The first attempted service of notice shall be commenced within 28 days of the filing of the verified claim or the receipt of the notice from the seizing agency by Illinois State Police Notice/Inventory of Seized Property (Form 4-64), whichever occurs sooner. A complaint for forfeiture or a notice of pending forfeiture shall be served upon the property owner or interest holder in the following manner:
The attempts at service and the posting, if required, shall be documented by the person attempting service and said documentation shall be made part of a return of service returned to the State's Attorney.
The State's Attorney may utilize any Sheriff or Deputy Sheriff, any peace officer, a private process server or investigator, or any employee, agent, or investigator of the State's Attorney's Office to attempt service without seeking leave of court.
After the procedures set forth are followed, service shall be effective on an owner or interest holder on the date of receipt by the State's Attorney of a return receipt, or on the date of receipt of a communication from an owner or interest holder documenting actual notice, whichever is first in time, or on the date of the last act performed by the State's Attorney in attempting personal service under subparagraph (ii) above. If notice is to be shown by actual notice from communication with a claimant, then the State's Attorney shall file an affidavit providing details of the communication, which may be accepted as sufficient proof of service by the court.
After a claimant files a verified claim with the State's Attorney and provides an address at which the claimant will accept service, the complaint shall be served and notice shall be perfected upon mailing of the complaint to the claimant at the address the claimant provided via certified mail, return receipt requested, and first class mail. No return receipt need be received, or any other attempts at service need be made to comply with service and notice requirements under this Act. This certified mailing, return receipt requested, shall be proof of service of the complaint on the claimant.
For purposes of notice under this Section, if a person has been arrested for the conduct giving rise to the forfeiture, then the address provided to the arresting agency at the time of arrest shall be deemed to be that person's known address. Provided, however, if an owner or interest holder's address changes prior to the effective date of the notice of pending forfeiture, the owner or interest holder shall promptly notify the seizing agency of the change in address or, if the owner or interest holder's address changes subsequent to the effective date of the notice of pending forfeiture, the owner or interest holder shall promptly notify the State's Attorney of the change in address; or if the property seized is a conveyance, to the address reflected in the office of the agency or official in which title to or interest in the conveyance is required by law to be recorded.
