Hello again and thank you for providing this additional information.
A MI court can grant visitation time to a grandparent where the parents are not married. The grandparent need not prove that the children are in danger in order to obtain such visitation, but must show that visitation would be in the best interests of the children.
Here is a link which summarizes the grounds on which a grandparent may seek visitation rights:
However, where it appears that a child may be in danger while in the parent's custody, a grandparent could actually seek guardianship
of the child, which is what you may be seeking to do. In that case, the grandparent must normally prove that the parents are unfit or unable to provide a nurturing environment in addition to proving that it would be in the child's best interests to grant the grandparent custody of the child.
If CPS were contacted and informed of the potential danger to the child, they would have the obligation to investigate the complaint. If their investigation supported a finding that the child was in danger, that would typically bolster the grandparent's pursuit of guardianship.
