Actually, legally the judge was in the wrong. You had an item that was worth $2 million dollars. You owned the lottery ticket before the divorce.
So even if you waited to cash it until after the divorce, it was still WORTH $1 million at the time of your divorce. You only waited to try and game the system.
But you’re required to disclose ALL items you own, and split them 50/50. A $2 million winning lottery ticket has $2 million in financial value.
I suspect if your ex husband was to appeal the case, he would actually win the appeal. But I don’t know if he’s allowed to appeal a civil case.
I suspect the judge was sympathetic to women (ie: sexist and biased), or the judge just hated cheaters (I don’t blame him/her).
I agree 100% your ex was a scumbag for cheating. But purely legally speaking, you should have owed him the $1 million, as a marriage splits ALL ASSETS 50/50, that includes any lottery tickets you had purchased prior to the divorce.
