Michigan Compiled Laws, Chapter 388. Schools and School Aid § 388.718

Sec. 8. If a district attached under the provisions of this act at the time of reorganization, has a bonded indebtedness incurred after December 8, 1932, its identity shall not be lost and its territory shall remain as an assessing unit for purposes of such bonded indebtedness until the indebtedness has been retired or the outstanding bonds refunded by the reorganized district. The board of the reorganized district, or the board of the district which has succeeded to the largest share of the state equalized valuation of the attached district, shall constitute the board of trustees for the original district having bonded indebtedness and the officers of the reorganized or successor district shall be the officers for the original district. The board of the reorganized or successor district shall certify and order the levy of taxes for the bonded indebtedness in the name of the original district, shall not commingle the debt retirement funds of the original district with funds of the reorganized or successor district and shall do all things relative to such bonded indebtedness required by law and by the terms under which the issue and sale of the bonds were originally authorized. All other tax levies for purposes of the reorganized district shall be spread over the entire area of the reorganized district.
