Yes, you can ask a Washington Superior Court to approve a stepparent adoption of your special needs stepchild. Washington's adoption law (RCW 26.33.140) says any person may be adopted, regardless of age or residence. The steps below are the ones that apply to stepparent adoptions in Washington. Washington law on how a particular disability affects the case should be confirmed with the Superior Court clerk in your county or an attorney.

Where it is filed: You file in the Superior Court. Venue rules are in RCW 26.33.030. Washington has no minimum residency period.

Consent from the other parent: If the other parent will not or cannot consent, the case may turn on abandonment (RCW § 26.33.120). Washington sets no fixed number of months. Abandonment depends on the parent's overall conduct. If this is contested, or the other parent's whereabouts are unknown, talk to an attorney or the court clerk about your specific facts.

Your stepchild's consent: Washington requires the child's consent at age 14 or older (RCW § 26.33.160). If your stepchild is 14 or older and has a disability that affects understanding or communication, ask the Superior Court clerk or an attorney how the court handles consent in that situation.

Background checks and home study: Washington requires criminal background checks for adoptive parents. Home study rules are in RCW 26.33.220. A home study is not automatically waived in every case, so ask the clerk whether it applies to you.

Why many families pursue it:

  • Legal decision-making security for medical, school, and daily-life choices
  • The emotional security of a legally unified family
  • Possible access to benefits such as Social Security survivor benefits

Benefits and coverage: If your stepchild receives SSI, disability benefits, or Medicaid, check with the agency that administers them, and with an attorney, before you file. How adoption affects a particular benefit depends on the program and your situation.

Timeline and cost: Stepparent adoptions in Washington typically take 3-6 months. Court filing fees generally run $200-$500, and the total typical cost is under $1,000. Attorney-handled adoptions often cost $3,000-$5,000+. Ask the Superior Court clerk in your county for the exact current fee.
