(9) A document modifying, amending, correcting, or revoking any written estate planning document.

2. (1) An electronic estate planning document or an electronic signature on such document shall be attributable to a person if it was the act of the person. The act of the person may be shown in any manner, including a showing of the efficacy of a security procedure applied to determine the person to which the electronic record or signature was attributable.

(2) The effect of attribution of a document or signature to a person pursuant to subdivision (1) of this subsection shall be determined from the context and surrounding circumstances at the time of its creation, execution, or adoption and as provided by other provisions of law.

If a provision of law or rule of procedure requires an estate planning document to be presented or retained in its original form or provides legal consequences for the information not being presented or retained in its original form, such provision or rule shall be satisfied by a certified paper copy of an electronic document.

4. Any written estate planning document, other than a will, that requires one or more witnesses to the signature of a principal may be witnessed by any individual or individuals in the electronic presence of the principal.

5. A person who acts in reliance upon an electronically executed written estate planning document shall not be liable to any person for so relying and may assume without inquiry the valid execution of the electronically executed written estate planning document.

6. This section does not require a written estate planning document to be electronically signed.
