New Mexico Criminal Defense Laws
New Mexico classifies felonies into four degrees (capital, first through fourth) plus misdemeanors and petty misdemeanors. The death penalty was abolished in 2009 — the maximum sentence is life imprisonment. New Mexico enacted a comprehensive Criminal Record Expungement Act in 2019, allowing expungement of most convictions after waiting periods that range from 2 to 10 years depending on severity. DWI convictions cannot be expunged. New Mexico uses "DWI" (not DUI) with a BAC threshold of 0.08% and aggravated DWI at 0.16%.

Capital felonies, first-degree violent felonies, and second-degree murder have no statute of limitations. Second-degree felonies must be charged within 6 years. Third and fourth-degree felonies must be charged within 5 years. Misdemeanors within 2 years. Petty misdemeanors within 1 year.
Exceptions
