who is responsible for HOA fees when condo is paid for, owner deceased and no will.

My wifes son passed 2 years ago as of this last Dec 23. There was no will leaving the condo to anyone and theres really nothing of value (everything had roaches, fleas or covered with second hand smoke). The title is in his name and the unit is paid for. The manager at the complex has made contact with us when we've gone over to look and sort through things. She believes since my wife was the tenants mom she is responsible for the HOA fees. We paid for the first four month after his death and then quit. We are looking at taking this to probate. In Florida who is responsible for HOA when there is not a will leaving it to someone or a listed heir?
