My dad died w/o will, his wife was appionted executor in probate court in Tennessee over 18 months ago. Just found out she gave someone else power of attorney for selling property, vehicles etc of the estate. She did not notify myself or sister, legal heirs, or the court. Can she do this without going through the probate court since they appointed her executor? Most all the vehicles, boat, plane and travel trailer were titled and registered in Georgia. Dad had 2 properties in Ga and 1 in Tn. This person is selling things at extremely low prices, ex: 1960 Corvette for $1000.00
