The laws and judicial regulations applicable in the Sultanate of Oman elucidate the provisions of the principal's liability for the acts committed by their agents. The principal becomes accountable for the actions undertaken by others not under their direct guidance and supervision during the occurrence of the harmful act. The extent of vicarious liability is determined based on the actual authority wielded by the principal towards their agents, even in cases of plurality. Research findings clarify that both Omani Civil Transactions Law and the Omani judiciary have established the liability of the principal based on presumed fault and warranty. The right of the necessitated party to seek recourse from both sides of the agency relationship is affirmed. Research recommendations focus on amending the text of Article (196/1) of the Civil Transactions Law, adding a provision allowing the principal to indemnify themselves and recognizing the modern theory that integrates both the theory of presumed fault and the theory of warranty. The research topic is divided into two chapters: the first, titled "The Nature of the Agency Relationship and the Resulting Liability," and the second, titled "The Liability of the Principal for the Acts of Their Agents in Omani Law and Judiciary," extending from each chapter into two subtopics. Keywords: Responsibility, The Subordinate by, Act Committed by, Omani Law and Judiciary
