My questions concerns step grandparents. The facts are the boyfriend killed the mother of his baby. Boyfriend is now in jail. Michigan courts granted joint custody to parents of girlfriend who are not married to each other. Maternal grandmother lives in Michigan.
Maternal grandfather is married and lives in another state.
It seems to me the step grandmother would have no rights except what flows from the maternal grandfather has long as step grandmother stays married to and live under same roof and jurisdiction as the maternal grandfather. I do not see where the step grandmother would have any rights concerning the child. According to the facts given, custody rights were only given to the two parents of deceased mother. I do not believe that the step grandmother would have any legal rights even if she is living with a grandparent with custody.
