A breach of contract in Washington State happens when one party fails to perform a valid agreement without a legal excuse, and the other party suffers measurable loss as a result. The injured party generally has six years to sue on a written contract and three on an oral one, and Washington courts can award money damages, enforce a liquidated damages clause, or in narrow cases order the breaching party to perform. Punitive damages are not available.
What You Have to Prove
Washington courts use a four-part test. You must show a valid contract existed, you performed your side of the bargain, the other party failed to perform without a legally recognized excuse, and that failure caused your losses.1New York Codes, Rules and Regulations. Washington Pattern Jury Instructions – Civil WPI 300.02 – Burden of Proof on the Issues – Breach of Contract – No Affirmative Defense A valid contract needs mutual agreement, consideration on both sides, and terms specific enough that a court can tell whether someone broke them.
Not every failure counts the same. A material breach goes to the core of what the parties bargained for and can excuse the other side from performing at all. A minor shortfall does not. Under the doctrine of substantial performance, a party who completes the important parts of a contract can still recover payment even when some details fall short. This matters most in construction disputes where a contractor finishes nearly all the work but leaves punch-list items.
Contracts for the sale of goods are judged more strictly. Under RCW 62A.2-601, if delivered goods fail in any respect to match the contract, the buyer may reject the whole shipment, accept all of it, or accept some units and reject the rest.2Washington State Legislature. RCW 62A.2-601 – Buyers Rights on Improper Delivery That “perfect tender” rule is less forgiving than the substantial performance standard used for service contracts.
How Long You Have to Sue
Washington gives you six years to file suit on a breach of a written contract, counted from the date of the breach rather than the date of signing.3Washington State Legislature. RCW 4.16.040 – Actions Limited to Six Years Oral contracts get three years under RCW 4.16.080. Miss either deadline and the court will almost certainly dismiss the case regardless of its merits.
The clock can pause in limited circumstances. If the breaching party actively concealed the breach, Washington courts may not start counting until you discovered or reasonably should have discovered what happened. That discovery rule usually surfaces in professional malpractice and deliberate concealment cases. If you suspect a contract has been broken, do not wait and hope the other side comes around.
What You Can Recover
Contract damages in Washington aim to put the injured party in the financial position they would have been in if the contract had been performed. Courts call this the expectation interest, and it drives most calculations.4New York Codes, Rules and Regulations. WPI 303.01 Measure of Expectation Damages – Breach of Contract – No Counterclaim
Compensatory and Consequential Damages
Compensatory damages cover the direct gap between what you were promised and what you received. If a contractor agreed to finish a remodel for $50,000 and walked off, your compensatory damages would be the cost of hiring a replacement minus whatever you had not yet paid.
Consequential damages reach further, covering indirect losses like lost revenue from a delayed storefront opening. The limit is foreseeability. You can only recover losses both parties reasonably anticipated when they signed. If the breaching party had no way to know your particular circumstances would produce those losses, the claim will fail, and the damages still have to be proven with reasonable certainty rather than speculation.
Liquidated Damages
Some contracts set the penalty amount in advance through a liquidated damages clause. Washington courts enforce these clauses when the agreed figure was a reasonable estimate of potential harm at the time of signing. If the number looks more like a punishment than a forecast, the court will strike it as an unenforceable penalty.
Specific Performance
When money cannot make the plaintiff whole, Washington courts can order the breaching party to actually do what they promised. This remedy appears most often in real estate deals and contracts for unique property. Under the UCC, specific performance is available when goods are unique or in other proper circumstances.5Washington State Legislature. RCW 62A.2-716 – Buyers Right to Specific Performance or Replevin Courts grant it sparingly because forcing performance raises practical enforcement problems a money judgment does not.
Prejudgment and Post-Judgment Interest
Washington’s default interest rate on unpaid contract obligations is 12 percent per year when the contract itself does not specify a different rate.6Washington State Legislature. RCW 19.52.010 – Rate of Interest Once a court enters judgment, the calculation can change. Judgments on written contracts without an agreed rate bear interest at the maximum rate allowed under RCW 19.52.020, while other judgments use a variable rate tied to Treasury bill yields.7Washington State Legislature. RCW 4.56.110 – Interest on Judgments
No Punitive Damages
Washington does not award punitive damages in breach of contract cases. Recovery is limited to actual, provable losses. No amount of bad behavior by the breaching party changes that in a pure contract dispute. If the same conduct also involves fraud or another independent tort, punitives might come in through that separate claim, but not through the contract claim itself.
Attorney Fees
Washington follows the American Rule, so each side normally pays its own attorney fees regardless of who wins. Two exceptions matter. If the contract has a prevailing-party fee provision, the court will enforce it. And when the amount in controversy is $10,000 or less, the prevailing party can recover reasonable attorney fees as costs under RCW 4.84.250.8Washington State Legislature. RCW 4.84.250 – Attorneys Fees as Costs in Damage Actions of Ten Thousand Dollars or Less Check the contract for a fee-shifting clause before deciding whether litigation makes financial sense.
