Michigan Compiled Laws, Chapter 48. County Treasurers § 48.36

Sec. 36. Whichever bond is required under section 35 of this chapter  1 shall be conditioned that the person shall faithfully and properly execute the person's duty and trust, and that the treasurer shall pay according to law all money which shall come to the treasurer's hands as treasurer, and will render a just and true account of that money at any time required by the county board of commissioners, or by law, and that the treasurer shall deliver over to the treasurer's successor in office, or to any other person authorized by law to receive the same, all money, books, papers, and other things appertaining or belonging to the office. If an individual bond for the county treasurer is required, it shall be in an amount as determined by the county board of commissioners and shall be given to the county board of commissioners with 3 or more sufficient sureties as determined by the county board of commissioners. Further, if an individual bond for the county treasurer is required and if the county board of commissioners neglects or refuses, for the period of 20 days after the commencement of the term for which the treasurer was elected, to approve of the sufficiency of the sureties to the bond, or direct the sum in which the same shall be given, the circuit judge, on application of the treasurer elect, may approve of the sufficiency of the sureties of the bond, on being satisfied of their pecuniary responsibility to meet the exigency of the bond, and may direct the sum for which the bond shall be given, not however in a less sum than that directed for the treasurer's predecessor.
