What type of misrepresentation can invalidate a marriage?

Misrepresentation involving willingness to engage in marital relations can indeed serve as a basis for invalidating a marriage because it directly touches upon the core basis of consent in any marital agreement. Consent is fundamental to the validity of a marriage, and if one party was led to believe that the other was willing to engage in sexual relations—an essential aspect of matrimonial relationships—then the deceived party's consent is considered compromised.

In family law, the willingness to engage in marital relations implies not just a desire for physical intimacy but also a commitment that is intrinsic to the partnership of marriage. If a spouse misrepresents their intentions or readiness for this aspect of the relationship, it fundamentally impacts the trust and expectations inherent in the marriage.

While other forms of misrepresentation, such as those regarding employment status or educational background, might cause other issues within the marriage, they don’t typically rise to the level required to invalidate the marriage contract itself. They may affect matters like support, lifestyle, or expectations but do not undermine the very foundation of consent in the marriage. Misrepresentation of a family member's assets, similarly, pertains more to financial stability or expectations rather than the consensual nature of the marriage itself.
