Michigan Compiled Laws, Chapter 492. Installment Sales of Motor Vehicles § 492.110

Sec. 10. (a) The administrator is authorized and empowered to investigate and examine at any time during regular business hours any and all books, accounts, papers, records, documents and files, to the extent that such investigation and examination pertain to matters regulated under the provisions of this act, of any licensee and of any person who shall be engaged in business contemplated by this act. For this purpose the administrator shall have free access to the offices and places of business and any and all books, accounts, papers, records, documents and files of all such persons. A person who is not licensed under this act shall be presumed to be engaged in business contemplated by this act, if he, as principal, agent or broker advertises or solicits business for which a license is required by the provisions of this act, and the administrator and any person designated by him for that purpose is, in such case, hereby empowered to examine the books, accounts, papers, records, documents, files, safes and vaults of such persons for the purpose of discovering violations of this act.

(b) The administrator is empowered to require the attendance and testimony of witnesses and the production of any books, accounts, papers, records, documents and files relating to such business which the administrator has authority by this act to investigate, and for this purpose the administrator or his duly authorized representative may sign subpoenas, administer oaths and affirmations, examine witnesses and receive evidence. In case of disobedience of any subpoena or the contumacy of any witness appearing before the administrator, the administrator may invoke the aid of the circuit court of Ingham county, or any circuit court of the state, and such court shall thereupon issue an order requiring the person subpoenaed to obey the subpoena, or to give evidence, or to produce books, accounts, papers, records, documents and files relative to the matter in question. Any failure to obey such order of the court may be punished by such court as a contempt thereof.

(c) The administrator is hereby authorized and empowered to prescribe the various blank forms to be used by licensees in making reports, and to make rules and regulations relating to the enforcement of this act. A copy of every rule and regulation shall be mailed by the administrator to all licensees under this act at their respective licensed places of business at least 10 days before the effective date thereof.
