Overview

Cohen Clair Lans Greifer & Simpson LLP is one of the most prominent matrimonial law firms in the United States. Our partners and associates write, lecture and teach throughout the country as well as internationally on important issues relating to matrimonial and family law. We represent individuals and their spouses across a broad spectrum of industries and professions, including finance, real estate, media, sports, entertainment, law, politics, and medicine, and have handled many of the largest matrimonial matters in New York and elsewhere. As a result, we have expertise in negotiating and litigating cases which present sophisticated and specialized valuation issues. We also bring extensive experience toward child custody, with a keen focus on difficult issues such as relocation and parental access. In addition, we regularly draft and negotiate prenuptial, postnuptial and paternity agreements.

Due to our expertise and experience, our lawyers are often called upon to serve as counsel or advisors in jurisdictions across the United States, as well as Europe and Asia.

Our strength lies in our creative skills, honed through decades of focus on family law. Our understanding of the complicated issues we face together with our clients, along with the reputation which precedes us, frequently leads to deftly and efficiently negotiated resolutions. Obtaining a favorable result while avoiding the costs of litigation is our initial approach and ultimate goal.

In the event litigation becomes necessary, our clients benefit from our vast experience and ability. We have faced and prevailed in courtrooms countless times, often on novel issues establishing groundbreaking legal precedent.

We are proud that the clients who we have represented are our greatest source of referrals.
