N.M. Stat. § 59A-18-11
Representation in application.
A. The insured shall not be bound by any statement made in an application for a
policy unless a copy of such application is attached to or endorsed on the policy when
issued as a part thereof. If any such policy delivered or issued for delivery to any person
in this state shall be reinstated or renewed and the insured or the beneficiary or
assignee of such policy shall make written request to the insurance company for a copy
of the application, if any, for such reinstatement or renewal, the insurance company
shall within fifteen days after the receipts of such request at its home office or any
branch office of the insurance company, deliver or mail to the person making such
request, a copy of such application. If such copy shall not be so delivered or mailed, the
insurance company shall be precluded from introducing such application as evidence in
any action or proceeding based upon or involving such policy or its reinstatement or
renewal.
B. No alteration of any written application for any such policy shall be made by any
person other than the applicant without his written consent, except that insertions may
be made by the insurance company, for administrative purposes only, in such manner
as to indicate clearly that such insertions are not to be ascribed to the applicant.
C. The falsity of any statement in the application for any policy covered by this Code
may not bar the right to recovery thereunder unless such false statement materially
affected either the acceptance of the risk or hazard assumed by the insurance
company.
