A Demand Letter for Breach of Contract is a formal written notice sent by an aggrieved party (or their attorney) to a party who has failed to fulfill their contractual obligations. It identifies the specific contract provisions that were breached, demands a remedy (typically performance or monetary damages), and establishes a deadline for compliance before legal action is initiated. The letter serves as both a final attempt at resolution and a prerequisite to litigation in many jurisdictions.

Breach of contract claims are governed by state contract law, with the Restatement (Second) of Contracts providing the analytical framework used by most courts. Under Restatement Section 235, a breach occurs when a party fails to perform a duty that has become due under the contract. The severity of the breach determines the available remedies: a material breach (Section 241) excuses the non-breaching party from further performance and entitles them to damages, while a minor breach entitles the non-breaching party to damages but does not discharge their own obligations.

Many contracts contain provisions requiring written notice of breach and an opportunity to cure before legal action can be filed. Courts in numerous jurisdictions have held that failure to send a demand letter or notice of breach before filing suit can result in dismissal for failure to exhaust pre-litigation remedies. Even where not contractually required, a demand letter demonstrates good faith, establishes the factual record, and often resolves disputes without the time and expense of litigation. Studies indicate that approximately 30-50% of breach of contract disputes are resolved after a demand letter is sent.

A Breach of Contract Demand Letter is needed in these situations: when a contractor fails to complete construction work as specified in the contract; when a client refuses to pay for services that were delivered according to the agreement; when a vendor delivers defective goods or fails to meet delivery deadlines specified in a purchase order; when a tenant violates lease terms such as unauthorized subletting, property damage, or non-payment of rent; when a business partner fails to make required capital contributions or fulfill their duties under a partnership agreement; and when a software vendor fails to deliver a product that meets the specifications outlined in a development agreement.

Additional scenarios include breach of non-compete or non-solicitation agreements by former employees, failure to comply with settlement agreement terms, breach of franchise agreement provisions, and violation of licensing agreement terms including unauthorized use of intellectual property.

Sending the demand letter before filing suit serves multiple strategic purposes. It satisfies any contractual notice and cure requirements. It creates a documented record of the breach and the demanded remedy. It may trigger insurance coverage obligations for the breaching party. And it demonstrates to a future court that the plaintiff acted reasonably and attempted to resolve the matter before resorting to litigation, which can affect the award of attorney's fees in jurisdictions that consider pre-litigation conduct.

An effective Breach of Contract Demand Letter must include the following elements:

Sender and recipient identification -- the full legal names and addresses of both parties, matching the names on the original contract.

Contract identification -- the specific contract that was breached, identified by title, date, parties, and contract number. Attach a copy of the relevant contract or reference the specific sections that were violated.

Factual description of the breach -- a clear, chronological recitation of the facts constituting the breach, including specific dates, actions (or failures to act), and the contract provisions that were violated. Avoid emotional language and focus on objective facts.

Damages suffered -- a detailed accounting of the damages resulting from the breach, including direct damages (the cost to complete or correct the work), consequential damages (lost profits, additional expenses incurred), and incidental damages (costs incurred in attempting to mitigate). Where applicable, reference the contract's liquidated damages provision.

Demand for remedy -- a specific statement of what the sender demands: full performance of the contract, monetary payment of a stated amount, return of property, or other specific relief. The demand should be reasonable and directly related to the breach.

Deadline for response -- a reasonable deadline for the recipient to respond or comply, typically 10-30 days. The deadline should be a specific calendar date, not a relative timeframe.

Consequences of non-compliance -- a clear statement that if the demand is not met by the deadline, the sender intends to pursue legal remedies, which may include filing a lawsuit, seeking injunctive relief, and recovering attorney's fees and court costs where authorized by the contract or statute.

Preservation of rights -- a statement that the letter does not constitute a waiver of any rights or remedies available under the contract or applicable law.

Delivery method -- the letter should be sent via certified mail with return receipt requested, providing proof that the recipient received the notice.
