Washington Adoption Law

Washington adoption law is codified primarily in RCW Chapter 26.33, and the legislative intent is stated plainly in section 26.33.010: to ensure that adoptions are handled efficiently while protecting the rights of biological parents, adoptive parents, and — above all — the child. The statute governs everything from who can file a petition, to how parental rights are terminated, to when the final decree is entered. Understanding this framework before you begin the process will save you from procedural surprises that routinely catch unprepared families off guard.

Here is how the law structures the adoption process in Washington, and what the paperwork requirements actually look like.

Jurisdiction: Where You File

Adoption petitions in Washington must be filed in the Superior Court of the county where the petitioners reside or where the adoptee is domiciled (RCW 26.33.030). Washington has 39 counties, and while the underlying statute applies statewide, the administrative execution varies significantly.

King County Superior Court maintains a dedicated Adoption Services department with standardized packets for different adoption types — stepparent, independent, adult — and employs adoption paralegals who review filings for technical accuracy before they reach a judge. In smaller counties, you will work more closely with the clerk's office or rely on private counsel to navigate the local motion docket scheduling.

Regardless of county, the filing fee is approximately $260, and the Superior Court is the only entity with authority to enter a Decree of Adoption.

The Core Documents

A complete adoption filing in Washington requires:

• Petition for Adoption — the formal request to the court
• Petitioner's Sworn Statement — background and financial declarations
• Birth parent relinquishments or consents — must be signed no earlier than 48 hours after the child's birth (RCW 26.33.080)
• Order Terminating Parental Rights — if TPR was involuntary under RCW 13.34.180
• Pre-placement report (home study) — conducted by a licensed CPA or social worker, valid for one year
• Post-placement reports — at least three social worker visits over the six-month supervision period
• Certified copy of the child's original birth certificate
• Adoption Service Notification Form
• Proposed Decree of Adoption

Missing any of these documents — or filing them with errors — will delay finalization. The pre-placement report alone requires background clearances (WSP, FBI, DCYF CAMIS), medical evaluations, financial documentation, personal references, and a home inspection under WAC 110-148 standards.

The 48-Hour Consent Rule

Washington law does not allow a birth parent to sign a relinquishment or consent to adoption until at least 48 hours after the child's birth. This is a hard legal floor with no exceptions. Once consent is executed before a judge or designated agency representative and approved by the court, it becomes irrevocable. For one year following, it can only be challenged by proving fraud, duress, or lack of mental competency.

This rule exists to protect birth parents from making decisions under the immediate physical and emotional stress of delivery. For adoptive families, it means the first 48 hours after birth are a period of legal uncertainty — the birth parent has every right to change their mind during this window.

The Six-Month Waiting Period

One of the most distinctive features of Washington adoption law is the six-month post-placement waiting period under RCW 26.33.230. The court will not enter a Final Decree of Adoption until the child has resided in the adoptive home for at least six months. Many other states finalize adoptions in 30 or 90 days; Washington's longer window is designed to ensure placement stability.

During this period, a post-placement reporter visits the home at least three times to observe the child's adjustment and the parents' caregiving. Some courts issue an "interlocutory order" (temporary order) at the beginning of this period, while others simply wait the full six months before entering the final decree.

For families, this period can feel like legal limbo. The child is in your home, you are parenting them daily, but the adoption is not final. Understanding that this is a standard supervisory period — not a window for the birth parent to reclaim the child after TPR — helps manage the anxiety.

The Putative Father Problem

Washington does not maintain a centralized Putative Father Registry. This is a critical gap that catches many families off guard. A historical legislative attempt to create one was removed, and the state did not adopt Article 4 of the Uniform Parentage Act.

Instead, Washington uses a notice-based system. An "alleged genetic parent" is entitled to notice of an adoption proceeding so they may assert their rights under RCW 26.33.030. For a child under one year old, a man's rights may be terminated without notice only if he failed to establish a legal relationship. For children over one year, notice is mandatory regardless.

The practical implication: your attorney must affirmatively identify and serve notice on any man who could potentially be the father. This is not a step you can skip. Failure to provide proper notice can result in an adoption being challenged or overturned.

ICWA and WICWA Overlay

Whenever a child who is a member of or eligible for membership in a federally recognized tribe is involved, both the federal Indian Child Welfare Act (ICWA) and Washington's own WICWA (RCW 13.38) apply. WICWA is stricter than the federal law in several ways — most notably requiring "active efforts" to prevent the breakup of the Indian family (a higher standard than the "reasonable efforts" required in non-Indian cases) and applying a "beyond a reasonable doubt" standard for TPR.

ICWA compliance is not optional, and it applies to all adoption types — not just foster care adoptions. If the court has "reason to know" a child may be an Indian child, tribal notice is mandatory.

Finalization Hearing

The finalization hearing is typically brief and ceremonial. The judge reviews all filed documents, confirms that legal requirements have been met, and signs the Decree of Adoption. The court then transmits the record to the State Registrar of Vital Statistics, and the Department of Health issues an amended birth certificate listing the adoptive parents.
