What is a demand letter?
A demand letter is a formal written request for someone to do something. Usually to pay money owed, return property, or fix a breach before you take further action like small claims court. It states your claim clearly, sets a deadline, and signals you're serious, which often resolves the matter without a lawsuit.
An effective demand letter is firm but professional. It lays out the facts, states exactly what you want and by when, references the agreement or basis for the claim, and notes the consequence if the demand isn't met. Keeping it factual and specific, not emotional, makes it more persuasive and more useful if you do end up in court.
When do you need one?
Someone owes you money and hasn't paid
A landlord won't return your security deposit
Getting back personal property someone is holding
Collecting a real estate commission you earned
A breach of contract you want fixed or compensated
A final step before filing in small claims court
What it should include
Parties — who's demanding and who owes
The claim — exactly what you're owed or want done
The amount — the specific dollar amount, if money is owed
The basis — the facts and the agreement or law behind the claim
A deadline — a firm date by which to comply
The consequence — what you'll do if the demand isn't met (e.g., small claims)
Tone — firm and factual, not threatening or emotional
Signature — yours and the date, with proof of delivery
What makes a demand letter work
Demand letters resolve many disputes without court because they're specific, credible, and professional. Stick to facts, state a clear amount and deadline, reference your agreement, and keep the tone measured. Threats, insults, or exaggeration weaken your position and can even backfire if a judge sees the letter later.
A step before small claims
A demand letter is often the sensible last step before filing in small claims court — and some situations (like a security deposit) may require or benefit from one first. It gives the other side a clear chance to resolve it, and shows the court you acted reasonably.
Common mistakes to avoid
Being vague about the amount or what you want
An emotional or threatening tone that undermines your claim
No firm deadline to comply
Not stating the consequence (the credible next step)
Sending it with no proof of delivery
Exaggerating the claim, which hurts you if it reaches a judge
