First, a DV request is only timely if it is sent within 30-days after receipt of the collection ("dunning") notice from the debt collector.
If they sent dunning notice more than 30-days ago, a DV request would be untimely, and could simply be ignored.
Second, even if timely, a DV request under the FDCPA does not impose any requirment to send validation within any period.
A timely DV only imposes a cease collection bar, which prevents continued collection activities until they first send the requested validation.
Third, what is requried to comprise adequate validation is subject to interpretation. The courts have generally held that they do not need to send documentation, they need only investigate and provide a statement that they have found the debt to be legit. You will find some appellate case law that interprets FDCPA 809(b) as requriing some documentation, but that is not the norm.
Ultimately, since the issue of adequate validation is subject to interpretation of the statute, it is left to the judge in your civil case to make that determination on a case by case basis. However, if you challenge the adequacy of validation in court, you are likely to be asked whether you consider the debt to be legit. If you answer yes, then you have no basis to request validation under the FDCPA, and the issue will be moot.
