A client won’t pay your invoice. A friend borrowed money and stopped answering. A former landlord kept your security deposit. Before you go to small claims court, there’s one step that often gets results on its own: a demand letter.
A demand letter is a formal, written request for payment. It shows you’re serious, gives the other person a last chance to pay, and creates a record you can use later if you need to go to court. In many small claims courts, sending a demand first is expected or even required.
Note: This guide is general information, not legal advice.
When Should You Send a Demand Letter?
- Unpaid invoices for work or products
- Personal loans that weren’t repaid
- Security deposits not returned
- Bounced checks
- Property damage someone agreed to pay for
- Refunds a business promised but never sent
Before You Write
- Calculate the exact amount owed. Include only what you can prove.
- Gather evidence: contracts, invoices, receipts, texts, emails, bank transfers, photos.
- Check your deadline. Every state has time limits (statutes of limitation) for bringing claims. Don’t wait.
- Check the small claims limit in your state, in case you need to file.
What to Include
- Your name and contact information
- The debtor’s name and address
- A clear subject line, e.g. “Demand for Payment of $1,250”
- A short summary of the facts: what was agreed, what you did, what they failed to do
- The exact amount owed and how you calculated it
- A firm deadline to pay (often 10–14 days)
- How to pay you
- What you’ll do if they don’t pay, such as filing in small claims court
- A professional, calm tone

Tips for an Effective Demand Letter
- Stay professional. No insults or threats beyond lawful next steps. Remember, a judge may read this letter.
- Be specific. Exact dates, amounts and documents.
- Only threaten what you will actually do. Making threats you don’t intend to follow through on weakens your position.
- Send it with proof of delivery, such as certified mail with return receipt, and also by email if you usually communicate that way.
- Keep copies of everything.
- Be open to a payment plan. Getting paid in installments is often better than a court judgment you then have to collect.
What If They Still Don’t Pay?
- Small claims court: relatively quick and inexpensive, and you usually don’t need a lawyer. Your demand letter becomes part of your evidence.
- Mediation: many communities offer low-cost mediation services.
- Collection agency or attorney: for larger amounts or business debts.
Frequently Asked Questions
Does a demand letter have to come from a lawyer?
No. You can write and send it yourself. A letter from an attorney can carry extra weight, but it isn’t required.
How long should I give them to pay?
Ten to fourteen days is common and generally seen as reasonable.
Can I charge interest?
Only if your contract allows it or the law in your state permits it. If you’re unsure, ask only for the principal amount you can prove.
