N.M. Stat. § 45-2-509
Revival of revoked will.
A. If a subsequent will that wholly revoked a previous will is thereafter revoked by a
revocatory act pursuant to Paragraph (2) of Subsection A of Section 45-2-507 NMSA
1978, the previous will remains revoked unless it is revived. The previous will is revived
if it is evident from the circumstances of the revocation of the subsequent will or from
the testator's contemporary or subsequent written declarations that the testator intended
the previous will to take effect as executed.
B. If a subsequent will that partly revoked a previous will is thereafter revoked by a
revocatory act pursuant to Paragraph (2) of Subsection A of Section 45-2-507 NMSA
1978, a revoked part of the previous will is revived unless it is evident from the
circumstances of the revocation of the subsequent will or from the testator's
contemporary or subsequent written declarations that the testator did not intend the
revoked part to take effect as executed.
C. If a subsequent will that revoked a previous will in whole or in part is thereafter
revoked by another, later, will, the previous will remains revoked in whole or in part
unless it or its revoked part is revived. The previous will or its revoked part is revived to
the extent it appears from the terms of the later will that the testator intended the
previous will to take effect.
