Debt validation not responded to. What can i do?

You are entitled to ask for validation in discovery. If they can't provide it, ask the judge to dismiss the case with prejudice. Take your documentation showing that you've previously demanded validation with you to court. The judge may find it enlightening.

They often do not respond to debt validation request, If I were you I would sent the request certified mail, return receipt requested, that way they will have to sign for it and if they still don't provide you validation you have the request to show the court. Also file a copy of the request for validation with the courthouse that the summons was issued then it will be on record. You just need to take a copy of the request that you send to them to the prothonotary, clerk of courts, they will file it in the case file.

I agree with what was posted above, just wanted to add that you need to show up. No show=default judgment, once they get it it's not easy to get it vacated.

I had a junk debt buyer get a default judgment against me from a car repo, the repo was way out of the SOL but I didn't show up to court. It's gone now but if I would have shown up it would have never been granted.

Demand full proof of debt in court through the discovery process. Also inquire about a counter suit for using the court system to collect without answering a valid dispute of this account.

So what would I need to do during mediation pertaining to this case? Any suggestions?
