A more thorough explanation:

An attornatus is a legal term that refers to a person who is appointed to take the place of another person. This person is also known as an attorney.

• When a landlord sells a property, the new owner may appoint an attornatus to take over the landlord's responsibilities, such as collecting rent and maintaining the property.
• In a legal case, a person may hire an attornatus to represent them in court and act on their behalf.

These examples illustrate how an attornatus can be appointed to take over the responsibilities or legal representation of another person.
