When there is lack of disclosure, the court will look at whether the agreement is fair and reasonable under the circumstances. If the agreement is fair, the court might still uphold it even without full disclosure. To determine fairness, the court will look at various factors such as the situation of the parties, their ages, assets and income, family obligations and ties, circumstances leading to the execution of the agreement, actions after marriage, needs of the one who gave up something, and whether that person can live as comfortably after the death of the other as before the marriage.
