Ind. Code § 30-1-6-1
Administrators and executors of estates of deceased persons and guardians of the estates of persons under eighteen (18) years of age and incapacitated persons (as defined in IC 29-3-1-7.5 ) are authorized to execute oil and gas, coal, or other mining leases upon the lands belonging to the estates of the deceased persons, or of persons under eighteen (18) years of age or incapacitated persons, for a term not to exceed ten (10) years and as long thereafter as oil, gas, coal or other minerals may be produced in paying quantities, upon compliance with this chapter. The court having probate jurisdiction in the county in which the guardianship or administration proceedings are pending shall have jurisdiction to order the sale for execution and delivery of a lease or leases upon the filing of a petition alleging that the estate of the deceased person or the estate of a person under eighteen (18) years of age or a protected person is the owner of the lands described in the petition, and that the lands have a probable value for oil and gas, coal or other mining purposes, stating the probable value of the proposed lease, and that the estate of the deceased person or of the protected person is not financially able or that it is impractical for the estate to explore and develop the land for oil and gas, coal, or other minerals, and that it is to the best interest of the estate to lease the lands. The petition shall be verified by the administrator, executor, or guardian, and if it involves lands belonging to the estate of deceased persons, the petition shall set forth the names and post office addresses of the heirs of the deceased persons. If the will of any deceased person empowers the executor to sell oil, and gas, coal, or other mineral leases upon the lands of the testator, it shall not be necessary for the executor, or the administrator with the will annexed, to comply with this chapter. The word "land" or "lands" includes any oil, gas, coal, or other mineral rights or interests in lands which may be leasable.
