(b) In making a determination under Subsection (2)(a), the court shall:
(i) allow the parties to submit information; and

(C) the distance between the court in this state and the court in the state that would assume jurisdiction;
(D) the relative financial circumstances of the parties;
(E) any agreement of the parties as to which state should assume jurisdiction;

(H) the familiarity of the court of each state with the facts and issues of the pending litigation.

(4) A court of this state may decline to exercise the court's jurisdiction under this chapter if a child custody determination is incidental to an action for divorce or another proceeding while still retaining jurisdiction over the divorce or other proceeding.
