We opened a joint account after we got married. All our salary goes to this account and all bills are paid from this account My husband moved into my house and we rented out his house (we did that because I own a single house and his is a 2-unit duplex, it is easier to rent out both sides of duplex and would generate more rent) We have added both of our names to each house. So far it works really well, we have never argued on money.
