(a) If a court of this state, on written motion of a party, finds that in
the interest of justice and for the convenience of the parties and witnesses a claim or action would be more properly heard in a forum outside this state or in a different county of proper venue within this state, the court shall decline to adjudicate the matter under the doctrine of forum non conveniens. As to a claim or action that would be more properly heard in a forum outside this state, the court shall dismiss the claim or action. As to a claim or action that would be more properly heard in a different county of proper venue within this state, the venue shall be transferred to the appropriate county. In determining whether to grant a motion to dismiss an action or to transfer venue under the doctrine of forum non conveniens, the court shall give consideration to the following factors:
(1) Relative ease of access to sources of proof;
(2) Availability and cost of compulsory process for attendance of unwilling witnesses;
(3) Possibility of viewing of the premises, if viewing would be appropriate to the action;
(4) Unnecessary expense or trouble to the defendant not necessary to the plaintiffs own right to pursue his or her remedy;
(5) Administrative difficulties for the forum courts;
(6) Existence of local interests in deciding the case locally; and
(7) The traditional deference given to a plaintiffs choice of forum.
(b) Acourt may not dismiss a claim under this Code section until the defendant files with the court or with the clerk of the court a written stipulation that, with respect to a new action on the claim commenced by the plaintiff, all the defendants waive the right to assert a statute of limitations defense in all other states of the United States in which the claim was not barred by limitations at the time the claim was filed in this state as necessary to effect a tolling of the limitations periods in those states beginning on the date the claim was filed in this state and
ending on the date the claim is dismissed.
