What document initiates a lawsuit regarding a liability insurance claim?

The document that initiates a lawsuit regarding a liability insurance claim is known as a complaint. This formal legal document outlines the plaintiff's allegations against the defendant, stating the basis for the lawsuit and the relief sought. A complaint serves to inform the court and the defendant of the specifics of the claims, including relevant facts and the legal grounds upon which the case is founded.

While a summons is issued to inform the defendant that a lawsuit has been filed against them, it does not itself contain the details of the claim. A motion generally requests a court order or ruling on a specific issue within a case but does not start a lawsuit. A statement of claim may be used in certain jurisdictions or contexts, but it is not typically the primary document used to initiate litigation in the context of a liability insurance claim in Connecticut. Thus, the complaint is the correct document for formally starting the process of a lawsuit.
