For those that are married, there are two ways to operate the financial accounts of the household. You can choose to operate it individually or as a team. When I do get married, I will prefer going as a team. It is easier and balances the expenses.
We have a joint account in one of the bank here where we also have taken a locker on rent. We have a joint account here so that anyone us may operate locker anytime.
I don't have a joint account with my spouse. We keep our money separately, it is usually me who pays the bill and she saves for financial emergencies. Sometimes she also helps me when making big purchases.
