Wash. Rev. Code Ann. 9.96.070 & 9.96.060(3)
Washington State allows trafficking survivors who were convicted of prostitution as a result of the trafficking can apply to vacate the record of conviction. Survivors are not eligible to vacate a prostitution conviction if they have any pending criminal charges anywhere (including other states) or if they have been convicted of another crime, except prostitution, since the date of conviction. However, survivors who have been convicted of other offenses after the conviction they are seeking to vacate may still be eligible if they can prove that the later conviction was also a result of being trafficked.
Washington law also requires the survivor to give sworn testimony before the court at a hearing on the motion to vacate.
