Second Parent Adoption in Oregon: A Guide for Same-Sex and Unmarried Couples

Second-parent adoption is one of the most practically important legal steps an LGBTQ+ family or unmarried couple can take in Oregon. It gives a non-biological parent — the partner who did not carry the child or does not appear on the original birth certificate — full, legally recognized parental rights that are completely independent of their relationship with the other parent.

Without it, the non-biological parent has no legal standing if the relationship ends, if the biological parent dies or becomes incapacitated, or if a school, hospital, or government agency requires proof of parentage. In Oregon, second-parent adoption is the cleanest legal solution to all of these risks.

What Is Second-Parent Adoption?

Second-parent adoption is an adoption by a second parent that leaves the first parent's rights intact. It is distinct from stepparent adoption in one critical way: in stepparent adoption, there is always a non-custodial biological parent whose rights are being terminated. In second-parent adoption, the adoptive parent is typically a same-sex partner or unmarried co-parent, and both parents retain full parental rights after the adoption is finalized.

Oregon courts have recognized second-parent adoptions since the 1990s. According to Oregon's Non-Departmental Adoptions Program data, second-parent adoptions have been a consistent category of filings — with 44 filings in FY 2022-23, 33 in FY 2023-24, and 50 in FY 2024-25 — reflecting stable and ongoing demand from Oregon families.

Who Can File a Second-Parent Adoption in Oregon?

Oregon law permits second-parent adoptions by same-sex partners, unmarried domestic partners, and other non-biological parents who have established a parental relationship with the child. The state's Oregon Equality Act of 2008 prohibits discrimination based on sexual orientation and gender identity in public accommodations, housing, and employment, and Oregon's non-discrimination protections extend to the adoption process under ORS 418.648(10).

Same-sex couples who are married and both appear on the child's birth certificate do not need a second-parent adoption — the birth certificate itself establishes both parents' legal status. Second-parent adoption becomes critical when the non-biological parent is NOT listed on the birth certificate, or when the birth certificate was issued by another state or country that may not recognize both parents.

Unmarried couples — regardless of sexual orientation — face the same issue. If only one partner is listed as a parent on the child's birth certificate, the other has no automatic legal standing, even if they have been raising the child together.

The Legal Process in Oregon

Second-parent adoption follows the general adoption petition process under ORS Chapter 109, filed in the Oregon Circuit Court of the county where you reside. The specific procedural steps:

1. Confirm you need a second-parent adoption. If your child was born or adopted while you were legally married and both of you are listed as parents on the birth certificate, adoption may be unnecessary. Consult with an Oregon family law attorney to confirm your current legal status before filing.

2. Complete the home study (or apply for a waiver). Like other adoptions, second-parent adoptions technically require a home study under ORS 109.276. However, if the child has resided continuously with the petitioning second parent for at least one year, and the child has been in the legal parent's home since birth or infancy, the court may waive the full home study. Even with a waiver, all adult household members must complete Oregon State Police criminal background checks and ODHS child abuse registry checks.

3. File the Petition for Adoption. Your adoption attorney files the petition in the local Circuit Court, along with the ASSIS (Adoption Summary and Segregated Information Statement), the background check clearances, the existing legal parent's written consent to the adoption, and a placement report or home study.

4. Serve ODHS. The petition and supporting documents must be served to the ODHS Director's Non-Departmental Adoptions Unit within 30 days of filing. ODHS then has a 90-day review window before the finalization hearing can be scheduled.

5. Attend the finalization hearing. The hearing is typically brief and held in chambers. Both parents and the child attend. The judge reviews the documents, confirms statutory compliance, and signs the Judgment of Adoption.

6. Receive the amended birth certificate. Oregon Health Authority issues a new birth certificate listing both parents, typically within 4 to 8 weeks after finalization.

The Consent Requirement

Because second-parent adoption leaves the first parent's rights intact, there is no termination of parental rights involved. The legal parent — the biological parent or the parent currently listed on the birth certificate — must give written, notarized or witnessed consent to the adoption. This is typically straightforward when both partners are committed to the process, but it does require the filing formalities to be followed correctly.

If the legal parent and petitioning second parent are no longer together and there is conflict, the process becomes more complex. The legal parent's consent cannot be bypassed in a second-parent adoption the way it can sometimes be in a stepparent adoption (through proving abandonment). Both parents must be on board.

Why This Matters More Than You Think

Many LGBTQ+ families in Oregon assume that their domestic partnership or marriage, combined with the non-biological parent's consistent role in the child's life, provides sufficient legal protection. In most everyday situations, it does. But in edge cases — a medical emergency where the biological parent is unreachable, a custody dispute after separation, a school that demands documentation of legal parentage, or an interstate move to a less progressive state — the absence of a formal adoption judgment creates real legal vulnerability.

A completed second-parent adoption gives the non-biological parent parental rights that cannot be revoked without a separate legal proceeding, are recognized in all 50 states under the Full Faith and Credit Clause, and survive the death of the biological parent without probate complications.

It also simplifies future decisions. Adding a non-biological parent to school enrollment, medical consent, and tax filings requires proof of legal parentage. A finalized adoption judgment is definitive proof.

Finding an Attorney

Not all Oregon family law attorneys have practical experience with second-parent adoptions. The attorneys who specialize in LGBTQ+ family law and adoption — firms like Litowich Law in Portland, which focuses specifically on LGBTQ+ families — understand the specific procedural requirements and have established relationships with the courts that regularly process these petitions.

The Oregon State Bar Lawyer Referral Service (503-684-3763) can connect you with family law attorneys in your area. When you call, specify that you need an attorney with experience in second-parent or LGBTQ+ adoption, not just general family law.

Attorney costs for second-parent adoption in Oregon typically run $2,000 to $5,000 for uncontested cases. The court filing fee is $263 under ORS 21.135.

After the Adoption

Once finalized, both parents hold identical parental rights and responsibilities under Oregon law — no different than if the child had been born to both parents. The Judgment of Adoption is the controlling legal document. Keep certified copies in a secure location and provide copies to your child's school, your health insurance provider, and your estate planning documents.
