We both want to keep it out of court where possible, neither of us are wanting to make it messy for the sake of our daughter!
As for selling, the mortgage that I could get on my own wouldn't be much, so it would be a considerable downsize (which, when you live in a shoe box already isn't great) plus there would be very little equity in the property anyway as the deposit was payed for by the father in law, which I am still paying back, so I would have to clear that debt leaving me with nothing to put into a new place.
Thank you for your help guys, it is appreciated!!
