(755 ILCS 45/4-6) (from Ch. 110 1/2, par. 804-6)
    Sec. 4-6. Revocation and amendment of health care agencies.
    (a) Every health care agency may be revoked by the principal at any time, without regard to the principal's mental or physical condition, by any of the following methods:
        1. By being obliterated, burnt, torn or otherwise
    
destroyed or defaced in a manner indicating intention to revoke;
        2. By a written revocation of the agency signed and
    
dated by the principal or person acting at the direction of the principal, regardless of whether the written revocation is in an electronic or hard copy format;
        3. By an oral or any other expression of the intent
    
to revoke the agency in the presence of a witness 18 years of age or older who signs and dates a writing confirming that such expression of intent was made; or
        4. For an electronic health care agency, by deleting
    
in a manner indicating the intention to revoke. An electronic health care agency may be revoked electronically using a generic, technology-neutral system in which each user is assigned a unique identifier that is securely maintained and in a manner that meets the regulatory requirements for a digital or electronic signature. Compliance with the standards defined in the Electronic Commerce Security Act or the implementing rules of the Hospital Licensing Act for medical record entry authentication for author validation of the documentation, content accuracy, and completeness meets this standard.
    (b) Every health care agency may be amended at any time by a written amendment signed and dated by the principal or person acting at the direction of the principal.
    (c) Any person, other than the agent, to whom a revocation or amendment is communicated or delivered shall make all reasonable efforts to inform the agent of that fact as promptly as possible.
