How New York Law Affects Your Professional Malpractice Case
Damages equal the financial loss the professional's error actually caused — what you lost or failed to gain because of it. In legal malpractice, New York typically requires proving the "case within a case": that you would have won the underlying matter but for the attorney's error. Engagement letters, billing records, and the professional's own file are critical evidence.
New York generally allows about 2.5 years to file, in line with the national average of 2.3 years, often running from when you discovered (or should have discovered) the error. For attorney malpractice, the "continuous representation" rule can pause the clock while the lawyer keeps handling the matter.
