Missouri Revised Statutes Title XIX. Motor Vehicles, Watercraft and Aviation § 301.644. Electronic signature permitted, when

1. In cases where an insurance company has paid or is paying a total loss claim on a motor vehicle or trailer, the registered owner or owners of a motor vehicle or trailer may use an electronic signature in a similar form as that prescribed in sections 432.200 to 432.295 on a limited power of attorney, affidavit, or other documents to authorize the insurance company to assign ownership of such motor vehicle or trailer. A power of attorney, affidavit, or other similar document executed with an electronic signature for the authority to execute the assignment of a certificate of ownership by an insurance company under the authority of this section shall not require notarization.

2. The director of the department of revenue may promulgate rules and regulations to implement and administer the provisions of this section. Any rule or portion of a rule, as that term is defined in section 536.010, that is created under the authority delegated in this section shall become effective only if it complies with and is subject to all of the provisions of chapter 536 and, if applicable, section 536.028. This section and chapter 536 are nonseverable and if any of the powers vested with the general assembly under chapter 536 to review, to delay the effective date, or to disapprove and annul a rule are subsequently held unconstitutional, then the grant of rulemaking authority and any rule proposed or adopted after August 28, 2015, shall be invalid and void.
