Subject matter and personal jurisdiction.
(a) The circuit courts of this State shall have jurisdiction of an action brought under this Act. In a civil action not brought under this Act, the provisions of this Act shall apply if parentage is at issue. The court may join any action under this Act with any other civil action in which this Act is applicable.
(b) An individual may not be adjudicated to be a parent unless the court has personal jurisdiction over the individual.
(c) A court of this State having jurisdiction to adjudicate parentage may exercise personal jurisdiction over a nonresident individual, or the guardian or conservator of the individual, if the conditions prescribed in Section 201 of the Uniform Interstate Family Support Act are fulfilled.
(d) Lack of jurisdiction over one individual does not preclude the court from making an adjudication of parentage binding on another individual over whom the court has personal jurisdiction.
