Michigan Compiled Laws, Chapter 207. Taxation § 207.633

Sec. 13. (1) Any pledge of the distributions of the tax imposed under this act shall be effective, valid, and binding from the time when the pledge is made. The pledged distributions received shall be immediately subject to the lien of the pledge, whether or not there has been physical delivery. The lien of any pledge shall be valid and binding against all parties having claims of any kind in tort, contract, or otherwise against any person receiving the distributions of the tax, whether or not the parties have notice of the pledge. The ordinance, the resolution, or any other instrument of the local governmental unit by which a pledge of the proceeds of the tax imposed pursuant to this act is created is not required to be filed or recorded except in the records of the local governmental unit to be subject to this section.

(2) This section does not constitute a continuing appropriation and shall not be construed to create an indebtedness of the state.
