Can I adopt my stepchild if there is an existing custody order in Washington?

Washington's stepparent adoption process runs through the Superior Court in your county, and an existing custody order is not listed among Washington's adoption requirements. How your specific order is treated once an adoption is filed or finalized is something to confirm with the Superior Court clerk or an attorney.

What matters more than the order itself: The court looks at whether the other parent's rights can be ended, either through consent or on grounds such as abandonment. Many custody orders involve a parent who is still legally in the picture, so this is usually the central question.

Abandonment in Washington: Washington sets no fixed number of months for abandonment. It depends on the parent's overall conduct (RCW § 26.33.120). If your custody order gives the other parent visitation or requires child support, the court looks at what has actually happened, not only what the order says. For example:

• Sporadic child support payments do not by themselves prevent an abandonment finding if the parent has not kept up meaningful contact with the child.
• Washington courts look at the overall relationship, not just financial contributions.
• If the other parent is actively involved or objects, your case may be contested. A contested case depends on its facts, so talk with an attorney about that issue.

Other requirements that still apply:

• Residency: Washington has no minimum residency period (RCW 26.33.030).
• Child's consent: A child who is 14 or older must consent (RCW § 26.33.160).
• Home study: Home study reports are not automatically waived for a child under 18 (RCW 26.33.220). Ask the clerk whether one will be needed in your case.
• Court: You file in the Superior Court of your county. Washington has 39 counties, and local procedures can differ slightly.

Your custody order in the paperwork: Keep a copy of your current custody order and any related orders handy. The court needs a full picture of the child's legal situation, and the clerk can tell you how your county wants existing orders presented.

Cost and timing: Court filing fees in Washington typically run $200-$500, and the total cost of a stepparent adoption without an attorney is typically under $1,000, compared with $3,000-$5,000+ with an attorney.
