735 ILCS 5/2-402
The plaintiff in any civil action may designate as respondents in discovery in his or her pleading those individuals or other entities, other than the named defendants, believed by the plaintiff to have information essential to the determination of who should properly be named as additional defendants in the action.
Persons or entities so named as respondents in discovery shall be required to respond to discovery by the plaintiff in the same manner as are defendants and may, on motion of the plaintiff, be added as defendants if the evidence discloses the existence of probable cause for such action.
A person or entity named a respondent in discovery may upon his or her own motion be made a defendant in the action, in which case the provisions of this Section are no longer applicable to that person.
A copy of the complaint shall be served on each person or entity named as a respondent in discovery.
Each respondent in discovery shall be paid expenses and fees as provided for witnesses.
A person or entity named as a respondent in discovery in any civil action may be made a defendant in the same action at any time within 6 months after being named as a respondent in discovery, even though the time during which an action may otherwise be initiated against him or her may have expired during such 6 month period. An extension from the original 6-month period for good cause may be granted only once for up to 90 days for (i) withdrawal of plaintiff's counsel or (ii) good cause. Notwithstanding the limitations in this Section, the court may grant additional reasonable extensions from this 6-month period for a failure or refusal on the part of the respondent to comply with timely filed discovery.
The plaintiff shall serve upon the respondent or respondents a copy of the complaint together with a summons in a form substantially as follows:
