remember you may need to dig deep into your state laws.
DV only carries any legal weight if it's a debt collector and you're within the 30 day window. Exactly when the 30 day window begins is somewhat vague-ish, unless you've just received a notice in the mail. That's a rather potent indicator that the clock has begun ticking and the bell hasn't yet chimed.
If one is in Texas, one can DV a debt collector over a disputed debt at any time under Texas law.
You do have the right to dispute information directly with furnishers of data--IOW, the OC, BofA. There was caselaw on the subject, but now the FCRA states this in no uncertain terms. See §623
However, for it to carry any legal weight, you must first dispute with the CRAs. If you haven't disputed via CMRRR with the CRAs, I'd first do that.
If you're having difficulty persuading one or more of the interested parties to comply with the law, you're going to have to use a bigger hammer.
You might try sending a regular 41 cent letter to BofA. Don't mentioned FDCPA. Just say something like:
You claim I owe you a debt. In accordance with the law, I dispute your claim and demand that you provide me with proof of this debt.
Might be an inexpensive 41 cent solution. If you get nowhere, then I'd head down the MOV path.
When disputing something with an OC, it's a bit of tricky path. Who's right and who's wrong, and I'm not even talking about the debt.
Let's presume for arguments sake that the debt isn't owed by the OP. Did the CRA refuse to follow the law and do their job to investigate, or did the OC refuse to do their job and investigate? You just don't know.
If you follow MOV, you reach a point when you disputed with the CRA, and you're now pressing the OC for information. If the OC says, "No, no, you owe this" when you call, then you dispute with them under §623 and get them to show it's yours. If you know it's not yours, and they won't budge, then you can sue the OC under §623.
OTOH, if the OC says, "Umm, no, we don't show this belonging to you. Our bad, and we've never heard from the CRAs asking for verification", then you continue down the MOV path to press the CRA to do it's job.
