Understanding Debt Collector Dispute Laws: FDCPA, FCRA & Burden of Proof

The FDCPA (15 U.S.C. § 1692) requires collectors to validate debts upon written dispute within 30 days ("disputing debt collector evidence burden of proof"). They must provide: debt amount, creditor name, and proof you owe it ("validating debt collector claims with documentation"). No validation? Collection halts.

FCRA (15 U.S.C. § 1681) governs credit reporting disputes, requiring furnishers (collectors) to investigate inaccuracies within 30-45 days ("debt collector response time evidence requirements").

Statistic: FTC enforces FDCPA; 40% of disputes fail validation due to missing docs.

FDCPA vs FCRA: Key Evidence Differences

Note: Some states extend SOL beyond federal (e.g., CA 4 years vs. 3-year FCRA reporting limit).
