A breach of contract in Washington state gives the injured party up to six years to sue on a written agreement, three years on an oral one, and a choice of remedies that runs from money damages to a court order compelling the other side to perform. To win, you have to prove four things and, once the breach happens, take reasonable steps to limit your own losses. The rules shift depending on whether the deal involved goods or services, whether it was written down, and how much money is on the line.
What You Have to Prove
Washington courts use a four-part framework. 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 financial harm.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 definite enough for a court to measure performance against.
Not every failure counts equally. 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 slip does not. Under the doctrine of substantial performance, a party who completed the essential parts of a contract can still recover payment even if some details fell short. Construction disputes turn on this often: a contractor who finishes 95 percent of a remodel but leaves punch-list items outstanding is usually still entitled to payment, minus the cost to complete.
Contracts for the sale of goods play by a stricter rule. Under RCW 62A.2-601, if delivered goods fail in any respect to conform to the contract, the buyer can reject the whole shipment, accept it all, or accept some units and reject the rest.2Washington State Legislature. RCW 62A.2-601 – Buyers Rights on Improper Delivery This “perfect tender” rule is far less forgiving than the substantial performance standard that governs service contracts.
How Long You Have to File
Washington gives you six years to file suit on a written contract, measured from the date of the breach rather than the date you signed.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 the underlying merits.
The clock can pause in narrow situations. If the breaching party actively concealed the breach through fraud or deception, Washington courts may not start counting until you discovered, or reasonably should have discovered, what happened. That discovery rule shows up most often in professional malpractice or deliberate concealment cases. If you suspect a breach, do not wait it out hoping the other side will make things right on their own.
What You Can Recover
The goal of contract damages in Washington is to put you where you would have been if the contract had been performed. Courts call this the expectation interest, and it drives most damage 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 got. If a contractor agreed to complete a remodel for $50,000 and walked off, your compensatory damages include the cost of hiring someone else to finish, minus what you had not yet paid.
Consequential damages reach further, covering indirect losses that flow from the breach, such as lost business revenue from a delayed storefront opening. There is a catch: you can only recover consequential damages both parties reasonably anticipated when they signed. If the breaching party had no way to know your particular circumstances would produce those losses, that piece of the claim fails. Proving these damages usually takes detailed financial records and sometimes forensic accounting, because speculation will not carry the day.
Liquidated Damages
Some contracts fix the amount owed for a breach up front. Washington courts enforce liquidated damages clauses when the agreed figure was a reasonable estimate of potential harm at the time of signing. If the number looks more like a penalty than a forecast, the court will throw it out.
Specific Performance
When money cannot make you whole, a Washington court can order the breaching party to actually do what they promised. This remedy is most common in real estate deals and disputes over unique property. Under the UCC, specific performance may be ordered where 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 creates enforcement headaches that a money judgment avoids.
Interest
Washington’s default interest rate on unpaid contract obligations is 12 percent per year when the contract itself does not set a different rate.6Washington State Legislature. RCW 19.52.010 – Rate of Interest Once judgment is entered, the calculation may shift. Judgments on written contracts without an agreed rate bear interest at the maximum permitted under RCW 19.52.020; other judgments use a variable rate tied to Treasury bill yields.7Washington State Legislature. RCW 4.56.110 – Interest on Judgments
What You Cannot Get: Punitive Damages
Washington does not award punitive damages in breach of contract cases. Recovery is limited to actual, provable losses, and no amount of bad conduct by the breaching party changes that in a pure contract dispute. If the same facts also support a fraud or other tort claim, punitive damages might enter through that separate claim, never through the contract itself.
Attorney Fees
Washington follows the American Rule: each side pays its own attorney fees unless something else applies. Two exceptions matter. If the contract has a prevailing-party fee provision, courts enforce it. And for cases where the amount at stake 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 the numbers justify a lawsuit.
What Can Defeat Your Claim
Several defenses can knock out or reduce a breach of contract case in Washington.
Statute of Frauds
Some contracts have to be in writing to be enforceable. Washington’s statute of frauds covers agreements for the sale of real property, contracts that cannot be completed within one year, promises to guarantee another person’s debt, and contracts for the sale of goods worth $500 or more under the UCC. If your agreement fits one of those categories and was never written down, a court will likely refuse to enforce it no matter what was said out loud.
