By statute effective August 2015, the parties to a forthcoming marriage in Argentina can enter into an agreement whereby they may select either the community property system or a separate property system to govern their marriage. They may also designate the property that each of the spouses will contribute to the marriage and designate the gifts between the spouses. The agreement must be executed by a notarially recorded instrument. To be effective against third parties, the marriage certificate must include a note in the margin specifying the regime chosen. If the spouses wish to modify the agreement during the marriage, the amendment must be made by agreement and by a notarially recorded instrument and the spouses must have been married for at least one year. Any creditors who are thereby affected must object within one year of the time they became aware of the change.
