N.M. Stat. § 45-3-405
Formal testacy proceedings; uncontested cases; hearings
and proof.
A. If a petition in a formal testacy proceeding is unopposed, the district court may
order probate or intestacy on the strength of the pleadings if satisfied that the conditions
of Section 3-409 [45-3-409 NMSA 1978] have been met, or conduct a hearing in open
court and require proof of the matters necessary to support the order requested.
B. If evidence concerning execution of a will which is not self-proved is necessary in
uncontested cases, the affidavit or testimony of at least one of the attesting witnesses is
required if he is within New Mexico, competent and able to testify. Otherwise, due
execution of a will may be proved by other evidence.
C. If the will is self-proved in an uncontested case, compliance with signature
requirements for execution is conclusively presumed and other requirements of
execution are presumed, subject to rebuttal without the testimony of any witness, upon
filing the will and the acknowledgment and affidavits annexed or attached thereto,
unless there is proof of fraud or forgery affecting the acknowledgment or affidavit.
