House Bill 1319 amends the Business Organizations Code enacted during the 78th Legislature, Regular Session, 2003, to incorporate changes made to the prior source law by bills passed during that legislative session and make those laws consistent with the new code. These bills relate to domestic and foreign business organizations, including general and limited partnerships, limited liability partnerships, and foreign limited liability partnerships, and to nonprofit corporations. House Bill 1319 incorporates simplified procedures for the entities to file certificates of formation and other business documents with the secretary of state and clarifications of certain provisions relating to meetings, voting, mergers, and shareholders. The bill provides that on or after January 1, 2010, the bill's provisions apply to a corporation created under a special statute of this state before January 1, 2006. It allows a filing entity to elect for these provisions to apply to the corporation prior to January 1, 2010, by filing a statement with the secretary of state and taking certain other actions. The bill authorizes a domestic or foreign filing entity whose registration to do business has been revoked or otherwise canceled to reinstate its registration on or after January 1, 2006, and before January 1, 2010.
