A plaintiff is the party who initiates a lawsuit before a court. By doing so, the plaintiff seeks a legal remedy; if this search is successful, the court will issue judgment in favor of the plaintiff and make the appropriate court order. "Plaintiff" is the term used in civil cases in most English-speaking jurisdictions, the notable exception being England and Wales, where a plaintiff has, since the introduction of the Civil Procedure Rulesin 1999, been known as a "claimant", but that term also has other meanings. In criminal cases, the prosecutor brings the case against the defendant, but the key complaining party is often called the "complainant". In some jurisdictions, a lawsuit is commenced by filing a summons, claim form or a complaint. These documents are known as pleadings, that set forth the alleged wrongs committed by the defendant or defendants with a demand for relief. In other jurisdictions, the action is commenced by service of legal process by delivery of these documents on the defendant by a process server; they are only filed with the court subsequently with an affidavit from the process server that they had been given to the defendant according to the rules of civil procedure.
Terminology
In most English-speaking jurisdictions, including Hong Kong, Nigeria, Australia, Canada and the United States, as well as in both Northern Ireland and the Republic of Ireland, the legal term "plaintiff" is used as a general term for the party taking action in a civil case. The word plaintiff can be traced to the year 1278, and stems from the Anglo-French word pleintif meaning "complaining". It was identical to "" at first and receded into legal usage with the -iff spelling in the 15th century. A plaintiff identified by name in a class action is called a named plaintiff. In most common-law jurisdictions, the term "claimant" used in England and Wales since 1999 is used only in specific, often non-judicial contexts. In particular, in American usage, terms such as "claimant" and "claim form" are limited to extrajudicial process in insurance and administrative law. After exhausting remedies available through an insurer or government agency, an American claimant in need of further relief would turn to the courts, file a complaint and become a plaintiff. In England and Wales, the term "claimant" replaced "plaintiff" after the Civil Procedure Rules came into force on 26 April 1999. The move, which brings England and Wales out of line with general usage in English-speaking jurisdictions, was reportedly based on an assessment that the word "claimant" is more acceptable as "plain English" than the word "plaintiff". In Scottish law a plaintiff is referred to as a "pursuer" and a defendant as a "defender". The party against whom the complaint is made is the defendant; or, in the case of a petition, a respondent. Case names are usually given with the plaintiff first, as in Plaintiff v. Defendant. The similar term "complainant" denotes the complaining witness in a criminal proceeding.
