Legal Framework and Considerations
- AI: Recognized by Statute
- NI: Not Recognized
- Sperm donor agreement: Unknown — no clear public safe harbor

Case excerpt — Mintz v. Zoernig, 2008-NMCA-162, 145 N.M. 362, 198 P.3d 861 (N.M. Ct. App. 2008) (published; pre–UPA-2002 law): Known friend provided sperm; mother “used a syringe-like implement” and impregnated herself “Without the assistance of a licensed physician.” Pre-conception deal said he would be a male role model but have no support duty. Held: (1) The old artificial-insemination statute (former § 40-11-6) “does not apply” because “the plain language of the statute requires the semen be provided to a licensed physician” and here it was not. (2) Father was the children’s natural father under holding-out / acknowledgment presumptions (visitation, registered as father, stipulated order). (3) “We hold that the agreements are not enforceable and that Father must therefore pay child support for both children”—he could not keep parental rights while contracting out of support. “Where the biological father goes beyond merely donating sperm and assumes a parental role, as in this case, he is liable for child support.” Intermediate appellate. Chronology: decided under the old UPA-style AI statute, before New Mexico’s 2009 adoption of modern Article 11A. Still the leading published known-donor AI opinion; read together with current § 40-11A-702. July 2026.
New Mexico’s legal framework for informal sperm donation, including at-home artificial insemination (AI), is governed by the 2002 Uniform Parentage Act (UPA), enacted in 2009 via 2009 N.M. Laws ch. 215 and codified in N.M. Stat. Ann. Chapter 40, Article 11A (§ 40-11A-101 et seq.). This progressive statute prioritizes intent over procedure, exempting donors from paternity without mandating physician involvement, aligning New Mexico with permissive states like Nevada and Oregon. The focus on signed records for consent adds a layer of formality, with limited case law as of October 2025 providing interpretive guidance. Enhanced via 2025 S.B. 417 for confirmatory adoptions in assisted reproduction.
Core Provisions
| Provision | Statute | Key Implications |
|---|---|---|
| Assisted Reproduction | § 40-11A-102(D) | Defines as a method of causing pregnancy other than sexual intercourse, including intrauterine insemination, egg/embryo donation, IVF, and intracytoplasmic sperm injection. Broadly encompasses at-home AI; no physician required. |
| Donor Non-Parentage | § 40-11A-702 | Donors have no parental rights or duties for children conceived via assisted reproduction. Applies to informal AI; protects against support/custody claims without physician mandate unless agreed otherwise in signed record. |
| Intent-Based Parentage | § 40-11A-703 & § 40-11A-704 | Individuals consenting with intent to parent are parents; consent via signed record. Absent record, proven by evidence. Presumptions for spouses; donors excluded by default. |
| Custody & Child Support | § 40-11A-301 (Acknowledgment) & Chapter 40, Article 4 (Support) | Non-parents (donors) owe no support; custody defaults to birth/intended parents. Disputes resolved via intent evidence, not biology alone. |
| Withdrawal/Disputes & Surrogacy | § 40-11A-801 et seq. (Surrogacy) | Consent revocable pre-insemination; surrogacy requires agreements with validation. Informal donation under broader UPA; cross-state via UIFSA. |
Key court cases
- Mintz v. Zoernig, 2008-NMCA-162, 198 P.3d 861 (N.M. Ct. App. 2008) — Ruling: At-home known-donor AI without a licensed physician fell outside the old AI statute. The genetic provider, who held himself out as father and exercised visitation, was the natural father and owed child support despite pre-conception agreements saying he would not. Court: pure anonymous or pure physician-path donation is different; you cannot keep parent-like rights and contract away support. Chronology: pre–Article 11A (2009). Modern § 40-11A-702 is more donor-protective for assisted reproduction—but Mintz still warns that post-birth parental conduct can re-create support duties.
- Modern code: After 2009, § 40-11A-702 states a donor is not a parent of a child conceived by assisted reproduction. Document non-parent intent; do not “act like dad” if you mean to stay a donor.
Bottom line: Current statute is relatively protective for true donors; Mintz shows the high-risk pattern is informal AI + known provider + parental involvement + “no support” side deal. Reviewed July 2026.
Practical Steps & Risks
- Documentation: Intended parents and donor should sign a pre-conception agreement clarifying non-parental intent (§ 40-11A-702). Not mandatory for exemption but crucial evidentiary tool; can also establish intended parent rights (§ 40-11A-703).
- Health Screens: Obtain private STI and genetic carrier tests; no state mandate for informal arrangements, but essential to mitigate risks, especially in rural areas.
- Non-Bio Parent Rights: For couples, use signed consent to assisted reproduction (§ 40-11A-703) or acknowledgment (§ 40-11A-301) post-birth to secure the non-birthing parent's rights and reinforce donor exclusion—simpler/cheaper than adoption (§ 32A-5-11, enhanced by 2025 S.B. 417 for confirmatory process). Married spouses get automatic presumption (§ 40-11A-204).
- Risks: Natural insemination (NI) not protected—biology presumes paternity. Undocumented AI vulnerable if intent challenged; out-of-state moves may invoke UIFSA. New Mexico's progressive stance favors exemptions with documentation.
