How to Write a Demand Letter for Payment
What a demand letter is and when to send one
A demand letter is a written request for payment that you send to someone who owes you money before you take them to small claims court or hire a lawyer. It is not a legal threat—it is a record that you asked for the money in writing, gave the person a deadline to pay, and documented what they owed and why. Courts and debt collectors use demand letters as proof that you made a good-faith effort to resolve the debt without going to court.
You send a demand letter when someone has not paid you after you have asked them verbally or through text or email. It works best for debts between people you know—a roommate who did not pay their share of rent, a friend who borrowed money, a contractor who did not finish a job you paid for—or for small debts from businesses. If you are owed money by a company that is ignoring you, a demand letter creates a paper trail that helps if you later file in small claims court or report them to your state's attorney general.
Do not send a demand letter if you are trying to collect a debt you are not sure you are owed, or if the person has already told you they dispute the debt. A demand letter assumes the debt is real and only the payment is in question.
Key Takeaways
- A demand letter is a written request for payment that creates a record you tried to resolve the debt before court, and it must include the amount owed, why it is owed, and a deadline to pay.
- Send the letter by certified mail with return receipt so you have proof the person received it, and keep a copy for your records.
- The deadline you give should be reasonable—usually 10 to 30 days—and you should state what you will do if they do not pay (small claims court, report to a collection agency, or report to credit bureaus).
- A demand letter does not require a lawyer and costs only the price of postage, but it only works if the person has the money to pay and is willing to respond to written requests.
- If the person does not pay after the deadline, you can use the letter as evidence in small claims court or to show a debt collector that you made a good-faith effort to collect.
What to include in your demand letter
Your demand letter should be short, clear, and factual. It does not need to be formal or written by a lawyer—a plain letter works just as well in court. Include these pieces of information in this order: your name and address, the date you are sending the letter, the name and address of the person or business that owes you money, the exact amount owed in dollars and cents, the reason they owe it (a loan, unpaid rent, damaged property, unpaid invoice), the date the debt became due or the date you first asked for payment, and the date by which they must pay you.
At the end, state what you will do if they do not pay by that date. You might write: "If I do not receive payment by [date], I will file a claim in small claims court" or "I will report this debt to a collection agency" or "I will report this debt to the credit bureaus." Be honest about what you actually plan to do—do not threaten to sue if you do not mean it, because a court will see that as bad faith.
Do not include insults, threats, or emotional language. Do not write "You are a liar" or "I will destroy your credit" or "You better pay or else." Courts take these as signs that you are not being reasonable, and they can hurt your case. Stick to facts: the amount, the reason, the date it was due, and the deadline to pay.
A template you can use
Here is a basic template. Fill in the bracketed parts with your own information:
[Your Name] [Your Address] [City, State ZIP] [Date]
[Debtor's Name] [Debtor's Address] [City, State ZIP]
Dear [Debtor's Name],
I am writing to demand payment of $[amount] that you owe me. On [date], you [reason for debt: borrowed this money / agreed to pay this invoice / damaged my property / failed to complete work I paid for]. You agreed to pay by [original due date], but I have not received payment.
I have asked you for payment [number of times] on [dates], and you have not responded. I am giving you until [date 10–30 days from today] to pay this debt in full. Payment should be sent to [your address or payment method].
If I do not receive payment by [date], I will pursue this debt through small claims court [or: report this to a collection agency / report this to the credit bureaus].
Sincerely, [Your Signature] [Your Printed Name]
How to send your demand letter
Send your letter by certified mail with return receipt requested. This costs a few dollars extra at the post office, but it gives you proof that the person received the letter. The post office will mail you a card showing the date they signed for it. Keep that card—it is your evidence that they got the letter and had time to respond.
Do not send the letter by regular email or text, because the person can claim they never saw it. If you email it, also send a printed copy by certified mail. Keep a copy of the letter for yourself, and keep the certified mail receipt and return card in a folder with any other documents about the debt (texts, emails, photos, receipts, invoices, loan agreements).
If you do not know the person's address, you can sometimes send the letter to their workplace or to an address you have on file. If you cannot find them, you may not be able to send a demand letter, and you should talk to a lawyer or your local small claims court about your options.
What happens after you send the letter
After you send the letter, wait for the deadline you set to pass. Some people will pay once they see a formal written demand—it signals that you are serious. Others will ignore it. If they do not pay by the deadline, you have a few options: file in small claims court (which costs between $50 and $300 depending on your state and the amount owed), report the debt to a collection agency (which will try to collect on your behalf, usually for a percentage of what they recover), or report the debt to the credit bureaus if the person is a consumer (though this works best if the debt is over $100 and they have a credit file).
If you do go to small claims court, bring the demand letter, the certified mail receipt, the return card, and any other proof of the debt. The letter shows the judge that you tried to resolve this without court, which makes your case stronger.
When a demand letter will not work
A demand letter only works if the person has money to pay and is willing to respond to written requests. If the person is judgment-proof (they have no income or assets you can collect from), a demand letter will not get you paid, though it may still be worth sending for your records. If the person is out of the country, in hiding, or has a history of ignoring all communication, a demand letter is unlikely to result in payment.
A demand letter also will not work if the debt is disputed. If the person has told you they do not owe the money, or if there is a real disagreement about whether they owe it, a demand letter assumes they are wrong and only the payment is in question. In that case, you may need to go straight to small claims court or talk to a lawyer about whether you have a case.
Frequently Asked Questions
Do I need a lawyer to write a demand letter?
No. A demand letter is a simple written request and does not require legal language or a lawyer's signature. You can write it yourself using the template above. If the debt is large or complicated, you might want a lawyer to review it, but for most debts under $5,000, a plain letter works just as well in court.
How long should I give them to pay?
Usually 10 to 30 days is reasonable. The shorter the deadline, the more aggressive the letter feels. If you want to seem willing to work with them, give 30 days. If you want to signal that you are serious, give 10 to 14 days. Do not give less than 10 days unless there is a reason (like they promised to pay by a specific date and broke that promise).
What if they pay after the deadline but before I go to court?
Take the payment. Once they pay, the debt is settled and you have no reason to go to court. Make sure you get the payment in full and in a form you can prove (check, bank transfer, or money order—not cash). Send them a written receipt saying the debt is paid in full.
Can I send a demand letter by email or text?
You can, but certified mail is stronger because it creates proof they received it. If you email or text, also send a printed copy by certified mail. Courts prefer certified mail because it is harder to deny you sent it or that they received it.
What if the person says they will pay but keeps not paying?
After the deadline passes, you do not have to wait any longer. You can file in small claims court or report the debt to a collection agency. Do not send another demand letter—you have already given them a chance to pay, and they did not.
