Article 4 - Creation, validity, modification, and termination of trust
§ 91-8-401. Methods of creating trust

A trust may be created by:
Expressly grants authority to create the trust; or
Grants the agent or attorney-in-fact the authority to act in the management and disposition of the principal's property that is as broad or comprehensive as the principal could exercise for himself or herself and that does not expressly exclude the authority to create a trust. An agent or attorney-in-fact may file a petition for the court to determine whether a power of attorney described in this section grants the agent or attorney-in-fact authority that is as broad or comprehensive as that which the principal could exercise for himself or herself.
