New Mexico

Can a known donor renounce his legal obligations as a parent?

Yes; when parties to a donor agreement conform to the relevant New Mexico statute, the donor’s parental rights will be extinguished.

What if a known donor attempts to enforce his parental rights when the original intent was to be a sperm donor only?

If the donor “holds out” the child as his own over a sufficient period of time, he may be able to assert legal parentage rights.

Does the state allow for second-parent adoption (i.e., for same-sex couples)?

Some courts have permitted second-parent adoptions.  New Mexico will also recognize parentage of a same-sex partner of a woman who conceives through donor insemination without second-parent adoption.

Does the state allow for multiple-parent families (when the child has more than two adults in a parenting role)?

This may be possible; at least one court has recognized a multiple-parent family.

Does the state recognize “de-facto” or “psychological” parentage (of an “acting” parent without a biological connection) or a similar concept?

Yes.
