It depends on whether there is a court ordered parenting plan or residential schedule. If there is a court order, then you must file a Notice of Intended Relocation and a proposed parenting plan that will accommodate the long-distance nature of the move. Otherwise, if there is no court ordered parenting plan, it would be the best practice to notify the other parent of the move, at a minimum. The father does have rights to the child, and he may file a court action at any time. For this reason, I think it is always best to protect oneself and obtain a parenting plan. While the two you have never been married, you conceived a child together. Consequently, to obtain a parenting plan or residential schedule, you would file a parentage action. You should consult with an attorney about the specifics of your case to get more concrete advice and an explanation of the pros and cons for all the options available to you, including the filing of a parentage action.
