Adoptions are filed in the Superior Court of the county in the State of Washington, in which the adoptive parents lived when the adoption occurred. In some cases, a relinquishment of parental rights may have been filed in a different county than the adoption. In this instance, you would have to contact the Clerk of the Court in that county, since each Clerk is only authorized to search records within their own county.
