Yes, someone with a power of attorney can delegate or substitute authority to another individual.
Step-by-step explanation:
Yes, someone with a power of attorney can delegate or substitute authority to another individual. A power of attorney is a legal document that grants someone the authority to make decisions on behalf of another person, known as the principal. The person granted this authority, known as the agent or attorney-in-fact, can delegate their powers to another person if the power of attorney document permits it. For example, if an individual is unable to attend a meeting, they may delegate their authority to another person to represent them and make decisions on their behalf.
