Debt Validation Letter for Old Debt — Free Template
Debt buyers often purchase very old accounts and try to collect them years later, sometimes with incomplete records. A debt validation letter for an old debt asks the collector to prove the debt is yours, how much is owed and who owns it, before you make any payment or promise that could affect your rights.

Re: Dispute and request for validation of debt — account or reference number [Account or reference number on the notice]
To whom it may concern:
I am writing in response to your notice dated [Date of the collector's first notice] about the account referenced above, in which you claim I owe [Amount the collector says you owe ($)].
I dispute this debt. I am not refusing to pay a debt I owe; I am asking you to show that this debt is mine and that the amount is correct. This letter is my written dispute and my request for verification of the debt, and for the name and address of the original creditor, under the Fair Debt Collection Practices Act, 15 U.S.C. § 1692g(b). Under that section, when a consumer disputes a debt in writing within the 30-day period after receiving the collector's initial notice, the collector must stop collecting the debt, or any disputed part of it, until it mails verification to the consumer.
Please provide:
1. The name and address of the original creditor, and the account number used by that creditor.
2. The amount you claim I owe, with an itemization showing the balance when you obtained the account and any interest, fees or charges added since, and any payments or credits applied.
3. Documentation showing that this debt is mine, such as a copy of the signed agreement or the original creditor's statements.
4. Documentation showing that you own this debt or are authorized to collect it.
Until you have provided verification, please do not continue collection activity on this debt. If you report this account to any credit bureau, please report it as disputed.
Please communicate with me about this debt only in writing, by mail to the address above. Do not call me at home, at work or on my mobile phone.
Please send your response to the mailing address above. I am keeping a copy of this letter and proof of mailing for my records.
Sincerely,

Time limits on old debts
Every state sets a time limit, often called a statute of limitations, for how long a creditor or collector can sue over a debt. The length varies by state and by type of debt, and the rules on when it starts can be complicated. A debt past that limit is often called time-barred.
Federal rules prohibit debt collectors from suing or threatening to sue on a time-barred debt. A collector may still ask you to pay voluntarily, so it is important to know where your debt stands before you respond.
Be careful with payments and promises
In some states, making a payment, even a small one, or acknowledging the debt in writing can restart or extend the time limit to sue. Do not pay or agree to a payment plan until you have verification and understand your state's rules.
The validation letter is written to dispute the debt without admitting it is yours, so it does not acknowledge the debt. Keep your phone conversations short or avoid them by choosing written-only contact.
Credit reporting is a separate clock
How long a debt can appear on your credit report is a different rule from the time limit to sue. Under federal law, most negative accounts, including collections, can be reported for up to seven years from when the original account first became delinquent, and a sale of the debt does not restart that period.
If an old debt shows a recent date of first delinquency on your report, dispute it with the credit bureaus. That is a common error with resold debts.
What to do, step by step
Check the date on the first notice
Find the first written notice this collector sent you. The 30-day window to dispute generally runs from when you received it, and the notice itself usually states the date by which to dispute. Send your letter well before then.
Fill in the details
Answer the questions above using the collector's name, address and reference number exactly as printed on the notice. Don't admit the debt is yours or promise any payment.
Send it by certified mail
Mail the letter by certified mail with return receipt to the collector's dispute address. Keep a copy, the mailing receipt and the green return card together.
Watch for a response
Until it mails you verification, the collector should not continue collecting the disputed debt. Keep a log of any calls or letters you receive after it gets your dispute.
Review what they send
Compare the verification with your own records. If the debt still isn't yours or the amount is wrong, respond in writing and consider disputing the account with the credit bureaus.
What if the collector ignores your letter?
If you disputed in writing within the 30-day period, a collector that keeps collecting the disputed debt without first mailing you verification may be violating the Fair Debt Collection Practices Act. Keep a written record of every call, letter and text you receive after it got your letter, with dates and times.
You can file a complaint with the Consumer Financial Protection Bureau at consumerfinance.gov and with your state's consumer protection office. Complaints are free, and the CFPB forwards them to the company and asks for a response.
The FDCPA also lets consumers sue collectors that violate it, for actual damages and statutory damages, plus court costs and legal fees in a successful case. If a collector sues you over the debt, never ignore the court papers: respond by the deadline, or you risk a default judgment. A legal aid organization can help if money is tight.

Frequently asked questions
Can a collector sue me for a very old debt?
Collectors are not allowed to sue or threaten to sue on debts past the state's time limit. But if they do file a lawsuit, you must respond to it and raise the time limit as a defense; a court generally will not apply it for you if you ignore the case.
Will sending a validation letter restart the clock?
A letter that disputes the debt and asks for verification, without admitting it or promising to pay, is generally not treated as an acknowledgment. Avoid adding language that says the debt is yours or that you will pay.
Should I just ignore a collector on an old debt?
Ignoring letters is risky, because you may miss a lawsuit or allow inaccurate reporting to continue. Sending a validation letter costs little, protects your rights, and gives you the information you need.
How do I find out my state's time limit?
Check your state consumer protection office's website or a legal aid organization's website, which often explain the rules in plain language. Look up the limit for your type of debt, such as a credit card or written contract.
What happens if I send a debt validation letter after 30 days?
You can still dispute a debt and ask for proof at any time, and many collectors will respond. But the specific requirement to pause collection until verification is mailed applies to disputes sent within the 30-day period after you receive the collector's initial notice. That's why it pays to act quickly.
Does sending a debt validation letter mean I admit the debt?
No. The letter disputes the debt and asks the collector to verify it. Avoid adding anything that acknowledges the debt is yours or promises payment, and don't make a partial payment while you wait, since in some states a payment can affect the time limit for suing on an old debt.
