MBCA State Liaisons

State Liaisons to the Corporate Laws Committee keep the Committee abreast of corporate law developments in their respective states (primarily amendments of corporation laws and other legislation and important judicial decisions relating to corporation laws).  The Committee endeavors to keep State Liaisons abreast of amendments of the MBCA and solicits their comments from time to time with respect to proposed amendments and other matters.
