Having these options is common in other countries too afaict (with some minor differences)

I would be really surprised if the US didnt have these options too…

It's more that these are the only options. No other laws govern marriages. I'm sure other countries have sensible ones too. In the US they have all matter of legal dispute because it's too wide open.

Of course. After divorce, men do better financially. Women are happier. Men dont loose everything in divorce.

Absolute nonsense.

Just living together, informally, is already enough for the woman to take half your assets as it's already considered `Partial Community of Property`.

I can't think of anything where Brazil is generally superior to the US in terms of law.

In Islam, we have it much simpler. There's a dowry paid to the woman that becomes her property. Other than that, each person leaves with their own assets they came in with. If, during marriage, they acquired assets they decided to split half way (or any other percentage), that split holds post divorce.

> Universal Community of Property - applies to all property before and after the marriage; in case of divorce all property is split 50/50

This should not even be an option. If you worked your ass off to acquire wealth before marriage, someone new into your life should not be entitled to that.

You can definitely make a fair argument for wealth built together as partners. That is really fair. They can even have 100% of that. But wealth accumulated before that should not even be up for discussion as there was 0 contribution from the other partner.

This is inseparable from inheritance law. If that wasn't an option all of that wealth would go to other family members. Some people (or a lot of them) trust their spouses more than extended family and would not care to leave wealth to people other than their own family.

Some people want that. It also has religious implications, some people believe the Bible says that's how marriage should be.

But you have to go out of your way to choose it.
