Do I have to wait after getting married before I can adopt my stepchild in Washington?

No, you don't have to wait after getting married. Washington doesn't set a minimum length of marriage before a stepparent can adopt, so there is no waiting period counted from your wedding date.

Residency: Washington has no minimum residency period for this kind of adoption (RCW 26.33.030). If you recently moved, that doesn't create a waiting period either. The Superior Court clerk in your county can confirm which court your case belongs in.

What can affect your timing: The wedding date isn't the issue. These steps are what take time:

• Consent from the child: Under RCW § 26.33.160, a child who is 14 or older must consent to the adoption. If your stepchild is close to that age, plan for it.
• Other parent's consent or abandonment: If the child's other parent won't consent, the case may turn on abandonment under RCW § 26.33.120. Washington sets no fixed number of months for abandonment. It depends on the parent's overall conduct. Because this depends on your facts, a contested situation, or one where the other parent can't be found, is best discussed with the court clerk or an attorney.
• Home study: Washington does not automatically waive the home study for a child (RCW 26.33.220). Ask the clerk whether it applies in your case.
• Background checks: Washington requires criminal background checks for adoptive parents, so allow time for that.

How long it takes: Stepparent adoptions in Washington typically take 3-6 months. That clock starts when you file, not when you marry. If you're already married, you aren't required to wait before starting.

Cost: Court filing fees in Washington typically run $200-$500, and a do-it-yourself route usually comes to under $1,000 in total. Hiring an attorney typically costs $3,000-$5,000+.

Practical tip: Even though there is no waiting period, the court will want a complete, accurate petition. Gathering your marriage certificate, your child's birth certificate and any information about the other parent first can save time. The Washington State Department of Health Center for Health Statistics is the agency to contact if you need certified vital records.