Impossibility, Impracticability, and Frustration of Purpose
A party may be excused from performing when something genuinely unforeseeable made performance impossible or impracticable. The event cannot be the party’s own fault, and the contract must not have already assigned that risk. A warehouse destroyed by wildfire might qualify. A business that simply ran out of money will not. Market downturns and financial hardship, on their own, are not enough. Frustration of purpose is a related defense: both parties can still technically perform, but an unexpected event has destroyed the shared reason the contract existed in the first place.
Prior Breach and Failure of Consideration
If you never actually delivered the value you promised, the defendant can raise failure of consideration. If you breached first, that prior breach may excuse the defendant’s later nonperformance. Washington courts will not let a party who is already in default collect against the other side for the same failure.
Your Duty to Mitigate
Washington requires the non-breaching party to take reasonable steps to limit losses after a breach. You cannot sit still, let damages accumulate, and then hand the full bill to the other side. If a tenant walks out of a commercial lease, the landlord has to make reasonable efforts to re-let the space instead of leaving it empty and suing for every remaining month.
The standard is reasonableness, not perfection. A good-faith effort that does not pan out will not be held against you, and the costs of the mitigation effort itself are recoverable as part of your damages. The burden of proving failure to mitigate falls on the defendant, who has to show what steps you should have taken, that they would have worked, and by how much they would have cut the loss. A finding that you failed to mitigate does not kill the case; it reduces the award by what the court believes you could have avoided.
Suing Before the Deadline: Anticipatory Repudiation
You do not always have to wait until the performance date passes. If the other party clearly and unconditionally communicates that they will not perform, Washington treats that as an anticipatory breach. The refusal does not have to be in writing; actions that make performance impossible count too, like selling to a third party the property you had agreed to buy.
The signal has to be definitive. Vague complaints or hedging like “I’m not sure we can deliver” typically do not qualify. For goods contracts under the UCC, a party with reasonable grounds for insecurity can demand written assurance of performance and suspend their own performance until it arrives.
Before You File: Arbitration, Documents, Demand
Read the contract for a dispute resolution clause first. Many commercial contracts require mediation, arbitration, or both before anyone can file a lawsuit. A mandatory arbitration clause moves the fight to a private forum with different rules, limited discovery, and almost no appellate review. Filing in court when the contract requires arbitration usually leads to dismissal and a detour to arbitration anyway. If there is an arbitration clause, raise it early; parties who litigate too far before invoking arbitration risk waiving the right.
Documentation wins contract cases. Pull together the contract itself, every amendment, emails, text messages, invoices, delivery receipts, and any correspondence in which the parties discussed their obligations. Build a timeline of who did what and when.
Then send a formal demand letter. Identify the specific contract provision that was broken, describe the harm, state the dollar amount you want, and give a deadline to respond, typically 14 to 30 days. Send it by certified mail so you have proof of delivery. A solid demand letter shows good faith if the case ends up in court, and it sometimes produces a settlement without one. Keep a log of every interaction after the dispute begins. Partial payments, offers to cure, or any acknowledgment of fault can be decisive at trial.
Where to File
Where the case goes 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 court is designed to work without an attorney, and the filing fee is either $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 roughly $36 to $320.11Washington Law Help. Ask the Court for a Fee Waiver
Serving the Defendant
After filing your Summons and Complaint, someone other than you has to hand-deliver copies to the defendant.12Washington State Legislature. RCW 4.28.080 – Summons, How Served A professional process server typically costs $50 to $100 per attempt; the county sheriff’s office is another option. If the defendant is a business, service has to go to the registered agent or an officer listed in the state’s business registry. Sloppy service can derail the whole case.
The Response Window
Once served, the defendant has 20 days to file a written response in Superior Court.13Washington Courts. CR 12 – Defenses and Objections No answer, and you can ask for a default judgment, which grants your requested damages without a trial. Most contract disputes in Washington settle before reaching a courtroom, but having the documentation organized from day one puts you in the strongest position whether the case ends at a settlement table or in front of a judge.
