I have joint custody with my ex who just drops off our 5-year old child at his mom's during the school week and picks her up at 10 pm. He does not supervise her homework or her personal hygiene. Can I revise this custody arrangement?
You can petition the courts for a change in the custody agreement. Arrangements and visits can be modified, but the reasons do vary from state to state. If you want to win, you need a lawyer to prepare the case for you -- or at least counsel you on how to proceed.
