Can a stepmother adopt her husband's child in Washington?

Yes. In Washington, a stepmother can adopt her husband's child by petitioning the Superior Court in your county, and the process is the same as for any other stepparent adoption. Washington law on adoption is in the Revised Code of Washington Chapter 26.33, and any person who is legally competent and 18 or older may be an adoptive parent (RCW 26.33.140).

What matters for a stepmother in Washington:

• Court: Your petition is filed in the Superior Court. Washington has 39 counties, and the clerk in your county can tell you about local filing steps.
• Residency: There is no minimum residency period (RCW 26.33.030).
• Length of marriage: Washington does not set a minimum marriage duration.
• Background check: Washington requires criminal background checks for adoptive parents.
• Child's consent: A child who is 14 or older must consent (RCW § 26.33.160).
• Home study: It is not automatically waived (RCW 26.33.220). Washington allows courts to waive it for stepparent adoptions in some situations, so ask the Superior Court clerk whether your family's situation qualifies.

If the child's birth mother is not involved: This is often the biggest question. Washington sets no fixed number of months for abandonment. The court looks at the parent's overall conduct (RCW § 26.33.120). Occasional child support does not prevent an abandonment finding if the parent has not kept up meaningful contact with the child, because courts look at the whole relationship, not only money. Whether abandonment applies depends on your facts. If the birth mother is actively involved, objects, or cannot be found, talk with the Superior Court clerk or an attorney about your specific situation.

Timeline and cost: A stepparent adoption in Washington typically takes 3-6 months. Court filing fees generally run $200-$500, and the total typical cost is under $1,000.
