Legal consequences for infidelity sounds great. I do think that castration, public nudity humiliation, islamic stoning or islamic hanging may be too extreme. Plus, infidelity consequences need to be treated equal for men and women. Financial disadvantage would probably be more fitting. My mother did voluntary financial (from her guilt/shame) by not taking anything but her car from my father. I think mandatory financial consequences should be the law.
One bitter point for me was having to buy out my XW for alimony to the tune of $40 G. It seemed like I was being punished and she was being rewarded.
