Everybody has missed a major point, is this debt TIME BARRED? This means is it still within your states statutes to seek legal action in court to collect?
If it is truly "time barred" and they try and sue you, then you would use the defense that the debt is beyond your states statute of limitations.
Did you sign any written contracts for the work? if so, then find your states SOL for written contracts. The proper way for the contractor to collect would be to file a lawsuit for a "mechanics lien" on your property and even that has a time limit to do so.
The fact that some collection agency is now trying to collect sounds like the debt was sold to them or they were hired by the contractor to collect.
Under the FDCPA, it is ILLEGAL to threaten anyone by making false statements or sending documentation that simulates a summons for a debt collection that they can not legally take action on! 15 U.S.C. §§ 1692-1692p. § 807. False or misleading representations. (you can download a copy of the FDCPA to read for yourself at the link located in the source area).
They are also required under the FDCPA to send you written notice within 5 days after the initial communication with you of the following:
Proof that they own the debt legally or have been legally authorized to collect it from you.
A complete payment history documented from your original creditor. This requirement was established by the case Fields v. Wilber Law Firm, Donald L. Wilber and Kenneth Wilber, USCA-02-C-0072, 7th Circuit Court, Sept 2004.
A copy of the original loan contract that you signed with your creditor.
Without this information, then the debt has not been validated. If they have not sent you this information, then you need to send a request for validation via certified mail/return receipt requested.
DO NOT ACKNOWLEDGE THE DEBT, DO NOT OFFER PAYMENTS, DO NOT MAKE A PAYMENT. Doing so would reset your states SOL and then they could take legal action.
