To challenge the validity of a prenuptial agreement, one looks to see if any of the above elements were abused or not satisfied. This can include–
1. Duress- A prenuptial agreement can be voided if one party was pressured or coerced into signing it. Duress also can be shown if the agreement was presented too closely to the wedding date and is not given enough time to think about the terms of the agreement before signing it. Some sources suggest that agreements signed within 60 days of the wedding may be challengeable based on duress. For example, duress has been shown where the wedding is only days away, the invitations have been sent, large sums have been expended, and cancelling the wedding would be costly and embarrassing. Another example is a case where the groom presented a prenuptial agreement just before the bride’s visa was to expire and told her to sign or the wedding would not take place prior to the visa’s expiration date.
2. Lack of mental capacity- Lack of mental capacity can be shown if the agreement was signed when one party was drunk or under the influence of drugs.
