How long does it take to get the paperwork if I show my discharge of chapter 7 on my credit report?

I think you might be asking how long it takes your discharge to appear on your credit report, but I am not sure. Since I do not work at any of the major credit reporting agencies, I cannot say for sure, but my experience is that this complex information is processed in less than 3 months.

If you listed your credit reports for notices in the case, about a week. If you didn't then it depends on when a creditor informs them.
