A demand letter is a formal request for payment or action before you escalate to court. To write one, you state the facts, identify what you are owed, set a deadline, and send it with proof of delivery. Keep it factual and dated. You can draft it yourself, but have a lawyer review it before sending if the amount is significant or the facts are disputed. The steps below follow the order you actually work in, not the order the sections appear on the page.
If you want a starting structure, the Demand Letter tool on this site lays out the sections and lets you fill them in without uploading your facts to a server.
Step 1: Decide what the letter has to accomplish
A demand letter does two jobs. It asks the other side to pay or act, and it creates a record that you tried to resolve the dispute before filing. Decide which job matters more to you before you write a word. If you plan to sue, the letter should be precise enough to attach as an exhibit later. If you only want the money, a shorter letter that is easy to answer may work better.
Write one sentence that states what you want: a specific amount, the return of property, or a specific action. If you cannot state it in one sentence, you are not ready to write the letter. Break the problem into separate demands and decide which one you will pursue first.
Step 2: Build the fact timeline from documents, not memory
Pull the contract, invoices, emails, text messages, delivery receipts, and bank records. Put them in date order. For each event, write the date, what happened, and which document proves it. Use only facts you can point to a document for. If a phone call matters, write down the date, who said what, and whether anyone else was on the line.
This timeline becomes the body of the letter. It also tells you whether your demand is solid. If the other side can point to a document that contradicts your timeline, you need to know that before you send anything.
Step 3: Set the amount and the deadline with a formula
The amount should be the sum of the principal plus any interest or fees your agreement allows. Do not round up and do not add amounts you cannot support. If you are charging interest, state the rate and the period it covers. If you are not sure what the contract allows, leave interest out and say so.
The deadline should be a specific calendar date, not “within 30 days.” Pick a date at least ten business days out so the other side has time to respond, and check that it does not fall on a weekend or a holiday. State what happens if the deadline passes: you will file in a named court or pursue the next step. Do not threaten criminal charges or actions you cannot take.
Step 4: Format the letter so it can be read quickly
Use a standard business letter layout. Put your name and address at the top, the date, the recipient’s name and address, a subject line, and then the body. Number your paragraphs so the other side can respond to each point. Keep paragraphs short and avoid adjectives.
Sign the letter and keep a copy. If you are sending on behalf of a business, use the business letterhead and state your role.
Step 5: Choose delivery and keep proof
Send the letter by a method that gives you a receipt. Keep the receipt and a copy of the letter. If you send by email, use a read receipt and save the sent message. If you send by certified mail, keep the tracking number and the delivery confirmation. The proof matters more than the method. If the other side claims they never received the letter, your receipt is the answer.
What breaks in a demand letter
The table below lists the common failure points and what to check before you send. It is not legal advice.
| Problem | What it looks like | What to check |
|---|---|---|
| Wrong amount | Total does not match invoices plus allowed interest | Re-add each line from the documents |
| Vague deadline | “Soon” or “within a reasonable time” | Replace with a specific date |
| Missing proof | No delivery receipt or copy of the letter | Keep tracking number and a signed copy |
| Emotional language | Accusations or threats | Remove adjectives; state facts only |
| Wrong recipient | Letter sent to a person who cannot authorize payment | Check the contract for the notice address |
| No next step | Letter demands payment but says nothing about what follows | State the next step you will take, without overpromising |
When this does not apply
Do not use this workflow if the dispute involves a lease clause you do not understand, a contract with an arbitration clause that requires a different notice, or a claim that may be barred by a statute of limitations. Do not send a demand letter if you are not prepared to follow through with the next step. If the amount is large, the facts are disputed, or the other side has a lawyer, have a lawyer review the letter before it goes out. This article does not interpret your contract and does not tell you whether your demand is enforceable.
The point where a lawyer still has to look at it
A lawyer should review the letter before you send it when the demand is over the small claims limit in your jurisdiction, when the other side is represented, when the contract has a notice or arbitration clause, or when you are not sure which court would hear the case. The review is not about making the letter sound tougher. It is about confirming that the demand matches what the contract and the law allow, and that the deadline and next step do not create a problem for you later.
If you are drafting the letter yourself to save time, keep the language plain and attach the documents you rely on. If you need a structured starting point, the Demand Letter tool is one option. If you are also dealing with a contract or lease, use the Lease Clause Check to identify clauses you should ask about, not to get a legal opinion.
FAQ
How long should a demand letter be?
One to three pages is typical. Long enough to state the facts and the demand, short enough that the reader can find the amount and the deadline without hunting.
Do I have to send a demand letter before suing?
Not always. Some contracts require a notice before filing, and some courts expect you to show you tried to resolve the dispute. Check your contract and your local court rules.
Can I send a demand letter by email?
Yes, if you can prove it was sent and received. Save the sent message and any read receipt. If the contract specifies a notice method, use that method.
What should I do if the other side ignores the letter?
Decide your next step before the deadline passes. That may mean filing in court, using a mediation service, or sending a second letter. Do not send a threat you are not prepared to carry out.
