Today Discussion (Joint Account Issues Between Spouse)

My friend narrated her experience over joint account with her spouse, how she always finance the account and one day to her greatest surprise she when to the bank request for the statement of account only to be told by the cashier the account was in a red state. She was so disappointed. I have hear of this experiences before how men are not good at keeping money (means they are on the spending side). So on this tell me how do you see joint account between spouse. Let me know your stake on that
