Promissory Note

A promissory note is a written promise to pay a specific amount of money to a specific person or business by a certain date. It's a legally binding document that spells out the loan amount, interest rate, payment schedule, and what happens if you default. Think of it as a formal, enforceable IOU.

Promissory Note Definition

A promissory note is a written promise to pay a specific amount of money to a specific person or business by a certain date. It's a legally binding document that spells out the loan amount, interest rate, payment schedule, and what happens if you default. Think of it as a formal, enforceable IOU.

Promissory Note in Practice — Example

A small business owner borrows $25,000 from a family friend to open a food truck. They draft a promissory note stating the principal ($25,000), interest rate (5% annual), monthly payment amount ($477), and repayment term (5 years). Both parties sign it. The note protects the lender legally and gives the borrower clear terms to follow. If a dispute arises, the promissory note serves as evidence in court.

Why Promissory Note Matters for Your Business

Promissory notes formalize lending relationships and protect both sides. Whether you're borrowing from a bank, investor, or friend, a promissory note creates clarity and accountability. Without one, disagreements about terms can damage relationships and create legal headaches.

For businesses raising money informally — from friends, family, or angel investors — a promissory note is essential. It turns a handshake agreement into an enforceable contract. Banks require promissory notes for virtually every loan they make, and the SBA requires them for all SBA-backed loans.

Types of promissory notes:

  • Secured: Backed by collateral (equipment, real estate)
  • Unsecured: No collateral; based on borrower's creditworthiness
  • Demand: Payable whenever the lender demands it
  • Installment: Paid in regular installments over time
  • Promissory Note vs Loan Agreement

    A promissory note is a one-sided promise from the borrower to repay. A loan agreement is a more comprehensive two-sided contract that includes the lender's obligations, covenants, representations, and more detailed terms. Bank loans typically include both — you sign a loan agreement and a promissory note.

    FAQ

    Q: Is a promissory note legally enforceable?

    A: Yes. A properly executed promissory note is a legally binding document. If the borrower defaults, the lender can use it to pursue legal remedies, including court judgments.

    Q: Do I need a lawyer to create a promissory note?

    A: For simple notes between individuals, templates can work. But for significant amounts or complex terms, having a lawyer draft or review the note is well worth the cost.
