A demand letter is a formal written notice to the other party that you intend to file a lawsuit if they don't resolve your dispute. Whether you're legally required to send one depends on your state.
States that require demand letters: California requires a demand letter for most small claims cases. Some other states have similar requirements, particularly for consumer disputes.
Even when not required, send one anyway. Here's why: A demand letter serves multiple purposes. First, it often gets you paid without going to court — many people and businesses will resolve a legitimate dispute rather than face the hassle of litigation. Second, if you do end up in court, the letter shows the judge you tried to resolve the matter in good faith. Third, it establishes a paper trail and a clear timeline.
What a demand letter should include:
- Your name and contact information
- The recipient's name and address
- A clear description of the dispute and what happened
- The specific amount you're demanding
- A deadline for payment or response (typically 10-30 days)
- A statement that you will file suit if the matter isn't resolved
Send it via certified mail with return receipt requested. Keep a copy of the letter and the delivery confirmation — you may need to present them in court.
Keep the tone professional. A demand letter is not the place for emotional language or threats beyond the legal action you're describing. Courts respond better to plaintiffs who approached the situation reasonably.
