Thank you for submitting your question regarding whether or not you have any authority to assert who your wife can expose your child to.  Your situation is very common among divorcing couples with children.  Once a marriage has ended parents worry about their child’s exposure to another mother or father-type figure.  The courts on this matter will vary from state to state.  However, there are some common themes seen throughout all state courts.Courts focus on setting up child custody with the intentions that everyone is working towards the best interest of the child.  Sometimes parents have different views on what those best interests are, and more often than not the parents confuse their best or preferred interest with what is in the best interest of the child.  However, courts are willing to draft custody orders with specific details to protect the best interests of the child.  If you already have a child custody order in place, you can petition the court to modify the custody order.  If you do not have a child custody order, you should petition the court to create an order for child custody.  Within either the modification or new order, you can request to include that the visitation of the parent with the child will not be permitted if the parent has an unrelated, opposite gender individual is within the residence of the parent.  If this language is contained within your order and your wife decides to violate this order, then you can request that the court hold your wife in contempt of the order.
