Here's how you do it.
If you're serious abour protecting your dough you can do one of 2 things....
a) hide your assets from her.
b) tell her from jump (before yall even get serious) that no matter what any broad you marry, will have to sign a prenup.
Don't leave her with nothing. Work out a deal where you give her money/assets, just nothing near half.
Here's a story though. Hoes are ruthless as fukk. My boy got engaged to this broad (I told him he was dumb...didn't listen to me). So they buy a house together. When it comes time to sign the papers, they're both out of the country and they agree to let the broad's dad sign the papers. They end up calling off the wedding and breaking up. Months later this dude gets SUED $20K by her claiming he owes her the $$$. He couldn't fight it cuz he never signed the papers.
Protect yourselves...and if you don't want to, just understand what you could potentially lose.
I won't be going the prenup route, but my girl makes good bank, has a whip and property so eventhough I can get fukked over...the chances are not as high. Plus...I've put my mom on every property I own. I'll just increase her ownership prior to shacking up.
ON THE FLIPSIDE:
I know a dude who got married..they were together like 6 years. They got divorced said "fukk the lawyers", they sold the crib and split the profit down the middle and wen their separate ways. A divorce isn't always a death sentence.
A lot of it has to do with the quality of the person you're with.
Marry a woman with a career that makes good money and has assets. Stop marrying them fat ass, bum bytches. If you're supporting a girl, you deserved to get taken.
