Section 404.735 - Repeal of sections 486.550 to 486.595 does not affect validity of existing durable powers of attorney1. The repeal of the Missouri durable power of attorney law, sections 486.550 to 486.595, shall not affect the validity of durable powers of attorney created under that law, the validity of the acts and transactions of attorneys in fact under authority granted in durable powers of attorney executed under that law, or the duties of attorneys in fact under durable powers of attorney executed under that law.2. The provisions of sections 404.700 and 404.703, subsections 2, 3 and 4 of section 404.705, and sections 404.707 to 404.735 henceforth apply to durable powers of attorney executed before August 28, 1989, insofar as the application of sections 404.700 to 404.735 does not impair constitutionally vested rights.3. A power of attorney that complies with the provisions of subsection 1 of section 404.705 and that was executed before August 28, 1989, is durable and valid after August 28, 1989.4. A durable power of attorney executed under prior law need not be recorded as provided in that law to be effective and durable except as to conveyances of real estate; and the appointment of a legal representative for the principal or the principal's estate shall not require an accounting by an attorney in fact acting under a power of attorney executed under prior law, unless ordered by a court pursuant to a petition to the court under section 404.727.5. Compliance with the provisions of subsection 1 of section 404.705 is not required for durability of a power of attorney executed prior to January 1, 1990, if the form of the power of attorney was sufficient for durability under subdivision (2) of section 486.555, RSMo 1986.
