How long does a New Mexico landlord have?
Under N.M. Stat. § 47-8-18, a New Mexico landlord has 30 days after your tenancy ends to return your deposit or provide an itemized statement of any deductions. New Mexico requires that itemized statement when the landlord keeps any part of the deposit. Count from the day the tenancy ended. If the deadline has passed and you haven’t been paid or itemized, your landlord is late — and that’s the leverage your demand letter is built on.
What penalty can a New Mexico landlord face?
A landlord who keeps a deposit improperly may face the statutory consequences below. Specifically, under N.M. Stat. § 47-8-18, New Mexico law lets a tenant seek the right to retain, which the landlord forfeits in bad faith; a $250 civil penalty plus court costs and attorney's fees may apply.

How to get your deposit back in New Mexico
- 1. Send a written demand. Put the deadline your landlord missed and the statute (N.M. Stat. § 47-8-18) in writing, by certified mail with return receipt, so you have proof of the date they received it.
- 2. Keep your records. Move-out photos, the walkthrough checklist, your lease, and proof you gave a forwarding address are your evidence if the landlord disputes the claim.
- 3. If they don’t pay, file in small claims. You can ask a New Mexico small claims court to order the deposit returned, and — under N.M. Stat. § 47-8-18 — to seek the right to retain, which the landlord forfeits in bad faith; a $250 civil penalty plus court costs and attorney's fees may apply plus attorney's fees, which the court may award if you prove your case. The small-claims dollar limit varies by court within the state, so check your county’s limit before filing.
