If you are married, how do you and your significant other do your bills?
A certain amount of your money goes into a joint account then the rest in split accounts? Both pay the mortgage lenders or pay the rent, and take care of the additional miscellaneous bills?
I am getting this matter straightened out before marriage. *kilig* If both agree, income goes into one pot, pay bills, equal allowance and put some away for rainy days. 
Hubby and I had this same discussion before we got married, both agreed to split everything 50/50. So right after we said “I do”, we opened a joint checking account, that way all of our bills will be paid from that account. This prevents us from fighting over finances. And oh by the way, we also opened a joint savings account for the rainy days
