Washington Revised Code Title 26. Domestic Relations § 26.51.040. Hearing--Procedure

(1) If a party asserts that they are being subjected to abusive litigation, the court shall attempt to verify that the parties have or previously had an intimate partner relationship and that the party raising the claim of abusive litigation has been found to be a victim of domestic violence by the other party. If the court verifies that both elements are true, or is unable to verify that they are not true, the court shall set a hearing to determine whether the litigation meets the definition of abusive litigation.

(2) At the time set for the hearing on the alleged abusive civil action, the court shall hear all relevant testimony and may require any affidavits, documentary evidence, or other records the court deems necessary.
