Legal Question in Family Law in Michigan

I'm not entirely sure what you're asking, whether you're asking to terminate her rights or whether you want to know how to get sole custody. Nor do you tell me whether there is a current order in place. In any case, all parents are presumed to be fit. To show that a parent is unfit, you need a lot of concrete evidence like drug abuse, mental illnesss, abuse, or other very unusual activities to show a parent is unfit.
