My mother in law has got involved with a great gaping arsehole of a man. He moved into her house (owned, mortgage free) during lockdown and has since revealed himself to be emotionally and I think financially abusive. He has her convinced that if he pays for anything more than a bit of food shopping or lifts a finger around the house he will have a claim on the property. She now believes that as he’s been there for more than 2 years she will have to pay him to move out. I do not believe this is the case, can any legal experts clarify?
