The laws and rules in each state are different. In Massachusetts, anyone involved in a divorce action fills out a financial statement, where one lists the value of both the obvious (weekly income, value of property, value of 401k) and the obscure (firearms, crops and livestock).
After you fill out the financial statement, you sign it just below a statement that reads (and the bolding/capitalization is on the form, not this writer's emphasis):
<font face="Verdana, Arial, Helvetica, sans-serif" size="2">I certify under the penalties of perjury that the information stated on this Financial Statement...is complete, true, and accurate. I UNDERSTAND THAT WILLFUL MISREPRESENTATION OF ANY OF THE INFORMATION PROVIDED WILL SUBJECT ME TO SANCTIONS AND MAY RESULT IN CRIMINAL CHARGES BEING FILED AGAINST ME.

And p.s.: to whoever suggested a pre-nup as a solution: Don't be so sure. Depending on the state, and especially if the marriage has lasted for 10, or even 5, years, the pre-nuptial agreement may hold very little water.
