(765 ILCS 1026/15-301)
    Sec. 15-301. Address of apparent owner to establish priority. In this Article, the following rules apply:
        (1) The last-known address of an apparent owner is
    
any description, code, or other indication of the location of the apparent owner which identifies the state, even if the description, code, or indication of location is not sufficient to direct the delivery of first-class United States mail to the apparent owner.
        (2) If the United States postal zip code associated
    
with the apparent owner is for a post office located in this State, this State is deemed to be the state of the last-known address of the apparent owner unless other records associated with the apparent owner specifically identify the physical address of the apparent owner to be in another state.
        (3) If the address under paragraph (2) is in another
    
state, the other state is deemed to be the state of the last-known address of the apparent owner.
        (4) The address of the apparent owner of a life or
    
endowment insurance policy or annuity contract or its proceeds is presumed to be the address of the insured or annuitant if a person other than the insured or annuitant is entitled to the amount owed under the policy or contract and the address of the other person is not known by the insurance company and cannot be determined under Section 15-302. The address of the apparent owner of other property where ownership vests in a beneficiary upon the death of the owner is presumed to be the address of the now-deceased owner if the address of the beneficiary is not known by the holder and cannot be determined under Section 15-302.
