A more thorough explanation:

Definition: Exequatur is a written authorization and recognition given by a government to a consular officer who is accredited to that government. The term comes from the Latin phrase "let it be executed."

For example, when a consular officer is appointed by their home country to work in another country, they must present proof of their appointment to the government of the country where they will be working. If the government approves of the appointment and finds the officer to be suitable, they will issue an exequatur, which allows the officer to perform their duties within the limits set by the government.

The exequatur can be withdrawn if the officer engages in any misconduct or violates the terms of their appointment.

Overall, an exequatur is an important document that allows consular officers to carry out their duties in a foreign country with the approval and recognition of the host government.
