Your trustee meeting takes place 21-40 days after you file for bankruptcy. Then, about 60 after your trustee meeting, your debt will be officially discharged.
This means that 80-100 days after you file for bankruptcy, your debt will be officially discharged. You should, however, tell you creditors that you're filing for bankruptcy as soon as you start the process. Often times, this leads creditors to stop harassing debtors.
