Rich...I imagine the number of hoops you have to jump through would depend on whether there is a mortgage...are you subdividing a parcel...does your dad have a clear title...etc. I would think that if there isn't a mortgage...and there are no chenges to the current title other than the name change...it shouldn't be too difficult. However...I personally would still contact a real estate attorney...if for nothing else than to provide peace of mind.
On another note...I read about your current difficulties in the other thread. I hope things work out for you...and for the family business!!!
