Demand Letters 101: How to Write an Effective Legal Demand

A demand letter is often the most powerful tool in resolving disputes without going to court. According to the American Bar Association, negotiation and formal demands are the most common methods of resolving civil disputes. A well-crafted demand letter can recover money owed, resolve conflicts, and demonstrate you're serious about your legal rights - all without the expense and delay of litigation.

This guide covers what demand letters are, when to use them, essential elements to include, the right tone and style, how to send them properly, and what to do after sending.

Frequently Asked Questions

Do I need a lawyer to send a demand letter?

No. You can write and send a demand letter yourself. While attorney letterhead may carry additional weight, studies show that well-written letters from individuals are also effective. The key is being professional, specific, and accurate about the facts and law.

How long should I give them to respond?

A response deadline of 14-30 days is standard. For simpler matters like small debts, 10-14 days is reasonable. For more complex disputes or larger amounts, 30 days gives adequate time for the recipient to investigate and respond. Always specify an exact date, not just "14 days."

What if my demand letter is ignored?

If the recipient doesn't respond by your deadline, you should follow through with the consequences you stated—typically filing in small claims court or reporting to relevant agencies. An ignored demand letter becomes evidence of the recipient's unwillingness to resolve the dispute, which courts view unfavorably.

Can a demand letter hurt my case?

Only if you include false statements, make threats you can't or won't follow through on, or use inappropriate language. Keep your letter factual, professional, and accurate. Everything in your demand letter can be used as evidence, so it should strengthen—not weaken—your position.