Your Duty to Mitigate
Washington requires the non-breaching party to take reasonable steps to limit losses after a breach. You cannot sit idle, let damages pile up, and then hand the full bill to the other side. If a tenant breaks a commercial lease, the landlord has to make reasonable efforts to find a replacement rather than leaving the space empty and suing for all the remaining rent.
The standard is reasonableness, not perfection. A good-faith effort that falls short will not be punished, and the costs of trying to mitigate are themselves recoverable as damages. The burden of proving failure to mitigate falls on the defendant, who must show what steps you should have taken, that those steps would have reduced the harm, and by how much. Failure to mitigate does not kill a claim; it reduces the award by the amount the court finds could have been avoided.
Acting Before the Deadline: Anticipatory Repudiation
You do not always have to wait for the performance date to pass. If the other party clearly and unconditionally communicates that they will not perform, Washington treats that as an anticipatory breach. The refusal does not need to be written; actions that make performance impossible count too, such as selling the property you agreed to buy to someone else.
The refusal has to be definitive. Vague complaints or hedging (“I’m not sure we can deliver”) usually will not qualify. For goods contracts under the UCC, a party with reasonable grounds for insecurity can demand written assurance of performance and suspend its own performance until the assurance arrives.
Defenses the Other Side May Raise
Not every broken promise produces liability. Washington recognizes several defenses that can defeat or shrink a claim.
Statute of Frauds
Certain contracts must be in writing. Washington’s statute of frauds covers agreements for the sale of real property, contracts that cannot be completed within one year, promises to guarantee someone else’s debt, and contracts for the sale of goods worth $500 or more under the UCC. If your agreement falls into one of these categories and was only verbal, a court will likely refuse to enforce it.
Impossibility, Impracticability, and Frustration of Purpose
A party may be excused when something genuinely unforeseeable makes performance impossible or impracticable. The event cannot be the party’s own doing, and the contract must not have assigned that risk. A warehouse destroyed by wildfire might qualify. A business that simply ran out of money will not. Market downturns and financial difficulty are not enough on their own.
Frustration of purpose is related but distinct. It applies when both sides can still technically perform, but an unexpected event has destroyed the entire reason for the deal. The classic example is renting a room to watch a parade that gets canceled.
Failure of Consideration and Prior Breach
If the plaintiff never delivered the value they promised, the defendant can argue failure of consideration. And if the plaintiff breached first, that prior breach may excuse the defendant’s nonperformance. Washington courts will not let a party already in default collect damages against the other side for the same failure.
Before You File
Read the contract first. Many commercial agreements require mediation, arbitration, or both before anyone files suit. A mandatory arbitration clause moves the dispute to a private forum with limited discovery and almost no right to appeal. Filing in court when the contract requires arbitration wastes time and money because the case will likely be dismissed and routed to arbitration anyway. Raise an arbitration clause early; parties who engage too far in litigation before invoking it can waive the right.
Documentation is what wins contract cases. Pull together the contract itself, any amendments, emails, texts, invoices, delivery receipts, and any correspondence about the parties’ obligations. Build a timeline showing when each side performed or failed to. Keep a log of post-dispute interactions, including call dates and summaries, because partial payments, offers to cure, or admissions of fault can be decisive at trial.
Send a formal demand letter before suing. Identify the specific provision that was broken, describe the harm, state the dollar amount you want, and set a deadline for response, typically 14 to 30 days. Certified mail gives you proof of delivery. A well-drafted demand letter shows good faith if the case goes to court and sometimes produces a settlement on its own.
Filing a Lawsuit
Where you file depends on how much is at stake. Washington’s small claims courts handle disputes up to $10,000 for individuals and $5,000 for businesses and other non-natural persons.9Washington State Office of the Attorney General. Small Claims Court Small claims is designed to work without an attorney, with filing fees of $35 or $50 depending on the county.10Washington State Courts. Small Claims Court – Section: How Much Does It Cost Larger disputes go to Superior Court, where filing fees run from roughly $36 to $320.11Washington Law Help. Ask the Court for a Fee Waiver
Serving the Defendant
After filing the Summons and Complaint, you must formally deliver copies to the defendant. Washington law requires a third party, not you, to hand-deliver the documents.12Washington State Legislature. RCW 4.28.080 – Summons, How Served A professional process server typically runs $50 to $100 per attempt; the county sheriff is another option. For a business, the papers must go to a registered agent or officer listed in the state’s business registry. Sloppy service can derail the whole case.
The Defendant’s Response
Once served, the defendant has 20 days to file a written response in Superior Court.13Washington Courts. CR 12 – Defenses and Objections If no answer arrives within that window, you can ask the court for a default judgment, which grants your requested damages without a trial. Most contract disputes settle before trial, but keeping your documentation organized from the start strengthens your position whether negotiations happen at a settlement table or in front of a judge.
