A
lawyer is an
independent professional, BA in Law and licensed by the competent institutions of each country to practice jus postulandi, i.e.,
to represent the interests of the physical or legal entities in court or outside court, both between the entities and the State.The lawyer is an
essential piece for justice administration and a basic instrument to ensure the defense of the interests of the parts in court.
Thus, advocacy not only is a profession, but a munus publicum, i.e., a public obligation, because, even though it is not a state agent, it is part of the democracy administration of the Judicial Power.
