Ind. R. Civ. P. 78
Whenever a court has granted an order for a change of venue to another county and the costs thereof have been paid where an obligation exists to pay such costs for such change, either party to the cause may file a certified copy of the order making such change in the court to which such change has been made, and thereupon such court shall have full jurisdiction of said cause, regardless of the fact that the transcript and papers have not yet been filed with such court to which such change is taken. Nothing in this rule shall be construed as divesting the original court of its jurisdiction to hear and determine emergency matters between the time that a motion for change of venue to another county is filed and the time that the court grants an order for the change of venue.
