Litigation firms are essentially law firms that try litigation cases in a court of law on behalf of a plaintiff or defendant. Litigation refers to the legal process of bringing a lawsuit or case to try or contest in a court of law. Parties involved in a litigation case are called litigants while persons trying the case on behalf of the litigants are referred to as trial attorneys or trial lawyers.
There are many services rendered by a litigation firm, most involve actual court trial or lead up to that event. Services such as research with regards to evidence and witness testimonies are provided when necessary by a litigation firm via a firm associate. However, not all court cases handled by litigation firms result in or are resolved by a court trial. Most lawsuits eventually conclude into a settlement between both litigants and their trial attorneys. A court trial may proceed, but litigation may prove to be unnecessary and time-consuming such that a settlement may ultimately be sought and reached between a defendant and a plaintiff. A settlement is understood as a compromise between both parties that result into a resolution that no longer needs a judgment from a judge or jury.
A litigation firm may vary in size depending on the number of partners—junior and senior, paralegals, associates, clerks, and administrative staff it has. Size is does not determine the number of cases a litigation firm decides to take, but is indicative of the amount of resources a litigation firm spends on its cases.
