(FRCP) that govern civil litigation in United States courts provide that a civil action is commenced with the filing or service of a pleading called a complaint. Civil court rules in states that have incorporated the Federal Rules of Civil Procedure use the same term for the same pleading.
In Civil Law, a “complaint” is the first formal action taken to officially begin a lawsuit. This written document contains the allegations against the defense, the specific laws violated, the facts that led to the dispute, and any demands made by the plaintiff to restore justice.
In some jurisdictions, specific types of criminal cases may also be commenced by the filing of a complaint, also sometimes called a criminal complaint or felony complaint. Most criminal cases are prosecuted in the name of the governmental authority that promulgates criminal statutes and enforces the
police power of the state with the goal of seeking criminal
sanctions
A sanction may be either a permission or a restriction, depending upon context, as the word is an auto-antonym.
Examples of sanctions include:

Attorney fees
Before filing the complaint, it is important for plaintiff(s) to remember that Federal courts can impose liability for the prevailing party's attorney fees to the losing party, if the judge considers the case
frivolous or for purposes of harassment, even when the case was voluntarily dismissed.
In the case of ''Fox v. Vice'', the U.S. Supreme Court held that reasonable attorneys' fees could be awarded to the defendant under 42 U.S.C. Sec. 1988, but only for costs that the defendant would not have incurred "but for the frivolous claims."
Even when there is no actual trial or judgment, if there is only pre-trial motion practice such as motions to dismiss, attorney fee shifting still can be awarded under
FRCP Rule 11 when the opposing party files a Motion for Sanctions and the court issue an order identifying the sanctioned conduct and the basis for the sanction. The losing party has a right to appeal any order for sanctions in the higher court.
In the state courts, each party is generally responsible only for its own attorney fees, with certain exceptions.
