My brothers wife kicked him out last July and announced in November when she moved out of the home they shared she was with someone else and moved in with him in February we suspect he was around before November(my brother took over the tenancy and moved back into the house). What does he need to do to start permanently being separated as we do not know where to start he is on benefits so don't know if he has to start divorce proceedings. They have a 5 year old daughter who goes between both of them. Thank you for any advice.
