We have no dependant kids, and would do this a bit differently if we did.
We have individual overseas income and that is paid into a non-interest bearing joint account, and promptly transferred to our individual current accounts (this is a PITA, but our accounts are with a building society which doesn’t accept overseas payments). Our British pensions are paid into our individual accounts. We each transfer an amount proportionate to our income to an interest paying joint current account (with a different building society) to cover household costs including food, bills, house maintenance, the odd weekend away, birthdays, Christmas and so on, and also savings for holidays, replacing household appliances etc. We tend to review how much we each pay every April.
We have our own current accounts, out of which we pay for our own hobbies and interests, car running costs, each other’s birthday and Christmas presents, and every day personal costs - hair, gym, clothes and such.
In practice, this isn’t as rigid as it sounds. One of us will often pay for something for both of us, or for the other, and we don’t pay each other back, or keep track, because it’s all really just our money.
We have individual savings accounts, because no joint ISAs are allowed, but we know what’s in each others, because again, in practice, it’s our money.
Our accounts are spread over several banks, so your husband working at the bank where we hold any of them would have no clue about how we manage our finances.
