Roommate money dispute in New Mexico small claims

Ex-roommate owes you money? Recover it in small claims.

When a roommate leaves without paying their share of rent, utilities, or other agreed expenses — or when money was lent and not repaid — small claims court is an accessible option to recover. Your case turns on showing what was agreed, what was paid by each person, and what remains unpaid. A written roommate agreement or lease addendum is the strongest evidence, but texts, emails, and payment records can also establish the arrangement.

In New Mexico, small-claims cases are heard in the Magistrate Court (Metropolitan Court in Bernalillo County) and you can sue for up to $10,000.

Good to know: New Mexico has no court named small claims court. Civil money claims up to $10,000 go to the Magistrate Court (in 32 of 33 counties) or, in Bernalillo County, the Metropolitan Court. Both use the same statewide civil forms (Civil Complaint 4-201 for magistrate, 4-202 for Metro).

Roommate money dispute: steps that matter

  1. Gather your roommate agreement, lease, and any written communications about shared expenses, payments made, and what was owed.
  2. Compile payment records showing what you paid and what the other person did or did not pay.
  3. Send a written demand for the amount owed and keep proof you sent it.
  4. File in the court for the county where the rental property is located or where the defendant currently lives.

Filing your Civil Complaint (Form 4-201) in New Mexico

  1. Complete the Civil Complaint. Fill out the Civil Complaint (Form 4-201 magistrate, 4-202 Metro) stating proper venue, the amount claimed (up to $10,000), and a brief description of the event. Forms are free at nmcourts.gov.
  2. File with the clerk and pay the fee. File with the magistrate or metropolitan court clerk for the county where the defendant is or the claim arose, and pay the $72 docket fee (NMSA 35-6-1; Metro adds a $5 mediation fee). A fee waiver is available for indigency.
  3. Have the summons issued and served. Get a Civil Summons (Form 4-204) from the clerk. The summons, complaint, and answer form are served on the defendant by a sheriff or any uninvolved adult over 18. File the return of service.
  4. Wait for the defendant's response. The defendant has 20 days after service to file an answer. If none is filed, you may ask for a default judgment.
  5. Attend the trial. If the defendant answers, the court sets a trial. Bring your evidence, documents, and witnesses.

Filing fees: The civil docket fee is set by statute at $72 (NMSA 1978, 35-6-1), the same in magistrate and metropolitan courts and not county-set. The Metro Court adds a $5 small-claims mediation fee. A fee waiver is available on a showing of indigency.

Deadline that applies to your roommate money dispute

A roommate money dispute is usually a contract or debt claim — unpaid shared expenses, a loan between roommates, or one roommate leaving the other holding the lease. The statute of limitations is typically the contract or debt period, starting from when the money was due or the last payment was made.

Written contract: 6 years (NMSA 1978, Section 37-1-3)

Answering a lawsuit: 20 days after the summons is served.

Serving the defendant: The Civil Summons, complaint, and answer form are served by a sheriff or any non-party adult over 18, by personal delivery, by leaving them with someone over 15 at the defendant's home, or by posting plus mailing. A signed return of service is then filed.
