My wife and her sister became naked owners of some Louisiana oil and gas leases when their father died, with a will, leaving all property to my wife's step-mother. No ancillary succession proceedings had been filed in Louisiana.
Some years later, the step-mother, was awarded a Judgment of Possession(JOP) in Louisiana for these leases.
It is now some years after that, and the step-mother with the JOP has died.
My question is: Do the naked owners (the step-children) still retain heirship rights to the leases, or did they lose their heirship when the JOP was granted to the step-mother. Do the rights to the leases go to the beneficiaries of step-mother only?
Or can my wife and her sister open a succession in Louisiana for the step-mother and gain a partial possession by a naked ownership.
