N.M. Stat. § 46A-11-1103
Severability.
If any provision of the Uniform Trust Code [46A-1-101 NMSA 1978] or its application
to any person or circumstances is held invalid, the invalidity does not affect other
provisions or applications of that code which can be given effect without the invalid
provision or application, and to this end the provisions of the code are severable.
