You may be able to, but whether you can file a stepparent adoption while a custody case is still open depends on the facts of your case. The Superior Court clerk in your county, or a family law attorney, can confirm how the court handles that timing for your situation. Here is what we can tell you about how Washington's adoption process works, so you can plan your next step.
Where the case is filed: Stepparent adoptions in Washington are handled by the Superior Court in your county. If a custody case is open, the clerk can tell you how a new adoption filing would relate to it.
Washington requirements that apply to your planning:
- Residency: Washington has no minimum residency period for adoption (RCW 26.33.030).
- Child's consent: A child who is 14 or older must consent (RCW § 26.33.160).
- Abandonment: Washington sets no fixed number of months. Abandonment depends on the other parent's overall conduct (RCW § 26.33.120). Courts look at the whole relationship between that parent and the child, not just one factor such as sporadic child support.
- Home study: It is not automatically waived (RCW 26.33.220). The clerk can tell you what applies in your county.
- Background checks: Adoptive parents must complete criminal background checks.
Why the custody case matters: An open custody case usually means the other parent is actively involved and may contest. If that parent will not consent, the question becomes whether the facts support an abandonment finding. That depends on their conduct, so it is worth getting advice from an attorney on that specific issue before you file. If custody has been resolved and the other parent's role is settled, your path may be simpler, but the clerk or an attorney should confirm that for your case.
Timing and cost: Once filed, a Washington stepparent adoption typically takes 3-6 months. Court filing fees generally run $200-$500, and the total typically comes to under $1,000 when you prepare the paperwork yourself. Attorney-handled adoptions often cost $3,000-$5,000+. Washington courts are generally supportive of stepparent adoptions because they give children stability and legal protection, and judges routinely approve adoptions that are in the child's best interest.
Questions to ask before you file:
- Is there a pending custody or parenting-plan case, and which court and county is it in?
- Has the other parent consented, or will consent be contested?
- Does your county require a home study in your situation?
- Does the court want the custody matter resolved first?
The clerk can answer the procedural questions, and an attorney can advise on contested issues or on how the two cases affect each other.
