File at the Magistrate Court in the New Mexico county where the roommate is located, does business, or where the dispute occurred.

Present your case at the hearing

Sample Demand Letter: Roommate Dispute
Send this demand letter via certified mail before filing. Courts view prior good-faith attempts favorably, and many disputes settle at this stage. Replace the bracketed placeholders with your details.
I am writing to formally demand $[AMOUNT] from [DEFENDANT NAME] representing [INCIDENT DESCRIPTION], which remains unpaid as of [DATE] despite my prior requests. As [PLAINTIFF NAME] and your co-tenant or former co-tenant, you agreed to share responsibility for rent and/or damage-related costs under our shared living arrangement, and you have failed to fulfill that obligation. This letter constitutes my final demand for payment before legal action. If you do not pay the full amount owed within 14 days of the date of this letter, I will file a claim against you in small claims court to recover the outstanding balance plus court costs.
This is a template only — not legal advice. Consult an attorney if your situation is complex or the amount is significant.
