If you’ve received a debt collection letter and aren’t sure whether the debt is valid, you have the right to ask for proof before taking any further action.

Why might you question whether a debt is valid?
There are several legitimate reasons why you may want to verify a debt before taking any action.
Common reasons include:
- You don’t recognise the debt
You may not recall taking out the credit or account being referred to. - The amount seems incorrect
The balance may be higher than expected due to added interest, fees, or errors. - You’ve never heard of the company contacting you
The debt may have been sold to a third-party agency, or the contact could be fraudulent. - The debt is very old
You may not have had any contact about the debt for several years, raising questions about whether it is still enforceable. - You believe the debt has already been paid
Records may be incorrect or incomplete. - You suspect identity theft or fraud
The account may have been opened or used without your knowledge. - You were previously in dispute with the original creditor
The debt may have been challenged before being passed on. - You have not received any prior communication
A sudden letter out of the blue can be a warning sign to proceed carefully.
In these situations, it is important not to assume the debt is valid. Instead, you should request proof of the debt before taking any further action.
In many cases, requesting proof of a debt is one of the safest first steps you can take – especially if you don’t recognise the debt or believe it may be incorrect.
In this guide, we’ll explain how to request proof of a debt in the UK, what information you should receive, and include a simple template you can use.
What does “requesting proof of a debt” mean?
Requesting proof of a debt means asking the company to provide evidence that:
- the debt exists
- the amount is correct
- you are legally responsible for it
- they have the authority to collect it
This is sometimes referred to as “proving the debt” or “requesting validation”.
When should you request proof?
You should consider requesting proof if:
- you don’t recognise the debt
- the amount seems incorrect
- the debt is very old
- you believe it may be a mistake
- you suspect the letter could be a scam
In these situations, it’s important not to assume the debt is valid without checking.
How to request proof of a debt (step-by-step)
Step 1: Do not acknowledge the debt
Avoid confirming that the debt is yours until you have seen proper evidence. Acknowledging a debt in writing may have legal implications.
An example of what NOT to do could be as simple as writing “I can’t afford to pay this debt right now” – this COULD be intepreted as you acknowledging the debt is yours, resetting the 6-year limit and making a statute barred debt enforceable once more.
Step 2: Write to the company
Send a written request asking for proof of the debt. This creates a clear record of your communication. See our copy-and-paste template below for one way to do this.
Step 3: Keep copies of everything
Keep a copy of your letter or email, along with any responses you receive.
Step 4: Wait for a response
The company should provide evidence before continuing to pursue the debt.
What should a legitimate response include?
A legitimate response should clearly show:
- where the debt came from (such as the original creditor)
- how the amount has been calculated
- evidence that you are responsible for the debt
- proof that the company has the legal right to collect it
For example, this may include account statements, a copy of the agreement, or a notice of assignment.
If this information is not provided, you may have grounds to dispute the debt.
Template: Request for proof of debt
You can use the following template:
I do not acknowledge this debt. Please provide evidence that I am liable for this amount and that your company has the authority to collect it.
Please include details of the original creditor, a breakdown of the amount claimed, and any relevant documentation supporting your claim.
What to say vs what NOT to say
When responding to a debt collector, the wording you use matters. Some phrases may unintentionally acknowledge a debt, while others help protect your position.
| ❌ What NOT to say | ✅ What to say instead |
|---|---|
| “I can’t afford to pay this debt right now.” | “I do not acknowledge this debt. Please provide evidence that I am liable for this amount.” |
| “I owe this but need more time to pay.” | “Please provide full details of the alleged debt, including the original creditor and supporting documentation.” |
| “I’ll pay something towards it soon.” | “I am seeking clarification on this matter before taking any further action.” |
| “I recognise this account but disagree with the amount.” | “I do not acknowledge liability for this debt. Please provide a breakdown of the amount claimed.” |
If you are unsure about a debt, it is always safer to use neutral wording and request proof before making any statements that could be interpreted as an acknowledgement.
Should you contact them by phone or in writing?
In most cases, it is better to communicate in writing.
This gives you:
- a clear record of communication
- time to consider your response
- protection against misunderstandings
What happens if they cannot provide proof?
If the company cannot provide sufficient evidence:
- they may not be able to enforce the debt
- you may be able to dispute or challenge it
- further action may not be appropriate
However, it’s important to review any response carefully before making a decision.
Key takeaway
Requesting proof of a debt is a simple but powerful step. It allows you to verify whether a debt is valid before taking any further action and helps protect you from mistakes or potential scams.
