Soince you haven't mentioned any legal separation or custody orders, I assume you mean that you and your husband physically separated a year ago, but have not obtained a legal separation through the court. If this is true, there's no law prohibitig your husband from letting his parents care for the child during your informal parenting agreement. Courts don't have jurisdiction over families that have not brought their custody dispute into court for settlement. If one of you decides not to allow your child to be with the other parent--for whatever reason--the only way you can untimately resolve it is to go to court to obtain a custody order as part of a legal separation or a divorce.
