RCW26.33.343 Search for Birth Parent or Adopted Child - Confidential Intermediary
An adopted person over the age of twenty-one years, or under twenty-one with the permission of the adoptive parent, or a birth parent or member of the birth parent's family after the adoptee has reached the age of twenty-one may petition the court to appoint a confidential intermediary. A petition under this section shall state whether a certified statement is on file with the department of health as provided for in RCW 26.33.347 and shall also state the intent of the adoptee as set forth in any such statement. The intermediary shall search for and discreetly contact the birth parent or adopted person, or if they are not alive or cannot be located within one year, the intermediary may attempt to locate members of the birth parent or adopted person's family. These family members shall be limited to the natural grandparents of the adult adoptee, a brother or sister of a natural parent, or the child of a natural parent. The court, for good cause shown, may allow a relative more distant in degree to petition for disclosure.
