Whatever problems divorce law has, marriage is a voluntary contract. You could enter into an even more lopsided business partnership, with the difference that you could actually set out penalties for breach. In most jurisdictions, if your spouse abandons you little time after your marry, you're mostly going to be returned to the status quo ante, because assets they have before you marry or that are donated to them/inherited by them do not count as common property.
