Abstract This article aims at providing an overview of cross border marriages from a Brazilian law perspective. Topics such as (i) marriages under Brazilian law, (ii) rights of spouses and partners, (iii) scope and enforceability of prenuptial agreements and civil law marriage agreements, (iv) trusts and business interests, (v) family dynamics, (vi) taxes and (vii) take away tips, are addressed from a practical standpoint to navigate readers through this sensitive matter. Love has no boundaries is an expression shifted to a whole new level in today’s world. Transportation between countries and continents ceased to be a concern a long-time ago, and the Internet and social media are bringing people closer and closer in absolute disregard of their place of residency. Cross-border marriages are one of the natural side effects of this reality. And if happily ever after is not for everyone, cross-border divorces are side effects as well. In this sense, this article examines marriages from a Brazilian law perspective, including topics involving the rights of spouses and partners under Brazilian law and prenuptial agreements and civil law marriage agreements.
