Definitions, samples, guidance and more on the complex topic of promissory notes.

A Grand Guide

Whether you’re a lender or borrower, a written promise keeps your loan agreement in check. But a sticky note won’t do—you’ll need to make something stronger than just an “IOU”. 💪

Enter: Promissory Notes

At its core, a promissory note (or a signed loan agreement) is a legally binding promise to pay a debt.

Using one can go a long way in making sure you’re paid in full and on time. Here’s everything you need to know about promissory notes, including where to get them and examples of when you might need to use them.

What we’ll cover:

What Is A Promissory Note?

Promissory notes are written loan agreements between a lender and borrower. 📃 People can use these legal documents for everything from real estate mortgages to personal loans between friends. They specify how much of the loan the borrower promises to pay back and the date you’ll pay it by. As long as a promissory note includes all key elements and is signed by both parties, it’s an official legal instrument 👩🏾‍⚖️.

9 Key Elements All Promissory Notes Should Include

While there are different types of promissory notes, all valid ones should include the following 10 elements, aka material terms:

Names and Contact Information

You’ll want the names and contact info of both parties (the lender and loan recipient).

Total Loan Amount

What’s the full amount of money, aka principal amount, the borrower owes you? Specify the currency, like USD.

Interest Rate On The Loan

Yes, even a personal loan between friends and family should include an interest rate. This makes it official and ensures you can write off any unpaid debt on your taxes in the event of nonpayment.


Include any collateral given for the loan, if applicable (you will lay this out in a section called security agreement).


A promissory note is only legally binding when signed by both parties. Otherwise, it’s just a piece of paper! ✒️

Payment Frequency, Amount & Time Frame

How will the borrower pay you? 💸 Write how often you want to be paid (monthly payments, quarterly, etc.), when the first payment will be, how much each payment should be, due dates, and the number of required principal & interest payments.

Extra Fees

This refers to any additional fees, charges, and conditions.

Date and Location

Write the date of promissory note creation and the location where it was created.


Whether or not the loan agreement is transferable. A transferable promissory note means the lender can sell the promissory note as a security and allow a third party to collect the funds.


A few real world examples on the usage of promissory notes & why they come in handy.

A promissory note is a document that you can use in a variety of situations. Loan agreements work for car loans, student loans, and institutional business loans. Here are a few examples of when you might use this type of loan agreement—and why it’s a good idea:

A business loan from a family member

Luciana wants to turn her side hustle into a fully fledged business, but she needs a little bit of capital to get her going. She runs an in-home grooming business and wants to buy a truck that she can transform into a mobile pet spa 🐩. 

Luciana’s aunt agrees to fund part of her venture with a $5,000 personal loan. Both parties sign a promissory note to confirm that Luciana will pay her aunt back in five installments over the course of 18 months.

Small Business

Or a mortgage from a bank, with a co-signer

Jake and Dom want to buy a house. To do so, they need to get a mortgage. The bank they get the mortgage from gives them a promissory note to sign. 

This loan agreement complements a legally binding mortgage note contract, and confirms the principal, interest, and timeline of payment. Jake and Dom sign to agree that they’ll repay the loan by the mortgage maturity date.


A loan to a friend in a bind

Emma and Kate are friends. They both know that can get messy 🥴. That’s why they want to use a written loan agreement while Emma lends $1,000 to Kate. 

A promissory note takes away those awkward interactions. Emma doesn’t have to ask Kate how her new job is going and whether she has the money yet. Kate is good at sticking to deadlines, so it’s a win-win. The agreement does the leg work—and Emma and Kate can focus on being pals.

Can you amend a promissory note?

Signing a loan agreement makes it official, but it’s not always the final step. In some cases, loan agreements need to be amended. How can you change the terms of your note?

Here are a few things to know when amending a promissory note:

  • You can create a legally binding addition to your loan agreement by amending the documentation and reinstating the new version.
  • Even if you change the terms of the agreement, you still need to keep the original document for reference.
  • People amend loan agreements for all kinds of reasons. Some of the reasons to amend include adding late fees, waiving prepayment fees, changing the interest or loan principal, adding a severability clause, and more.
  • In order for the amendments to become effective, both the borrower and lender must agree to the terms. 🤝🏼
  • The amended document must be signed by both parties again. Don’t rely on signatures from the original document—that won’t fly in court!
  • It’s best to create an amended loan agreement using the template or service you used for the original note. For example, if you used Pigeon for your original promissory note, use Pigeon again to amend it. This helps make sure you don’t accidentally void the document by using incorrect language or unfair terms (more on that below!).

PRO TIP: If you don’t follow these steps when amending a promissory note, your agreement may become invalid—so be sure to follow them to a T. 💯

FAQ About Promissory Notes

Answers to your most commonly asked questions about promissory notes.

What’s the difference between a secured and unsecured promissory note?

A secured promissory note requires the borrower to put up collateral 🏠. This adds an extra layer of protection for the lender as they await loan repayment. Collateral may be in the form of a hard asset (aka physical asset) like a home, rental property, or vehicle.

An unsecured loan agreement does not require collateral, but it’s still legally binding.

Is a promissory note a security?

Only companies issuing promissory notes can have promissory notes as securities (this doesn’t apply to individuals). The U.S. Securities and Exchange Commission (SEC) says promissory notes are securities if they have a maturity of at least nine months (meaning the notes themselves are 9+ months old). 

To be considered a security, a promissory note must not be secured by collateral like a mortgage, lien on a home, small business, or business asset. It also can’t be a character loan, consumer finance loan, or commercial loan.

What’s the difference between a simple and demand promissory note?

Lenders use a simple promissory note for lump sum payments. This is especially helpful for personal loans between friends and family that require a single payment.

Demand promissory notes are less common. They allow the lender to request money to be due on demand. These types of written loan agreements typically require notice ahead of time.

Custom promissory notes may have unique terms that don’t fall under either of these categories.

What is a master promissory note?

A master promissory note (MPN) is a loan agreement that covers a group of loans. MPNs almost always refer to federal student loans being paid to the U.S. Department of Education. Borrowers who receive federal student loans often receive multiple loans to help pay for the cost of school. Using an MPN means borrowers don’t have to sign a new loan agreement each school year 🎓.

Are promissory notes legit?

Most promissory notes are legitimate, but promissory note fraud is alive and well. This is usually in the case of a company’s promissory note security that is transferable for third parties to purchase. According to the SEC, “Fraudsters across the nation have recently begun to use promissory notes as vehicles to defraud investors out of hundreds of millions of dollars.” 

The SEC says to avoid insured, guaranteed, or risk-free promissory notes. Check legitimacy through federal or state securities regulators.

What is not considered a promissory note?

A promissory note is NOT a verbal agreement 🙊. These loan agreements must be written. However, it’s simple to create one once you know what elements you must include. A promissory note may accompany a contract or, in the case of a personal loan between friends and family, act in lieu of a contract.

Do I need a promissory note?

You know the saying: "It's better to be safe than sorry". These agreements are meant to protect you when things go wrong. Whether you are lending to a friend or trying to buy a house with the help of a loved one, there are numerous reasons why creating a promissory note for these agreements is a good idea.

Bottom Line

Promissory notes lay out the total loan amount, payment date and method, and other loan agreement details. At its core, it’s simple—but make sure you get it right. Use clear clauses, keep track of any changes, and always make sure to get it signed. With that, you're locked, loaded, and ready to lend 🔏.
