esq - esquire

When the title "Esq." is used as a suffix in the United States, it is usually used to designate individuals who are licensed to practice law in at least one United States jurisdiction.
This is not as what it is in UK.
It is used less commonly for individuals who have earned law degrees—such as a Juris Doctor (J.D.) or Bachelor of Laws (LL.B.)—but who do not currently practice law or who have never been licensed to practice law, and for students who are still pursuing their law degrees (as they are considered members of the legal profession).
So, if u are living in UK or Europe, this is mot for you .
It may also be used when addressing naval officers in formal correspondence.
Though commonly misunderstood to be the right solely of lawyers, the title "esquire" after the name may actually be used by anyone in many states.
This is only applied in US.
In some states, using the term in a manner that might lead others to assume you are licensed to practice law in that state can be used as evidence of unauthorized practice of law.
It has been used historically, and still is seen occasionally, as merely a more formal honorific than "mister".
