Section 404.640 - Jurisdiction for transfers to personal custodianship1. The probate division of the circuit court may hear and determine all matters pertaining to personal custodians and the administration of personal custodianships under sections 404.400 to 404.650.2. The provisions of chapter 472 apply to judicial proceedings involving personal custodianships to the extent they apply to judicial proceedings involving trusts and are not inconsistent with sections 404.400 to 404.650.3. If the probate division of the circuit court appoints a guardian or conservator for a beneficiary of a personal custodianship, after notice and hearing, the court may specify in an order the duties and responsibilities of the beneficiary's legal representatives and personal custodians and the manner in which they shall coordinate the exercise of their respective powers and duties for and on behalf of the beneficiary.4. Upon the filing of any petition as provided in sections 404.400 to 404.650, the court shall issue an order directed to such persons and returnable on such notice as the court may require, to show cause why the relief prayed for in the petition should not be granted and, in due course, shall proceed to grant such relief as the court finds to be in the best interest of the beneficiary of the personal custodianship.
