I can give a bit of a reason why. Maybe one of the attorneys can give some direction for getting a death certificate. The title opinion that is done for leasing is not quite as rigorous as the one for the Division Order. Leasing money is small in the big scheme of things, but the royalty payments are in the millions, so have a new title opinion and require a high level of proof of heirship. If Cimarex has paid you royalties before, perhaps they can be approached again. I know that it is was very hard to get even simple death certificates in the last few months for me.
