Challenging Illegal Rental Fees in New Mexico

Feeling confused by suspicious fees on your rent bill in New Mexico? You're not alone. Many tenants wonder which charges are legal and what to do if something looks wrong. New Mexico law protects renters from some unfair or excessive fees, but it can be tough to know your rights and next steps. This guide explains how to spot illegal fees, challenge them, and where to find official forms and support.

Understanding Rental Fees in New Mexico

According to the New Mexico Uniform Owner-Resident Relations Act, landlords may only impose certain types of fees – and must disclose these clearly in the written lease1. Common legal fees include:

  • Late rent fees (within state limits)
  • Returned check fees
  • Reasonable application fees

Fees must be reasonable, clearly stated in your lease, and comply with state law. Charges that are unexpectedly added, not described in your lease, or excessively high may be illegal. For the most up-to-date information, check the New Mexico Administrative Code (Title 14) for housing regulations.

Examples of Illegal or Questionable Fees

  • "Administrative" or "processing" fees not mentioned in the lease
  • High or recurring maintenance charges for repairs you did not request
  • Unauthorized "move-in" or "move-out" fees
  • Late charges above the legal or "reasonable" amount
  • Charges for services which are the landlord's responsibility (such as ordinary repairs)

If any fee on your rent bill fits these descriptions, you may have the right to challenge it.

How to Challenge an Illegal Fee: Step-by-Step

Tackling an unlawful fee is usually a straightforward process. In most cases, you must first address the issue directly with your landlord in writing. If that doesn't resolve the matter, New Mexico offers official avenues for making a formal complaint.

  • Review your lease agreement for fee clauses.
  • Check the Uniform Owner-Resident Relations Act for legal limits on fees.
  • Gather documentation (rent bills, receipts, and written communications).
  • Write a letter disputing the questionable fee and request removal or clarification. Keep a copy for your records.

Filing a Complaint with the New Mexico Attorney General

If your landlord refuses to correct the issue, you can make an official complaint using the form below.

  • Form Name: "Consumer Complaint Form" (no specific number)
  • When to use: If you believe your landlord is charging illegal or excessive fees, and you have been unable to resolve the matter directly.
  • How to use: Complete the form describing the issue, upload supporting documents, and submit electronically or by mail. The Attorney General’s office will investigate housing complaints involving fee violations.
  • Access the Consumer Complaint Form (Attorney General, NM)

Tip: Always communicate in writing and keep documentation of all fees, letters, and responses. This helps protect your rights if legal action becomes necessary.

Small Claims Court as a Last Resort

If a landlord refuses to refund an illegal fee, you may file a case in New Mexico Magistrate Court (Small Claims Division). The process is designed for individuals and does not require an attorney.

  • Form Name: "Complaint/Summons (Civil) - Landlord/Tenant"
  • When to use: To request the refund of an illegal fee after attempts to resolve have failed.
  • How to use: File the form at your local Magistrate Court with evidence of the fee and your attempts to address it.

FAQ: Challenging Illegal Fees on Rent Bills in New Mexico

  1. Can my landlord charge a late fee if it's not in my lease? No. Under New Mexico law, only fees disclosed in your lease can be enforced. Surprise fees are generally not allowed and may be challenged.
  2. Is there a limit to how much a landlord can charge in late fees? While UORRA does not set an exact maximum, fees must be "reasonable" and clearly stated. Excessive or hidden fees could be challenged.
  3. How do I report an illegal fee? Begin by notifying your landlord. If unresolved, use the Consumer Complaint Form from the Attorney General, or file a complaint with the Magistrate Court.
  4. Do I need a lawyer to challenge an illegal fee? Not usually. Many disputes can be handled directly with your landlord or through Magistrate Court, where legal representation is optional.
  5. What if the landlord retaliates after I complain? Retaliation (like increased rent or threats of eviction in response to a dispute) is prohibited under New Mexico’s UORRA. Document all interactions and contact the Attorney General if you feel your rights are violated.
