N.M. Stat. § 45-2-1105
Power to disclaim; general requirements; when
irrevocable.
A. A person may disclaim, in whole or part, any interest in or power over property,
including a power of appointment. A person may disclaim the interest or power even if
its creator imposed a spendthrift provision or similar restriction on transfer or a
restriction or limitation on the right to disclaim.
B. Except to the extent a fiduciary's right to disclaim is expressly restricted or limited
by another statute of this state or by the instrument creating the fiduciary relationship, a
fiduciary may disclaim, in whole or part, any interest in or power over property, including
a power of appointment, whether acting in a personal or representative capacity. A
fiduciary may disclaim the interest or power even if its creator imposed a spendthrift
provision or similar restriction on transfer or a restriction or limitation on the right to
disclaim, or an instrument other than the instrument that created the fiduciary
relationship imposed a restriction or limitation on the right to disclaim.
C. To be effective, a disclaimer must be in a writing or other record, declare the
disclaimer, describe the interest or power disclaimed, be signed by the person making
the disclaimer, and be delivered or filed in the manner provided in Section 12 [45-2-
1112 NMSA 1978] of the Uniform Disclaimer of Property Interests Act. As used in this
subsection, "record" means information that is inscribed on a tangible medium or that is
stored in an electronic or other medium and is retrievable in perceivable form.
D. A partial disclaimer may be expressed as a fraction, percentage, monetary
amount, term of years, limitation of a power or any other interest or estate in the
property.
E. A disclaimer becomes irrevocable when it is delivered or filed pursuant to Section
12 of the Uniform Disclaimer of Property Interests Act or when it becomes effective as
provided in Sections 6 through 11 of that act [45-2-1106 to 45-2-1111 NMSA 1978],
whichever occurs later.
F. A disclaimer made under the Uniform Disclaimer of Property Interests Act is not a
transfer, assignment or release.
