There are two types of trial lawyers in a criminal lawsuit. The first one is called a defense attorney. They are the ones who are capable of representing and fighting on behalf of the person being accused or charged. The other one is known as the prosecution. They are the one who fight and represent the law making body of a certain country. Both these trial attorneys use the information they gathered (evidences and statements) and the law of a certain country to prove their client's innocence. However, the final decision will still be made by the judge or a jury. A jury is a group of independent civilians who are chosen to give the verdict.
In a civil trial, both parties can discuss their disputes and come up with an agreement without having broken any law. In this type of trial, civil attorneys are being hired to represent their client from a broad area of the civil law. It could be cases regarding divorce, torts, and business disputes. Each party hires a trial attorney to fight for their outlook. On the other hand, in a constitutional lawsuit, attorneys fight with the government regarding the laws they have made including constitutional changes and Supreme Court rulings. These type of cases require a greater resource to be utilized and tends to require a much longer time frame. Every attorney can decide what specialization he/she may take after passing the barrister exams. They can also work either for a private institution or for the government.
