Before you file

1–3 weeks before filing

The court rules don't require a demand letter before you file, but asking for payment in writing first is a good idea.

Use the free demand letter generator, give them 10–14 days, and keep a copy with proof of the date you sent it.

In New Mexico you can sue for up to $10,000 in the Magistrate Court (Bernalillo County Metropolitan Court in Albuquerque).

Run the 60-second case check to see the last day you can file.

  • Your full name, address and phone
  • The defendant's exact legal name and a street address where they can be served
  • For a business: its registered agent's name and address
  • The amount you're asking for and how you got that number
  • The date and place the problem happened
  • A short plain description of what happened

Use the company's exact legal name and serve its registered agent or an officer, then also mail a copy.

  • The contract, lease, invoice or receipt
  • Photos of the damage, dated if possible
  • Texts, emails and letters with the other side
  • Two written repair estimates or proof of what you paid
  • Your demand letter and proof it was sent
  • Names and contact details of any witnesses

Fill in the claim

1–2 evenings

  • Who: you and the defendant, with full legal names and addresses
  • What: the agreement or event, in 2–4 plain sentences
  • When: the date it happened
  • How much: the exact amount (no more than $10,000) and how you calculated it

Bring the original and one copy for each defendant, plus one for yourself.

File and pay

Filing day

Choose how you'll file:

OnlineNot availableOnly lawyers can e-file civil cases in Magistrate and Metropolitan Court. Self-represented people file on paper, in person or by mail.
In personTake the Civil Complaint to the Magistrate Court clerk (or Metropolitan Court customer service in Albuquerque) and pay the $77 fee. Cash, money order, cashier's check or card are accepted; personal checks are not.
By mailMagistrate Courts accept new cases by mail with the filing fee. Email or fax filing is only for later papers in a case that has no fee.

File in the county where you live, where the defendant lives, or where the problem happened. In Albuquerque and the rest of Bernalillo County, file at the Metropolitan Court.

$77 to file a civil complaint in Magistrate Court or Metropolitan Court. A jury costs an extra $25 plus a $75 deposit. Service by the sheriff or a process server costs extra. Can't afford it? Ask for a fee waiver: Free Process (fee waiver) application, available from the court clerk.

The clerk issues a Summons. You then arrange service on the defendant with the Summons, Complaint and a blank Answer form.

Serve the defendant

Right after filing

You cannot hand the papers over yourself. Use the sheriff, a private process server, or any adult who isn't part of the case. You can also mail the papers with an Acknowledgment of Service form; if it isn't signed and returned within about 23 days, you must use personal service.

After being served, the defendant has 20 days to file a written Answer.

Return of Service (on the back of the Summons)

Whoever serves the papers fills out the Return of Service, and it must be filed with the court. Without it, your case can be delayed or dismissed.

Don't wait until the hearing. Ask the clerk right away for a new hearing date and try another method, such as personal delivery instead of mail, or a different address.

Before the hearing

1–4 weeks before

The defendant must file a written Answer within 20 days of being served and can include a counterclaim.

If you settle, file a dismissal or a stipulated judgment with the court.

Get any settlement in writing, signed by both sides, with the amount and payment date.

A witness who saw what happened is stronger than a written statement; some judges won't accept letters.

Ask the clerk to issue a subpoena for a witness who won't come voluntarily, and have it served.

  • Three copies of every document: for you, the judge and the defendant
  • A one-page timeline of what happened, with dates
  • A short sheet showing how you calculated the amount
  • Photos printed or ready on your phone (ask the clerk if screens are allowed)

The hearing

Hearing day

  • File your witness and exhibit list at least 20 days before trial
  • Arrive early and check in with the clerk
  • Bring copies of every document for the judge and the other side
  • Bring your witnesses; written statements are rarely enough
  • Turn your phone off and dress neatly

What to say, in about two minutes
  1. Who you are and what you're asking for: the amount.
  2. What the agreement or situation was.
  3. What went wrong, with dates.
  4. What it cost you and how you calculated it, showing your documents.
  5. That you asked for payment and what they said.

Speak to the judge, not the other side. Stay calm, answer the question asked, and don't interrupt.

If the defendant doesn't answer in 20 days, you can ask for a default judgment. If you miss the trial, your case can be dismissed.

After the judgment

Weeks to months

Either side can appeal within 15 days after the judgment is filed. The appeal goes to the District Court in the same county, and the case is tried again from scratch.

The court doesn't collect for you. If they don't pay, you can ask for a writ of execution to seize property or a writ of garnishment for wages or a bank account.

Keep proof of every payment. When you're paid in full, tell the court; some courts require a satisfaction-of-judgment form.
