Indiana Code Title 29. Probate § 29-3-13-2

Sec. 2. (a) This subsection applies to a guardianship of the property of a minor.  If no guardian has been appointed, and no petition in a guardianship proceeding is pending in Indiana, a guardian appointed by a court of another state in which the minor is domiciled may file, with an Indiana court in a county in which property belonging to the minor is located, an authenticated copy of the guardian's appointment and a bond that meets the requirements of IC 29-3-7-1 with respect to that part of the property of the minor that is located in that county.  After filing the copy and bond, the foreign guardian may exercise as to the property of the minor in that county in Indiana all powers of a guardian in Indiana and may maintain actions and proceedings in Indiana.

(b) In the case of an incapacitated person who is an adult (as defined in IC 29-3.5-1-2(1)), a foreign guardian for that adult may register certified copies of the guardian's letters of office and order of appointment under IC 29-3.5-4.
