Can a non-citizen adopt a stepchild in Washington?

Possibly yes, but it depends on your individual situation. Washington's rule on who may adopt looks at age and competence: any person who is legally competent and 18 or older may be an adoptive parent (RCW 26.33.140(2)). How your immigration status fits in is a question to confirm with the Superior Court clerk in your county or an attorney, ideally one who handles immigration law.

What Washington's rules say that is relevant to you:

• Who may adopt: a legally competent person who is 18 or older (RCW 26.33.140(2)).
• Residency: Washington sets no minimum residency period for a stepparent adoption (RCW 26.33.030).
• Marriage: Washington doesn't specify a minimum marriage duration.
• Background checks: Washington requires criminal background checks for adoptive parents. If you have lived abroad, ask the clerk what the court will need to complete yours.
• Court: the case is filed in the Superior Court.

Consent and the other parent:

• If your stepchild is 14 or older, the child's consent is required (RCW § 26.33.160).
• If the other parent won't consent, the court may look at abandonment. Washington sets no fixed number of months. The court looks at the parent's overall conduct (RCW § 26.33.120).
• If the other parent is unknown, unreachable or contesting, talk to the court clerk or an attorney about that specific issue.

Questions to settle before you file:

• Whether your particular visa or immigration category raises any issue with the court. Green card holders, visa holders and others may be in different positions, so ask the clerk or an attorney about yours.
• Whether the clerk wants any extra identification or documents from you.
• Whether an immigration attorney should review your plans first. This matters most if your status is uncertain or you have questions about how the adoption relates to your immigration case.

Timeline and cost: A Washington stepparent adoption typically takes 3-6 months. Court filing fees run about $200-$500, and the total typical cost is under $1,000, compared with $3,000-$5,000+ for an attorney. Your county's clerk can confirm the exact fee.
