N.M. Stat. § 45-3-204
Demand for notice of order or filing concerning
decedent's estate.
Any interested person desiring notice of any order or filing pertaining to a decedent's
estate may at any time after the death of the decedent file a demand for notice with the
clerk of the court in which the proceedings for the decedent's estate are being
conducted or in the district court of the county where they would be pending if
commenced. A person commencing a proceeding for a decedent's estate in probate
court shall inquire of the clerk of the district court for that county whether any demand
for notice has been filed prior to commencing a proceeding in the probate court. The
demand for notice shall state the name of the decedent, the nature of the demandant's
interest in the estate and the demandant's address or that of his attorney. The clerk
shall mail a copy of the demand to the personal representative if one has been
appointed. After filing of a demand, no order or filing to which the demand relates shall
be made or accepted without notice as prescribed in Section 45-1-401 NMSA 1978 to
the demandant or his attorney. The validity of an order which is issued, or filing which is
accepted, without compliance with this requirement shall not be affected by the error,
but the applicant or petitioner receiving the order or the person making the filing may be
liable for any damage caused by the absence of notice. The requirement of notice
arising from a demand under this provision may be waived in writing by the demandant
and shall cease upon the termination of his interest in the estate.
