N.M. Stat. § 48-10-20
Except as otherwise provided in this section, a deed of trust, notice of resignation of trustee, assignment of a beneficial interest in a deed of trust, notice of sale, cancellation of notice of sale, trustee's deed, release of deed of trust and any instrument by which a deed of trust is subordinated or waived as to priority, if acknowledged as provided by law, shall from the time of being recorded impart notice of the content to all persons, including subsequent purchasers, mortgagees and encumbrancers for value. The recording of an assignment of the beneficial interest in a deed of trust shall not be deemed notice of the assignment to the trustor or the trustee so as to make ineffective any payment made by the trustor or received by the trustee or to preclude the application of proper credit for the payment and shall not be deemed notice to the trustor or the trustee for any other purpose. Such assigned beneficial interest is not entitled to recognition by the trustor or the trustee until actual notice of the assignment is given to the trustor or the trustee.
