N.M. Stat. § 45-5-430
Termination of proceeding.
The protected person, his personal representative, the conservator or any other
person interested in the welfare of a person for whom a conservator has been
appointed may petition the court to terminate the conservatorship. A protected person
seeking termination is entitled to the same rights and procedures as in an original
proceeding for a protective order. The court, upon finding after notice and hearing that
the minority or disability of the protected person has ceased, may terminate the
conservatorship. Upon termination, title to assets of the estate passes to the former
protected person or to his successors, subject to provision in the order for expenses of
administration or to conveyances from the conservator to the former protected person or
his successors, to evidence the transfer.
