Anyone assigning power of attorney should take care to choose someone they trust.
If the attorney-in-fact is designated as a general power of attorney, they are allowed to conduct any actions that the principal would reasonably take. This means an attorney-in-fact would be able to open and close bank accounts, withdraw funds, trade stocks, pay bills, and cash checks—all on behalf of the principal.
With a limited power of attorney, the attorney-in-fact is granted broad powers in one or more areas but not others. For example, the attorney-in-fact could be authorized to carry out transactions at the direction of the principal but not to make business or financial decisions. It could also be narrower, such as only granting the right to sign documents related to the pending sale of a specific piece of property.
As noted above, an attorney-in-fact need not be a lawyer. And another term for “lawyer” is “attorney-at-law.” If you have passed a state bar exam and are thus legally qualified in that state to prosecute and defend actions in a court on behalf of a client who has retained you, then you are an attorney-at-law.56
Their functions are also different. An attorney-in-fact must make decisions for their principal, while an attorney-at-law makes no decisions for their client. Instead, they offer advice to their client and can represent them in the courtroom.1
