Missouri Articles of Merger for Parent Subsidiary Corporations are documents used to legally merge two separate corporate entities (parent and subsidiary) into a single legal entity. The parent corporation absorbs the subsidiary, and the subsidiary ceases to exist as a separate entity. The Missouri Articles of Merger must be filed with the Missouri Secretary of State in order to be legally recognized. There are two types of Missouri Articles of Merger for Parent Subsidiary Corporations: Short-Form Merger and Long-Form Merger. A Short-Form Merger is used when the parent corporation owns at least 90% of the subsidiary. This type of merger requires fewer documents to be filed with the Missouri Secretary of State, and is the most common type of merger. A Long-Form Merger is used when the parent corporation owns less than 90% of the subsidiary. This type of merger requires more documents to be filed with the Missouri Secretary of State. The documents required are: a Certificate of Merger, a Statement of Merger, and a Certificate of Good Standing for both the parent and subsidiary corporations.
