"Pro Se" denotes voluntarily representing oneself within the court’s jurisdiction, thereby consenting to its authority and procedures. In contrast, "Pro Per" allows individuals to assert their personal status and directly challenge the court’s jurisdiction, avoiding representation as a legal fiction. This distinction underscores the significance of an Affidavit of Power of Attorney In Fact, which empowers an Attorney In Fact to represent a trust without requiring a licensed attorney in the public jurisdiction. Understanding these legal roles is crucial in navigating court standing and asserting constitutional and contractual rights effectively.
