Depending on the facts of the case, it may be a good idea to get your name off of any joint accounts as soon possible so that the other side cannot withdraw funds or charge those accounts. One exception might be is if the money is brought into the account by the other party and you need to use those funds. Otherwise, it’s often a good idea to separate accounts quickly unless a) the other party is the income producing party and you need access to those funds; or, b) creating separate accounts would telegraph the other party that a petition is shortly going to be filed, and you do not wish the other side to know quite yet.
