The Advocate-on-Record (AOR) constitutes the procedural backbone of the Supreme Court of India. Governed by Order IV of the Supreme Court Rules, 2013, an AOR is an advocate who has cleared a rigorous examination conducted by the Supreme Court, completed mandatory training under an existing senior AOR, and maintains a registered office within a 16-kilometer radius of the Supreme Court building in New Delhi.
The AOR designation remains one of the most exclusive credentials in the Indian legal profession. Supreme Court Registry records show that only around 3,700-odd advocates hold a live AOR registration nationwide, a fraction of India’s roughly 20-lakh-strong Bar. The examination itself is notoriously difficult, with a historical pass rate of approximately 20%; in the AOR Examination, for instance, only few candidates clear the test out of the pool that appeared. This scarcity is precisely why an experienced, well-briefed Advocate-on-Record is indispensable to any Apex Court strategy.
Under the law, an AOR holds the exclusive statutory entitlement to act, file petitions, submit vakalatnamas, and plead on behalf of a litigant in the Supreme Court. No matter—whether a Special Leave Petition (SLP), Writ Petition, or Transfer Petition—can be formally instituted or processed by the Supreme Court Registry without the signature and endorsement of an Advocate-on-Record.
The AOR remains professionally accountable to the Court for the accuracy of the pleadings, the proper deposit of court fees, and the overall conduct of the case. While an AOR can argue cases independently before any Bench, they also serve as the briefing counsel who instructs designated Senior Advocates.
