana, Oregon, and Washington, prohibit deficiency judgments in most circumstances. On a non-recourse note, the lender absorbs the loss.5Internal Revenue Service. Cancellation of Debt – Basics – Recourse vs Nonrecourse Debt
How Long the Lender Has To Sue
A lender does not have forever. Under the UCC, the statute of limitations on a note payable at a definite time is six years from the stated due date. If the lender accelerated after default, the six-year clock runs from the acceleration date instead.7Legal Information Institute. UCC 3-118 – Statute of Limitations
Demand notes work differently. The six-year period starts when the lender actually makes a demand. If no demand is ever made, the note becomes unenforceable after ten continuous years with no payment of principal or interest.7Legal Information Institute. UCC 3-118 – Statute of Limitations Some states have adjusted these windows, so confirm the local rule. The core point holds either way: a lender who sits on a defaulted note too long loses the ability to collect through the courts.
Paying the Note Off
When the borrower makes the last payment, the obligation is discharged. Under the UCC, the instrument is considered paid to the extent that payment is made by the party who owes the debt to the person entitled to enforce it.8Legal Information Institute. UCC 3-602 – Payment In practice, the borrower should get the original note back marked “paid in full,” or receive a written satisfaction. For mortgage notes, the lender also has to record a release or satisfaction with the county recorder to clear the lien from the property’s title.
One trap catches borrowers off guard. If the note has been transferred, paying the original lender does not necessarily discharge the debt. Payment has to go to whoever currently holds the note. Once the borrower receives proper written notice of the transfer and instructions on where to send future payments, continuing to pay the old lender won’t count.8Legal Information Institute. UCC 3-602 – Payment Before making a final payoff, confirm who holds the note, especially on any loan that may have been sold in the secondary market.
