New Mexico small claims cases are heard in Magistrate Court across 32 counties, or in the Bernalillo County Metropolitan Court for Albuquerque-area cases, both capped at $10,000 under N.M. Stat. §§ 35-3-3 and 34-8A-3. New Mexico gives written contract plaintiffs a generous 6-year filing window under § 37-1-3, and its Magistrate Court judgments remain enforceable for a notably long 14 years — above average compared to many other states covered in this guide series.
New Mexico’s most distinctive feature involves a genuine split in appeal rights depending on which court hears your case. A Magistrate Court judgment can be appealed by either party within 15 days for a full trial de novo. But Metropolitan Court practice in Bernalillo County works differently: a plaintiff who chooses to file there waives the right to appeal an unfavorable outcome by selecting that forum — echoing, in a more geographically limited way, the plaintiff-appeal-waiver structures found in Massachusetts and Rhode Island, both covered elsewhere in this guide series. New Mexico also applies a genuinely distinctive post-judgment interest bifurcation: most judgments accrue interest at 8.75%, but tort judgments against an insured defendant specifically accrue at a higher 15% — a split based on the defendant’s insurance status rather than the more common contract-versus-tort distinction used elsewhere. This guide covers the complete New Mexico small claims process — filing in the correct court for your county, the security deposit bad-faith penalty, the appeal-rights split between Magistrate and Metropolitan Court, and the specific collection tools available once you have a judgment.

What Makes New Mexico Small Claims Different
1. Metropolitan Court Plaintiffs Waive Their Appeal Rights by Choosing That Forum
If your case falls in Bernalillo County and you file in the Metropolitan Court, you take on a genuine trade-off many filers don’t anticipate: the plaintiff who chooses this forum waives the right to appeal an unfavorable outcome. This differs from Magistrate Court practice in New Mexico’s other 32 counties, where either party retains a 15-day appeal right for a full trial de novo. This forum-specific plaintiff waiver echoes, on a smaller geographic scale, similar plaintiff-restricted appeal structures found in Massachusetts and Rhode Island, both covered elsewhere in this guide series. If you are filing in the Albuquerque area and there is any realistic chance you’ll want to appeal an adverse decision, understand this trade-off before choosing Metropolitan Court over an available alternative.
2. Post-Judgment Interest Depends on Whether the Defendant Is Insured
Most New Mexico judgments accrue interest at a standard 8.75% per year. But tort judgments specifically against an insured defendant carry a meaningfully higher 15% rate. This is a genuinely distinctive bifurcation — rather than splitting the rate by contract versus tort claim type, the way West Virginia does, covered elsewhere in this guide series, New Mexico instead conditions the higher rate on the defendant’s insurance status specifically within tort claims. If your case involves a tort claim against a defendant you know or suspect carries liability insurance, confirm which rate actually applies to your judgment.
3. Security Deposit Violations Carry a Built-In Double-Damages Penalty
Under N.M. Stat. § 47-8-18, a landlord who misses the 30-day security deposit return deadline without a valid reason faces a built-in statutory penalty of double the wrongfully withheld amount — not merely the original deposit itself. This gives New Mexico tenants a genuinely meaningful incentive structure: a landlord who simply ignores the return deadline risks owing twice what they withheld, not just the original sum.
4. Two Different Courts Depending on Where You Live
New Mexico’s small claims structure isn’t handled by a single statewide court type. Bernalillo County — the Albuquerque metropolitan area — uses the Metropolitan Court specifically. All of New Mexico’s other 32 counties use Magistrate Court instead. Both share the same $10,000 jurisdictional cap, but as described above, their appeal rules differ meaningfully. Confirm which court actually has jurisdiction over your specific case based on the defendant’s location before assuming a single, uniform process applies everywhere in the state.
5. A Notably Long 14-Year Judgment Validity Period
A New Mexico small claims judgment remains valid and enforceable for 14 years — above average compared to the 5- to 10-year periods common in many other states covered in this guide series, though shorter than the 20-year periods found in Massachusetts and New Hampshire. If your defendant currently has no attachable wages or assets, this extended window gives your judgment real, lasting value even if their financial circumstances only improve years down the road.
