Joint tenant has left

Hey everyone, I’ve kind of posted this already but I couldn’t seem to find a definitive answer. A joint tenant has vacated the property but is still on the tenancy until august, we are not on great terms and they have left a few bags of rubbish and some personal items they didn’t want behind. I have read online that on a joint tenancy no tenant has exclusive right to any part of the property, am I ok to move their bits into the smaller room and I take the bigger one? Is there any legality’s I need to be aware of? Thank you
