(2) have been served upon the defendant as follows:(a) If the defendant is known, defendant may be served in the manner prescribed for service of a summons in s. 801.11 , but service in such a case shall not bind the defendant personally to the jurisdiction of the court unless some ground for the exercise of personal jurisdiction exists.(b) If the defendant is unknown the summons may be served by publication thereof as a class 3 notice, under ch. 985.(2) The notice of object of action shall be subscribed by the plaintiff or attorney and shall state the general object of the action, a brief description of all the property affected by it, if it affects specific real or personal property, the fact that no personal claim is made against such defendant, and that a copy of the complaint will be delivered personally or by mail to such defendant upon request made within the time fixed in s. 801.09(2) . If a defendant upon whom such notice is served unreasonably defends the action the defendant shall pay costs to the plaintiff.Sup. Ct. Order, 67 Wis. 2d 585, 606 (1975); 1975 c. 218. Personal jurisdiction in fact, in addition to statutorily acceptable service, is a condition precedent to the exercise of jurisdiction in rem or quasi in rem upon a status or upon a property.
