(765 ILCS 5/31.5)
    Sec. 31.5. Assignment of rents; perfection.
    (a) In this Section:
    "Assigning" includes granting, pledging, transferring, conveying, or assigning an interest in rents.
    "Assignment" includes grants, pledges, transfers, conveyances, or assignments of an interest in rents.
    "Assignor" or "assignee" includes, respectively: (i) grantor or grantee; (ii) pledgor or pledgee; (iii) transferor or transferee; (iv) conveyor or conveyee; (v) lender or borrower; and (vi) assignor or assignee. "Assignor" also means a lessor or sublessor.
    "Instrument" includes any written deed, grant, mortgage, deed or trust, lease, assignment, release, or any other writing pertaining to land or real property or any interest therein or appurtenant thereto, including an interest in rents.
    "Rents" means all items that constitute leases, rents, and profits arising from real property under applicable State law.
    (b) If an instrument assigning the interest of the assignor in rents arising from the real property described in the instrument is recorded, pursuant to this Act, in the county in which the real property is situated, then the interest of the assignee in those rents is perfected upon that recordation without the assignee taking any other affirmative action.
    The recordation is constructive notice to subsequent purchasers, creditors, and third parties of the content and effect of the assignment with the same force and effect as any other duly recorded instrument or conveyance of an interest in real property under Sections 30 and 31 of this Act. From the time of the recordation, the assignee has a superior claim to the rents that are subjected to the assignment, as against all parties whose claims or interests arise or are perfected thereafter.
    (c) This Section applies whether the assignment is absolute, conditional, or intended as security.
    (d) Unless otherwise agreed to by the parties, the mere recordation of an assignment does not affect who is entitled, as between the assignor and the assignee, to collect or receive rents until the assignee enforces the assignment under applicable law.
    (e) The fact that the assignee may permit the assignor to collect rents under the terms of an assignment does not affect the validity, enforceability, or priority of an assignment perfected in the manner set forth in subsection (b).
