Writing a Debt Agreement Letter [Free Samples]

A debt agreement letter is a legally binding contract between someone who borrows money, the promisor, and the person who lends the money, the payee. The letter should include how and when the repayments will be made as well as any penalties if the promisor defaults on debt payments. 

If it is properly written, the letter can be used as evidence in court if it becomes necessary for the payee to go to court to get the money back. 


It’s a good idea to write a debt agreement letter whenever a person loans money even to a family member, friend or colleague. Loaning money is a business transaction and should be treated as such. The letter will eliminate any possibility of confusion later.

Debt Agreement Will Protect Payee And Promisor

This letter will protect both the payee as well as the promisor. The payee wants legal proof that they loaned the money and that the promisor agreed to repay it. 

The promisor wants legal proof of how much they borrowed, so the payee cannot claim the amount was higher at a later date.


It is recommended to sign the letter in front of a notary. This may require a small fee. If it is not possible, then witnesses should also sign the letter. A copy should be made so both the promisor and payee has one.

If the debt agreement letter is between business partners or for official loans, the amount of interest that will be charged for the duration of the loan should be mentioned. For loans between friends, interest is often not charged, but should be mentioned if it is charged.

The letter should be very concise to avoid confusion. It should include:

  1. The legal name of both the promisor and the payee
  2. The total amount of the loan
  3. The terms of the repayment
  4. What the payments are for
  5. When the payments are due
  6. How the payments will be made
  7. When the last payment should be made
  8. Any penalties for defaulting
  9. Any grace period for late payments

The letter should have a signatory area at the bottom, and it is recommended that there be space for a witness signature for each side. The format should be accurate if it is to be seriously considered in the event the payee needs to go to court.

Two Main Types Of Debt Agreement Letters

The two main types of debt agreement letters are for a lump sum and for a payment plan. The information at the beginning and end of the letters is the same. Only the body of the letter is different. Here are samples of each type of debt agreement letter.


If a notary is not used, the letter can be sent by certified mail by the payee or promisor to themselves. This will give the time and date the letter was signed. This may be crucial information if the payee takes the promisor to court.
