N.M. Stat. § 45-5A-203
Jurisdiction.
A New Mexico court has jurisdiction to appoint a guardian or issue a protective order
for a respondent if:
A. New Mexico is the respondent's home state;
B. on the date the petition is filed, New Mexico is a significant-connection state and:
(1)
the respondent does not have a home state or a court of the respondent's
home state has declined to exercise jurisdiction because New Mexico is a more
appropriate forum; or
(2)
the respondent has a home state, a petition for an appointment or order is
not pending in a court of that state or another significant-connection state and, before
the court makes the appointment or issues the order:
(a) a petition for an appointment or order is not filed in the respondent's home
state;
(b) an objection to the court's jurisdiction is not filed by a person required to
be notified of the proceeding; and
(c) the court in New Mexico concludes that it is an appropriate forum pursuant
to the factors set forth in Section 45-5A-206 NMSA 1978;
C. New Mexico does not have jurisdiction pursuant either to Subsection A or B of
this section, the respondent's home state and all significant-connection states have
declined to exercise jurisdiction because New Mexico is the more appropriate forum and
jurisdiction in New Mexico is consistent with the constitutions of New Mexico and the
United States; or
D. the requirements for special jurisdiction pursuant to Section 45-5A-204 NMSA
1978 are met.
