My sister is trying to separate from her partner. He moved into her house two years ago. The house is in her name and all furniture and furnishing also belong to her (basically, he moved in with his clothes and his credit card debt). She pays the mortgage and all associated expenses. Although he has recently become employed for most of this time period, he has been out of work and she has basically supported him, paid all expenses and even paid off the amount owing on his car. Due to his controlling behaviour, the relationship has broken down and she has asked him to leave but he is refusing to leave. He is emotionally abusive and I am concerned it will escalate into physical violence. He has started waking her up at all hours of the night screaming at her, slamming doors and last night spat in her face. Please tell me where she stands under family law and with regard to his entitlement to any of her property as he is threatening to take 'half of everything' that she has worked so hard for.
