There are a few reasons why lawyers use ESQ after their names. First, it is a way to indicate that they are members of the legal profession. Second, it can be a way to show respect for the law and the legal system. Third, it can be a way to distinguish themselves from other professionals who may have similar job titles.
ESQ is not a protected title, so anyone can use it. However, it is important to note that using ESQ without being a lawyer can be misleading. In some jurisdictions, it may even be considered a form of false advertising.
If you are not a lawyer, you should not use ESQ after your name. If you are a lawyer, you may use ESQ after your name, but you should be aware of the potential consequences of doing so.
