The man on my child's birth certificate is not the biological father — how does this affect adoption in Washington?

The name on the birth certificate doesn't answer this question on its own, and when the listed father isn't the biological father, who must consent or have their rights addressed depends on your family's facts. For that specific issue, confirm with the Superior Court clerk in your county or with a family law attorney before you file. Here is what we can tell you about how a Washington stepparent adoption works around it.

Where the case is filed: Stepparent adoptions are handled by the Superior Court in your county. The adoption law is Revised Code of Washington Chapter 26.33.

Consent and abandonment: If a parent will not consent, Washington looks at abandonment under RCW § 26.33.120. There is no fixed number of months. Abandonment depends on the parent's overall conduct. This matters if the man on the birth certificate has been out of the picture, and the same question may arise for a biological father who has never been involved. Whether a particular man counts as a parent whose consent or abandonment finding is needed is a fact-specific question for the clerk or an attorney.

If your child is 14 or older: Your child's own consent is required (RCW § 26.33.160).

Other requirements that still apply:

• Residency: There is no minimum residency period.
• Background checks: Washington requires criminal background checks for adoptive parents.
• Home study: The court may waive the home study in some stepparent adoptions. The home study rules are in RCW 26.33.220, and the clerk can tell you how they apply to your child's situation.

Timeline and cost: A stepparent adoption in Washington typically takes about 3-6 months. Court filing fees generally run $200-$500, and the total typically stays under $1,000. Attorney representation commonly costs $3,000-$5,000 or more.

Birth certificate records: The Washington State Department of Health Center for Health Statistics is the agency that holds birth records. If you are unsure what your child's certificate says or how it was completed, start by getting a copy.

Questions to settle before filing:

• Who is named on the birth certificate, and who is the biological father?
• Is the man on the certificate willing to consent, or has he been absent?
• Has any other man been involved with your child or been identified as the father?
• Is your child 14 or older?

Your answers shape which documents you need and whether you want an attorney to look at one specific issue.
