(735 ILCS 5/13-121) (from Ch. 110, par. 13-121)
    Sec. 13-121. Construction. Sections 13-118 through 13-121 of this Act shall be liberally construed to effect the legislative purpose of simplifying and facilitating land title transactions by allowing persons to rely on a record chain of title as described in Section 13-118 of this Act, subject to such limitations as appear in Section 13-120 of this Act. The claims extinguished by Sections 13-118 through 13-121 of this Act include any and all interests of any nature whatsoever, however denominated, whether vested or contingent, whether present or future, whether such claims are asserted by a person sui juris or under disability or might be asserted by a person not yet in being, whether such person be within or without the State, and whether such person be natural or corporate, or private or governmental.
    Except as otherwise provided in Sections 13-118 through 13-121 of this Act, the rule that the State of Illinois is not bound by acts of limitations shall not apply to Sections 13-118 through 13-121 of this Act, and these Sections shall serve to bar any right, title, interest or lien in land which the State of Illinois or any department, commission or political subdivision thereof would otherwise have.
