Makes a lot of sense to me!
In the West, property owned by either couple in a marriage is considered to be jointly owned. When there is a divorce, the property gets divided almost equally. Divorces usually result in a lot of acrimony, because, in addition to custody battles for children, one partner usually gets some money or property earned by the other, when the matrimonial pot is split. When there is so much bitterness, why should a divorcee be able to walk away with her ex's kidney?
