How to Sue for Your Security Deposit in New Mexico Small Claims Court

The 30-Day Rule Your Landlord Has to Follow

Under NMSA 1978 § 47-8-18 (the Uniform Owner-Resident Relations Act), if your landlord keeps any part of the deposit, they must provide an itemized written statement of deductions and return any remaining balance within 30 days after the later of the rental agreement's termination or your departure. The landlord is deemed to comply by mailing the statement and any payment due to your last known address.

If the deadline passes without the required accounting and any balance due being timely provided or mailed to your last known address, the landlord forfeits the right to withhold any part of the deposit. The separate $250 civil penalty applies only when the landlord retained the deposit in bad faith.

What You Can Claim

Your small claims complaint can include:

The deposit itself. If the landlord did not timely provide or mail the required itemized statement and any balance due to your last known address, § 47-8-18 says the landlord forfeits the right to withhold any portion of the deposit.

The $250 bad-faith penalty. NMSA 1978 § 47-8-18 allows a $250 statutory penalty when the landlord retains a deposit in bad faith in violation of the statute. A missed accounting deadline alone does not establish bad faith.

Reasonable attorney's fees and court costs. Section 47-8-18 provides for court costs and reasonable attorney's fees when the landlord fails to provide the required accounting by the deadline.

The deposit and any statutory penalty count toward the $10,000 principal-damages limit; interest and allowable court costs are calculated separately. For most security deposit disputes — where deposits range from $500 to $3,500 — you'll be well within that ceiling.

Before You File: A Written Demand Can Help

A written demand can help document the dispute, but § 47-8-18 does not make it a pre-filing requirement for recovering the deposit. The $250 civil penalty requires bad-faith retention.

Your demand letter should:

• State the date you moved out and the deposit amount
• Note that 30 days have passed since the later of the rental agreement's termination or your departure without timely accounting or return of any balance due being mailed to your last known address
• Demand return of the deposit within a specific timeframe (10–14 days is standard)
• Mention that you'll file in small claims court if the demand isn't met
• Reference NMSA 1978 § 47-8-18

Send it by certified mail with return receipt requested. Keep the green card — it's evidence of delivery if the case goes to court.

Choosing Your Court

• Bernalillo County (Albuquerque) → File Form 4-202 at the Metropolitan Court
• Any other county → File Form 4-201 at the local Magistrate Court in the county where the rental property is located or where the landlord resides

The filing fee is $72–$87, depending on the court. If the landlord is a property management company, check the Secretary of State's Business Search for the registered entity name and registered agent — you need the correct legal name for an enforceable judgment.

Building Your Evidence

Security deposit cases are won on documentation. Gather:

• Your lease showing the deposit amount and move-in date
• Move-in and move-out photos — timestamped photos of the unit's condition when you took possession and when you left
• Your move-out notice proving you gave proper notice
• Proof of the demand letter — your certified mail receipt and the green return receipt card
• Communication records — texts, emails, or letters between you and the landlord about the deposit
• The landlord's itemized statement (if they sent one) — you may be disputing specific deductions rather than a total failure to account

If the landlord claims deductions for "damage," compare the unit's condition to normal wear and tear. Faded carpet, minor nail holes, and paint scuffs from everyday living aren't tenant damage under New Mexico law.

What to Expect at the Hearing

These cases usually come down to two questions: Did the landlord comply with the 30-day accounting requirement? And if they made deductions, were those deductions reasonable?

Present your timeline clearly: move-out date, 30-day deadline, when (or whether) you received any accounting, your demand letter, and the landlord's response. Let the documents tell the story.

If the landlord provides an accounting after the statutory deadline, that does not restore the right to withhold any part of the deposit. The separate $250 penalty still requires bad faith.
