Proof posture
The complaint and later proof should connect the named plaintiff, the account, and the claimed balance with specific facts.
Kentucky's 5-year SOL on open accounts and credit cards (KRS § 413.120(1)) is shorter than most states. Combine with KRS § 413.320 borrowing for DE-issuer accounts (3 years), per Conway v. Portfolio Recovery Associates, 13 F. Supp. 3d 711 (E.D. Ky. 2014). The Kentucky Consumer Protection Act (KRS §§ 367.110-367.300; private right of action under § 367.220) is generally unavailable against third-party debt buyers due to privity-of-contract requirements applied by Kentucky federal and state courts, though limited exceptions may exist where the original creditor remains a party or the collector's conduct is independent of the underlying contract. The federal FDCPA (15 U.S.C. § 1692 et seq.) is the primary counterclaim vehicle in debt-buyer cases, with Stratton v. PRA, 770 F.3d 443 (6th Cir. 2014), and Currier v. First Resolution, 762 F.3d 529 (6th Cir. 2014), as the leading 6th Circuit authority.
