We have one account for everyday needs, and another for our long term savings. About a week before we got married, we closed her account and put it all into one. Now, she doesn't work, so she wouldn't have her own account anyway. We don't really "budget" but our system works for us. Neither of us spend a ton of money. We make no big purchases without discussing it. I check the balance regularly online and let her know where we are. We hide NOTHING from each other financially (or otherwise for that matter). I tell her when I get cash bonuses or exactly how much I get when I take all the scrap wire into the recycling plant. She knows the account number and password to the accounts. Accountability, honesty, and openness is our key.
