Louis J. Maione


The Law Offices of Louis J. Maione, P.C., located in New York City, is a boutique law firm specializing in corporate and commercial litigation, products liability matters, discrimination matters and arbitration. Mr. Maione, an experienced New York and New Jersey trial lawyer, started his legal career with a financial services holding company that owned and operated, among other entities, a number of banks, as well as securities clearing and transfer companies, and an insurance company. Over his career he has specialized in matters which involve securities firms and individuals in that industry. Mr. Maione represents both individuals and small to mid-size corporations in arbitrations, trials, and regulatory matters. His business background enables him to counsel business clients in the language they understand.


An experienced, sophisticated commercial litigator with reasonable hourly fees providing hands on services on a personal level. As a result of lean efficiency, ours is a business oriented boutique law firm that meets the financial needs of small businesses and individuals. An attorney and former American Arbitration Association Neutral who not only understands your business, but your business needs as well (See Mission Statement). An attorney who succeeds in arbitrations because as an arbitrator he knows what is expected to make your case; and in litigation because he knows how to settle matters successfully for his clients while avoiding years of protracted litigation but is also an adept trial lawyer who does not shy away from bringing your claim to the jury (See Blog for recent case developments).


The Problem:

Many small to mid-size corporations, as well as individuals, virtually have been closed out of the quality legal service market because ever increasing legal fees have made it impossible in many instances to retain quality representation while achieving the client’s goals. Experts addressing today’s many problems confronting the larger and mid-size law firms, have commented that financial costs have proliferated to the point where many clients, mostly corporations, are determined, if not compelled, to reduce their own costs and get away from the higher priced firms
In addition, in-house counsel is a fixed and ongoing cost and unless the corporation develops a substantial enough staff to meet every legal issue, which then creates but another growing cost center, it will still be forced to retain outside counsel to address those issues for which in-house counsel does not possess the expertise, or the equally important experience to handle the matter effectively.

The Solution:

Experienced, cost conscious, reasonably priced, practitioners like Louis J. Maione, Esq., who, because he is devoting all his time to your matter, provides individuals and smaller corporations with alternatives to skyrocketing legal costs by providing the attention your matter deserves, with reasonable rates that allow you to receive the quality service you deserve. A practitioner with more than 46 years of experience as a litigator in New York and New Jersey, and as counsel to many businesses, believes that the practice of law should remain the noble profession that it was intended to be, rather than merely becoming no more than another big business.

In addition to his law degree, Mr. Maione holds an M.B.A. in Finance; he generally represents and counsels small to mid-size corporations, as well as individuals. In doing so, Mr. Maione, who in his professional practice has been a partner in two New York City law firms, as well as having been Litigation Counsel to a bank holding/financial services company, a General Counsel, and for 5 years the President and CEO of a cancer genomics company, accepts only matters to which he is confident that he can devote his full attention. As a former American Arbitration Associate Neutral, Mr. Maione also was aware of, and appreciated the art of mediation and conciliation and is an advocate of utilizing his skills to help clients amicably resolve business disputes before they proliferate into costly litigation. Not every matter should go to trial, and when the client’s finances are at stake the “principle of the thing” takes on a hollow ring.

The Services:

Mr. Maione provides all clients with an estimate or budget, assessing the costs and expenditures which the client can be expected to incur over the life of the matter if it is one which appears destined for trial, as well as a reasoned expectation of how long it may take to accomplish the desired goals. In this fashion, the client, be it corporation or individual, always knows what to expect and how much it will cost. This process allows the client to make a well-reasoned decision about whether to proceed while serving to avoid surprises.

Practice Areas

Mr. Maione has broad experience representing financial institutions such as banks, securities clearing and transfer companies, broker-dealers and other commercial enterprises as both plaintiff and defendant in civil litigation, arbitration, and administrative proceedings.

In addition to matters governed by the Carmack Amendment and the Warsaw and Montreal Conventions. His business experience as CEO in leading a major innovator in the cancer diagnostic industry also gives him the unique advantage of understanding business operation

Securities Litigation and Arbitration
