(2) On receipt of the notice described in division (I)(1) of this section, either parent may apply to the court for a hearing to expedite an allocation or modification proceeding so that the court can issue an order before the parent's active military service begins. The application shall include the date on which the active military service begins.
The court shall schedule a hearing upon receipt of the application and hold the hearing not later than thirty days after receipt of the application, except that the court shall give the case calendar priority and handle the case expeditiously if exigent circumstances exist in the case.
The court shall not modify a prior decree allocating parental rights and responsibilities unless the court determines that there has been a change in circumstances of the child, the child's residential parent, or either of the parents subject to a shared parenting decree, and that modification is necessary to serve the best interest of the child. The court shall not find past, present, or possible future active military service in the uniformed services to constitute a change in circumstances justifying modification of a prior decree pursuant to division (E) of this section. The court shall make specific written findings of fact to support any modification under this division.
