charliehall, you’re mistaken. Torah law trumps secular law. if the Torah says all the assets are his, even if secular law says 50/50 in divorce, she would not halachicly be allowed to demand that in secular court.
the only thing the secular divorce court should be asked to do (by either side) is to issue a divorce certificate. they should not be asked or made involved in asset separation, as that is a halachic matter. both sides can advise the court they dont want the court to decide how to separate the marital assets. there is no reason the court couldnt accommodate that request if it is agreed to by both sides (as it should be) that they’ll separate the assets in a halachic manner outside of court. and even if the court issued a ruling on asset separation that differs from what the Torah says that, gives her more than she is halachicly entitled to, she would be halachicly required to return to him any funds or assets that she wasn’t halachicly entitled to.
