There are no "odds"—this isn't Vegas. It depends on the judge, and how they feel about the reasons offered for the move. If your ex has not been very involved in child's life...that is, has not used most of his current parenting time and you are able to prove that, the judge may be more favorable to the move. If you present a viable long-distance parenting plan where your ex still has about as much time as he currently has, you should be OK. If he currently has four days a month (EOW) and two weeks in the summer, you may have to offer six-seven weeks in the summer, and time over major holidays. Could you afford the cost of transporting your child back and forth? That may be part of the requirement, too.
