Prime Contractor
Preliminary Notice: Not required. The original contractor is expressly exempt from the Notice of Right to Claim a Lien.
Mechanic Lien: Record the claim of lien with the county clerk within 120 days after completion of the contract. The clock runs from completion of the original contractor's own contract, not from the last day on site. Send a copy of the filed claim to the owner or reputed owner within 15 days of filing, by mail, email, certified mail with return receipt requested, or hand delivery.

Enforcement: Commence proceedings to enforce the lien within 2 years after the claim of lien is filed. The clock runs from the filing date, not from completion or last furnishing. Either a court action or binding arbitration commences the proceeding, so a contract with an arbitration clause does not force a protective lawsuit. Nothing has to be recorded to give notice that the proceeding is pending.
Subcontractors & Suppliers
Preliminary Notice: Not required. A mechanic or materialman who contracts directly with the original contractor is exempt, whatever the size of the claim. Where the tier is arguable, sending the notice anyway is not required but removes the question. A supplier who sells to the original contractor is exempt; a supplier who sells to a subcontractor is not.
Mechanic Lien: Record the claim of lien with the county clerk within 90 days after completion of the building, improvement, or structure, or after completion of the alteration or repair. This is a project event, not the claimant's own last day of furnishing. Send a copy of the filed claim to the owner or reputed owner within 15 days of filing, by mail, email, certified mail with return receipt requested, or hand delivery. If the owner's address is not known, use the address for the property in the county assessor's files. Missing this does not void the lien, but it can cost interest, attorney fees, and costs. Because the clock runs from an event the claimant does not control, pin the completion date down with documents rather than counting from the last invoice. A claimant that finished early can sit well inside the window while the job runs on, and one that assumes its own last day started the clock can file late.
Enforcement: Commence proceedings to enforce the lien within 2 years after the claim of lien is filed. The clock runs from the filing date, not from completion or last furnishing. Either a court action or binding arbitration commences the proceeding, so a contract with an arbitration clause does not force a protective lawsuit. Nothing has to be recorded to give notice that the proceeding is pending.
Remote Claimants
Preliminary Notice: Give written notice within 60 days after first furnishing work or materials. This tier has no exemption: a sub-subcontractor, or a supplier selling to a subcontractor, contracts with neither the owner nor the original contractor and owes the notice. It bites only where the lien claim exceeds $5,000. At or below that figure no notice is required. Measure against the claim the lien will assert, not the base contract price, because change orders and extras can carry a small contract past the threshold. Serve it on the owner or reputed owner, or on the original contractor, by certified mail with return receipt requested, by fax with acknowledgment, or by personal delivery. It is served, not recorded. It has to describe the property, identify the claimant with an address and telephone number, and name the party the claimant contracted with. A late notice is not a dead notice. It still reaches work performed and materials furnished on or after the date 30 days before it is given, so everything earlier drops out of the lien. Serve it at contract signing and the question never comes up. This is a condition of enforcement. A covered lien over $5,000 cannot be enforced without it.

New Mexico private project deadlines — Residential, 4 or Fewer Units
Prime Contractor
Preliminary Notice: Not required. The original contractor is expressly exempt from the Notice of Right to Claim a Lien. No preliminary notice is required of the original contractor, but the disclosure duty runs the other way on this work: before contracting with a subcontractor or materialman it has to give them the owner's name and address, the construction lender's name and address and the loan officer who made the loan, and a description of the residential site.
Mechanic Lien: Record the claim of lien with the county clerk within 120 days after completion of the contract.

Subcontractors & Suppliers
Preliminary Notice: The Notice of Right to Claim a Lien does not reach residential property containing four or fewer dwelling units. Recording the lien on this work does not depend on any preliminary notice. To preserve stop notice rights against the construction funds, deliver a preliminary notice to the construction lender and to the owner within 20 days after first furnishing. It goes to the lender, hand-delivered or mailed with return receipt requested to the address where the construction loan originated, and to the owner, hand-delivered or mailed with return receipt requested. A late preliminary notice does not end stop notice rights, but it drops everything furnished more than 20 days before the notice actually goes out. The stop notice itself is delivered 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. It is not effective without a bond, or cash collateral, equal to one and one quarter times the amount claimed. A stop notice is a claim against the construction funds, not against the property, and it is not a prerequisite to a lien. On receipt the construction lender, or the owner where there is no lender, withholds the amount claimed from the original contractor until the claim is satisfied or adjudicated.

