You may want to review the WA Residential Landlord-Tenant Act, particularly RCW 59.18.575 (Victim protection – Notice to landlord – Termination of rental agreement – Procedures). The RLTA is at http://apps.leg.wa.gov/RCW/default.aspx?cite=59.18 . If you qualify to use RCW 59.18.575, "Notwithstanding lease provisions that allow for forfeiture of a deposit for early termination, a tenant who terminates under this section is entitled to the return of the full deposit, subject to RCW 59.18.020 and 59.18.280. "
You should review the statutes carefully to see whether you qualify and how to qualify.
You should review your facts and options with your attorney.
