Who owns what in a marriage in Argentina?
In Argentina the default is a community of acquisitions, but couples can choose separation of property by a marriage agreement, which they can change later.

What applies by default
Property acquired during the marriage is shared, and each spouse keeps what they owned before and what they receive by gift or inheritance.
When the marriage ends in divorce
The community of acquisitions is divided equally, and each takes their own property.
A marriage contract
Spouses may make a marriage agreement before the wedding, by public deed, to choose separation of property, and can change the regime after a period of marriage.
What stays your own, and gifts
Property from before the marriage, gifts and inheritances stay personal.
If one spouse is a foreigner
Argentina has its own rules on which law applies, so foreigners should get local advice.
Understand the legal system first
Argentina belongs to the Civil law family. Family law grows out of the legal tradition, so it helps to know how the system works.