New Mexico Small Claims Filing Fees (2026)
| Item | Cost |
|---|---|
| Filing fee (tiered by claim amount) | $30 – $132 |
| Service of process (sheriff, process server, or certified mail) | Additional cost — confirm with clerk |
If you win, the court can typically add your filing fee and service costs to the judgment, so the defendant ultimately owes your original claim plus these costs.
Fee waiver: Fee waivers are available for qualifying low-income filers — ask the clerk for the appropriate application.
Step-by-Step: How to File in New Mexico
Step 1 — Confirm Any Required Administrative Process
For certain claim types — most commonly employment discrimination — you may need to file with and complete a process before an administrative agency before suing in New Mexico state court, including small claims. This runs concurrently with, not instead of, your statute of limitations, so track both deadlines. Once the limitations period expires, you lose your right to sue regardless of the administrative process’s status.
Step 2 — Send a Demand Letter
New Mexico does not require a demand letter before filing, but sending one by certified mail with return receipt requested strengthens your case. Keep proof of delivery for your hearing.
Step 3 — Confirm the Correct Court for Your County
If your case is in Bernalillo County, file in Metropolitan Court. For all other counties, file in Magistrate Court covering the defendant’s residence or where the incident occurred. Filing in the wrong venue allows the defendant to ask the court to move or dismiss your case.
Step 4 — Complete the Small Claims Complaint
Obtain plain-language forms specifically designed for magistrate court use from the New Mexico Courts website (nmcourts.gov). Include:
- Your name and address
- The defendant’s exact legal name and address
- The amount claimed (up to $10,000)
- A brief statement of your claim
Step 5 — File and Pay the Fee
File through New Mexico’s Odyssey e-filing system or in person at the clerk’s window, and pay the applicable fee ($30–$132).
Step 6 — Serve the Defendant
You do not need to serve the defendant yourself — the court typically handles service once you file, though you need a correct address. Service must comply with NMRA Rule 2-202, by process server, sheriff, or certified mail where permitted. The defendant has 20 days to file a written answer; failure to do so results in a default judgment.
Step 7 — Prepare Your Evidence
Bring three copies of every document and all witnesses. Hearings are informal compared to district court trials, and New Mexico’s Rules of Evidence apply in a relaxed form adapted to the magistrate context.
Step 8 — Attend the Hearing
The hearing typically occurs 30 to 60 days after filing. Present your evidence supporting your claim; the defendant can present a defense and any counterclaim. The court enters judgment, enforceable through writs of execution, garnishment, and liens up to the jurisdictional cap.
How to Collect Your New Mexico Small Claims Judgment
Winning a judgment does not automatically put money in your account — you must actively pursue collection if the defendant does not pay voluntarily.
Step 1 — Wage Garnishment
Governed by N.M. Stat. § 35-12-1 et seq. New Mexico protects 75% of disposable wages under § 35-12-7 — meaning only 25% is typically available for garnishment, matching the standard federal baseline.
Step 2 — Bank Account Levy
A writ of execution on financial accounts authorizes seizure of non-exempt funds to satisfy the judgment.
Step 3 — Real Property Lien
Recording your judgment creates a lien against real property the defendant owns — but remember New Mexico’s homestead exemption protects up to $150,000 in equity under § 42-10-9, which may limit what’s actually available for collection against a primary residence.
Step 4 — Post-Judgment Debtor Examination
If you do not know where the defendant works, banks, or holds property, you can compel them to appear and disclose their assets under oath.
Post-Judgment Interest
Interest accrues at 8.75% per year for most judgments, or 15% for tort judgments specifically against an insured defendant.
Out-of-State Defendants
If the defendant is not a New Mexico resident but the cause of action arose in New Mexico — a contract performed here, property damage occurring here, goods delivered here — New Mexico courts may still have jurisdiction under the state’s long-arm statute. Confirm venue rules with the clerk before filing against an out-of-state defendant.
