The first attempted service of notice shall be commenced within 28 days of the receipt of the notice from the seizing agency by Form 4-64. If the property seized is a conveyance, notice shall also be directed 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. A complaint for 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 a 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 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 item (ii) of this paragraph (1). 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 shall be accepted as sufficient proof of service by the court.
For purposes of notice under this Section, if a person has been arrested for the conduct giving rise to the forfeiture, 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 complaint for 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.
