(1) Venue under this Article lies in the county where the minor resides or is found.(2) If proceedings are commenced in any county other than that of the minor's residence, the court in which the proceedings were initiated may at any time before or after adjudication of wardship transfer the case to the county of the minor's residence by transmitting to the court in that county an authenticated copy of the court record, including all documents, petitions and orders filed therein, and the minute orders and docket entries of the court. Transfer in like manner may be made in the event of a change of residence from one county to another of a minor concerning whom proceedings are pending.
