abandoned property laws in NY??

While I sympatize with it being difficult for him this is part of how I pay my bills and my creditors don’t care how I come up with the money to pay them so I don’t have the luxury of just letting the unit sit while he figures shit out. I actually have a 1 car garage with nothing in it at that property that I could put her items in. I just want to make sure I can legally do that before I open myself to a bunch of liability.
