Bankruptcy effects/new lawsuit

I filed chapter 7 Bankruptcy and was discharged and all over in 2009. Now I have found out that my ex hid assets from me at time of Settlement in 2001. I am filing a lawsuit and need to know if I need to ammend a chapter 7 to include the new lawsuit or not. I am afraid that the atty for my ex will file judicial estopple and go for a summary judgement regarding this if she can. Any advice. I am working without an atty. Thanks

You need to discuss these issues with an attorney who specializes in bankruptcy.
