During my legal career I have seen individuals who were defrauded by someone and then the perpetrator files for Chapter 13 bankruptcy. The perpetrator hopes to walk away from the damages that they caused by paying a small amount to the creditors. Chapter 13 is a way to do that — but not always.
Since 2005 when bankruptcy laws changed, creditors can object to debtors who submit false financial statements, commit fraud by taking money under false pretenses, taking money while acting as a fiduciary, wilfully or maliciously injuring another and other situations even if the debtor files for Chapter 13 bankruptcy.
The bankruptcy court can enter a non-dischargeable judgment even if the debtor dismisses the entire bankruptcy proceeding after you file your complaint. If the court agrees with your position, a debtor could be required to deal with the debt after the bankruptcy plan is approved. If you have had this kind of issue there are options.
