What the court can and can't do

Small claims is the court's track for everyday money disputes: simplified rules, and limits on how much you can sue for.

Maximum claim

$10,000Maximum claimThe most you can sue for in Los Alamos County small claims
01

Where you can file

Two venues are usually open: where events took place, or where the other side is based.

02

No claim splitting

You can't divide one dispute into several smaller cases to get around the limit.

03

Money judgments only

The remedy here is money. Orders telling someone to do or stop something sit with higher courts.

04

Attorneys allowed, not needed

An attorney may appear at the hearing in New Mexico, though nobody has to have one. The process assumes you will speak for yourself.

05

Age 18 is the threshold

Where a party is under 18, the court appoints a guardian to act.

Over the limit? A claim above the ceiling can be trimmed to fit, or filed in full in the ordinary civil court. Trimming generally means writing off the remainder.

Los Alamos County is under the same limits as nearby Santa Fe County and Sandoval County. Los Alamos County Magistrate Courthouse is the courthouse listed for Los Alamos County.

The cut-off

Every court fixes a minimum number of days between service and the hearing. The clerk will tell you what it is for your case.

The proof that goes on file

Whoever serves the papers completes a proof of service, which is filed with the court before the hearing.
