Can I adopt my stepchild if the bio father is in prison for a long sentence in Washington?

Yes, you can ask a Washington Superior Court to approve a stepparent adoption when your stepchild's biological father is in prison. How the case moves forward depends on whether he consents and on the facts of his relationship with your child.

Consent from the father. Washington's consent rules (RCW 26.33.160(1)) include parental consent for a child under 18. If he is willing to sign, that is the most straightforward path. Your child's own consent is also required if your child is 14 or older (RCW § 26.33.160).

If he won't sign or doesn't respond. Washington sets no fixed number of months for abandonment. The court looks at a parent's overall conduct (RCW § 26.33.120). That means:

• A prison sentence is one fact among many. The court looks at the whole picture, including contact, communication and involvement in your child's life.
• Sporadic child support does not prevent an abandonment finding if the parent hasn't kept up meaningful contact. Washington courts look at the overall relationship, not just money.
• Years of non-involvement typically support an abandonment finding.

How the court weighs the length of a particular sentence, and exactly how papers are delivered to someone in a correctional facility, are questions for the Superior Court clerk in your county or an attorney. If he contests the adoption, talk to an attorney about your specific facts.

Other Washington basics:

• Court: Superior Court in your county.
• Residency: Washington has no minimum residency period (RCW 26.33.030).
• Marriage length: Washington doesn't set a minimum marriage duration.
• Background check: Criminal background checks are required for adoptive parents.
• Home study: The rule is in RCW 26.33.220. Courts may waive it in some stepparent adoptions, so ask the clerk whether it applies to you.
• Timeline: Stepparent adoptions typically take 3-6 months.
• Cost: Court filing fees run $200-$500, and the total is typically under $1,000. Hiring an attorney for the whole process typically costs $3,000-$5,000+.

Washington courts are very supportive of stepparent adoptions. They understand that these adoptions give children stability and legal protection, and judges routinely approve adoptions that are in the child's best interest.

What to do next. Gather what you know about the father's contact with your child, such as letters, calls, visits and any support. Write down his last known facility and contact details. Then ask the Superior Court clerk how your county handles notice to an incarcerated parent. If you expect a fight, an attorney can advise you on that issue.
