Served with a lawsuit, facing an arbitration demand, or expecting one? The 8 Seattle firms below defend businesses in commercial disputes — from a $250,000 partnership fight in King County Superior Court to a bet-the-company federal class action in the Western District of Washington.
Updated 2026-05-02
Most Seattle commercial cases land in one of three forums: King County Superior Court (for state-law disputes between Washington parties), the U.S. District Court for the Western District of Washington (federal-question, diversity, IP, securities), or American Arbitration Association / JAMS arbitration (when the underlying contract has an arbitration clause). Picking a firm that knows the forum matters — local judges have known preferences on case management, scheduling orders, and dispositive motions.
Washington has a few procedural traits worth knowing before you sign an engagement letter. The state requires extensive pre-discovery disclosures and uses a mandatory arbitration program (MAR) for civil cases under a damages threshold. The Western District of Washington's local rules are tight on summary-judgment procedure and electronic-discovery protocols. Litigation defense in Seattle is also unusually likely to involve IP, securities, or tech-platform claims, given the city's industry mix.
Three buckets of firms. Litigation boutiques (Corr Cronin, Tomlinson Bomsztyk Russ, Ember Law, Cook & Bartlett) handle commercial disputes at boutique rates and frequently sit first chair at trial. Mid-market full-service (Lasher Holzapfel, Carney Badley Spellman) pair litigation with corporate counsel for ongoing clients. BigLaw (Davis Wright Tremaine, Perkins Coie, K&L Gates) handle the largest, most complex matters — typical engagement runs $1M+ in fees and 18–36 months to trial.
