With regard to bank accounts, it is important to discuss with your lawyer every bank account you have, whether titled jointly with your spouse or in your sole name, or jointly with someone else, and come up with a strategy for each of those, depending on the purpose of the account. As for credit cards, it is always important to keep a close eye on the expenditures that the other spouse is making on jointly titled credit cards, or cards that are held in your name, which you can of course do online, and to share that information with your attorney.
