My wife/her family own mineral rights in a Washita County quarter section (~160 acres) with interests split in three 25% pieces plus three 8-1/3% pieces. In the past (mostly prior generation holders), leases and bonus payments have been executed by just one or two of the parties (max 50% interest) apparently without contacting the other parties.
Is it 'legal' or common practice for lessee to only contact a minority (up to 50%) of the owners?
Does the lessee have an obligation to contact other owners? Does the lessee have obligation to pay bonus to other owners and execute similar leases?
I think I know the answers but I'd like to have comments from more knowledgeable members. The family is planning to act/negotiate together in the future on any upcoming lease offers.
