Indiana Code Title 30. Trusts and Fiduciaries § 30-4-6-7

(a) In any proceeding under IC 30-2-14, IC 30-2-15, or this article, any petitioner or other interested person, including but not limited to a trustee or beneficiary, may file a copy of the trust instrument for the trust with the court, to make the trust's terms a part of the court's records.  If there is a dispute about whether the trust has been amended or restated or about which version of a trust instrument is a valid version, two (2) or more parties may file copies of different trust instruments or amendments so that the court is aware of their contents.

(b) Permissible methods for filing a copy of the trust instrument with the court under subsection (a) include filing the copy as an exhibit or attachment to a petition for substantive relief under this article.  A separate petition to “docket” the trust or to permit the filing of a copy of the trust instrument is not required.

(c) Upon the filing of a copy of the trust instrument with the court, a presumption arises that the trust's terms have been properly presented to the court.  The presumption may be rebutted on a showing that:

The filing of a copy of a trust instrument under this section does not preclude any interested person from asserting claims or defenses regarding the validity, interpretation, or administration of the trust or from cross-petitioning for relief under this title.

(d) If:

the court may order any party to file a copy of the trust instrument as a condition to entertaining or hearing a petition for substantive relief with respect to the trust.

(e) The filing of the trust instrument under subsection (a) shall not result in continuing supervisory jurisdiction by the court.  Upon conclusion of the proceeding, unless otherwise ordered by the court, the clerk shall remove the trust instrument from the court's records.
