The first document filed with the court (actually with the county clerk or clerk of the court) by a person or entity claiming legal rights against another. the party filing the complaint is usually called the plaintiff and the party against whom the complaint is filed is called the defendant or defendants. complaints are pleadings and must be drafted carefully (usually by an attorney) to properly state the factual as well as legal basis for the claim, although some states have approved complaint forms which can be filled in by an individual. a complaint also must follow statutory requirements as to form. for example, a complaint must be typed on a specific type of paper or on forms approved by the courts, name both the party making the claim and all defendants, and should state what damages or performance is demanded (the prayer). when the complaint is filed, the court clerk will issue a summons, which gives the name and file number of the lawsuit and the address of the attorney filing the complaint, and instructs the defendant that he/she/it has a specific time to file an answer or other response. a copy of the complaint and the summons must be served on a defendant before a response is required. under a unique statute, new york allows a summons to be served without a complaint. a complaint filing must be accompanied by a filing fee payable to the court clerk, unless a waiver based on poverty is obtained.
