Michigan Compiled Laws, Chapter 552. Divorce § 552.6

Sec. 6.  (1) A complaint for divorce may be filed in the circuit court upon the allegation that there has been a breakdown of the marriage relationship to the extent that the objects of matrimony have been destroyed and there remains no reasonable likelihood that the marriage can be preserved.  In the complaint the plaintiff shall make no other explanation of the grounds for divorce than by the use of the statutory language.

(2) The defendant, by answer, may either admit the grounds for divorce alleged or deny them without further explanation.  An admission by the defendant of the grounds for divorce may be considered by the court but is not binding on the court's determination.

(3) The court shall enter a judgment dissolving the bonds of matrimony if evidence is presented in open court that there has been a breakdown in the marriage relationship to the extent that the objects of matrimony have been destroyed and there remains no reasonable likelihood that the marriage can be preserved.
