The other parent signs or the court decides
If the other parent will sign, we prepare the consent. If not, we prepare the notice, which is a routine step. In Washington, abandonment depends on the parent's overall conduct, with no fixed number of months.

Hearing, decree and new birth certificate
The judge holds a short hearing and signs your decree. We then prepare your request for a new birth certificate. You send it to the Washington State Department of Health Center for Health Statistics.
Washington State Department of Health Center for Health StatisticsDoes the other parent have to agree?
No. Courts want a two-parent home, and most families we help finish without the other parent's consent. In our experience, about 80% of the stepparent adoptions we have completed went forward without the other parent's consent. Of the 1,104 Washington families we have helped, many started with this same question.
They agree
If the other parent is willing, the process is simple. They sign a consent, and we prepare it for you in the form the Superior Court expects.
- We prepare the consent form
- The signing is quick and clear
- The court then schedules your hearing
They won't sign, or can't be found
If the other parent will not sign, is absent or cannot be found, Washington law gives the court a clear path.
- Washington sets no fixed number of months for abandonment.
- The court looks at the parent's overall conduct toward the child.
- When that conduct shows abandonment, the court has grounds to approve the adoption.
Notice to the other parent is routine, and we prepare it for you. In Washington, termination is not a separate case. It is part of the same adoption case.
RCW § 26.33.120One flat price. No surprises along the way.
The same decree, the same court, without attorney fees.
What Washington families tell us
Today we had our hearing for a step parent adoption. Our case was unusual in that my wife had adopted our daughter 5 years ago from Guatemala and now that we are married I wanted to adopt her as well. I was worried that because this child was adopted and the re-adopted that I would have some issues that I would have needed an attorney to sort out. Your staff did a fine job of making sure my paperwork addressed the situation correctly. I am extremely satisfied with the results as my hearing went off without a hitch. I would recommend your service to anyone needing to do a step parent adoption. Please feel free to place these comments on your web site if you wish. Thanks.
Just a quick note that with only a few hiccups, we were able to complete our adoption ourselves using your services. We are very pleased with the results and look forward to our son's new birth certificate arriving in a few weeks.
My experience with your company has been a pleasant one. They have worked with me, and have went as far as making changes for my forms 8 months later. They are a very pleasant group of people and very professional! So glad I choose them!!

Adopting an adult stepchild in Washington
Washington law says any person may be adopted, regardless of age or residence. There is no relationship or age-gap condition. The adoptee must consent if 14 or older, and parental consent is needed only for adoptees under 18. If you are married, your spouse must join the petition. You file in the Superior Court of the county where you live or the adoptee is domiciled. The home study is waived for an adoptee who is 18 or older, and the court schedules a hearing. Adult adoptions often finish in 4-8 weeks.
Three steps. That's the whole thing.
Our detailed Washington instructions make the process simple, and we are a phone call away at every step.

What Washington families ask us
How do I adopt my stepchild in Washington?
You file a petition in the Superior Court of your county. The other parent consents, or the court addresses their rights in the same case. Then the judge holds a hearing and signs the decree. We prepare every document, and most families finish in about 3-6 months.
Can I adopt my adult stepchild in Washington?
Yes. Washington says any person may be adopted, regardless of age or residence (RCW 26.33.140). The adult must consent, and your spouse must join the petition. The home study is waived for adoptees 18 or older, and these cases often finish in 4-8 weeks.
How much does a stepparent adoption cost in Washington?
Our complete package is $349, plus $99 for each additional child. The county clerk sets the Superior Court filing fee, so call the clerk to confirm it. Home study costs, where one applies, vary.
What if the other parent in Washington refuses to sign or can't be found?
You can still adopt. In our experience, about 80% of the stepparent adoptions we have completed went forward without the other parent's consent. Washington sets no fixed months for abandonment and looks at the parent's overall conduct (RCW § 26.33.120). We prepare the notice, and termination is handled in the same case.
Is a home study required for a stepparent adoption in Washington?
Washington does not waive the home study for a stepchild under 18 (RCW 26.33.220). It is waived only when the adoptee is 18 or older. We tell you what to expect and prepare your documents around it.
Does my child have to agree to the adoption in Washington?
A child who is 14 or older must consent (RCW § 26.33.160). We prepare the consent form for you to sign with your child.
Does my stepchild still get child support after a Washington adoption?
Yes, your stepchild is still supported. The other parent's duty to pay child support going forward ends when the adoption is final. As the child's legal parent, you take on a parent's duty of support. Support already past due is a separate matter under Washington law.
How does my stepchild get a new birth certificate in Washington?
After the judge signs the decree, you send a request to the Washington State Department of Health Center for Health Statistics. We prepare that request with your final papers.
