Unpaid personal loan in New Mexico small claims
Friend or family owes you money? Recover it in small claims.
Lending money to a friend or family member without repayment can lead to a small claims case. You do not need a formal promissory note to sue, but having written evidence of the loan — even text messages or emails confirming the amount and a promise to repay — dramatically strengthens your case. The key elements are proving the loan was made, the amount, and that repayment was due.
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).
Unpaid personal loan: steps that matter
- Gather all evidence of the loan: bank transfers, cash-withdrawal records, texts, emails, or any written note agreeing to repay.
- Calculate the amount owed including any agreed interest, and confirm when repayment was supposed to occur.
- Send a written demand for repayment with a clear deadline and keep proof you sent it.
- Confirm you are within the statute of limitations below before filing — the clock may have started from the repayment due date.
- File in the court where the defendant lives or where the loan was agreed to.
Filing your Civil Complaint (Form 4-201) in New Mexico
- 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.
- 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.
- 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.
- 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.
- 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 unpaid personal loan
A personal loan is a contract or debt claim — you lent money on a promise to repay. If you have a written loan agreement, the written-contract statute of limitations typically applies. If the loan was only a verbal agreement, the oral-contract or debt period usually governs. The limitations clock generally starts from the date repayment was due or the last payment 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.
Appeals: Either party may appeal to the district court within 15 days of the judgment being filed. The appeal is a trial de novo; the district court filing fee is $132.
