Not married yet, though we have been living together for a number of years, pretty close to "common law married" ...
Me: Checking account, Brokerage/Stock holdings, 401K, 2 Credit cards
Her: checking account (its been suspended though, she isnt working, and gave whatever she had in there to her mom) , 1 credit card (my card, but got her added to it so she could buy gas and groceries and spend my money when I am at work.)
I pay all the bills & mortgage.
She is smart with spending, usually finds coupons, buys garage sale stuff, etc.
