My sister amended her bankruptcy to include my loan after promising she wouldn't. I never got served so did not know about my debt being added on to her bankruptcy. I went ahead and sued her and won a Default Judgment against her for the full amount. My attorney and I were both ignorant of my inclusion in her bankruptcy. Now what can I do? I have heard that she can now sue ME and win damages. How can that be if I never was notified? I have a copy of her Proof of Service on me, and it appears legal and proper.
