We have Family Law, with specific guidelines that determines who gets custody of children, division of community property, etc in the event of divorce. Gone is the day when everything automatically went to the woman because she was PRESUMED to be spotless and perfect: now we have a much fairer code of law but it is lengthy, is a specific legal specialty, and a separate degree is required to practice that exacting branch of law.
French law now flirts with Sharia abuses, where in the case of legal separation the man gets everything. Mexican law suffers the age old abuse where the woman still gets everything. American Statute is much fairer than either.
Rocmike you forgot to mention Atheists.