Suit to satisfy it is filed no earlier than 30 days and no later than 60 days after the stop notice is delivered, with written notice of the suit mailed to the recipient within 5 days after filing. While that suit is pending the claimant may not file a lien for the same money, so the two remedies have to be sequenced rather than run in parallel.
Remote Claimants
Preliminary Notice: The Notice of Right to Claim a Lien does not reach residential property containing four or fewer dwelling units. Recording the lien on this work does not depend on any preliminary notice. To preserve stop notice rights against the construction funds, deliver a preliminary notice to the construction lender and to the owner within 20 days after first furnishing. A materialman supplying a subcontractor is covered; a supplier selling to another supplier is outside the act. A late preliminary notice does not end stop notice rights, but it drops everything furnished more than 20 days before the notice actually goes out. A subcontractor asked for the owner's name and address, the construction lender's details, and the legal description of the site has to provide them. Ask in writing at the start of the job, because a stop notice cannot be addressed without them. The stop notice itself is delivered 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. It is not effective without a bond, or cash collateral, equal to one and one quarter times the amount claimed. A stop notice is a claim against the construction funds, not against the property, and it is not a prerequisite to a lien.

New Mexico Mechanic Lien Law Overview
Last updated April 2026 · Reviewed by Thomas Emalfarb, Esq.
New Mexico construction mechanic lien rights are governed by N.M. Statutes §48-2-1 et seq. for general mechanic's liens and §48-2A-1 et seq. for the residential stop notice. This statutory framework provides Mechanic's Lien rights to contractors, subcontractors, and material suppliers who furnish labor or materials for the improvement of real property in the State of New Mexico.
New Mexico has different requirements for contractors and subcontractors. Contractors are not required to serve any preliminary notice and must record a Mechanic Lien Claim within 120 days after completion of the contract. Everyone else records within 90 days after completion of the building, improvement, or structure. Under §48-2-2.1, a mechanic or materialman who contracts with neither the owner nor the original contractor must serve a Notice of Right to Claim a Mechanic Lien within 60 days of first furnishing where the lien claim exceeds $5,000. An original contractor, and anyone contracting directly with the original contractor, is exempt, and the requirement does not reach residential property containing 4 or fewer dwelling units. Every claimant must send the owner a copy of the filed claim within 15 days of filing under §48-2-6(B), or risk losing interest, attorney fees, and costs.
Residential property containing 4 or fewer dwelling units is carved out of the §48-2-2.1 notice, and the Stop Notice Act at §48-2A-1 et seq. covers that work instead. A stop notice is a claim against the construction funds rather than against the property. To preserve it, the subcontractor or materialman delivers a preliminary notice to the construction lender and the owner within 20 days after first furnishing; a late notice loses everything furnished more than 20 days before it is given. The stop notice itself is delivered 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, and it is not effective without a bond or cash collateral equal to 1.25 times the claim.
New Mexico public works projects are governed by the Little Miller Act under §13-4-19.

Frequently Asked Questions
What statute governs mechanic liens in New Mexico?
Mechanic's liens are governed by N.M. Statutes §48-2-1 et seq. The residential stop notice is under §48-2A-1 et seq. Public works payment bonds are governed by the Little Miller Act under §13-4-19.
Is a preliminary notice required to file a mechanic lien in New Mexico?
Usually not. Under §48-2-2.1(A), the original contractor is exempt, anyone contracting directly with the original contractor is exempt, and residential property of 4 or fewer dwelling units is outside the requirement. It lands on the remote tier: a claimant in privity with neither the owner nor the original contractor, on a lien claim exceeding $5,000, serves the notice within 60 days of first furnishing.
What is the deadline to file a mechanic lien in New Mexico?
Under §48-2-6(A), the original contractor records within 120 days after completion of its contract; everyone else within 90 days after completion of the building, improvement, or structure. Both run from completion, not last furnishing. Every claimant sends the owner a copy of the filed claim within 15 days under §48-2-6(B).
How does New Mexico mechanic lien law differ from other states?
Several features stand out: split deadlines running from completion rather than last furnishing (120 days for the original contractor, 90 for everyone else), a narrow preliminary notice that reaches only remote claimants on claims over $5,000, a 30-day lookback that salvages part of a late notice, a separate Stop Notice Act covering residential property of 4 or fewer dwelling units, a 2-year enforcement period that binding arbitration can satisfy, and the Little Miller Act for public works.
What are the notice requirements for New Mexico public works bond claims?
Subcontractors not in privity with the contractor must serve written Notice of Claim by registered letter within 90 days after last performance under §13-4-19. Those in privity need no notice. Suit within 1 year of final settlement.
What is the deadline to file suit to enforce a New Mexico construction mechanic lien?
All claimants must file suit within 2 years after the date the mechanic lien is filed. For Little Miller Act bond claims, suit within 1 year after final settlement of the prime contract.
