Yes, you can file a stepparent adoption petition in the New Mexico District Court for your spouse's child, including a child born to unmarried parents. What shapes your case is the legal position of the child's other parent, and that depends on your facts.

Where the birth circumstances matter:

  • Whether a father is named on the birth certificate, whether paternity was ever established, or whether the father is unknown can all affect how the other parent's rights are addressed.
  • New Mexico law on how the court treats each of those situations should be confirmed with the District Court clerk in your county or with an attorney. This is especially important if the other parent might contest the adoption or cannot be identified.
  • You can order the birth certificate from New Mexico Vital Records and Health Statistics so you know exactly what it says before you begin.

What New Mexico's rules say:

  • Court: Stepparent adoptions are filed in the District Court under New Mexico Statutes Annotated Chapter 32A, Article 5.
  • Residency: There is no minimum residency period (NMSA 1978 § 32A-5-11).
  • Child's consent: The consent age is 14 (NMSA 1978 § 32A-5-17).
  • Abandonment: The period is 6 months (NMSA 1978 § 32A-5-15(B)(1)). Whether it applies to your situation is a question for the clerk or an attorney.
  • Home study: It is waived for stepparent adoptions (NMSA 1978 §§ 32A-5-14, 32A-5-31).

Paperwork to expect:

  • A Petition for Adoption.
  • Consent forms, or a motion to dispense with consent.
  • Your spouse's consent to the adoption.
  • Service on the other parent. New Mexico allows personal service by a sheriff or process server, or service by publication if that parent's location is unknown.

Cost and timeline: Court filing fees typically run $150-$300, and the total typically comes to under $1,000, compared with $3,000-$5,000+ when hiring an attorney. A stepparent adoption typically takes 3-6 months. For the exact fee in your county, ask the District Court clerk.

If the situation is not simple: If the father is unknown, was never involved, or might object, ask the clerk or an attorney how the court will handle that point before you file. We can prepare your paperwork, but we cannot decide those questions for you.
