Section 801.63 - Stay of proceeding to permit trial in a foreign forum(1) STAY ON INITIATIVE OF PARTIES. If a court of this state, on motion of any party, finds that trial of an action pending before it should as a matter of substantial justice be tried in a forum outside this state, the court may in conformity with sub. (3) enter an order to stay further proceedings on the action in this state. A moving party under this subsection must stipulate consent to suit in the alternative forum and waive right to rely on statutes of limitation which may have run in the alternative forum after commencement of the action in this state. A stay order may be granted although the action could not have been commenced in the alternative forum without consent of the moving party.(2) TIME FOR FILING AND HEARING MOTION. The motion to stay the proceedings shall be filed prior to or with the answer unless the motion is to stay proceedings on a cause raised by counterclaim, in which instance the motion shall be filed prior to or with the reply. The issues raised by this motion shall be tried to the court in advance of any issue going to the merits of the action and shall be joined with objections, if any, raised by answer or motion pursuant to s. 802.06(2) . The court shall find separately on each issue so tried and these findings shall be set forth in a single order.(3) SCOPE OF TRIAL COURT DISCRETION ON MOTION TO STAY PROCEEDINGS. The decision on any timely motion to stay proceedings pursuant to sub. (1) is within the discretion of the court in which the action is pending. In the exercise of that discretion the court may appropriately consider such factors as: (a) Amenability to personal jurisdiction in this state and in any alternative forum of the parties to the action;(b) Convenience to the parties and witnesses of trial in this state and in any alternative forum;(c) Differences in conflict of law rules applicable in this state and in any alternative forum; or(d) Any other factors having substantial bearing upon the selection of a convenient, reasonable and fair place of trial.(4) SUBSEQUENT MODIFICATION OF ORDER TO STAY PROCEEDINGS. Jurisdiction of the court continues over the parties to a proceeding in which a stay has been ordered under this section until a period of 5 years has elapsed since the last order affecting the stay was entered in the court. At any time during which jurisdiction of the court continues over the parties to the proceedings, the court may, on motion and notice to the parties, subsequently modify the stay order and take any further action in the proceeding as the interests of justice require. When jurisdiction of the court over the parties and the proceeding terminates by reason of the lapse of 5 years following the last court order in the action, the clerk of the court in which the stay was granted shall without notice enter an order dismissing the action.(5) Motions under this section may be heard on the record as prescribed in s. 807.13 .Sup. Ct. Order, 67 Wis. 2d 585, 612 (1975), 758, 777; 1975 c. 218; Stats. 1975 s. 801.63; Sup. Ct. Order, 141 Wis. 2d xiii (1987); Sup. Ct. Order, 151 Wis. 2d xvii (1989). A motion to stay a Wisconsin action or transfer the case to an Iowa court where an action arising out of the same accident was pending was properly denied when the parties were different and because of Iowa law the plaintiff would lose substantial rights. Littmann v. Littmann, 57 Wis. 2d 238, 203 N.W.2d 901 (1973). A court ordinarily should adjudicate the litigation before it and the plaintiff's choice of a forum should rarely be disturbed unless the balance is strongly in favor of the defendant. A trial of the cause should be permitted in another state only upon a convincing showing that the trial in Wisconsin is likely to result in a substantial injustice. U.I.P. Corp. v. Lawyers Title Insurance Corp. 65 Wis. 2d 377, 222 N.W.2d 638 (1974). A party seeking a stay must show not only that trial in the forum state will be inconvenient and unjust but also that trial in another forum is both more convenient and just. U.I.P. Corp. v. Lawyers Title Insurance Corp. 82 Wis. 2d 616, 264 N.W.2d 525 (1978). Section 801.63 does not control inconvenient forum motions in custody proceedings. Mayer v. Mayer, 91 Wis. 2d 342, 283 N.W.2d 591 (Ct. App. 1979).
