New Mexico mechanic's liens

Who and what this applies to

Private mechanics’ and materialmen’s lien notice, filing and enforcement requirements.

Thresholds and scope

The over-$5,000 preliminary-notice rule excludes ≤4-unit residences, original contractors and parties directly contracting with the original contractor.

The rules

• Covered claimants give written notice within 60 days of first furnishing to the owner/reputed owner or original contractor by the statutory methods. Late notice protects only furnishing from 30 days before notice onward; the statute also conditions a no-notice defense on provision of requested identifying information. Source
• Original contractors record within 120 days after contract completion; others within 90 days after the statutory building/improvement/alteration/repair completion or mining-labor trigger. The verified claim must identify the demand, parties, contract terms and property. Source
• Send/deliver the filed claim copy to the known owner/reputed owner within 15 days, using the statutory address and mail/email/certified-mail/hand-delivery options. Failure may bar interest, fees or costs. Source
• Commence court proceedings or binding arbitration within two years after filing. A contingent-payment contract clause does not waive filing/enforcement rights. Source
