Michigan Compiled Laws, Chapter 380. School Code of 1976 § 380.907

Sec. 907. (1) If a school district which has bonded indebtedness proposes to annex a school district which has bonded indebtedness, the resolution of the annexing board prescribed by section 901  1 may provide that the annexation shall become effective only if the school electors of the annexing school district approve the assumption of the bonded indebtedness of the school district to be annexed and the school electors of the school district to be annexed at the same election approve the assumption of the bonded indebtedness of the annexing school district and approve the annexation.

(2) If the annexation is effective, the combined school district shall assume the obligation of the bonded indebtedness of both the annexing and annexed school districts and shall pay the same by levying debt retirement tax levies uniformly over the territory of the district. The assumption of the bonded indebtedness by the annexing school district shall not operate to release the territory of the annexing school district or of the annexed school district from the final responsibility of paying the bonded obligation.
