In the Matter of Sage Realty Corporation, Appellants v. Proskauer Rose Goetz & Mendelsohn LLP, Respondent

Summary

The New York Court of Appeals reversed the Appellate Division and held that former clients are entitled to inspect and copy the entire attorney's file, including work‑product materials, unless the attorney demonstrates a substantial reason to withhold them, such as third‑party confidentiality or internal law‑office use. The court also affirmed that attorneys may charge reasonable fees for producing undisclosed documents.
