Joint accounts are fine if that’s what people want.

His, hers and ours works as well and for some people it’s better as you get a degree of financial privacy within the relationship. We each contribute to the joint expenses, each get to spend on personal stuff with limited accountability and get to invest separately. My wife and I have been doing this for about ten years now and neither of us want it any other way. It helps that we both spend less than our income and have fairly similar financial outlooks. That said, the his and hers parts are very open – we discuss where we are on a regular basis, discuss investments and keep a consolidated balance sheet to track financial progress.

The biggest advantage of this approach is we each get to lie about how little we spent on each other’s birthday presents without getting called on it
