Civil trial courts serve several purposes, including offering remedies, dispute resolution, and behavior modification. There are various types of civil cases, such as contract cases, personal injury/tort cases, and domestic relations cases. Civil trials involve judges, lawyers, parties, and have defined procedures including pleading, discovery, pre-trial motions, trial, and potential appeal. Parties may also pursue alternative dispute resolution methods outside of trial, such as negotiation, mediation, arbitration, or use of private courts. Class action lawsuits allow for joined claims from a class of similarly situated people who have suffered the same harm.
