Boies Schiller Flexner is known for bet-the-company litigation, and we understand that nearly every family law case involves not only every dollar you and your family have, but often the most important relationships and most sensitive issues in your life. Whether this is a time of great difficulty or joyful anticipation, we are here to help.

BSF’s Matrimonial and Family Law practice handles some of the most difficult and challenging cases in the world. We work in many jurisdictions, both nationally and internationally. We bring the firm’s successful litigation approach to the full range of issues faced by clients in divorce and parenting actions, including custody, relocation, paternity, allegations of domestic violence, distribution of assets and liabilities, alimony, child support, and the recovery of attorney fees. From complex asset divisions to challenging custody battles, we resolve even the most contentious disputes through trial or negotiation.

Our clients include high-net-worth individuals in business, finance, law, medicine, government, arts, and entertainment, and those that have supported their spouses or partners in achieving success in those areas. The breakups of these marriages often involve extraordinarily complicated financial structures and businesses, and we have a strong track record enforcing our clients’ rights to real estate, private businesses, venture capital, stock options, deferred compensation, and other income.

We have also handled cases with difficult children’s issues such as relocation requests, mental health issues, abuse and neglect, and addiction.

The practice is co-led by attorneys who have decades of experience practicing matrimonial law and are fellows of the American Academy of Matrimonial Lawyers and the International Academy of Matrimonial Lawyers. They have served as expert witnesses on numerous aspects of family law and are recognized in Lawdragon's 500 Leading Lawyers in America. Through relationships forged over many years with other leading lawyers, forensic accountants, pension analysts, and business valuation experts, we can create the litigation and negotiation team needed to reach the best outcome possible.

Like all BSF litigators, we are known for going to trial and arguing appeals, but we have also resolved family conflicts with no or almost no adversarial litigation.  

We understand the need to protect our client’s privacy, to try and keep their cases out of the public eye, or, if that is unavoidable, help them to navigate the media and other information sources to protect them and their families as much as possible.

We also regularly work with couples to negotiate and draft prenuptial and postnuptial agreements. Our group brings its litigation experience to these agreements, which often face legal challenges, in order to craft documents that maximize the ability to enforce them with a minimum of disruption and expense.

We are committed to staying ahead of the curve as social change transforms the definition of marriage and the notion of family. For instance, we represented the plaintiffs in the landmark case Perry v. Brown, which upheld the constitutional right of same-sex couples to marry in California. Our practice will continue to be at the forefront of evolving matrimonial and family law as new legal questions emerge.
