Joint bank account: pros and cons

How a joint bank account works

It's a checking or savings account with two owners. Each of you gets a card and full access: either one can pay, withdraw, or send money without asking the other. The bank treats both of you as owners of the whole balance.

Who actually owns the money is a separate question. In many US states, while you're both alive, the money belongs to each of you in proportion to what you put in, even though the bank lets either of you take it all. When one owner dies, a joint account usually passes straight to the survivor without probate. In the UK it works much the same way, and the bank won't step in if you disagree about whose money it is.

The pros

• Shared bills come from one place. Rent and utilities on autopay, the joint card for groceries: nobody fronts money and waits to be paid back.
• You both see everything. Balance and transactions are in the bank's app, so there's nothing to ask about.
• It's simple. Each of you puts in your share at the start of the month, and the account does the rest.
• On death, the survivor keeps access. That's a real advantage when there are bills to pay in the weeks after.

The cons

• Either of you can empty it. A breakup, a fight, or just a bad decision, and the balance can be gone in a day. Getting it back is a matter for lawyers, not the bank.
• Debts can reach it. A creditor who wins a judgment against one of you may be able to freeze or garnish the account, depending on your state.
• Your money gets mixed. After a few years of deposits from both, working out who put in what is hard.
• In the UK, it links your credit files. Once you share an account, lenders can look at your partner's history when you apply.
• Less privacy. A birthday gift paid from the joint account isn't much of a surprise.

Deposit protection works per owner: in the US, the FDIC covers a joint account up to $250,000 for each co-owner, and in the UK the FSCS covers £120,000 per person at each bank.

A worked example

Take-home pay of $5,000 and $3,500 a month, shared costs of $2,720. Splitting by income, one of you puts in $1,600 and the other $1,120, about 59% and 41% (the split bills by income calculator does this in a minute).

Now say the higher earner also leaves $500 a month of personal savings in the joint account. After a year there's $6,000 extra, all from one person. Legally it may still be theirs, but the other partner can withdraw it, and if you split up, the person who saved it has to prove it was theirs. Bank statements help, but after a few years of mixed deposits, untangling them is hard.

Alternatives to one shared account

A joint account isn't the only way to handle shared money:

• Three accounts: each of you keeps your own, plus a joint one that only gets the money for shared bills. Little sits in it, so there's little to fight over.
• Two accounts and a running balance: each of you pays from your own account, and an expense sharing app for couples keeps track of who owes whom. No account to open or close, and personal spending stays personal. To pick one, see our guide to expense sharing apps, and if you're coming from Splitwise, the Splitwise alternatives.

Which one to choose

• Steady bills and similar incomes: a joint account is convenient.
• Very different incomes, or savings that belong to one of you: three accounts, with only what you need in the joint one.
• No appetite for a new account: keep your own and use an app to track the balance.
