Is a squatter a tenant — and what rights do they have?
No. New Mexico’s landlord-tenant act only protects someone who signed a rental agreement with you, so none of its protections reach a person who never had one. That does not mean you may put them out yourself — the state still routes you through a court.
›Read the law — 3 provisions
If a trespasser counts as a tenant, the owner is routed into housing court and every fast option closes.
1 · NMSA 1978, § 47-8-3(Q) — "resident" defined, Uniform Owner-Resident Relations Act · secondhand source
“a person entitled under a rental agreement to occupy a dwelling unit in peaceful possession to the exclusion of others and includes the owner of a mobile home renting premises, other than a lot or parcel in a mobile home park, for use as a site for the location of the mobile home”
SECONDARY: read on FindLaw, because the official New Mexico compilation (nmonesource.com) answers every request with a CAPTCHA. A human should confirm it against the official code. The Act defines a "rental agreement" at § 47-8-3(P) as "all agreements between an owner and resident … embodying the terms and conditions concerning the use and occupancy of a dwelling unit or premises."

“The provisions of Sections 35-10-1 through 35-10-6 NMSA 1978 shall not apply to actions by a landlord arising out of a residential tenancy governed by the Uniform Owner-Resident Relations Act.”
SECONDARY: read on FindLaw; the official compilation is behind a CAPTCHA. The compilation prints a bracketed cross-reference — "[47-8-1 to 47-8-52 NMSA 1978]" — after the Act’s name. Bracketed material is inserted by the compiler and is not part of the law, so it is left out of the quotation above.

“A civil action for forcible entry or unlawful detainer of real property is commenced by the filing of a civil complaint alleging that one or more of the following facts exists: (1) the defendant entered and occupied the lands and tenements of another against the will or consent of the owner and refused to vacate the premises after notice by the owner or his agent or attorney;”
SECONDARY: read on FindLaw; the official compilation is behind a CAPTCHA. "Forcible entry or unlawful detainer" is the statute’s name for the possession case — it is what YOU file, not something you are charged with. Read the other four grounds beside it: (2) holding over after a lease ends, (3) failing to pay rent, (4) staying on after a foreclosure sale, (5) a month-to-month or at-will tenant staying after thirty days’ notice. Only the first reaches a person who never had an agreement with you at all.
