Mail shall be sent at least 7 days before the hearing, except as follows: 1.

When a petition under s. 938.13(4), (6), (6m), or (7) involves an Indian juvenile who has been removed from the home of his or her parent or Indian custodian and the person to be notified is the Indian juvenile's parent, Indian custodian, or tribe, the mail shall be sent so that it is received by the person to be notified at least 10 days before the hearing or, if the identity or location of the person to be notified cannot be determined by the U.S. secretary of the interior at least 15 days before the hearing.(2) BY WHOM MADE.

The expenses of service of summons or notice or of the publication of summons or notice and the traveling expenses and fees as allowed in ch. 885 incurred by any person summoned or required to appear at the hearing of any case coming within the jurisdiction of the court under s. 938.12 , 938.125 , 938.13 or 938.14 shall be a charge on the county when approved by the court.1995 a. 77; 1997 a. 35, 181; 1999 a. 32; 2005 a. 344; 2009 a. 94. Failure to follow the statutory requirements for service defeated the state's assertion of personal jurisdiction and required the juvenile court to vacate its waiver order and the circuit court to dismiss criminal charges without prejudice. Personal jurisdiction depends on compliance with the procedures in sub. (1). The state's assertion that proper documents had been mailed to various addresses and not returned and that the juvenile had actual notice did not establish personal jurisdiction, nor does personal jurisdiction attach when a delinquency petition is filed.
