N.M. Stat. § 45-5A-106
Taking testimony in another state.
A. In a guardianship or protective proceeding, in addition to other procedures that
may be available, testimony of a witness who is located in another state may be offered
by deposition or other means allowable in New Mexico for testimony taken in another
state. The court on its own motion may order that the testimony of a witness be taken in
another state and may prescribe the manner in which, and the terms upon which, the
testimony is to be taken.
B. In a guardianship or protective proceeding, a New Mexico court may permit a
witness located in another state to be deposed or to testify by telephone or audiovisual
or other electronic means. A New Mexico court shall cooperate with the court of the
other state in designating an appropriate location for the deposition or testimony.
C. Except as otherwise provided by rules adopted by the New Mexico supreme
court, documentary evidence transmitted from another state to a New Mexico court by
technological means that do not produce an original writing shall not be excluded from
evidence on an objection based on the best evidence rule.
