N.M. Stat. § 53-19-33
Right of assignee to become a member.
A. Except as otherwise provided in the articles of organization or an operating
agreement, an assignee may become a member only if the other members unanimously
consent. Such consent shall be evidenced in the manner specified in the articles of
organization or an operating agreement; however, in the absence of such specification,
such consent shall be evidenced by an instrument, dated and signed by the other
members.
B. An assignee who becomes a member has the rights and powers, and is subject
to the restrictions and liabilities of a member under the articles of organization, any
operating agreement and the Limited Liability Company Act. An assignee who becomes
a member shall not be liable for the obligations of his assignor under that act to make
contributions and to return distributions, except to the extent that the assignor and
assignee agree that the assignee is so liable. The assignee shall not, however, be
obligated as a result of his agreement with his assignor for liabilities of which the
assignee had no knowledge at the time the assignee became a member and which
could not be ascertained from the articles of organization or an operating agreement.
C. Whether or not an assignee becomes a member, the assignor is not released
from his liability pursuant to Section 21 [53-19-21 NMSA 1978] of the Limited Liability
Company Act to make contributions to the limited liability company unless all members
consent in writing to such a release.
D. A member who assigns his entire interest in the limited liability company ceases
to be a member or to have the power to exercise any rights of a member when any
assignee of his interest becomes a member as provided in Subsection A of this section.
