My question involves personal property located in the State of: Kentucky

My boyfriend of ten years left about two months ago. We lived together, no agreement or anything. It is my house and I am the only owner. He left all his stuff, including vehicles.

I have research abandoned property laws but can't find any specifically for Kentucky. I'm looking for help to see, can I write him a note telling him how long he has to get his stuff or I will keep it/sell it? What am I supposed to do with the vehicles, they have taxes owed on them and one of them is not even paid off.

Thank you!
