How to file a mechanics lien in New Mexico

Step by step

14 steps for a subcontractor in New Mexico.

1. 1

   Step 1: Confirm your contractor's license is active before you start

   Before your first day, and it has to stay current through the whole job.

   New Mexico ties lien rights to licensing. If the work you are doing requires a Construction Industries Licensing Act license and you do not hold one, you have no lien - no matter how good your paperwork is afterward.

   Where it goes

   Construction Industries Division, New Mexico Regulation and Licensing Department (https://www.rld.nm.gov/construction/) - it has a public contractor lookup.

   How

   Nothing to file. Check your license status and make sure the classification on it actually covers the scope you contracted for.

   Proof to keep

   Your license number and a copy of the license certificate covering the entire period you were on the job. You will have to plead and prove licensure later.

   If you miss it: You have no lien. NMSA 60-13-30(B): a contractor operating without a required license "shall have no right to file or claim any mechanic's lien." And 60-13-30(A) also blocks you from suing for the money unless you allege and prove you were licensed when the claim arose. There is no cure for this after the fact.

   N.M. Stat. Ann. 60-13-30(A), (B)(opens the statute in a new tab)
2. 2

   Step 2: Walk the site and look for a posted notice of non-responsibility

   On your first day. The owner or landlord only gets three days from learning about the work to post one, so it will be up early or not at all.

   New Mexico presumes that work done with the owner's knowledge was done at the owner's request, so the owner's interest is on the hook. But an owner - or anyone else claiming an interest, like a landlord when your customer is the tenant - can take their interest out of the lien by posting a written notice that they will not be responsible for the work. This is the single most common reason a tenant-improvement lien fails to reach the building.

   Where it goes

   The notice has to be posted in a conspicuous place on the land, or on the building or improvement itself.

   How

   Nothing to file. Photograph the site on day one, including any posted signage, and photograph it again if you see a notice go up.

   Proof to keep

   Dated photos of the site at the start of work showing whether a notice was posted, and the name of the party you actually contracted with.

   If you miss it: Nothing you file is affected, but if a notice was posted your lien does not reach that person's interest. On tenant work that usually means you can lien the tenant's leasehold and not the landlord's ownership of the building - which is often worth nothing.

   N.M. Stat. Ann. 48-2-11(opens the statute in a new tab)
3. 3

   Step 3: New Mexico public job: send written notice to the prime within 90 days of your last day

   Within 90 days from the date you last performed labor or last furnished materials. This is only for claimants who have no direct contract with the prime contractor - if you contracted with the prime, you can sue on the bond without this notice.

   There is no lien on public property in New Mexico. On a state or local construction contract over $25,000 the agency must require a payment bond for 100 percent of the contract price, and that bond is your security instead of the land.

   Where it goes

   The prime contractor on the public contract.

   How

   Registered mail, postage prepaid, to the prime contractor's office, place of business or residence - or served any way a civil summons may lawfully be served.

   Proof to keep

   The registered mail receipt, a copy of the notice, and delivery tickets or daily reports fixing your true last day. Also ask the agency in writing for a certified copy of the payment bond.

   What the document must contain

   • The amount claimed, stated with substantial accuracy
   • The name of the party to whom the materials were furnished or supplied, or for whom the labor was done or performed

   If you miss it: No bond claim. And there was never a lien to fall back on, because public property cannot be liened in New Mexico.

   N.M. Stat. Ann. 13-4-18; 13-4-19(B)(opens the statute in a new tab)
4. 4

   Step 4: New Mexico public job: sue on the bond within one year after final settlement

   No suit may be commenced after one year from the date of final settlement of the contract. The statute defines final settlement as the date set by the obligee in the final closing and settlement of payment - so it is a date the public agency fixes, not a date you can calculate. Ask the agency for it in writing.

   The bond claim itself. It is filed in the name of the state for the use of the person suing.

   Where it goes

   The district court for the county where the contract was to be performed and executed, or where the claimant resides.

   How

   File suit in district court.

   Proof to keep

   The agency's written statement of the final settlement date, and the file-stamped complaint.

   If you miss it: The bond claim is time-barred. Do not guess at the final settlement date - if you cannot get it from the agency, file early rather than late.

   N.M. Stat. Ann. 13-4-19(D)(opens the statute in a new tab)
5. 5

   Step 5: Federal job: send Miller Act notice to the prime within 90 days of your last day

   Within 90 days from the day you last performed labor or last supplied material. Only required if you have no direct contract with the prime contractor. If you do have a direct contract with the prime, you may sue on the bond 90 days after your last work without sending any notice.

