Ind. Code § 30-1-6-2
Upon the filing of a petition under section 1 of this chapter, the court in its discretion and upon showing of benefit to the estate of the decedent or protected person shall make an order authorizing and directing the administrator, executor, or guardian to sell a lease upon the lands for oil, and gas, coal, or other mining purposes. The sale may be either public or private as the court may direct and upon notice as may be fixed by the court in its order of sale. Should the court determine from the petition that the sale price of the lease would not be sufficient to justify the giving of notice of sale, the court may order the lease sold without notice. Any sale of oil, and gas, coal leases, or other mineral rights under this chapter shall be on a royalty basis and bonus if any. The bonus shall be payable in cash at the time of the execution and delivery of the lease or on terms as the court shall deem just and proper. Where an estate is solvent, no administrator or executor may lease land as provided in this chapter unless the administrator or executor is joined in the lease by the heirs, or their guardians if the heirs are under the age of eighteen (18) years or incapacitated, of the deceased person whose estate is being administered. If the lands to be leased are situated in any other county than that in which the probate proceeding is pending, then the notices of sale, if any are to be given, shall be published and posted in the county of the location of the lands.
