A creditor has demanded payment after I have filed for bankruptcy, what can I do?
This is where the automatic stay protects the debtor. An automatic stay is a process in bankruptcy law that halts actions by creditors (with certain exceptions) to collect debts from an individual who has declared bankruptcy. If a creditor attempts to repossess your property without the permission of the bankruptcy court, after your case has been filed, it becomes a violation of the automatic stay. If a creditor takes possession of property you own (a vehicle for example), they must return it immediately.
The court has the ability to punish creditors who deliberately violate the automatic stay and the creditor is liable to the debtor for harm caused!