   Kirtland AFB, White Sands, Los Alamos and any other federal site. No state lien and no state bond claim - the federal Miller Act payment bond is the whole remedy.

   Where it goes

   The prime contractor on the federal contract.

   How

   Any means that provides written, third-party verification of delivery to the prime at its office, place of business or residence - or served any way a United States marshal may serve a summons.

   Proof to keep

   The delivery verification, a copy of the notice, and records fixing your last day of labor or last delivery.

   What the document must contain

   • The amount claimed, stated with substantial accuracy
   • The name of the party to whom the material was furnished or supplied, or for whom the labor was done or performed

   If you miss it: No bond claim. Federal property cannot be liened.

   40 U.S.C. 3133(b)(1), (b)(2) (Miller Act)(opens the statute in a new tab)
6. 6

   Step 6: Federal job: sue on the bond within one year of your last day

   No later than one year after the day on which you last performed labor or last supplied material. Note this runs from your own last day, not from any settlement date.

   The civil action on the Miller Act payment bond.

   Where it goes

   United States district court for the district where the contract was to be performed and executed.

   How

   File a civil action on the payment bond.

   Proof to keep

   Delivery tickets, signed daily reports or payroll records fixing your last day, and the file-stamped complaint.

   If you miss it: The bond claim is time-barred.

   40 U.S.C. 3133(b)(4) (Miller Act)(opens the statute in a new tab)
7. 7

   Step 7: Ask the owner or general contractor for the project facts in writing

   Optional

   Early in the job, before you send any pre-lien notice.

   Two things at once. First, you need the exact owner name and a property description to put in your notices and in the lien, and getting those wrong is what makes liens fail later. Second, if the owner or the general contractor later defends by saying they never got your pre-lien notice, they have to show that they answered your request within five days - so making the request in writing creates that record for you.

   Where it goes

   The property owner, or the original contractor (the one who contracted directly with the owner).

   How

   A written request to the owner or to the original contractor. On a residential site of four or fewer dwelling units, NMSA 48-2A-4 separately requires the original contractor to give subs and suppliers the owner's name and address, the construction lender and loan officer, and the legal description.

   Proof to keep

   The dated request, whatever came back, and the silence if nothing did.

   What the document must contain

   • What they must give you back within five days: the original contractor's name, address and license number, if there is one on the project
   • The owner's name and address
   • A description of the property, or a description sufficiently specific for actual identification of the property
   • The name and address of any bonding company or other surety providing a payment or performance bond for the project

   If you miss it: Nothing happens automatically. You just lose an easy way to get the owner name and legal description right, and you give up a record that would have hurt a lack-of-notice defense.

   N.M. Stat. Ann. 48-2-2.1(C); 48-2A-4(opens the statute in a new tab)
8. 8

   Step 8: House or small residential job: send the 20-day preliminary notice to the construction lender and the owner

   Optional

   Within 20 days after you first furnish work or materials to the site. Only on a residential site of no more than four dwelling units - that is the only kind of project where the Stop Notice Act exists.

   This is not a lien notice and your lien does not depend on it. It is the ticket to the Stop Notice Act, which lets you make a claim against the construction lender's undisbursed loan money instead of against the property. On a small residential job that matters a lot, because the owner's payment can wipe out an unrecorded lien.

   Where it goes

   Both the construction lender and the owner. Not one or the other.

   How

   To the construction lender: hand delivery, or mail with return receipt requested, to the manager or other responsible person at the address where the construction loan originated - or the lender's last known address if that address has changed. To the owner: hand delivery, or mail with return receipt requested, to the owner's last known residential or business address.

   Proof to keep

   Return receipts from both recipients, a copy of the notice, and a delivery ticket or daily report fixing your first furnishing date.

   If you miss it: Your lien rights are untouched. You lose stop notice rights for everything you furnished more than 20 days before you actually send the notice. You may still send it late - it just cuts the claim down to the trailing 20 days and everything after.

   N.M. Stat. Ann. 48-2A-5(B), (C); 48-2A-6(A)(opens the statute in a new tab)
9. 9

   Step 9: Serve the pre-lien Notice of Right to Claim a Lien within 60 days of your first day

   Within 60 days after you first furnish work or materials. You only need it if all three of these are true: your claim will be more than $5,000; you have no contract with the owner AND no contract with the original contractor (the one who signed with the owner); and the property is not residential with four or fewer dwelling units. If you signed directly with the general contractor, you are exempt.

   A written notice telling them you have the right to claim a lien if you are not paid. Without it, a lien over $5,000 cannot be enforced by action or otherwise.

   Where it goes

   The statute says the owner or reputed owner of the property, OR the original contractor if there is one. It is written as "or" - but serving both costs one extra certified letter and removes the argument.

