Class action lawsuits in Washington state let one or a few plaintiffs sue on behalf of a large group that suffered the same harm, and the case proceeds under Superior Court Civil Rule 23. A judge has to certify the class before it can move forward as a group case, notice goes out to every member the lawyers can identify, and anyone who does not opt out is bound by the final judgment or settlement. Filing a civil complaint costs $290 in most counties.1Washington State Legislature. Washington Code RCW 36.18.020 – Clerk Fee Schedule
What Qualifies a Case for Class Treatment
A lawsuit is not a class action just because the complaint calls it one. Under Civil Rule 23, a Washington Superior Court judge has to find that the proposed group meets four prerequisites before certifying the class.2Washington Courts. Washington Superior Court Civil Rule 23 – Class Actions
- Numerosity. The group has to be large enough that joining every member individually would be impractical. Courts generally treat around 40 or more as enough, though judges can certify smaller groups when the circumstances justify it.
- Commonality. There must be shared questions of law or fact running through the whole group, not just issues unique to a few people.
- Typicality. The lead plaintiff’s claims have to closely mirror those of the rest of the class. A representative in a very different situation from other members will not clear this bar.
- Adequacy. The court must be satisfied that the lead plaintiff and the lawyers will competently protect the whole group’s interests.
Clearing all four is necessary but not enough on its own. CR 23(b) requires the judge to also find that a class action is the right procedural vehicle. One common ground is that separate individual lawsuits would risk inconsistent rulings that leave the defendant facing contradictory obligations. Another is that the common legal and factual questions predominate over individual ones, so a single proceeding is more efficient than dozens or hundreds of trials.
Deadlines to File
The filing deadline turns on the type of claim, and missing it kills the case.3Washington State Legislature. Washington Code Chapter 4.16 RCW – Limitations of Actions
- Written contracts: six years from the breach.
- Oral contracts: three years.
- Personal injury and property damage: three years.
- Fraud: three years from discovery, not from when it occurred.
Consumer protection claims brought by private parties generally follow the three-year residual limitations period. Claims brought by the state on behalf of the public have no time limit.
Filing a Class Action Pauses the Clock for Members
Under a doctrine called American Pipe tolling, the statute of limitations pauses for every member of a proposed class the moment the class action is filed. If the case later falls apart because certification is denied or the lead plaintiff settles individually, class members can still file their own lawsuits using whatever time was left on the clock when the class action began. The tolling protects individual follow-up claims only. The Supreme Court has held that it does not extend the deadline for a second class action based on the same claims.
Filing the Case
Preparation happens well before anything reaches the courthouse. The legal team defines the proposed class precisely so every member shares a clearly identifiable connection to the alleged harm. They gather contracts, billing records, employment documents, or whatever else demonstrates the common injury. Picking the lead plaintiff means finding someone whose claims are strong, whose background can withstand scrutiny, and who has no conflicts with the rest of the group.
The complaint has to lay out the legal claims, identify every defendant, and describe the relief the class is seeking, which can be money damages, an order stopping a harmful practice, or both. Defining the start and end dates of the alleged misconduct helps the court understand the scope of the proposed class.
The representative plaintiff files with the Clerk of the Superior Court in the appropriate county. The civil filing fee is $290 in most counties, which combines a statutory base fee and a judicial surcharge. Some counties add local fees, so it is worth checking with the specific clerk’s office beforehand.
After filing, the plaintiff has to formally serve the defendant with the summons and complaint. Washington allows service by any person 18 or older who is not a party to the case: a friend, a professional process server, or the county sheriff. An individual is typically served in person or by leaving papers at their home with a resident of suitable age. A corporation is served through its registered agent, president, or another designated officer.4Washington State Legislature. Washington Code RCW 4.28.080 – Summons, How Served
When the Case Gets Moved to Federal Court
Filing in Superior Court does not guarantee the case stays there. Under the Class Action Fairness Act, a defendant can remove the case to federal court when three conditions are met: the total amount at stake across all class members exceeds $5 million, there are at least 100 proposed class members, and at least one class member lives in a different state from at least one defendant.5Office of the Law Revision Counsel. United States Code Title 28 Section 1332 – Diversity of Citizenship Individual claims add together to reach the $5 million threshold, so a case where each member lost a small amount can still qualify if the class is large.
CAFA has exceptions built to keep genuinely local disputes in state court. The main one is the local controversy exception, which applies when more than two-thirds of class members are citizens of the state where the case was filed, at least one defendant is also from that state, and the principal injuries happened there. When it applies, the federal court has to send the case back. Plaintiffs’ lawyers who want to stay in Washington state court often structure their class definitions with these exceptions in mind.
Certification, Notice, and Your Right to Opt Out
Once the case is filed, the plaintiff has to move for class certification, and CR 23 directs the court to rule as soon as practicable. Both sides present evidence and arguments on whether the prerequisites and the CR 23(b) grounds are satisfied. If the judge certifies the class, the case moves into discovery and eventually trial as a class action. If certification is denied, the lead plaintiff can still pursue an individual claim, and other members keep the right to file their own lawsuits with the benefit of American Pipe tolling. Certification decisions are sometimes appealed, and judges occasionally revisit their own orders as new facts develop.
After certification, the legal team has to send notice to every identifiable member. CR 23(c)(2) requires the best notice practicable, which typically means individual notice by mail or email to everyone reasonable effort can identify. The notice explains the nature of the lawsuit, describes who is in the class, and spells out each member’s rights.
The most important right is opting out. Any member who prefers to pursue a separate lawsuit can request exclusion by a deadline the court sets. Anyone who does not opt out is automatically included and bound by whatever happens, favorable or not. Included members share in any recovery but lose the right to sue the defendant separately over the same conduct. Opting out preserves your individual claim but forfeits any share of the class recovery.
Settlement, Attorney Fees, and Incentive Awards
No class action can be dismissed or settled without the judge’s approval. Under CR 23(e), notice of any proposed settlement goes out to all class members, and the court holds a fairness hearing where members can object or voice support. The judge evaluates whether the deal is fair, reasonable, and adequate given the risks of continued litigation. If approved, a claims administrator handles verifying eligibility and distributing payments.
Class action lawyers almost always work on contingency and collect a percentage of the recovery rather than billing hourly. Courts use two main approaches to check whether fees are reasonable. Under the percentage-of-fund method, fees typically run 20% to 45% of the total settlement. Under the lodestar method, the court multiplies reasonable hours by a reasonable hourly rate and may apply a multiplier for complexity. Most courts cross-check one against the other so the fee does not consume an outsized share of the class recovery.
The court also reviews any incentive award for the lead plaintiff, which compensates them for the time and effort of representing the class. These awards typically fall in the $3,000 to $5,000 range, though they vary with the complexity of the case and the plaintiff’s involvement.
Taxes on What You Receive
Settlement money can be taxable, and class members often miss this. The IRS treats most settlement payments as taxable income unless a specific exclusion applies. The main exclusion covers damages received for personal physical injuries or physical sickness, which are tax-free regardless of amount.6Office of the Law Revision Counsel. United States Code Title 26 Section 104 – Compensation for Injuries or Sickness
Everything else is generally taxable. Settlements for consumer overcharges, employment violations, emotional distress without a physical injury, and lost wages all count as income. Punitive damages are always taxable. If your share exceeds $600, expect a tax form from the claims administrator. Set aside a portion of any non-physical-injury settlement for taxes rather than spending the full amount and facing a bill at filing time.
