Not 100% sure but think you have to re register the parcel under your name - you can do this online along as you know your parcel number (Should be able to find it online at your County Assesors GIS Maps ) I think only one LOT can be used per parcel number, so if your dad is registered in the system for that parcel, you might have to call the DNR and redo it (only took me 5 minutes on the phone ), someone correct me if Im wrong it’s been a while .
