N.M. Stat. § 53-6-9
Issuance and transfer of shares.
Shares of stock of a professional corporation shall be issued and transferred only to
persons who are duly licensed or legally authorized to render the professional service
for which the corporation is organized, but such shares may be transferred:
A. by operation of law to persons or legal entities not so licensed or authorized,
subject to the requirements of the Professional Corporation Act;
B. to a revocable trust the grantor of which is such a duly licensed or authorized
person, provided that the trust contains provisions that require the trustee, upon the
grantor's death or disqualification to render the professional service for which the
grantor was licensed or authorized, to dispose of the shares as otherwise provided in
the Professional Corporation Act; and
C. to a tax-qualified employee benefit plan established for the exclusive benefit of
the professional corporation's employees, provided that the plan's trustee is required to
dispose of the trust's shares as provided in the Professional Corporation Act before
transfer or distribution of the shares to beneficiaries of or participants in the plan who
are not duly licensed or authorized to render the professional service for which the
corporation is organized.