   How

   Certified mail, return receipt requested; facsimile with acknowledgement; or personal delivery. Those are the only three methods the statute names.

   Proof to keep

   The certified mail receipt and green card, the fax acknowledgement, or a signed delivery receipt; a copy of the notice as sent; and a delivery ticket, signed daily report or invoice fixing your first furnishing date.

   What the document must contain

   • A statement in writing of your right to claim a lien in the event of nonpayment
   • A description of the property, or a description sufficiently specific for actual identification of the property
   • Your name, address and phone number, if any
   • The name and address of the person you contracted with, or to whom you furnished labor or materials

   If you miss it: You cannot enforce a lien over $5,000 for the work you already did - but this is a partial loss, not a total one. NMSA 48-2-2.1(E) lets you serve late, and the lien then covers only work performed or materials furnished on or after the date 30 days before you actually served it. So if you are late, serve today, not next week: every day you wait cuts more off the claim.

   N.M. Stat. Ann. 48-2-2.1(A), (B), (D), (E)(opens the statute in a new tab)
10. 10

    Step 10: Record your claim of lien within 90 days of completion of the building

    Within 90 days after the completion of the building, improvement or structure - or after completion of the alteration or repair. This is NOT 90 days from your own last day. If you finished your scope in March and the building was completed in April, your clock started in April. If the building was substantially finished in February while you were still doing warranty work, your clock may have started in February. The earlier of the two dates is the only one that cannot be late.

    The claim of lien is the document that creates the lien. Until it is recorded there is no lien on the property, only a debt. Some claimants who contracted directly with the owner argue they get the original contractor's 120 days. The statute does not define "original contractor" for this section and we found no New Mexico case deciding it, so work to 90.

    Where it goes

    The county clerk of the county in which the property, or some part of it, is situated. New Mexico records with the county clerk - there is no separate recorder or register of deeds. All 33 clerks are listed at https://www.sos.nm.gov/voting-and-elections/voter-information-portal-nmvote-org/county-clerk-information/.

    How

    File it for record with the county clerk. It must be verified by the oath of the claimant or of some other person - somebody swears to it in front of a notary. It also has to be acknowledged (notarized) to be recordable at all. Recording is $25 per document covering up to ten entries in the county recording index, plus another $25 for each additional block of ten or fewer entries.

    Proof to keep

    The clerk-stamped recorded copy with its instrument or recording number and the recording date - you will need that date for the two-year enforcement clock. Keep the fee receipt, and whatever fixes the completion date: certificate of occupancy, final inspection, architect's certificate, or the general contractor's own close-out paperwork.

    What the document must contain

    • A statement of your demands, after deducting all just credits and offsets
    • The name of the owner or reputed owner, if known
    • The name of the person by whom you were employed, or to whom you furnished the materials
    • A statement of the terms, time given and conditions of the contract
    • A description of the property to be charged with the lien, sufficient for identification
    • Verification by the oath of the claimant or of some other person

    If you miss it: No lien. The deadline does not extend and there is no grace period. You still have an ordinary lawsuit against whoever owes you the money, but nothing against the property.

    N.M. Stat. Ann. 48-2-6(A)(opens the statute in a new tab)
11. 11

    Step 11: Send the owner a copy of the recorded lien within 15 days

    Within 15 days of filing the claim with the county clerk. Do it the same day you record and the deadline takes care of itself.

    A requirement added in 2023 and easy to miss if you learned New Mexico lien practice before then. Recording alone is no longer the end of the job.

    Where it goes

    The owner or reputed owner named in your claim, at that owner's last known address. If you do not know the address, send it to the address of the owner of the property as listed in the county assessor's files.

    How

    Mail it, email it, send it by certified mail with return receipt requested, or hand deliver it. Any of the four works.

    Proof to keep

    The certified mail receipt and green card, the sent email with the recorded copy attached, or a signed hand-delivery receipt. If the address was unknown, keep a printout of the county assessor's record you used.

    What the document must contain

    • A copy of the claim for lien as filed with the county clerk

    If you miss it: The lien itself survives. But NMSA 48-2-6(B) says failing to serve "may preclude the recovery of interest, attorney's fees or costs." In a lien fight those three routinely cost more than the principal you are chasing.

    N.M. Stat. Ann. 48-2-6(B)(opens the statute in a new tab)
12. 12

    Step 12: House or small residential job: deliver a stop notice 20 to 30 days after you asked the contractor for payment

    Optional

    No earlier than 20 days and no later than 30 days from the date you presented your request for payment to the original contractor. You must already have sent the 20-day preliminary notice.

