An International Divorce Lawyer in New York

“International family law cases are among the most challenging areas of legal practice. They often involve proceedings in two or more countries at once, requiring careful coordination between legal systems, attorneys, translators, and courts. Jurisdictional issues are key—New York courts can only take a case if one of the parties is legally considered a resident of the state. When children live abroad, New York courts generally defer custody decisions to the courts in the child’s country of residence.”

Elena Giannattasio | Founder, Multi-Jurisdictional Divorce

Why Are International Family Law Cases on the Rise?

Not long ago, international family law made up only a small portion of the family law landscape in the United States. But with globalization accelerating over the past few decades, cross-border relationships have become far more common. This has led to a sharp rise in international marriages—and subsequently, international divorces, child custody disputes, and prenuptial agreements.

As international families grow, so does the need for attorneys skilled in managing the legal and logistical complexities of cross-border family law.

International Law Cases Are Inherently Complex

Family law in the U.S. is regulated state by state. Even cases involving parties from different U.S. states can be complicated. But when international elements are introduced—such as foreign assets, dual citizenships, or children living abroad—the legal terrain becomes significantly more difficult to navigate.

These cases often involve:

  • Differing legal systems and court procedures
  • Language barriers
  • Currency and tax complications
  • Conflicting cultural norms
  • International treaties and conventions

 

That’s why it is absolutely essential to work with an experienced international family law attorney who understands both the U.S. and foreign legal frameworks.

The Most Common International Family Law Issues We Handle

International Divorce
Elena Giannattasio represents clients in divorce cases involving one spouse living overseas and the other in New York. These cases often involve complex financial structures and jurisdictional questions—especially where minor children are involved. We work across borders using New York family courts, international legal cooperation, and skillful negotiation to resolve these sensitive cases.

International Prenuptial Agreements
International couples planning to marry should understand how jurisdiction and residency can impact the enforceability of prenuptial agreements. With divorce laws varying widely between countries, proper planning is essential. We prepare strong, internationally viable agreements for couples planning to live abroad or with assets in multiple countries.

International Child Custody Disputes
When international couples separate and children are involved, disputes over custody and relocation can become extremely contentious. If one parent removes a child from the home country or refuses to return the child from abroad, the other parent may turn to New York courts or invoke the Hague Convention on the Civil Aspects of International Child Abduction. Our office has deep experience in navigating these highly sensitive and urgent legal matters.
