A breach of contract demand letter is the standard first step when someone fails to hold up their end of an agreement. It identifies the contract, pinpoints which terms were broken, and demands a specific remedy — performance, correction, or monetary damages — with a firm deadline.
This page shows a complete, annotated example and explains what each section does. You can also use the free breach of contract demand letter generator to build a customized version for your situation in a few minutes.
What makes a breach of contract demand letter effective
An effective letter does three things:
- Identifies the contract clearly — date, parties, and what each side agreed to do
- Pinpoints the exact breach — which term was violated and how
- Demands a specific remedy with a deadline — performance, correction, or a dollar amount
Vague letters get vague responses. A letter that quotes the contract, shows your damages, and names small claims court as the next step creates the pressure needed to get results.

RE: NOTICE OF BREACH AND DEMAND TO CURE — Web Design Agreement dated March 1, 2026
Dear Mr. Reyes,
[Opening — identify the contract clearly]
This letter concerns the Web Design Agreement (the “Agreement”) entered into between Jane Doe and Apex Web Solutions LLC on March 1, 2026. Under the Agreement, Apex agreed to design and deliver a complete five-page business website, including a contact form and e-commerce checkout, for a total price of $4,500, with delivery no later than May 15, 2026.
[Your performance — confirm you held up your end]
I have fully performed my obligations under the Agreement. I paid a 50% deposit of $2,250 on March 1, 2026, in accordance with the payment schedule. I provided all required content, brand assets, and written approvals on March 18, 2026 — well ahead of your stated deadline.
[The breach — be specific, quote contract terms if possible]
You have materially breached the Agreement. As of the date of this letter — more than three weeks past the May 15 delivery date — no completed website has been delivered. I have sent four written requests for a status update on May 16, May 20, May 27, and June 4, 2026, all of which went unanswered. Under Section 4 of the Agreement, time of delivery was stated to be of the essence.
[Your damages — calculate and state clearly]
As a result of your breach, I have suffered damages of $2,250, representing the deposit I paid for services not delivered. I have also incurred $350 in costs obtaining a temporary website solution while I seek a replacement developer. My total documented damages are $2,600.
[The demand — specific remedy and firm deadline]
I demand that you either (1) deliver the completed website as specified in the Agreement by June 24, 2026, or (2) refund the $2,250 deposit by that date.
[Consequence — what happens if they miss the deadline]
If you fail to deliver the website or refund the deposit by June 24, 2026, I will pursue all remedies available to me under Illinois law and the Agreement, including filing a claim in Cook County Small Claims Court for $2,600 in damages, plus court costs and any interest allowed by law.
[Closing — professional, not threatening]
I would prefer to resolve this matter promptly without court involvement. Please contact me at (312) 555-0192 or jane.doe@email.com to confirm your intended course of action.
Sincerely,
Jane Doe
What this example gets right
Quoted the contract date and scope. The letter opens with the exact agreement — date, parties, what was promised, and the price. No room for the other side to claim there was no contract.
Confirmed her own performance. A common defense is “you breached first” or “you didn’t give us what we needed.” The letter preempts this by documenting her deposit payment and the timely delivery of content.
Named a specific section. “Section 4 — time of delivery was of the essence” tells the reader the sender has actually read the contract. It raises the stakes.
Documented prior attempts. Four dated follow-up requests shows the sender gave the other party a genuine chance to respond. Courts see this favorably.
Itemized damages. The $2,250 deposit plus $350 in mitigation costs, totaling $2,600, is specific and defensible. Vague damages lose in court.
Offered two remedies. Performance (deliver the site) or a refund. This is reasonable and shows flexibility while maintaining a firm position.
Named the specific court. “Cook County Small Claims Court” tells the recipient exactly what filing looks like. It is not a hypothetical threat — it is a specific, imminent step.
Key elements to include in your letter
| Element | What to write |
|---|---|
| Contract identification | Date, parties, subject matter |
| Your performance | What you did to hold up your end |
| The breach | Specific term violated, with date |
| Damages | Exact dollar amount with calculation |
| Remedy demanded | Performance, repair, or specific refund |
| Deadline | Specific calendar date (10–14 days) |
| Consequence | Small claims court, lawsuit, or both |
What to do if the contract is verbal
Oral contracts are enforceable in most situations (with some exceptions for large real-estate deals and multi-year agreements). Without a written contract, gather:
- Emails or texts where both parties agreed to the terms
- Invoices or quotes that were accepted
- Payment records (bank transfers, checks, receipts)
- Any written proposals or estimates
Reference these in your letter: “Under our oral agreement confirmed in your email of March 1, 2026…”
Notice-to-cure clauses
Many written contracts contain a “notice to cure” provision — a requirement that you give the breaching party a written notice and a specific number of days to fix the problem before you can sue. If your contract has one, your demand letter is the notice to cure. Make sure the deadline you set matches or exceeds the contractual cure period.
Check Section headings like “Default,” “Breach,” “Termination,” or “Dispute Resolution” in your contract.
After you send the letter
If they comply: Get their response in writing. If they deliver the work or issue the refund, confirm in a brief email and keep a record.
If they offer a partial remedy: Evaluate it carefully. Accepting a partial refund and signing anything may release your other claims. Get any settlement in writing.
If they ignore the deadline: File in small claims court. Your demand letter, the contract, proof of your performance, and the certified mail return receipt are your core evidence.
Most small claims courts allow claims up to $10,000–$25,000 depending on the state. Filing fees are typically $30–$100. You do not need a lawyer.
