We have separate bank accounts.

We both lease a motor vehicle each which I like as the cost incorporates new tyres, servicing as per log book requirements, insurance, petrol, the vehicle itself, rego etc - so when time comes for those to be paid out there is no need to dip into savings or anything as all the money is in the kitty.

I am the 'saver' so I put money into our holiday and kids schooling accounts, and I pay the rent.

DH pays the utilities and usually for most of the groceries too unless I happen to do a little food shop here or there (we do a few shops each week instead of one big shop. And we buy a lot in bulk when things are on special too).

This works really well for us, we've never had any $$$ issues, but we do both make good $$$.
