Jennifer,
I want to restate your issue to be sure I understand it: Your husband is divorce, and has a daughter with his ex-wife, who would be your step-daughter. Your husband has been deployed, and his ex-wife will permit visitation with your husband's mother, but not with you and your daughters. YOu ask whether you have a legal remedy to visit with your step-daughter. The custody order is in a Michigan court.
A step-parent has no legal rights to parenting time (visitation). Your ability to visit would normally be up to your husband; however, he is not here to permit or arrange for the visits. A possible remedy would be through your husband's mother. Grandparents may seek an order for grandparenting visitation rights under some circumstances. There is a presumption that a fit parent may deny grandparenting visitation, but the grandparent the Court can overturn that presumption. The court will make that determination based upon the best interest of the child. If If your husband's mother obtained an order allowing her visitation, then she could allow you and your daughter visitation. If your husband's ex-wife objected to grandma allowing you visitation, then grandma could seek an order permitting it.
The statute you may want to review is MCL 722.27b.
