What are the adoption laws in New Mexico?

3 min readHelping families since 2001New Mexico

Adoption in New Mexico is governed mainly by New Mexico Statutes Annotated Chapter 32A, Article 5, and a stepparent adoption is filed in the District Court in your county. Adult adoption falls under a separate law. Here is how the rules work for families considering a stepparent adoption.

Where you file: New Mexico has 33 counties, and the case goes to the District Court in the county where your family files. Cities such as Albuquerque, Las Cruces, Rio Rancho, Santa Fe and Roswell are all served by their county's District Court. The clerk there can tell you about local forms and procedures.

Residency: New Mexico sets no minimum residency period for a stepparent adoption (NMSA 1978 § 32A-5-11).

Consent: A child who is 14 or older must consent to their own adoption (NMSA 1978 § 32A-5-17). Your filing typically includes a petition for adoption, consent forms or a motion to dispense with consent, and the spouse's consent to the adoption.

When a parent won't consent or can't be found: New Mexico uses a six-month abandonment period (NMSA 1978 § 32A-5-15(B)(1)). Whether it applies to your situation depends on your specific facts, so ask the District Court clerk or an attorney about contested cases. If the other parent's location is unknown, New Mexico allows service by publication. Otherwise, a parent can be served in person by the sheriff or a process server.

Home study: For stepparent adoptions, New Mexico waives the home study (NMSA 1978 §§ 32A-5-14, 32A-5-31).

Timeline: Stepparent adoptions typically take about 3-6 months, depending on the court's schedule and whether service or consent issues come up.

Cost: Court filing fees run about $150-$300. The total typically comes in under $1,000 when you file on your own, compared with roughly $3,000-$5,000+ when hiring an attorney.

Adult adoption: New Mexico also allows adult adoption under its separate Adult Adoption Act (NMSA 40-14-2 through NMSA 40-14-12 cover the key points). Key points:

  • An adult means someone 18 or older.
  • The adopter must be a New Mexico resident, meaning someone who has lived in the state for at least six months before filing or who is domiciled there with intent to remain.
  • Only the adoptee must consent, in writing, and a judge must approve the consent.
  • A hearing is required unless the court waives appearance for good cause. The court decides on clear and convincing evidence, and at least 30 days must pass after filing.
  • Adult adoptions typically take about 4-8 weeks.

Other details: The adoptee's parents and certain spouses must be served with an adult adoption petition. For questions about new birth certificates after the decree, the District Court clerk can point you in the right direction, and New Mexico Vital Records and Health Statistics handles the state's vital records.
