Thanks for the explanation.

Can the members of the marriage(spouses?) change that?

Here in Spain some autonomous communities (like the states in USA) have community property as default and some others have asset separation as default but when one gets married can decided which one to use

You can get a prenuptial agreement (prenup), but which laws you are allowed to override varies by state, duration of the marriage, the whims of the divorce court, and how diligent you are about keeping assets separate during the marriage. You're probably better off spending your energy on avoiding marrying the wrong person...

In summary you can get a prenup, but it may not matter at all depending on jurisdiction and a variety of circumstances.
