Indiana Code Title 29. Probate § 29-1-6-5

Sec. 5. The court in which a will is probated shall have jurisdiction to construe it.  Such construction may be made on a petition of the personal representative or of any other person interested in the will;  or, if a construction of the will is necessary to the determination of an issue properly before the court, the court may construe the will in connection with the determination of such issue.  When a petition for the construction of a will is filed during administration of the estate, notice of the hearing thereon shall be given to interested persons.  If the estate has been closed prior to the filing of such petition, notice shall be given as in civil actions.
