New York Judiciary Law §470 states that any person admitted to practice law in this state who is not a resident of New York may not practice law in New York unless they maintain 'an office for the transaction of law business within the state.' The New York Court of Appeals has interpreted this requirement to mean a genuine, physical law office — not a virtual mailbox, not a coworking membership, not a shared desk arrangement. Our investigation of Ernestas Pravilionis and EPRA Legal found that all three of the firm's listed New York office addresses appear to be virtual services, not physical law offices. This topic covers §470's history, the case law interpreting it, the practical consequences of violation, and what the New York grievance committees have said about the requirement.
