Final Answer:
Those dealing under a duty executed power of attorney are individuals who have the legal authority to act on behalf of another person, known as the principal, based on a power of attorney document that has already been signed and executed.
Step-by-step explanation:
A duty executed power of attorney is a legal instrument that grants someone the authority to make decisions and take actions on behalf of another individual. In this context, "those dealing" refers to the individuals or agents who hold this legal power. The term "duty executed" implies that the power of attorney has already been created and is in effect.
When a person executes a power of attorney, they designate an agent or attorney-in-fact to handle specific matters on their behalf. This could include financial transactions, healthcare decisions, or other legal actions. The individuals dealing under this power of attorney are obligated to act in the best interest of the principal and within the scope of the authority granted by the power of attorney document.
The use of a power of attorney is a legal mechanism that facilitates decision-making in situations where the principal may be unable or unwilling to make decisions themselves. It is essential for those acting under a power of attorney to understand their responsibilities and exercise their authority ethically and within the legal framework outlined in the document.
