Michigan Compiled Laws, Chapter 500. Insurance Code of 1956 § 500.121

Sec. 121. (1) A person and a surety may agree to deposit any asset that the surety may be held responsible for into a financial institution that is authorized to transact business in this state in such manner as to prevent the withdrawal of the asset or any part of the asset except with the written consent of the surety or an order of the court made on such notice to the person and the surety as the court directs.

(2) A person acting in a fiduciary capacity who is required to obtain a bond may include the cost of obtaining the bond as part of the expense of acting as a fiduciary if allowed by the court to which the fiduciary is required to account and so long as the cost does not exceed 1% annually of the bond amount or an amount otherwise approved by the commissioner. The surety on a bond under this subsection may apply to the court for an order relieving the surety of liability for future acts of the fiduciary. Following notice and a hearing, the court may enter an order discharging the surety from liability arising out of acts or omissions occurring after the date of the order on such terms and conditions as the court considers necessary to protect the fiduciary estate and its beneficiaries.

(3) A person required to furnish a bond may use any surety that holds a certificate of authority issued under this chapter and so long as the amount of the bond is within the surety's risk limitation under section 640.  1

(4) Upon payment of the obligation secured by the bond, a surety is subrogated to the rights of the party to whom it made payment including any security or priority to which its subrogor was entitled.

(5) The corporate surety on a bond shall be released or discharged from its liability on the same terms and conditions as are applicable to the release or discharge of individual sureties. A surety has all rights, remedies, and relief to which an individual guarantor or indemnitor would be entitled.
