Why document a personal loan in writing?

Even loans between family members and close friends should be documented in writing. A promissory note protects both parties: it proves the lender is owed repayment (not making a gift), establishes the agreed interest rate and repayment schedule so there are no misunderstandings, and creates legal documentation if the borrower fails to repay. The IRS also requires certain documentation for family loans to avoid gift tax complications. A written promissory note is far cheaper than a lawsuit to prove you made a loan years after the fact.

How a Promissory Note Works

A promissory note is a negotiable instrument — a written promise to pay that creates an enforceable legal obligation. Unlike a verbal agreement, a signed promissory note is nearly impossible to dispute in court if the borrower later claims they never agreed to repay the money or disagrees about the terms. The note creates a complete written record of the loan amount, interest rate, repayment schedule, and consequences of default.

Promissory notes come in several forms. A lump-sum note (also called a balloon note) requires repayment of the entire principal and accrued interest on a single future date — common for short-term loans between family members. A monthly installment note spreads repayment over a term with fixed monthly payments — the same structure used for mortgages and car loans. An on-demand note has no fixed repayment date — the lender can demand repayment at any time with reasonable notice.

For monthly installment notes, each payment is allocated first to accrued interest and then to principal. This means that in the early payments, more goes toward interest; in the later payments, more goes toward principal. The total interest paid over the life of the loan depends on the rate and term — a 6% rate on a $5,000 loan over 12 months results in estimated total interest of about $163.

Worked Example: Family Loan

David Kim lends his daughter Sarah Kim $15,000 to help cover her down payment on a first home. They want to document it properly to avoid confusion and IRS gift tax issues.

Loan Amount: $15,000
Interest Rate: 4% per annum (above AFR minimum)
Repayment: Monthly installments over 36 months
Monthly Payment: $442.95 (calculated automatically)
Governing State: Washington
Total Interest: ≈$946

Both David and Sarah sign the note. David retains the original; Sarah keeps a copy. Because the interest rate exceeds the IRS Applicable Federal Rate, the IRS will not treat the loan as a taxable gift. The promissory note also protects David's estate — if he passes away during the loan term, the outstanding balance is a documented asset of his estate rather than a disputed gift.

Key Factors for a Legally Sound Promissory Note

  • Interest rate compliance. Verify that your interest rate does not exceed your state's usury limit. For family loans, also consider the IRS Applicable Federal Rate — loans at below-market rates may trigger imputed interest rules. Setting the rate at or above the current AFR avoids this complication.
  • Acceleration clause. Include a clause that makes the entire balance due immediately upon default. Without an acceleration clause, a lender can only sue for missed payments one at a time rather than the entire outstanding balance.
  • Governing state. Specify a governing state whose laws are favorable and where you would realistically sue to enforce the note. Usury limits vary significantly by state.
  • Witness or notarization. While not always legally required, having the promissory note witnessed or notarized provides additional evidence of authenticity and can make enforcement easier if the borrower later disputes signing it.

Frequently Asked Questions

What is a promissory note?

A promissory note is a legally binding written promise by a borrower to repay a loan to a lender under specified terms. It documents the principal amount, interest rate, repayment schedule, and what happens if the borrower defaults. Promissory notes are used for personal loans between family members or friends, private business loans, seller-financed real estate purchases, and many other lending situations. Unlike a mortgage or deed of trust, a basic promissory note is unsecured — there is no collateral pledged — though a secured promissory note can include a pledge of collateral.

Is a promissory note legally enforceable?

Yes. A promissory note is a legally binding contract that is enforceable in court. If a borrower fails to repay a promissory note, the lender can sue to obtain a civil judgment for the amount owed, plus interest, late fees, and in some cases attorney's fees. A signed promissory note creates clear evidence of the debt — which is essential in any legal action to collect. Without a written promissory note, proving that a personal loan (rather than a gift) was made becomes much more difficult in court. The note should be signed by the borrower and dated.

How is interest calculated on a promissory note?

Most promissory notes use simple interest, which means interest accrues only on the outstanding principal balance — not on previously accrued interest. The monthly interest amount equals the annual rate divided by 12, multiplied by the outstanding principal. For installment loans, each payment is first applied to accrued interest, then to principal — so the interest portion decreases over time as the principal is paid down. Our promissory note generator automatically calculates the estimated monthly payment using the standard amortization formula based on your loan amount, interest rate, and term.

What are usury laws and how do they affect my promissory note?

Usury laws limit the maximum interest rate a lender can legally charge. These laws vary significantly by state — some states cap rates at 6-10% for written contracts while others allow much higher rates. Charging interest above the usury limit can make the interest provisions of a promissory note unenforceable, and in some states constitutes a criminal offense. For loans between family members at reasonable rates, usury laws are rarely an issue. For larger loans at higher rates, verify your state's usury limit before finalizing the note. The IRS also has rules about minimum interest rates for family loans — loans below the Applicable Federal Rate may be treated as gifts.

What happens if the borrower defaults on a promissory note?

If a borrower defaults, the note's acceleration clause typically makes the entire remaining balance immediately due and payable. The lender can then pursue collection through the courts — filing a civil lawsuit to obtain a judgment. Once a judgment is obtained, the lender can garnish the borrower's wages, levy bank accounts, or place liens on property. For secured notes with collateral, the lender may also repossess or foreclose on the collateral. The specific remedies available depend on state law and the terms of the note. For smaller amounts, small claims court is an efficient option in most states.
