A Delaware Certificate of Merger of Domestic Limited Liability Companies is a legal document used to merge two or more domestic limited liability companies (LCS) in the state of Delaware. It specifies the details of the merger, such as the date of the merger, the name of the surviving LLC, and the terms of the merger. The Certificate of Merger must be filed with the Delaware Secretary of State in order for the merger to be effective. There are two types of Delaware Certificate of Merger of Domestic Limited Liability Companies: short-form merger and long-form merger. A short-form merger is used when the surviving LLC is the same as the merging LCS, while a long-form merger is used when the surviving LLC is different from the merging LCS.
