New Mexico small claims at a glance
New Mexico operates two parallel small claims systems: magistrate courts handle small claims in 32 of 33 counties under N.M. Stat. § 35-3-3, while the Bernalillo County Metropolitan Court (Albuquerque) has its own civil jurisdiction up to $10,000 under § 34-8A-3. The $10,000 limit applies in both courts. Attorneys are permitted under N.M. Stat. § 35-3-7. The 15% post-judgment interest rate on tort judgments against insured defendants (N.M. Stat. § 56-8-4(B)) is one of the highest punitive interest rates in the country and is designed to incentivize prompt insurance payment. Appeals from magistrate court go to district court for trial de novo within 15 days, restarting fact-finding from scratch.
Filing cost example: $6,000 auto-body collision claim
Suppose an Albuquerque driver is owed $6,000 for collision damage by an insured at-fault driver. The property-damage SOL is 4 years under N.M. Stat. § 37-1-4. Filing at the Bernalillo County Metropolitan Court costs about $87 under § 35-6-1. Sheriff service adds approximately $30. Total startup is around $117. The hearing is typically 30-60 days after filing. If the driver wins, post-judgment interest accrues at 15% under N.M. Stat. § 56-8-4(B) because the defendant is insured. After one year of nonpayment, the unpaid amount grows to $6,900 before adding filing and service costs.
