my Wife has always managed the finances in our marriage. i’m retired now but my paycheck has been direct deposited into our joint checking account ever since direct deposit became a thing. Before that i’d endorse the check and give it to Her to deposit. It is a joint checking account but She has the checkbook and i’m not allowed to write checks. As my career advanced, our finances became more complex as i became a shareholding partner in my firm, had inheritances, etc…but She always directed me in handling $$$ and i had to do what i was told. Now my Social Security check is direct deposited.
i get an allowance for daily expenses, and if i want to buy anything big i have to ask Her. i do have a credit card but She gets a detailed statement every month and She goes through it carefully, so i can’t use the card casually and would have to explain any charges.
