N.M. Stat. § 45-3-1008
Subsequent administration.
If other property of the estate is discovered after an estate has been settled and the
personal representative discharged, or after one year after a closing statement has
been filed, the district court, upon petition of any interested person and upon notice as it
directs, may appoint the same or a successor personal representative to administer the
subsequently discovered estate. If a new appointment is made, unless the district court
orders otherwise, the provisions of the [Uniform] Probate Code apply as appropriate.
However, no claim previously barred may be asserted in the subsequent administration.
