New York City Divorce Lawyer

What sets us apart from even some of the best divorce lawyers
in New York City?

Ivy League lawyers and staff from Cornell, Columbia and Princeton.

Gordon Diefenbach is widely regarded by clients and colleagues as a talented trial lawyer. The Diefenbach law firm is located in the heart of the Wall Street financial district in the New York Information Technology Center concentrating in New York divorce law, family law, child custody disputes and complex divorce litigation, as well as in tort litigation. Our law firm has been in existence since 1999, and Mr. Diefenbach has been a trial lawyer for even longer, 25 consecutive years. Our lawyers and staff are all from Ivy League schools with large law firm backgrounds prior to joining us. Ever innovative, the firm is at the forefront of benefiting from the evolving merger between Information Technology (IT) and the law. To be truly successful in this area of the law, an attorney needs years of experience and intelligence. We have both.

Our Mission Statement

We love what we do and our mission is to fulfill each client's goals, and we are good at getting clients what they want. Every client has different goals: some want the children, some are concerned with a significant cash pay-out in their divorce, others seek to maintain the ownership interest and equity in professional practices. We will seek to fulfill that goal through every legal channel within the bounds of the law. We counsel you of all your rights during divorce, child custody, separation, and family court proceedings, among others. We will leave no stone unturned to protect those rights. We will be loyal only to you. We have long been the go-to law firm for even other lawyers. When other lawyers did not wish to take on financially complex divorce cases, or high-conflict child custody divorces on some of New York's nastiest divorces, we did.

Our firm is positioned to obtain legal resolution of the most challenging divorces, when the stakes are high and when you need the dispute to be resolved in your favor. Look at our educational credentials and 25 years of trial practice, and compare that to other divorce lawyers who rank high on Google. None of them have that combination. We do. And they pay to get on the first page of Google, we don't. Our reputation gets us there.

Why The Diefenbach Law Firm?

We have the cutting-edge computer technology, high speed T 1 broadband lines, the research tools of Westlaw, LexisNexis and LoisLaw's Online National Library, and the talent to tap into that arsenal of information, as well as long established contacts with some of the best private investigators in the world, to turn any case around. Gordon Diefenbach has been hired on some of the most high-conflict divorce and custody cases ever to hit the New York courts. But just winning the case for a client is half the battle. Top divorce lawyers also have that uncanny ability to obtain the best child custody settlements for their clients, and he is no exception. When compared to other New York divorce lawyers dealing with child custody in New York, he is more deeply concerned with the needs of the children, and will fight hard to give them the future they deserve.

He is keen on attention to detail in every case he handles, which lends to finding inconsistencies in documentary evidence, in financial records, and during cross-examination. More than anything, it is these inconsistencies which destroy the other side's case. "When fighting back false allegations by a spouse, or uncovering hidden assets, get the best divorce attorney in New York you can," he says. One client has said, "He has the levity of a dove and the tenacity of a barracuda."

He has a reputation for being a tough and aggressive Manhattan divorce lawyer, especially in child custody cases.
