The person who starts a case by filing the initial petition is the petitioner. This role is all about initiating the action and presenting the request to the court through a petition, which sets the scope of the issues and the relief sought. The respondent is the party who must answer or respond to that petition, a third party would be someone brought into the case who wasn’t the initiator, and a conservator is a court-appointed guardian for someone lacking capacity—not the initiator of a petition. So the term that best describes the initiator of the first petition is petitioner. In some contexts you might see plaintiff instead, but with a petition-based case, petitioner is the precise fit.
