if you are a member of a limited liability company and wish to leave the membership voluntarily, you cannot simply walk away. most allow the members to draft an operating agreement for their llc and it should include procedures for voluntary withdrawal as well as other forms of separation. in certain instances, it is possible the llc will be required to dissolve and re-form if a member leaves, but the typical default is for the llc to maintain its status. if the operating agreement states it as a possibility, you may be able to sell your member shares. every operating agreement should take into account the potential for a member to die or become incapacitated.
