Before getting married, the default regime is the Community of Acquests, however the couple may change the regime to either a Community of Residue under Separate Administration or The Separation of Estates.
The Community of Acquests (COA)
This is the default marital regime after the marriage. Choosing a CORSA or Separation of Estates before the marriage requires a public deed and if the decision is made after the marriage, they must first obtain permission from the Court of Voluntary Jurisdiction.
The Community of Residue under Separate Administration (CORSA)
CORSA states that whatever assets are gained during the marriage by either of the spouses belongs to the relative spouse. However, in the case of separation or divorce, the residue belongs to each spouse equally.
The Separation of Estates
Separation of Estates deems property acquired by either of the spouses as belonging to that spouse, even after the marriage has been terminated.
