However, there are several situations in which a pre-operative or postoperable contract is cancelled or invalidated. This implies that while anticipations or a posteriori can protect a lot of assets and business, there are many things they can`t do. If a marriage does not contain provisions contrary to the law, it is considered null and void and unenforceable. Marriage contracts were the norm until a few years ago. Today, however, many couples opt for a terminated contract in order to end the dispute over money. Instead of talking about the distribution of property in case the couple separates, a follow-up contract usually clearly determines the couple`s financial responsibility and how they distribute their income, who pays for what, and who saves what. For example, one could save for children`s college, while the other would save for vacations or rest plans. .
