Daughter is not letting me see my grandchildren
Yes, but under limited circumstances. A grandparent may seek grandparenting time in many situations including actions for divorce, circumstances where the grandparent’s child is deceased, unmarried parents residing separately and the father has established paternity, custody is given to a third party and the child is placed outside the parental home, or in the year preceding the commencement of an action for grandparenting time, the grandparent provided an established custodial environment for the child. MCL 722.27b(1).
The courts give the benefit of the doubt to the parent, so if they find that a "fit parent" is deciding not to let a grandparent see the child, the court will deny grandparent visits unless you can prove to the court that failure to exercise grandparenting time would create a substantial risk of harm to the child.
