Ex and I have shared care of DD, we each have her 7 nights out of 14. It's a flexible arrangement, and one that all three of us are happy with.
He doesn't pay any maintenance, he buys most of her clothes and we each pay half for trips, camps etc. I pay the childminder and school lunches.
He has no mortgage as house is owned, I pay rent as I chose to move out. When I saw the solicitor and discussed finances, he was surprised that ex doesn't pay maintenance.
Am I wrong in thinking that as we have shared care he doesn't have to?
