What Should a Breach of Contract Demand Letter Include?

A good breach of contract demand letter does four things: it identifies the contract terms the other side broke, explains the harm in numbers, tells the recipient exactly what you want and by when, and protects your position if the dispute ends up in court. It should be firm without overstating your case, because the letter will likely become an exhibit. Before you send one, check your contract’s notice clause. Many business agreements require written notice to a specific person or address, and some give the breaching party a cure period before you can terminate or sue. A letter that ignores those terms can delay your remedies or hand the other side a defense.

When a demand is the first move in a larger dispute, our commercial litigation and dispute resolution team drafts it with the next step already in mind.

Check the contract before you write

Read three provisions first.

Notice clause

It usually says how notice must be delivered (certified mail, courier, or email to a named address) and to whom. Follow it exactly, and consider sending by more than one method so delivery is never in doubt.

Cure period

If the contract gives the other party time to fix a breach after notice, your letter starts that clock. Say clearly that the letter is the notice of breach under the relevant section, and calendar the deadline.

Dispute resolution clause

Some contracts require negotiation between executives, mediation, or arbitration before or instead of a lawsuit. Others set the governing law and the court where suits must be filed. Your demand should follow that path. Our post on mediation versus arbitration for business disputes explains how those clauses work.

Also check for an attorney’s fees provision. Under the American rule, each side pays its own lawyers unless a contract or statute says otherwise, so a fee clause can change both sides’ math. If these terms are missing or unclear, it is worth fixing your templates afterward with our contract drafting and negotiation attorneys.

What to put in a breach of contract demand letter

A clear structure works best:

1. The parties and the agreement, by name and date, with the specific sections at issue.
2. A short factual account of what was promised and what happened. Stick to facts you can document, and reference the invoices, delivery records, emails, or acceptance forms that prove them.
3. The breach, tied to contract language. A sentence like “Section 4.2 required delivery by March 1, and no shipment arrived until April 15” is far stronger than “you failed to perform.”
4. Your damages, with the calculation shown. Separate amounts that are certain, such as an unpaid invoice, from amounts you are still assessing, such as lost business.
5. The demand itself: payment, performance, a corrected deliverable, or a meeting to resolve the issue, with a reasonable deadline.
6. A reservation of rights, stating that the letter does not waive any claims or remedies.
7. A request that the recipient preserve documents and electronic records related to the dispute.

What to leave out

Overstatement hurts you later. Do not claim damages you cannot support, accuse the other side of fraud without a basis, or threaten criminal charges to pressure a payment; ethics rules in many jurisdictions restrict lawyers from that tactic, and it can expose the sender to liability. Avoid admissions about your own performance problems.

If you want to propose a compromise number, consider doing it in a separate settlement communication. Federal Rule of Evidence 408 and similar state rules generally keep settlement offers out of evidence when offered to prove liability or the amount of a claim, but they do not shield underlying facts just because those facts appear in a settlement letter.

Watch the limitation period

A demand letter does not stop the statute of limitations. If the deadline to sue is close, you may need to file first and negotiate after. In the firm’s jurisdictions, the general periods for breach of contract are:

• Virginia: five years for a written contract and three years for an unwritten one.
• Washington, DC: three years.
• New York: six years.

Contracts for the sale of goods generally fall under the Uniform Commercial Code’s four-year period, and some contracts shorten the time to bring claims. When the clock starts can also be disputed. Treat these numbers as a starting point and confirm the rule for your specific agreement.

What happens after you send it

Most recipients respond in one of four ways: they pay or perform, they propose a negotiation, they dispute the claim with their own version of events, or they ignore the letter. Each response tells you something. A detailed denial previews their defenses. Silence past the deadline is your cue to decide whether to file, start the contract’s dispute process, or reassess.

Before you escalate, get your own house in order. Put a litigation hold in place for your team, gather the documents that prove performance and damages, and confirm who at your company can speak to the facts. Our earlier overview of the business litigation process walks through what follows if the dispute goes to court.

Sometimes the letter is the wrong first step. If the relationship has value, a call between decision-makers may resolve the issue faster, with the letter held in reserve. If the other side may move assets or destroy evidence, counsel may advise going straight to court.
