So two of my best friends and I rented this apartment last year. After a few weeks, one of them left town.
So we rented her room to this guy and made a 10-month contract. The contract was over last month and we never renewed it.
But now my best friend is coming back to sydney next month and she wants to live with us again. (yeah the apartment is under her name as well and she still has all the furniture and stuff in her room which the other guy is living in)
So I nicely asked the tenant to move out next month cuz the girl who stayed there before is coming back. But then he was so mad and started picking on everything i said. He said he's not gonna move out and that I can't kick him out for no reason. And he also said his father is a lawyer and he would go to the court if we forced him to move out.
I know nothing about the law. I'm a very nice guy so I couldn't fight or argue back to him. I pretty much just listened to his yelling and told him i would think about it. But the contract is already over and I'm not telling him to move out right now. I'm telling him 4 weeks in advance.
Please give me some advice.
