(a) When operative.--A declaration becomes operative when:

(1) A copy is provided to the attending physician.

(2) The conditions stated in the declaration are met.

(b) Compliance.--When a declaration becomes operative, the attending physician and other mental health care providers shall act in accordance with its provisions or comply with the transfer provisions of section 5804 (relating to compliance).

(c) Invalidity of specific direction.--If a specific direction in the declaration is held to be invalid, the invalidity shall not be construed to negate other directions in the declaration that can be effected without the invalid direction.

(d) Mental health record.--A physician or other mental health care provider to whom a copy of a declaration is furnished shall make it a part of the mental health record of the declarant for at least two years from the date of execution and, if unwilling to comply with the declaration, promptly so advise those listed in section 5804(a)(2).

(e) Duration.--A declaration shall be valid until revoked by the declarant or until two years from the date of execution. If a declaration for mental health treatment has been invoked and is in effect at the specified expiration date after its execution, the declaration shall remain effective until the principal is no longer incapable.

(f) Absence of declaration.--If an individual does not make a declaration, a presumption does not arise regarding the intent of the individual to consent to or to refuse a mental health treatment.
