What the claim has to show
Legal malpractice is a negligence claim against a lawyer, and it asks two hard questions. The first is whether the lawyer failed to use the skill and care that lawyers ordinarily exercise. The second is whether that failure actually caused a loss. In New York, the second question usually means showing that, but for the lawyer's error, you would have obtained a better result in the underlying matter or avoided the loss. This is often described as proving a case within a case, and it can make a malpractice claim as complex as the original matter. Strategic choices that turned out badly are generally not malpractice if they were reasonable when made.
Routes that are not malpractice
Not every complaint about a lawyer belongs in a malpractice case. Disputes over fees in New York can often go through a court-run fee dispute resolution program. Ethical violations, such as mishandling client money or acting under a conflict of interest, can be reported to the attorney grievance committee for the relevant judicial department, which handles discipline but does not award damages. Some situations involve more than one of these paths. Knowing which one fits keeps you from spending months on a process that cannot give you what you need.
Getting the file and acting in time
Clients are generally entitled to their file, and requesting it in writing is usually the first step. Bring engagement letters, invoices, correspondence, court papers, and any notices about deadlines. Malpractice claims have time limits, and in New York the period may be extended while the lawyer continues representing you on the same matter, but that rule is narrow and should not be relied on without advice. If the underlying matter is still open, deadlines in that case may need attention immediately. We review what happened, what it cost you, and whether the underlying matter could realistically have come out differently.
