What if I suspect that my husband is hiding something?

An agreement is also not valid should there be "fraud in the inducement," that is, certain lies that influenced you to sign the agreement. If this "hiding something" constitutes fraud, your agreement is not valid. For example; your spouse told you that he or she did not have any property interest in the speedboat at his best friend’s lake house. It turns out, after you signed the separation agreement that he owns half the speedboat, and it is worth $20,000.

Deception is not a wise move when it comes to separation and/or divorce. The judge will most likely pick up on it and once it is evident, your credibility will be worth nothing in the eyes of the court.
