A residential lease in New Mexico has a maximum duration of one (1) year. Longer leases are allowed, but they must be in writing.
Oral leases are enforceable in New Mexico for shorter durations, even if the law requires a written lease to be presented to the tenant (NM Stat § 47-8-20(G) (2019)). However, it is recommended that all leases be in writing regardless of duration.
If there is no fixed term specified in the lease agreement, the tenancy is determined to be month-to-month (unless rent is paid weekly, and then it is week-to-week) (NM Stat § 47-8-15(C) (2019)).
