Family member has just been through this in family court.
She doesn't work due to a disabled DC, lives on benefits due to DC, has zero savings.
Exh has his own business but hides his real earnings, cash jobs, think building trade.
The court wasn't interested in what happens to her, the fact that shes going to be potentially homeless with a disabled child, house sale will not leave her enough to buy something else, she can't get a mortgage, she actually owned the house before she met the Exh and has been paying the mortgage since he left 6 yrs ago.
It was a straight split 50/50.
She was actually accused in court of financial abuse of her DC as the DC'S PIP etc is used to pay their household bills.
Exh doesn't see DC and gives no respite.
Was told in court that she had to "maximise her earning potential", she replied that dc was disabled and couldn't be left alone, she was told again to "get a job"
I'd base my future plans on a 50/50 split if I were you.
Courts do not like Mesher Orders, they like a clean break
