How do I find out if all my debtors have received a copy of my bankrupcty discharge?

Who handled your bankruptcy? That is who you should be contacting to know if you are discharged?

If you properly listed the creditors with their correct addresses, then they should be notified of your discharge.

Agreed, you don't "find out" you know it happened since the court sent it out to everyone on your debtor list.

You also have a copy, and they were barred from collections anyway when you filed.

Why do you think this is a issue , and why are you worried about it ?
