Can a stepfather adopt his wife's child in Washington?

Yes, a stepfather can adopt his wife's child in Washington. The adoption is filed in the Superior Court in the county where you live or where the child is domiciled (RCW 26.33.030), and a stepfather who is married to the child's mother is the situation stepparent adoption exists for.

What you will need to meet:

• Marriage: You should be legally married to the child's mother. Washington doesn't specify a minimum length of marriage.
• Your eligibility: An adoptive parent must be legally competent and at least 18 (RCW 26.33.140(2)).
• Residency: Washington has no minimum residency period. The Superior Court clerk can confirm the venue rules for your county.
• Background check: Washington requires criminal background checks for adoptive parents.
• The child's consent: A child who is 14 or older must consent (RCW § 26.33.160). For a younger child, no consent from the child is required.

The child's father: This is often the biggest question. In general, the biological father either consents to the adoption or the court finds that he has abandoned the child (RCW § 26.33.120). Washington sets no fixed number of months for abandonment. The court looks at the parent's overall conduct. Sporadic child support doesn't automatically prevent an abandonment finding, because Washington courts look at the whole relationship, not just money. If the father hasn't been involved for years but never formally gave up his rights, that doesn't automatically block the adoption. If he might contest it, or if you don't know where he is, the details depend on your facts. Talk to the Superior Court clerk or an attorney about that specific issue.

Home study: Washington's home study rules are in RCW 26.33.220. A home study is not automatically waived in every stepparent adoption, although Washington allows courts to waive it in some stepparent cases. Ask the clerk whether the court in your county will require one for your family.

Timeline and cost: A stepparent adoption in Washington typically takes 3-6 months. Court filing fees generally run $200-$500, and the total typically comes to under $1,000. Hiring an attorney commonly costs $3,000-$5,000+. After the adoption, the Washington State Department of Health Center for Health Statistics is the agency that handles vital records, and the court clerk can explain how to update the child's records.

Why families do it: Adoption can bring Social Security survivor benefits, legal decision-making security, and the emotional security of a unified family.
