A Delaware Certificate of Ownership and Merger — Parent Into Subsidiary is a legal document used in the state of Delaware to effect a merger where a parent corporation merges into a subsidiary. It is filed with the Delaware Secretary of State, and the merger is effective upon filing. The document contains the name and mailing address of the parent corporation, the name of the subsidiary, the date of the merger, and the name of the surviving corporation. It also contains a statement of the purpose of the merger, and a statement that the merger has been approved by the Board of Directors of the parent corporation. There are two types of Delaware Certificate of Ownership and Merger — Parent Into Subsidiary: Short Form, and Long Form. The Short Form is the most commonly used and is used to effect a merger between two corporations that are already organized under the laws of Delaware. The Long Form is used to effect a merger between a parent and subsidiary that are not incorporated in Delaware. In this case, the Long Form contains additional information such as the incorporation date and jurisdiction of incorporation of the parent and subsidiary, and the address of the registered office for the surviving corporation.
