Hi…My mother died in Sept 2015. I am the sole heir to the mineral rights she has in Nueces County. When do the royalties/mineral interests officially transfer to me? My sister the executor has been silent and has not told me anything concerning what she has done or is doing in regards to my mineral royalties. I have had to contact the oil company myself and found out my sister did a W-9 in November to transfer the royalties to the estate. Is this correct?
