federal bankruptcy exemption laws

How does the Federal Bankruptcy Exemption Wildcard work?

What is the wildcard under the new laws and how can it be applied?

I think you asked this question before and I answered it already. You get your $1075 personal property exemption and you can stack your $10,775 homestead exemption to the extent that you have not used it to protect a homestead. So absent protecting any equity in your house, you get a total of $11,850 of personal property exemptions.
