New Mexico Mechanic Lien Filing Deadlines

Contractors — 120-Day Mechanic Lien Claim Filing Deadline

Under New Mexico law, contractors must record a Mechanic Lien Claim within 120 days after completion of the contract. This is the longest filing period among New Mexico claimant types. No preliminary notice is required for contractors.

The 120-day deadline is measured from completion of the contract, not from last furnishing of labor or materials. Contractors should carefully determine the contract completion date to calculate the correct filing deadline.

Subcontractors & Materialmen — 90-Day Filing Deadline

Under §48-2-6(A), every person except the original contractor must record a Mechanic Lien Claim within 90 days after completion of the building, improvement, or structure, or after completion of the alteration or repair. The clock runs from that project event, not from the claimant's last date of furnishing.

This cuts both ways. A subcontractor that finished early can sit well inside the window while the job runs on, and a subcontractor that assumes the clock started on its own last day can file late. Pin the completion date down with documents rather than counting from the last invoice.

A remote claimant on a claim exceeding $5,000 must also have served the Notice of Right to Claim a Mechanic Lien within 60 days of first furnishing under §48-2-2.1. Claimants in direct contract with the original contractor, and all claimants on residential property of 4 or fewer dwelling units, are outside that requirement.

Every Claimant — 15-Day Owner Copy After Filing

Under §48-2-6(B), added by the 2023 amendment effective June 16, 2023, a claimant who files a claim of lien with the county clerk must send a copy to the owner or reputed owner within 15 days of filing. Mail, email, certified mail with return receipt requested, and hand delivery all satisfy it.

Send it to the owner's last known address. If that address is not known, use the address for the property in the county assessor's files. Failing to serve the copy does not void the lien, but it may preclude the recovery of interest, attorney fees, and costs, which on a modest claim can exceed the claim itself.

Residential Property of 4 or Fewer Units — Stop Notice Timing

The lien deadlines above apply to residential property of 4 or fewer dwelling units the same way they apply to anything else. What changes is the additional remedy: the Stop Notice Act at §48-2A-1 et seq., which reaches the construction funds rather than the property.

Its clock is separate and much shorter. Preliminary notice to the construction lender and the owner within 20 days of first furnishing under §48-2A-5(B). The stop notice itself no earlier than 20 days and no later than 30 days from the date the claimant presented its request for payment to the original contractor, under §48-2A-5(D), bonded at 1.25 times the claim under §48-2A-7. Suit no earlier than 30 days and no later than 60 days after delivery of the stop notice, under §48-2A-9(A).

Note that §48-2A-9(B) bars filing a lien for the same money while the stop notice suit is being litigated, so the two remedies have to be sequenced rather than run in parallel.

Late Notice — 30-Day Lookback Protection

Under §48-2-2.1(E), where the Notice of Right to Claim a Mechanic Lien is given more than 60 days after first furnishing, the lien reaches only work performed and materials furnished on or after the date 30 days before the notice was given. This partial protection preserves some rights for a claimant who misses the 60-day deadline, but on a long-running job it can strip out most of the balance.
