A few years ago the Chinese government stated it was concerned with the number of women marrying rich men then divorcing them and profiting from the result. "Parasite" women. So this is what they did: They enacted a rule that people who marry are only entitled to half of items bought during the course of a marriage (And I think half of earnings, but this I'm not sure about.) But each partner retains ownership of the things they owned before marrying.
This has had some interesting effects. I work and live in China (for 15 years) and here is a conversation I had with one of my female Chinese workmates. Workmate was telling me about her "friend."
"My friend is really clever! Do you know what she did? Her husband already owned a home when they were married, so she would have been entitled to nothing when they got divorced. So she told him over and over how much she dislikes "that old house" until he sold it and bought a new one. Now she gets half the house if they get divorced. Even better, she in fact already owns a house given to her by her parents, that she never told him about. So now, he owns half a house, and she owns 1.5 houses! Isn't she clever?"
I suspect she is in fact the friend and is boasting about her own cleverness.
I think if you're sensible, these laws can protect men (And women.) But if you're foolish like her husband was....you will lose out.
I wish they had these laws in other countries.
Edit: Apparently in a lot of places they do.
