I’m not talking about each person having a small account on the side for discretionary spending or as a holdover from pre-marriage times. I’m talking about NO shared bank account. Person A deposits into one bank account what Person A makes and Person B deposits into another bank account what Person B makes. Bills are divided up so that each is responsible for paying a certain segment. Sometimes it goes as far Person A and Person B having absolutely no idea or access to what the other earns.
My wife and I have a theory that married couples keeping separate bank accounts is a fundemental problem in the marriage and a strong indication that the relationship will not last. If you can’t trust your SO with money, well…what can you trust him or her with? We know of at least two couples like this. One ended in a divorce last year. One seems to be going along well, for now.
For the purposes of this question, you can assume it means you if you’re in a long term monogamous relationship but unable to marry due to the laws in your jurisdiction.
