Squatters Rights in New Mexico: 10-Year Adverse Possession Law
New Mexico requires 10 years of possession under color of title with tax payment, or a much longer period (generally cited as 25 years) without them. New Mexico has also criminalized unlawful squatting, with a distinct process for law enforcement to notify and, if uncontested, remove an occupant.

How Adverse Possession Works in New Mexico
To claim ownership of property through adverse possession in New Mexico, a claimant must possess the land for 10 years while meeting the legal requirements established under state law.
Legal Basis and Statutory Period
New Mexico’s adverse possession law is codified under N.M. Stat. Ann. § 37-1-22. The standard statutory period is 10 years of continuous, open, and hostile possession.

Recent Law Changes in New Mexico
New Mexico has criminalized unlawful squatting, defined as entering and residing on another's property without the owner's knowledge or consent, with civil liability (double damages) for a squatter who damages the property. An officer must present a property owner's affidavit to the occupant at least 3 days before removal, unless the occupant provides a counter-affidavit asserting a legal right to possession. The exact bill number and enactment date should be verified directly, as available research did not isolate a single clearly-dated 2024-2025 act.
New Mexico Adverse Possession Procedures
Making an Adverse Possession Claim in New Mexico
New Mexico's adverse possession statute, NMSA 1978 § 37-1-22, sets a single 10-year period but adds a requirement not found in every state: the claimant must show they paid the property taxes assessed against the land during the statutory period.
- File a quiet title action in the district court for the county where the property is located
- Prove possession was actual, open, notorious, exclusive, hostile, and continuous for the full 10 years under NMSA § 37-1-22
- Produce tax records showing the claimant, not the record owner, paid property taxes on the parcel throughout the statutory period
- Present supporting evidence such as witness testimony, surveys, photographs, and documentation of improvements
- Address any evidence of permissive use, shared use with the public, or an interruption in possession
- Obtain a court judgment quieting title, then record it with the county clerk
As Platt v. Martinez shows, missing tax payments are fatal to a New Mexico claim even when every other element, including decades of fencing and use, is satisfied.
Defending Against Squatters and Boundary Encroachment
Because New Mexico requires proof of tax payment, property owners who keep their own tax accounts current have a real structural advantage in defeating a rival claim.
- Confirm your own property tax payments are current and keep receipts, since a claimant must show they — not you — paid taxes on the disputed land
- Inspect boundaries periodically, particularly on rural, grazing, or land-grant-adjacent parcels where shared or open range use is common
- Post the property or fence it to signal exclusive control
- Put any permitted neighbor use in writing
- Act promptly against encroachments; waiting out the 10-year period allows a claim to mature
Under Martinez v. Mundy, use that is shared with the general public, rather than exclusive to one claimant, does not qualify as adverse possession — a point that matters often in New Mexico given its many communal land grants.
Removing Squatters in New Mexico
- For a recent trespasser with no claimed right to the property, New Mexico's criminal trespass statute, NMSA § 30-14-1, allows police to act on a knowing, unauthorized entry
- For an occupant claiming residency, file an unlawful detainer action under the Uniform Owner-Resident Relations Act, NMSA §§ 47-8-1 to 47-8-52, in the district or magistrate court for the county
- Attend the hearing, and if the court rules for the owner, obtain a writ of restitution
- Have law enforcement execute the writ if the occupant does not leave voluntarily
New Mexico does not allow self-help evictions such as changing locks or removing a squatter's belongings without a court order.
Notable New Mexico Adverse Possession Cases
Platt v. Martinez (1977)
90 N.M. 323, 563 P.2d 586 (1977)
In a boundary dispute where a landowner had built fences that took in part of a neighbor's land, the New Mexico Supreme Court reversed a judgment for the fence-builder because he had never paid property taxes on the disputed strip. The court held that tax payment is a distinct, mandatory element of New Mexico adverse possession, and its absence defeats a claim no matter how strong the other evidence is.
Martinez v. Mundy (1956)
61 N.M. 87, 295 P.2d 209 (1956)
In this ejectment action over a land-grant tract, the New Mexico Supreme Court found that use shared with the general public — cutting wood, watering livestock, and using roads in common with others — was not exclusive and could not support an adverse possession or prescriptive-easement claim, while separately confirming that possession which is actual, open, continuous, notorious, and exclusive for more than ten years can support a successful claim.
Frequently Asked Questions About New Mexico Adverse Possession
How long must someone occupy my property in New Mexico to claim adverse possession?
New Mexico requires 10 years of actual, open, notorious, exclusive, hostile, and continuous possession under NMSA § 37-1-22. There is no 30-day rule — short-term occupancy never creates ownership rights.
Does a squatter have to pay my property taxes to claim adverse possession in New Mexico?
Yes, and this is one of the features that sets New Mexico apart from many states. Under NMSA § 37-1-22, as applied in Platt v. Martinez, the claimant must show they personally paid the property taxes assessed on the land during the full 10-year period. Failing to do so defeats the claim regardless of how strong the other evidence is.
Does using land in common with neighbors or the public count toward an adverse possession claim?
No. As the New Mexico Supreme Court held in Martinez v. Mundy, use that is shared with the general public — such as cutting wood, watering livestock, or using roads in common with others, patterns common on New Mexico's historic land grants — is not exclusive and cannot support an adverse possession claim.
Can someone claim adverse possession of government or land-grant trust land in New Mexico?
No. Land owned by the State of New Mexico, the federal government, or held in trust for a land grant community generally cannot be acquired through adverse possession by a private claimant.
How do I legally remove a squatter from my New Mexico property?
For a clear-cut trespasser, contact law enforcement under New Mexico's criminal trespass statute, NMSA § 30-14-1. For an occupant claiming a right to stay, you generally must file an unlawful detainer action under the Uniform Owner-Resident Relations Act in district or magistrate court and obtain a writ of restitution. Self-help evictions are not permitted.
What is "color of title" and does New Mexico require it?
Color of title is a document, such as a deed or will, that appears to convey ownership but has a legal defect. New Mexico's statute does not require color of title as a separate track with a shorter period — the 10-year period and the tax-payment requirement apply regardless of whether the claimant holds color of title.
Will the sheriff remove a squatter for me in New Mexico?
Not directly in most cases. New Mexico police can arrest someone under the criminal trespass statute, NMSA 1978 Section 30-14-1, only when the entry was knowing and unauthorized and the person has no plausible claim to be there, such as someone found freshly inside a locked, vacant home. If the occupant claims any tenancy, prior consent, or right to possession, the matter shifts to civil court: a true squatter with no landlord-tenant relationship is typically removed through a forcible entry and detainer action under NMSA 1978 Sections 35-10-1 to 35-10-11 in magistrate court, while someone claiming an actual or implied rental agreement falls under the Uniform Owner-Resident Relations Act, NMSA 1978 Sections 47-8-1 to 47-8-52. New Mexico has twice tried and failed to pass a dedicated squatter-removal law creating a faster citation process: HB 332 in 2025 and HB 144 in 2026 both died in committee (postponed indefinitely) and were never signed by the governor, so no expedited squatter-specific statute currently exists. Only a sheriff or other law enforcement officer executing a court-issued writ of restitution can lawfully remove an occupant who refuses to leave voluntarily; owners may not change locks or remove belongings on their own.
