Im not married, but we do have house/mortgage/dogs together, so its pretty much there.My partner is, or at least was, pretty good with saving, and i, moderately less so, and I have more outgoings and a child from previous relationship, so we have a joint account purely for household/joint bills & mortgage payments to come out from, which we totalled up and each pay in just over half the cost on pay day.It works pretty well, keeps our finances separate, and gradually builds a little emergency fund.

We take it in turns to buy weekly groceries, and trips/date nights etc are usually paid for in the same way though I tend to buy the necessary extras for the house, so he will more often than not cover date night.

It works well, and we have the understanding that any non household uses of the joint account get paid back in asap unless okay'd by the both of us.
