Not actually my ex, but anyway. My friend and her partner broke up a few months ago. Was a fairly amicable split to start with. They have 2 DC ages 8 and 11. The ex started seeing someone else straightaway, not a very stable person by the sounds of it, and has now lost his job and moved in with new GF and her young kids.
He recently called to ask if he could move back in with my friend (his former partner) if things go wrong with his new GF. My friend said no way, but is worried that legally he might have a right to do this. They share a mortgage on the house she and kids are living in. He is still paying the mortgage but making absolutely no other financial contribution. It would be very distressing for the DC who currently see him once a week and every other weekend.
Would he be able to move back in to the house against her will?
