N.M. Stat. § 29-3A-8
Expungement of arrest and conviction records; procedure.
A. If a person was charged with an offense involving cannabis that is no longer a
crime on June 29, 2021 or that would have resulted in a lesser offense if the Cannabis
Regulation Act [Chapter 26, Article 2C NMSA 1978] had been in effect at the time of the
offense, whether or not the person is convicted, all public records held by a court or an
agency of the state or a local jurisdiction that relate to the person's arrest or conviction
shall be automatically expunged two years after the date of the person's conviction or
the date of the person's arrest if there was no conviction. If the person is or was under
eighteen years of age at the time of the arrest or conviction, the public records under
this section shall be retained for two years or until the person is eighteen years of age,
whichever comes first, and shall then be automatically expunged. Automatic
expungement under this section applies to public records involving only cannabis and
cannabis paraphernalia charges and requires destruction of the records.
B. The administrative office of the courts shall implement a procedure allowing
persons charged with offenses eligible for automatic expungement under this section to
verify whether automatic expungement has occurred and request expedited automatic
expungement if eligible charges have not yet been expunged.
C. If an arrest or conviction involved cannabis and non-cannabis charges, a person
may request expungement of eligible cannabis charges as defined in Subsection A of
this section by the administrative office of the courts through the procedure
implemented in Subsection B of this section.
D. Requests for expungement to the administrative office of the courts from persons
charged with offenses eligible for automatic expungement shall remain confidential and
are not subject to disclosure.
