My sister says he's kept my bedroom exactly the same from when I was last there 3 years ago. I want to smash it all up because I left after a fight and I don't want him keeping my things like that. It's creepy and they need to be thrown out and broken. Can I do something legally that will let me do that?

I asked this question before and everybody was really unhelpful. I've spoke to him but he wouldn't let me into his house. IF I CAN FORCE MY SISTER TO GIVE ME HER KEY, CAN I LEGALLY GO IN AND SMASH THINGS?

I DON'T WANT TO REMOVE MY THINGS. I WANT TO SMASH THEM IN HIS HOUSE SO DON'T BOTHER MENTIONING IT.

WHO CAN HELP ME WITH THIS?

I found out he also has my passport. IT MUST BE ILLEGAL FOR HIM TO HOLD HIS SON'S PASSPORT HOSTAGE. HOW DO I GET THAT BACK TOO?
