A demand letter is often the first step to settling a dispute, and sometimes the only one needed. It states your claim, says what you want, and sets a deadline to respond. A clear letter signals you're serious about your rights before going to court. This is legal information, not legal advice.
Walk through what happened in plain, factual language. Skip the emotion and threats. Include dates, dollar amounts, and the specific details that back your claim.
Name it: a refund, a payment, a repair, a specific action. Vague demands get ignored. If money is involved, state the exact dollar amount.
Give 10 to 30 days to respond. A deadline creates urgency and shows you expect action. It also sets a clear timeline if you later escalate to court.
Reference the law, contract clause, or principle behind your claim. You don't need to cite case law, just show the demand stands on a legal footing.
Certified mail with return receipt proves the recipient got the letter. That proof can matter as evidence if the dispute reaches court.
