How to write a demand letter (free template + 7-step guide)

What a demand letter actually is

A demand letter is a formal written request that the recipient pay money or perform some specific action by a stated deadline. It is the last off-ramp before a lawsuit. The recipient sees that you are organized, willing to take the next step, and serious about the timeline.

Done well, a demand letter resolves the matter without a single court filing. Done poorly, it creates evidence that hurts you later. The difference is structure and tone.

The 7 essential elements

1. Your full name and address at the top, then today's date.

2. Recipient name and address.

3. A clear "Re:" line that names the matter in one sentence.

4. A factual paragraph: what happened, when, who was involved. Stick to facts you can prove.

5. A legal-basis paragraph: the contract clause, statute, or common-law doctrine that gives you the right to demand. Plain language is fine: "Section 4 of our lease dated [date]" or "California Civil Code Section 1942."

6. The demand itself: be specific. Dollar amount, action, or both. Vague demands ("make this right") read as theatrics.

7. The deadline: typically 14 to 30 days. State the exact consequence of missing it (file suit, report to a regulator, record a lien).

Tone is the entire game

A demand letter is not a place to vent. The reader will look for emotion to dismiss the letter as a bluff. Stay clinical. State facts in numbered paragraphs. Reserve all rights at the end.

Read it out loud before sending. If any sentence sounds like it could appear on the local news as a quote you would regret, cut it.

What to do when the deadline passes

If the deadline passes without resolution, your options scale with the dollar amount and your jurisdiction. Small claims courts handle disputes up to $5,000 to $25,000 depending on state. Above that, you typically need an attorney.

Either way, do exactly what your letter said you would do. The single biggest credibility leak is making a threat and not following through.

Frequently asked questions

Do I need a lawyer to send a demand letter?

No. Demand letters are routinely sent by individuals and small businesses without an attorney. That said, when the dispute exceeds small-claims limits or involves complex damages, an attorney drastically increases your leverage.

How long should a demand letter be?

One to two pages. The recipient should be able to read the entire letter in two minutes and immediately understand the demand, the basis, and the deadline.

Should I send by certified mail?

Yes. Certified mail with return receipt is the standard for proving receipt. Email is also acceptable as a backup when you have an established email channel with the recipient.
