How to Write a Demand Letter

One clear letter settles many disputes, and it can be a required step before you sue.

Last checked November 1, 2026 · 4 minute read

The short answer

Say what happened, how much you want, and the date you want it by. Keep it factual, send it in a way you can prove, and keep a copy.

Why send one

A letter shows you tried to resolve it, gives the other side a clear deadline, and often ends the dispute. Courts may also expect you to have asked.

California

The claim form asks you to confirm you asked for payment where possible. You can ask in person, in writing or by phone. The state guide excuses this if there is a restraining order between you or asking would be dangerous.

Nevada

No statewide rule requires a demand. Las Vegas Justice Court says you must have asked, and a call, email, text or letter can count. The state's self-help center says most townships want a certified letter, so check your court.

What to include

Keep it calm

Stick to facts. Don't threaten to report anyone to the police or an agency to get paid, and don't call anyone names. A judge may read this letter.

Send it so you can prove it

Certified mail with a return receipt gives you proof. Keep a copy, the receipt and any reply together.
