My mother recently passed away. She had inherited some leases from my father, who inherited from his mother, who inherited from my grandfather. These are primarily located in Illinois with one located in Oklahoma/Canadian County, Oklahoma (Wehlu). I know that some in IL are producing as my mother was receiving checks. I need to do some research on the others (again) to see who is working the wells and if they are holding onto royalty checks. I know the state of IL is holding on to some past checks as the companies weren’t aware of the previous deaths. It’s a bit of a mess. I have 3 sisters. We each are receiving 25% of the estate. I’m trying to understand how difficult it’s going to be to get these leases split up. I’m sure IL has different property laws from OK. Also, given the size of each, wondering if it’s worth the effort and money. Any insight is appreciated.
