N.M. Admin. Code § 19.2.2.57 - LEASE ASSIGNMENTS MUST BE APPROVED BY COMMISSIONER
The lessee may assign a mineral lease, in whole or in part, only if the commissioner approves the assignment. No purported assignment will bind the state of New Mexico, or change the lessee of record, unless approved in writing by the commissioner. Provided, however, that a mere change in the name of the mineral lessee will not constitute an assignment requiring approval by the commissioner. The lessee shall promptly notify the commissioner, in writing, of any change in name or mailing address.
State regulations are updated quarterly; we currently have two versions available. Below is a comparison between our most recent version and the prior quarterly release. More comparison features will be added as we have more versions to compare.
