Wishes in writing with regard to custodianship, enduring power of attorney

A person who is in possession of a document in which a person, for the contingency of their being under custodianship, has communicated suggestions on the choice of the custodian or wishes for the conduct of the custodianship, is to deliver it to the custodianship court without undue delay after they obtain knowledge that proceedings for the appointment of a custodian have been commenced. Similarly, the possessor is to inform the custodianship court of documents in which the person concerned has authorised another person to take care of their affairs. The custodianship court may require a copy to be submitted.
