A more thorough explanation:

An attorney-in-fact is a person who is authorized to act on behalf of another person, but is not necessarily a lawyer. This person is given the authority to act through a legal document called a power of attorney. The attorney-in-fact is a fiduciary, which means they have a legal obligation to act in the best interest of the person they are representing.

John is an elderly man who is no longer able to manage his finances. He gives his daughter, Jane, a power of attorney to act as his attorney-in-fact. Jane is now authorized to manage John's bank accounts, pay his bills, and make financial decisions on his behalf.

Another example could be a person who is traveling out of the country and gives a friend or family member a power of attorney to handle their affairs while they are away. This could include signing contracts, making medical decisions, or managing their property.

These examples illustrate how an attorney-in-fact can be anyone who is trusted by the person they are representing. It is important to choose someone who is responsible and capable of handling the duties assigned to them.
