State context & due diligence
For benchmarking context, New York has 429,620 registered attorneys statewide, of which 284,296 (66.2%) are actively registered — this attorney's "Suspended, delinquent" status places them outside the active cohort. Bar registration status alone does not confirm competence, specialty, or fit for a specific legal matter — it confirms only that the attorney has met the bar's registration requirements as of the last reporting cycle. Before engaging any attorney, verify their current standing directly with the state bar, review any discipline history through official channels, confirm fee structure in writing, and ask about specific experience handling matters similar to yours. Public profiles like this one are a starting point for due diligence, not a substitute for it.
