The first story at this link says a woman did not disclose her lottery winnings when she filed for divorce, and when the ex husband found out about it two years later, she was required by the judge to give him all the lottery winnings.
Is there a general rule that if you don’t disclose you have to give it all to the other divorcee, or is this just something that judge decided to do in that particular case? Seems a mite harsh to me, though I can imagine if the rule is anything less than “you have to give it all over” there will always be some incentive to play games.
