What Is International Family Law?

Modern families increasingly live across borders. Thanks to globalization and technological advances, building connections around the world has never been easier. At the same time, as people, businesses, and assets move more freely between countries, legal issues with an international dimension have become increasingly common—and they require specialized legal guidance.

Whenever a family matter involves more than one country, important questions arise: Where should I file my case? Which country's law applies? Will a court decision issued in one country be recognized and enforced in another? Understanding the legal framework that answers these questions is essential to developing the right strategy for your case. This is why seeking advice from an attorney who specializes in International Family Law is so important.

It is also important not to make assumptions. Simply because you are Brazilian does not necessarily mean that your case can be handled in Brazil or decided under Brazilian law.

International Family Law is the area of law that deals with family matters involving an international element. This may occur, for example, when one or both parties hold multiple nationalities, when family members have different nationalities, when they live in different countries, when the family has relocated abroad, when assets are located in another jurisdiction, or when relevant legal acts or events have taken place in a foreign country. These are just a few of the many situations in which international legal issues arise.

International Family Law covers a wide range of matters, including international marriages, cross-border divorce, international child support, international child custody, international child abduction, court authorization for a child's international relocation, intercountry adoption, cross-border recognition of legal parentage, international surrogacy arrangements, and international family mediation.

If you are dealing with a family matter and have asked yourself any of the following questions, it is likely time to consult an International Family Law attorney:

• If I get married abroad, will my marriage be recognized in Brazil?

• As a Brazilian citizen, can I file for divorce in Brazil? If I divorce in another country, will that judgment automatically be recognized in Brazil?

• I own assets in more than one country. Where should the property division take place?

• My fiancé(e) and I want to sign a prenuptial agreement, but we plan to move abroad after the wedding. Where should we begin?

• I live in Brazil, I am married, and I want to change my marital property regime, but I also hold another nationality. Could this affect us if we later divorce?

• I am applying for dual citizenship, and the consulate has informed me that my divorce must first be recognized. What does that mean?

• Will my Brazilian stable union (união estável) be recognized abroad?

• I am in a same-sex marriage. Will my marriage be recognized in another country? If we relocate abroad, what legal issues should we consider?

• If my child is Brazilian but we live abroad, can I file a custody case in Brazil?

• If I have sole custody, may I move abroad with my children without the other parent's consent?

• What could happen if I return to Brazil with my children without the other parent's authorization?

• If my child's other parent and I live in different countries, can I seek child support internationally?

• I live outside Brazil and would like to adopt a Brazilian child. Am I eligible to apply for adoption in Brazil?

• Can my spouse and I adopt a child if we are in a same-sex marriage?

• I am considering fertility treatment abroad. Where should I start?

• I live abroad with my new spouse, and we would like to establish legal recognition of my child's socio-affective parentage. Is that possible?