    A stop notice reaches the construction lender's undisbursed loan money instead of the property. It is powerful and it is expensive, and it carries a trap: see the next step before you use it.

    Where it goes

    The construction lender. If there is no construction lender, the owner.

    How

    Signed and verified by you or your agent. It is not effective unless it is accompanied by a bond equal to 1.25 times the amount claimed - or by cash collateral of 1.25 times the claim posted with the recipient. The bond protects the owner, the original contractor and the lender against damages caused by the stop notice.

    Proof to keep

    A date-stamped copy of the payment request you sent the original contractor, the bond or the collateral receipt, the stop notice itself, and proof of delivery.

    What the document must contain

    • Your name
    • The date you filed the preliminary notice
    • The date you presented your request for payment to the original contractor
    • The name of the owner and of the original contractor for the residential site
    • A description of the kind of labor or materials furnished or agreed to be furnished
    • The name of the person who ordered the labor or accepted the materials
    • The total cost of all labor or materials to be furnished to the site
    • The cost of the labor or materials already furnished
    • The balance of the money due
    • A demand that the construction lender, or the owner if there is no lender, withhold a sufficient amount
    • A bond for 1.25 times the claim, or cash collateral in the same amount

    If you miss it: You lose the stop notice. Your mechanics lien is unaffected - and for most claimants the lien is the cheaper route anyway, because the stop notice costs you a 1.25x bond up front.

    N.M. Stat. Ann. 48-2A-5(A), (D); 48-2A-7(opens the statute in a new tab)
13. 13

    Step 13: If you delivered a stop notice, sue on it between 30 and 60 days after delivery

    Optional

    Not earlier than 30 days and not later than 60 days after you delivered the stop notice. Read the warning below before you start down this road at all.

    Here is the trap. While that stop notice suit is being litigated, you may not file a lien for the money the stop notice claims - and your 90-day lien clock keeps running the whole time. Pursuing a stop notice can run your lien deadline out from under you. If both routes are open, record the lien first.

    Where it goes

    A court of competent jurisdiction.

    How

    File suit for satisfaction of the stop notice.

    Proof to keep

    Proof of the delivery date of the stop notice (that date starts both ends of the window), and the file-stamped complaint.

    If you miss it: The stop notice dies. And you spent the intervening weeks barred from filing a lien for the same money while the 90-day lien clock ran.

    N.M. Stat. Ann. 48-2A-9(A), (B)(opens the statute in a new tab)
14. 14

    Step 14: Start enforcement within two years of the day you recorded the lien

    Two years from the date the claim of lien was filed with the county clerk. Not from completion. Not from your last day. From the recording date on the stamp. The statute says two years, so count calendar years, not 730 days.

    The lien simply stops being valid at two years unless you have commenced proceedings to enforce it. Nothing tolls it - not negotiations, not a payment plan, not a promise from the general contractor.

    Where it goes

    District court for the county where the property is, or the arbitration forum your contract names.

    How

    Commence proceedings in a court of competent jurisdiction, OR commence binding arbitration. The statute accepts either, so if your contract sends you to arbitration you are not required to file suit as well. A demand letter is not commencing proceedings.

    Proof to keep

    The file-stamped complaint, or the arbitration demand together with proof of the date it was filed or served on the arbitration provider.

    If you miss it: The lien is gone. You still have a personal action for the debt against whoever owes it, subject to its own limitation period - but the claim against the property is over, and so is any claim against security that was deposited to bond the lien off.

