Which of the following is NOT a requirement for anti-nuptial and post-nuptial agreements?

In the context of anti-nuptial (prenuptial) and post-nuptial agreements, various requirements are established to ensure their validity and enforceability. Among these, the necessity for the agreement to be mutually beneficial is not a formal legal requirement.

While many couples aim for their agreements to be equitable or fair, the law does not mandate that such agreements must benefit both parties in a specific manner or to the same extent. Instead, the focus in legal terms is on the execution of the agreement with the required formalities, such as being in writing, ensuring that both parties have a full and fair disclosure of their financial situations, and providing knowing consent regarding any waivers of rights.

These elements—written form, disclosure, and consent—serve to protect the interests of both spouses. They ensure that both parties are fully aware of what they are agreeing to and that any waiver of rights is made knowingly and voluntarily. However, the idea of mutual benefit, while often a desirable outcome in practice, does not constitute a legal requirement that could invalidate an agreement if it does not occur. Thus, the correct answer is that mutual benefit is not a requirement for these agreements.
