N.M. Stat. § 61-28B-25
Working papers; client records.
A. A statement, record, schedule, working paper or memorandum made by a
certificate or permit holder incident to rendering a service to a client shall be the
property of the certificate or permit holder in the absence of an express agreement
between him and the client to the contrary, except the report submitted by him to the
client and except for a record that is part of the client's records. No such item shall be
sold, transferred or bequeathed without the consent of the client or the client's personal
representative, except to a partner, stockholder or member of the firm or any combined
or merged firm or successor in interest to the certificate or permit holder. Nothing in this
section shall prohibit any temporary transfer of a work paper or other material necessary
in the course of carrying out a peer review or as otherwise interfering with the disclosure
of information pursuant to the 1999 Public Accountancy Act.
B. A certificate or permit holder shall furnish to a client or former client, upon
request and reasonable notice:
(1)
a copy of his working paper, to the extent that such working paper
includes a record that would ordinarily constitute part of the client's record and is not
otherwise available to the client; and
(2)
an accounting or other record belonging to, or obtained from or on behalf
of, the client that he removed from the client's premises or received for the client's
account; he may make and retain a copy of a document of the client when they form the
basis for work done by him.
