(705 ILCS 405/3-17) (from Ch. 37, par. 803-17)
    Sec. 3-17. Summons. (1) When a petition is filed, the clerk of the court shall issue a summons with a copy of the petition attached. The summons shall be directed to the minor's legal guardian or custodian and to each person named as a respondent in the petition, except that summons need not be directed to a minor respondent under 8 years of age for whom the court appoints a guardian ad litem if the guardian ad litem appears on behalf of the minor in any proceeding under this Act.
    (2) The summons must contain a statement that the minor or any of the respondents is entitled to have an attorney present at the hearing on the petition, and that the clerk of the court should be notified promptly if the minor or any other respondent desires to be represented by an attorney but is financially unable to employ counsel.
    (3) The summons shall be issued under the seal of the court, attested to and signed with the name of the clerk of the court, dated on the day it is issued, and shall require each respondent to appear and answer the petition on the date set for the adjudicatory hearing.
    (4) The summons may be served by any county sheriff, coroner or probation officer, even though the officer is the petitioner. The return of the summons with endorsement of service by the officer is sufficient proof thereof.
    (5) Service of a summons and petition shall be made by: (a) leaving a copy thereof with the person summoned at least 3 days before the time stated therein for appearance; (b) leaving a copy at his usual place of abode with some person of the family, of the age of 10 years or upwards, and informing that person of the contents thereof, provided the officer or other person making service shall also send a copy of the summons in a sealed envelope with postage fully prepaid, addressed to the person summoned at his usual place of abode, at least 3 days before the time stated therein for appearance; or (c) leaving a copy thereof with the guardian or custodian of a minor, at least 3 days before the time stated therein for appearance. If the guardian or custodian is an agency of the State of Illinois, proper service may be made by leaving a copy of the summons and petition with any administrative employee of such agency designated by such agency to accept service of summons and petitions. The certificate of the officer or affidavit of the person that he has sent the copy pursuant to this Section is sufficient proof of service.
    (6) When a parent or other person, who has signed a written promise to appear and bring the minor to court or who has waived or acknowledged service, fails to appear with the minor on the date set by the court, a bench warrant may be issued for the parent or other person, the minor, or both.
    (7) The appearance of the minor's legal guardian or custodian, or a person named as a respondent in a petition, in any proceeding under this Act shall constitute a waiver of service of summons and submission to the jurisdiction of the court. A copy of the summons and petition shall be provided to the person at the time of his appearance.
