Mich. Comp. Laws § 700.3305: Informal probate; register not satisfied.

Sec. 3305.

If the register is not satisfied that a will is entitled to be probated in informal proceedings because of failure to meet the requirements of section 3303 or 3304 or for another reason, the register may deny the application. A register's denial of informal probate is not an adjudication and does not preclude formal probate proceedings. If the application is denied, the register shall clearly state the reason for denial.
