The lawyer is the professional responsible for defending the interests of a natural or legal person, in view of the legal issues of the country in which he / she operates. In order to make this defense, the lawyer needs to have a good knowledge of the laws, develop convincing arguments and communicate verbally in an appropriate manner. In the most common cases, the lawyer receives the client in his office, studies the case and the possibilities of defense or prosecution and offers the most advantageous solutions that the law allows. For providing his services, the professional receives his fees, which are previously agreed between the parties. In addition to the day-to-day life of the courts, the lawyer can also consult on laws for people and companies that need to base their actions and avoid legal conflicts.
