If I'm saving in a joint account with my partner, does it count as genuine savings if I'm buying by myself?

Buying together: no drama

If you and your partner are both on the loan, a joint savings account is the simplest thing in the world. It's both of yours, the bank can see the pattern, and the whole balance counts toward your genuine savings.

That's the clean version. The questions only start when the account has two names on it and the loan has one.

Buying solo: proving what's yours

If your partner isn't on the loan, the bank can't just assume the whole joint balance is yours. We're generally going to need to show which portion of that money you actually put in. In practice that means pulling apart the deposits going into the account and matching them to your pay.

The cleaner your records, the easier this is. If your pay goes in and your partner's pay goes in, we can usually show your share. If money moves around between a few accounts, it takes more work to tell the story, so it's worth tidying up before you apply rather than after.

The relationship question

Here's the bit people don't expect. If you're buying separately and you've got two account names on there, the banks are going to go, hang on, you're in a relationship. That matters because a relationship changes how they look at your household expenses.

Most lenders start by assessing you on couple living expenses, even if your partner isn't on the loan. So we need to go with a lender that's going to support treating you as single, or apportioning your household expenses between you and your partner. It's fine, it's just something to be very mindful of, because the wrong lender can read your expenses in a way that knocks your borrowing power around.

Where the banks actually split on this

On the savings, most of the panel says the money has to be held in the name of at least one borrower, so on paper a joint account with you on it qualifies. One of the big banks spells out that joint funds are fine as long as at least one account holder is on the loan. A couple of the big banks go the other way: their top tier of savings has to be held only in borrowers' names, which on its face rules out a joint account with your partner. What none of them write down is how much of the balance counts as yours, the full amount, half, or only what you can evidence. That's a question for the lender, which is why I prove your share rather than assume it.

On expenses, it's more than a couple of lenders but far from all. A handful will split household expenses by your share of the household income, and a few will treat you as a single adult if your partner earns enough on their own. The catch is your partner has to hand over paperwork: a signed consent form, ID, their income documents, and at some lenders a credit check. At least one lender has no way to split expenses at all.
