A corporation’s bylaws or internal shareholder agreements may restrict a stockholder’s right to transfer shares. Those restrictions may include:
– to seek a prior approval from the remaining stockholders to make a transfer of shares to a third parties;
– to offer sale of stock first to the remaining shareholder (i.e., the right of first refusal); or
– any other limitations.
Failure to receive such an approval makes a transfer of stocks under the present agreement void (i.e., not legally binding).
