Washington Small Business Breach of Contract Demand Letter

Most small business disputes in Washington reduce to one of three patterns: the customer did not pay, the vendor did not deliver, or the parties disagree about what the contract actually required. A well-drafted demand letter is often the cheapest way to test the other side's position and to build a record before filing. This guide walks through the legal framework I would use to draft one.

Quick answer

For most breach-of-contract disputes, a Washington demand letter is not statutorily required, but it is often useful. If the contract has a notice-and-cure clause, send it. If the contract has an attorney-fee clause, cite it. If a Washington statute conditions a remedy on prior written notice, follow the statute. And if the underlying conduct goes beyond ordinary breach into unfair or deceptive trade practice, the Consumer Protection Act under Chapter 19.86 RCW may add a per-se hook with treble damages capped at $25,000 and attorney fees under .

Written vs oral contracts under Washington law

Written contracts: six years

Under , an action upon a contract in writing, or upon a liability express or implied arising out of a written agreement, must be brought within six years. This is one of the longest written-contract limitations periods in the country and is twice as long as California's four-year period under California Code of Civil Procedure section 337. For Washington small businesses, that six-year window is real strategic value: a fully-papered deal preserves a long enforcement runway.

Oral contracts: three years

Under , several common claim types are limited to three years, including (1) waste or trespass upon real property, (2) taking or detaining or injuring personal property, (3) actions upon a contract or liability, express or implied, that is not in writing and not arising from a written instrument, (4) actions for fraud (with a discovery rule), (5) certain claims against sheriffs, coroners, and constables, and (6) actions to recover misappropriated public funds. The practical lesson: an oral agreement, a handshake deal, or a partially-papered arrangement is on a much shorter clock.

Mixed and ambiguous arrangements

Many real-world disputes are not cleanly "written" or "oral". They start with a signed proposal or statement of work, then drift into oral side agreements, text messages, and changed expectations. In Washington, the limitations question depends on whether the obligation at issue arises out of the written instrument. If the writing is fundamental, the six-year period under usually controls. If the writing is merely background and the disputed obligation is oral, the three-year period under may control. Demand letters should not over-claim the longer period without confirming which document actually governs the disputed obligation.

The four most common small business dispute patterns

Payment default (customer did not pay)

The classic accounts-receivable problem. The work was done, the invoice was issued, the customer went silent. The demand letter should attach the contract, attach the invoice, recite the dates and amounts, reference any late-fee clause or interest clause in the contract, and set a deadline. If the contract has an attorney-fee clause, cite it; this is the single most leverage-creating clause in a small business contract because it changes the cost calculus for the other side.

Services not delivered (vendor did not perform)

The mirror image: money paid, work not delivered or delivered defectively. The demand letter should identify the specific contractual deliverable, identify the deficiency (missed deadline, non-conforming work, abandonment), quantify damages (refund, cover costs, lost profit if proven with reasonable certainty), and demand a specific remedy (refund, completion, replacement, credit). If the contract has a cure period, the letter should give notice and demand cure.

Vendor and customer in scope dispute

Both sides agree something happened; they disagree about what was supposed to happen. These are the hardest matters because both sides are partially right. The demand letter is most useful here as a framing exercise: it forces both sides to commit to a written position, which often surfaces a settlement range that neither party would have offered orally.

Termination disputes

One side terminated; the other claims the termination was improper. The contract's termination clause governs. The demand letter should quote the clause, identify the trigger (or absence of trigger), and demand reinstatement or termination damages. A termination dispute under a contract with a notice-and-cure clause that was not followed is often a winnable matter; an at-will termination dispute where the contract permits termination on notice is usually not.

Notice and cure clauses

Many Washington small business contracts include a notice-and-cure clause: a party in breach must first receive written notice of the breach and a specified cure period (often 10, 15, or 30 days) before the non-breaching party may terminate or sue. If the contract has this clause, the demand letter is not optional, it is the procedural prerequisite to the remedy. A demand letter that does not properly invoke the notice-and-cure clause can be challenged later as defective notice, which is exactly the kind of defense an opposing party will raise on summary judgment.

Attorney fee clauses

Washington follows the American rule on attorney fees: each party generally bears its own fees unless a statute or contract provides otherwise. A contractual attorney-fee clause is the most common path to fee recovery. The clause must be reciprocal in effect under Washington law, so a one-sided fee clause favoring only the drafter is typically interpreted to apply mutually. The demand letter should cite the fee clause by section number, paragraph, and exact language.

Interest under Washington law

Pre-judgment interest is generally available in Washington on a liquidated claim (a sum certain or a sum calculable by reference to fixed standards in the contract) but not on an unliquidated claim. Post-judgment interest follows , which sets seven distinct categories rather than a single flat rate:

If the underlying contract specifies an interest rate, the demand letter should cite that rate and ask for pre-judgment interest to date.

When the Consumer Protection Act applies (and when it does not)

Ordinary breach of contract is not a CPA claim. The conduct must satisfy all five elements of Hangman Ridge: (1) an unfair or deceptive act, (2) in trade or commerce, (3) with public-interest impact, (4) causing injury to business or property, (5) caused by the conduct. Public-interest impact is the element most often disputed; it does not require statewide harm, but the conduct must have the capacity to affect more than the parties to the dispute, or there must be a pattern. The remedy under includes actual damages, reasonable attorney fees, and discretionary treble damages capped at $25,000 for violations of .

Examples that may rise to CPA: deceptive marketing of a business service, false certifications of qualifications, fraudulent invoicing, intentional misrepresentation of work performed, deceptive contract drafting that misleads a reasonable counterparty. Examples that usually do not rise to CPA: a customer who missed a payment deadline, a vendor who delivered late once, a good-faith scope disagreement, a contract dispute over price escalation.

When to hire an attorney

The Washington-specific legal work on these matters cannot be handled by me until Washington admission is complete. Until then, I can help with: California-side breach-of-contract matters where one or both parties are in California, federal-court contract matters, contract drafting and review of the underlying agreement, and educational triage on the strategic options. For Washington-only small business breach matters, my recommendation is to join the Washington availability list and to follow up after admission, or to work with a currently-admitted Washington attorney in the interim.
