N.M. Stat. § 46-7-29
Renunciation, resignation, death or removal of custodian;
designation of successor custodian.
A. A person nominated under Section 4 [46-7-14 NMSA 1978] of the Uniform
Transfers to Minors Act or designated under Section 9 [46-7-19 NMSA 1978] of that act
as custodian may decline to serve by delivering a valid disclaimer to the person who
made the nomination or to the transferor or to the transferor's legal representative. If the
event giving rise to a transfer has not occurred and no substitute custodian able, willing
and eligible to serve was nominated under Section 4 of that act, the person who made
the nomination may nominate a substitute custodian under Section 4 of that act;
otherwise, the transferor or the transferor's legal representative shall designate a
substitute custodian at the time of the transfer, in either case from among the persons
eligible to serve as custodian for that kind of property under Subsection A of Section 10
[46-7-20 NMSA 1978] of that act. The custodian so designated has the rights of a
successor custodian.
B. A custodian at any time may designate a trust company or an adult other than a
transferor under Section 5 [46-7-15 NMSA 1978] of the Uniform Transfers to Minors Act
as successor custodian by executing and dating an instrument of designation before a
subscribing witness other than the successor. If the instrument of designation does not
contain or is not accompanied by the resignation of the custodian, the designation of the
successor does not take effect until the custodian resigns, dies, becomes incapacitated
or is removed.
C. A custodian may resign at any time by delivering written notice to the minor if the
minor has attained the age of fourteen years and to the successor custodian and by
delivering the custodial property to the successor custodian.
D. If a custodian is ineligible, dies or becomes incapacitated without having
effectively designated a successor and the minor has attained the age of fourteen
years, the minor may designate as successor custodian, in the manner prescribed in
Subsection B of this section, an adult member of the minor's family, a conservator of the
minor or a trust company. If the minor has not attained the age of fourteen years or fails
to act within sixty days after the ineligibility, death or incapacity, the conservator of the
minor becomes successor custodian. If the minor has no conservator or the conservator
declines to act, the transferor, the legal representative of the transferor or of the
custodian, an adult member of the minor's family or any other interested person may
petition the court to designate a successor custodian.
E. A custodian who declines to serve under Subsection A of this section or resigns
under Subsection C of this section or the legal representative of a deceased or
incapacitated custodian as soon as practicable, shall put the custodial property and
records in the possession and control of the successor custodian. The successor
custodian by action may enforce the obligation to deliver custodial property and records
and becomes responsible for each item as received.
F. A transferor, the legal representative of a transferor, an adult member of the
minor's family, a guardian of the person of the minor, the conservator of the minor or the
minor if the minor has attained the age of fourteen years may petition the court to
remove the custodian for cause and to designate a successor custodian other than a
transferor under Section 5 [96-7-15 NMSA 1978] of the Uniform Transfers to Minors Act
or to require the custodian to give appropriate bond.
