My question involves bankruptcy in the state of: Texas

My ex-wife owes me $25k as written out in our divorce decree (I do not owe her anything). In total, she is now $100k in debt and filling for bankruptcy--

Since I am one of her creditors (the 25k she owes me is in my name), I received a letter in the mail today telling me I need to defend the debt she owes, or it will be forgiven. How do I protect the money she owes me from being erased with all of her credit card debt?


Thanks in advance for any help!
