The NYLJ 100 ranks the 100 largest firms by number of lawyers in the state of New York. Every private law office in the state is considered, irrespective of where the firm is headquartered or where it claims a home office. Non-U.S.-based law firms are considered equally with domestic U.S. firms; the sole criterion for inclusion in the NYLJ 100 is the size of a firm’s New York state presence.

Law offices are ranked by the total number of permanent, full-time-equivalent attorneys (partners plus associates plus “other attorneys”—staff attorneys, of counsel, etc.); where a firm has more than one office in New York state, the attorney totals for each office are added together to arrive at one statewide total. In the case of a tie between or among firms, they are ranked equally but listed alphabetically.