What trips people up in New Mexico

• Using the general contractor's 120 days when you are a sub or a supplier. Only a contractor in direct contract with the owner gets 120 days. Everyone else gets 90.
• Counting the 90 days from your own last day on site. The statute keys it to completion of the building, improvement or structure - not to your scope. A sub who finished early and then waits 90 days from their own last day can be months late. New Mexico practitioners read "completion" as substantial completion, which is earlier than final acceptance and earlier than most claimants assume. We could not find a New Mexico case construing the word in this statute, which is another reason to use the earlier date.
• Recording a claim of lien that is not sworn. NMSA 48-2-6(A): "The claim shall be verified by the oath of the claimant or of some other person." A perfectly timed, perfectly accurate, unsworn document is worth nothing. Get it notarized as a sworn statement, not just signed.
• Working without the license the job required. NMSA 60-13-30(B) removes lien rights entirely, and 60-13-30(A) blocks the collection suit too unless you plead and prove you were licensed when the claim arose. There is no fix after the fact.
• On a house or small residential job, waiting out the 90 days while the owner pays or the property sells. NMSA 48-2A-11(A) discharges these liens the moment the owner or a successor in interest pays what is due - unless you already recorded. On a four-unit-or-fewer residential site your real deadline is before the money moves or the sale closes, not the 90th day.
• Missing the 60-day pre-lien notice and then giving up. NMSA 48-2-2.1(E) lets you serve it late; the lien then reaches work and materials from 30 days before the notice onward. Walking away forfeits money that is still there.
• Sending the 60-day notice when you did not need it, or skipping it when you did. It applies only when the claim exceeds $5,000 AND you have no contract with the owner AND no contract with the original contractor AND the property is not residential with four or fewer dwelling units. A first-tier sub working directly for the GC is exempt. A sub-sub or a supplier to a sub is not. Sending one you did not need costs a stamp; skipping one you did costs the lien.
• Chasing a stop notice and losing the lien. You cannot file a lien for money claimed by a stop notice while the stop notice suit is pending (NMSA 48-2A-9(B)), that suit must be filed 30 to 60 days after delivery, and your 90-day lien clock never pauses. Also, the stop notice is dead on arrival without a bond or cash collateral of 1.25 times the claim.
• Working for a tenant and assuming you can lien the building. NMSA 48-2-11 lets the landlord post a written notice of non-responsibility, conspicuously on the property, within three days of learning about the work - and that takes their interest out of your lien. Photograph the site on day one.
• Filing a lien on a public job. No lien attaches to public property in New Mexico. Recording one accomplishes nothing and the 90-day bond notice window keeps running while you think you are protected.
• Recording the lien and stopping there. Since 16 June 2023 a copy has to reach the owner within 15 days of filing (NMSA 48-2-6(B)). Skipping it can cost you interest, attorney's fees and costs on a lien you otherwise win.
• Treating the two-year enforcement window as comfortable. It runs from the recording date, not from completion, and nothing tolls it. Binding arbitration commenced in time counts; a demand letter does not.
• Letting a pay-if-paid clause talk you out of filing. NMSA 48-2-10 says a contingent payment clause in a contract shall not be construed as a waiver of the right to file and enforce a lien.
• Expecting to collect more than the owner still owes upstream. NMSA 48-2-12 lets the owner withhold and deduct, and NMSA 48-2-13 puts original contractors last in line at foreclosure, behind subcontractors and behind everyone else.
• Forgetting the fee shift cuts both ways. NMSA 48-2-14 awards reasonable attorney fees, costs and expenses to the prevailing party - which can be the owner who defeats your lien.

After you file

• Serve the owner a copy of the recorded lien within 15 days. This is the second forfeiture point in New Mexico and it is brand new relative to most lien training. The lien survives if you skip it, but interest, attorney's fees and costs may not (NMSA 48-2-6(B)).
• Expect the owner or the general contractor to bond it off. Either of them can petition the district court under NMSA 48-2-9; the judge sets an amount sufficient to cover your recorded demands plus damages, costs and fees, they deposit security, and the clerk marks your lien cancelled. Your lien then attaches to the security instead of the land and is enforceable against it to the same extent. This is not a loss - the security is often better collateral than the property. But your two-year clock keeps running against it, unchanged.
• Expect pressure to land on your general contractor. Under NMSA 48-2-12 the owner may withhold from the contractor the amount of your filed lien, and may deduct any judgment from what is owed to the contractor. The exception: the owner may not withhold if the lien exists because the owner failed to pay the contractor in the first place. That withholding mechanism is why most of these get paid without a foreclosure.
• Understand what you can actually collect. NMSA 48-2-12 caps the contractor's own lien recovery at what remains after subcontractor liens are deducted. At foreclosure, NMSA 48-2-13 pays everyone other than original contractors and subcontractors first, then subcontractors, then original contractors - pro rata within each class. If you are the general contractor, you are last in line.
• Attorney fees run both ways. NMSA 48-2-14 gives the prevailing party in a dispute arising out of or relating to a lien action its reasonable attorney fees, costs and expenses from the other party. If your lien is thrown out, you can be the one writing the check.
• On a residential site of four or fewer dwelling units, recording is what protects you. NMSA 48-2A-11(A) discharges these liens when the owner or a successor in interest pays the amounts due - but only as to claimants who had not already recorded. Once you are recorded, that discharge does not reach you.
• Nobody can shorten your two-year window. We found no notice of completion, no notice of contest, and no owner's demand that you commence suit anywhere in NMSA Chapter 48, Article 2. Bonding the lien off under 48-2-9 does not accelerate the deadline either. The two years from recording is the deadline, and it is yours.
• When you are paid, record a release with the same county clerk so the title clears. We could not source a New Mexico deadline or penalty for failing to release a satisfied lien.
