Where to File Small Claims in New Mexico: Venue and Court Selection

New Mexico's Two Small Claims Courts

New Mexico doesn't have a standalone "small claims court." Instead, civil claims up to $10,000 are handled by two separate limited-jurisdiction courts, and where you file depends entirely on geography.

Bernalillo County Metropolitan Court handles qualifying civil claims in Bernalillo County. Its filing guide says the action must have happened in Bernalillo County, the defendant must be served in New Mexico, and either the plaintiff or defendant must live in Bernalillo County. You file using Form 4-202, and proceedings follow NMRA Rules Set 3. The court is a court of record for civil cases other than UORRA landlord-tenant actions.

Magistrate Courts cover the remaining 32 counties, with 46 court locations statewide. You file with Form 4-201, and proceedings follow NMRA Rules Set 2. Magistrate Courts are not courts of record for appellate review. A Magistrate Court appeal goes to District Court as a brand-new trial (trial de novo) within 15 calendar days after the judgment or final order is filed. For other civil Metropolitan Court cases, file a notice of appeal with Metropolitan Court within 30 days from entry of the final order or judgment for on-record review by the Court of Appeals; UORRA landlord-tenant cases have a 15-day de novo appeal to District Court from entry of the judgment or final order.

Magistrate Court Venue Rules Under NMSA § 35-3-6

Even after you identify the right court system, you need to file in the correct location within that system. For Magistrate Court cases, New Mexico venue rules give you up to three options:

1. Where the defendant lives — file in the county or magistrate district of the defendant's residence
2. Where the cause of action arose — file in the county where the dispute happened (where the work was done, where the property is, where the contract was signed or broken)
3. Where the property is located — for claims involving real or personal property, file where that property sits

If the defendant lives in a different county from where the dispute happened, Magistrate Court venue may be proper in either location. But serving papers across county lines requires following specific statutory service rules — the sheriff in one county won't automatically serve someone in another.

Metropolitan Court has separate requirements: the action must have happened in Bernalillo County, the defendant must be served in New Mexico, and either the plaintiff or defendant must live in Bernalillo County.

How to Choose When You Have Options

When venue is proper in more than one location, consider how far you and the defendant would need to travel for a hearing.

That said, if the defendant lives far from you and the dispute happened in your county, filing locally saves you travel for hearings. New Mexico courts do allow remote appearances by teleconference or video under Rules 2-111 and 3-111, but you need to file a motion in advance — it's not automatic.

Filing in the Wrong Court

If you file in a court that lacks venue, the defendant can challenge it, and the court may dismiss or transfer the case. A mistaken filing can cost time and may require you to refile and pay another filing fee — and if the statute of limitations is tight (4 years for oral contracts, 6 for written), that delay could matter.

Filing in the wrong court system is a bigger problem. A Magistrate Court complaint filed for a Bernalillo County dispute, or vice versa, won't be processed. You'd need to refile with the correct court and correct form.

What About Multi-County Defendants?

For businesses, check the New Mexico Secretary of State's online business search for the legal name and registered agent's address; the agent's address is used for service. For venue, apply the Magistrate Court grounds above rather than assuming the agent's county controls. A sole proprietor is sued under the owner's individual name, with the trade name added as d/b/a if applicable.

If you're suing multiple defendants in different counties, confirm venue for the claim and each defendant before filing; do not assume that one defendant's county automatically supplies venue for every defendant.

Making the Right Filing Decision

The New Mexico small claims filing guide includes a court-and-form routing worksheet that walks through the venue decision step by step — which court system, which physical location, and which complaint form to use. Getting this right at the start prevents delays that can stretch a straightforward $77 filing into months of procedural detours.
