When should I start the stepparent adoption process in Washington?

You can start the stepparent adoption process in Washington as soon as you're ready, because there is no minimum residency period and no minimum length of marriage to wait out. Washington does not set a waiting clock you have to run out first, so the best timing is usually when your family has decided and the paperwork is within reach.

Why there's no waiting period to worry about.

• Residency: Washington has no minimum residency period. Your case is filed in the Superior Court of the county where you live or where the child is domiciled (RCW 26.33.030).
• Marriage length: Washington doesn't specify a minimum marriage duration.
• Abandonment: There is no fixed number of months. If the other parent's rights are at issue, the court looks at that parent's overall conduct (RCW § 26.33.120), so there is no set date after which you become eligible.

Plan for the timeline. Stepparent adoptions in Washington typically take 3-6 months. If you want your family to be legally official before a milestone like a school year, a move, or a medical procedure, starting earlier gives you more breathing room. If the person being adopted is an adult, the typical timeline is shorter, about 4-8 weeks.

Timing points worth knowing.

• Child's consent: Washington sets the age of consent at 14 (RCW § 26.33.160). If your child is approaching that age, it's a good idea to gather your documents and talk with your child early.
• Background checks: Washington requires criminal background checks for adoptive parents, so allow time for those.
• Home study: Rules on home study are found at RCW 26.33.220. Whether and how they apply to your family is something the Superior Court clerk in your county can confirm. For an adoptee who is 18 or older, the preplacement and post-placement reports are not required.
• Other parent's consent: If the other parent has been out of the picture, or you aren't sure where they stand, how the court will handle your situation depends on your facts. Ask the clerk or an attorney about that specific issue before you file.

Costs and the vital records step. Court filing fees generally run $200-$500, and the typical total cost is under $1,000. An attorney-handled adoption commonly runs $3,000-$5,000+. After the adoption is final, you can ask the Washington State Department of Health Center for Health Statistics about the next steps for the child's records.

A simple way to decide. Ask yourself whether you have the basics ready: your marriage, the child's information, and a sense of where the other parent stands. If you do, nothing in Washington's requirements says you should wait. If something is unclear, such as the other parent's role, a call to your county's Superior Court clerk can settle it before you begin. In Washington's 39 counties, the filing steps are handled through the Superior Court, so the clerk's office is a reliable place to confirm local details.
