When a debt buyer cannot prove it owns the debt
A company that bought your debt has to prove it owns your specific account before it can collect in court. That usually means a chain of sale documents running from the original lender to the plaintiff, each covering your account. New York requires the complaint to name every prior owner and the date of sale, and Florida requires a debt buyer to give you written notice of the assignment at least 30 days before any action to collect.

The company suing you is not the bank you borrowed from. It bought your account, often years after you stopped paying, sometimes after two or three earlier buyers. The complaint says it owns the debt. The question is whether it can prove that for your account.
This post explains what "standing" means in a debt buyer suit and what the law in New York and Florida requires. It does not cover New Jersey court rules on this point.
What ownership looks like on paper
Debts are usually sold in bulk: thousands of accounts in one sale, described in a purchase agreement with a list of accounts attached. To prove it owns yours, a buyer generally needs:
- Every link. A document for each sale, from the original lender to each later buyer and finally to the plaintiff.
- Your account in each link. A bill of sale that says "all accounts in the attached file" proves little unless the file, or an excerpt, shows your account.
- The account itself. The contract or charge-off statement and records showing the balance.
- A witness who can back it up. Someone able to lay a foundation for the records, not just sign a form.
Gaps are common: a missing middle sale, a bill of sale with no account list, or an affidavit from someone at the last buyer vouching for records created by the first.
What New York requires
The Consumer Credit Fairness Act built ownership into the pleadings. A consumer credit complaint must state whether the plaintiff is the original creditor, and if not, the date of sale and each prior owner, and must attach the contract or charge-off statement (CPLR 3016(j)). A plaintiff seeking a default judgment must file affidavits including the chain of title (CPLR 3215(j)).
Before a suit, New York's DFS rule requires third-party collectors and debt buyers to substantiate a debt within 60 days of a written dispute, and not to collect until they do (23 NYCRR 1.4). In New York City, for accounts where a validation notice is required on or after September 1, 2026 (excluding accounts purchased before that date), a collector that cannot verify a disputed debt within 60 days must send a Notice of Unverified Debt that travels with the account. Licensed agencies must also record who sold them each purchased debt, when, and for how much.
What Florida requires
Florida lets a creditor assign the right to collect a consumer debt, but "the assignee must give the debtor written notice of such assignment as soon as practical after the assignment is made, but at least 30 days before any action to collect the debt" (Fla. Stat. § 559.715). The same section makes the assignee a real party in interest that may sue on a defaulted debt assigned to it. Florida's collection statute also bars claiming, attempting or threatening to enforce a debt when the collector knows it is not legitimate, or asserting a legal right it knows does not exist (Fla. Stat. § 559.72(9)).
A Florida suit on a written contract generally must be filed within five years, and on an open account or oral contract within four (Fla. Stat. § 95.11). See Florida.
When a gap becomes a federal claim
Debt buyers whose principal purpose is collecting debts are debt collectors under the FDCPA (15 U.S.C. § 1692a(6); Henson v. Santander, 582 U.S. 79 (2017)). A collector may not falsely represent the character, amount or legal status of a debt (§ 1692e(2)(A)), or threaten action it cannot legally take or does not intend to take (§ 1692e(5)). After a timely written dispute, it must stop collecting until it mails verification (§ 1692g(b)).
Regulators have acted on this exact problem. In 2015 the CFPB announced orders against Encore Capital Group and Portfolio Recovery Associates over practices including robo-signed affidavits and suing without documentation, and in 2017 it ordered Transworld Systems to pay a $2.5 million civil penalty over collection suits it could not prove, as the CFPB described them. See Midland, Portfolio Recovery, LVNV and Transworld, and the Encore and PRA orders.
The FDCPA provides actual damages plus statutory damages of up to $1,000, and it requires a collector found liable to pay the consumer's reasonable attorney's fees and costs. The deadline is one year from the violation. If you have been sued, do not ignore the papers: the answer deadline is short. See sued by a debt collector and a debt suit in NYC Civil Court. For New York and New Jersey generally, see New York and New Jersey.
What to do this week
- List every name on the complaint and its attachments: original lender, each buyer, the plaintiff.
- Check each link for a document that identifies your account.
- Dispute in writing with the collector if you are still before a suit; the letter builder writes a validation request.
- Answer on time if you have been sued, and raise standing and the statute of limitations.

Common questions
What is a chain of title for a debt?
It is the series of sales that moved your account from the original lender to the company suing you. Each sale should be documented, usually by a bill of sale and an assignment, and each should identify your account, often through an attached list of accounts.
Is a debt buyer covered by the FDCPA?
A debt buyer whose principal purpose is collecting debts, or that regularly collects debts owed to another, is a debt collector under the FDCPA. A company collecting debts it bought for its own account may be outside the definition if it does neither.
Does a missing document mean I win?
No. It means the plaintiff has a gap it must fill with admissible evidence. Raise it in your answer and let the court decide. Never promise yourself a result from one missing page.
