When I decided to leave my husband, but before I found a rental to move to. So for about a month. But I think Centrelink put a time limit in it.
Then 18 months later when exhusband still hadn't moved out of our marital home, even though he was meant to be out after 6 months. Myself and the kids moved back in. Seperate rooms. I had to get written statements from several friends to state that we weren't a couple. I had a new partner anyway. We paid half the mortgage each. I did that for 6 months and he still wouldn't move out, so I move out again.
So yes it can be done. I've known other people to do it too. Share the house and care of the children but that's it.
