A named partner of the Firm, Dan Rottenstreich is one of the most well-regarded matrimonial lawyers in New York City.

Mr. Rottenstreich combines well-honed litigation skills with a deep knowledge of accounting from his training as a CPA, to take on extraordinarily complex financial cases. His reputation and success as a trial lawyer frequently allow him to secure favorable settlements, often without setting foot in court. He is also a proponent of alternative dispute resolution, including mediation and arbitration.

“He is a great guy and a terrific litigator.” Another interviewee notes: “He is outstanding, he has really good business sense. He can be tough but also kind.”

Mr. Rottenstreich’s record in the courtroom is exemplary. He was lead trial counsel in the largest equitable distribution case ever tried in New York State, where he secured a complete victory for our client. He was again the lead trial counsel, representing a prominent hedge fund principal, whose case settled mid-trial on extremely favorable terms. Mr. Rottenstreich’s recent cross-examination of an adverse party during an arbitration resulted in the testimony being halted, the witness being forced to admit he had perjured himself, and his counsel withdrawing from representation. At trial in another matter, the judge stopped the adverse party’s testimony and admonished the witness for lying. The case settled on very favorable terms shortly thereafter.

Mr. Rottenstreich has handled acrimonious custody cases when appropriate custody arrangements could not be agreed upon, including several cases involving underlying mental health or substance abuse issues. Notwithstanding his extensive litigation experience, Mr. Rottenstreich makes every effort to resolve cases fairly, quickly, and efficiently. He settles far more cases than he tries.

In 2020 and 2021, Mr. Rottenstreich was ranked by Chambers, a rare honor for a New York matrimonial lawyer. ln 2018, Mr. Rottenstreich was named one of “Hollywood’s Troubleshooters: Top 20 Lawyers for Divorces, Plea Deals and Death Plans” by the Hollywood Reporter. Since 2013, Mr. Rottenstreich has been voted a New York family law “Super Lawyer” each year by his peers, as well as one of New York’s “Best Lawyers in America.” He is a past member of the board of directors of the New York University Alumni Association. He was also a legal consultant to Showtime’s award-winning series The Affair for seasons two and three.

“He is no-nonsense, down-to-earth, responsive and a really good guy.” Other sources in New York describe Rottenstreich as “excellent” and “a real player in this market.”
