If the amount or validity of a claim cannot be determined until some time in the future, the claim is a contingent claim regardless of whether the claim is based on an event which occurred in the past or on an event which may occur in the future. Except for claims of the type not required to be filed under s. 859.02, contingent claims which cannot be allowed as absolute must, nevertheless, be filed in the court and proved in the same manner as absolute claims. If allowed subject to the contingency, the order of allowance shall state the nature of the contingency. If the claim is allowed as absolute before distribution of the estate, it shall be paid in the same manner as absolute claims of the same class. In all other cases the court may provide for the payment of contingent claims in any one of the following methods:
(1) The creditor and personal representative may determine, by agreement, arbitration or compromise, the value thereof, according to its probable present worth, and it may be allowed and paid in the same manner as an absolute claim.(2) The court may order the personal representative to make distribution of the estate but to retain sufficient funds to pay the claim if and when the same becomes absolute; but for this purpose the estate shall not be kept open longer than 2 years after distribution of the remainder of the estate has been made; and if the claim has not become absolute within that time, distribution shall be made to the distributees of the retained funds, after paying any costs and expenses accruing during such period but the distributees shall be liable to the creditor to the extent provided in s. 859.23, if the contingent claim thereafter becomes absolute. When distribution is so made to distributees, the court may require the distributees to give bond for the satisfaction of their liability to the contingent creditor.(3) The court may order distribution of the estate as though the contingent claim did not exist, but the distributees shall be liable to the creditor as limited by s. 859.23, if the contingent claim thereafter becomes absolute; and the court may require the distributees to give bond for the satisfaction of their liability to the contingent creditor.(4) Such other method as the court orders.
