N.M. Code R. § 1.12.7.11
A transaction is governed by a law or regulation that requires the presence of a signature before it will be considered legally effective. A state agency must review the law applicable to each proposed transaction to determine if it requires that the transaction be “signed.” If the applicable law or regulation requires a signature, then to conduct the transaction in electronic form requires an electronic signature.
