When Does the Limitation Period Restart After Acknowledgment of Debt?

In debt recovery and commercial contract disputes, the Limitation Act 1980 sets strict time limits for bringing legal claims. For most simple contract debts in England and Wales, the limitation period is six years from the date the cause of action accrues.

However, this period does not always run continuously to expiry. In certain circumstances, it can restart, extending the time available to bring a claim. One of the most important mechanisms for restarting limitation is a written acknowledgment of debt or a part payment by the debtor.

This article explains when and how the limitation period restarts after acknowledgment of debt, the legal requirements involved, and the practical consequences in commercial debt recovery.

Legal Framework: Acknowledgment of Debt and Limitation

The key provisions are found in the Limitation Act 1980, particularly:

• Section 29 – effect of acknowledgment or part payment
• Section 30 – requirements for valid acknowledgment

These provisions apply primarily to debts arising from simple contracts, which include most commercial trading relationships.

Where valid, an acknowledgment has the legal effect of resetting the limitation clock, starting a fresh limitation period.

When Does the Limitation Period Restart?

Core rule

The limitation period restarts on the date when a valid acknowledgment of debt or part payment is made.

From that date:

• A new six-year limitation period begins (for simple contract debts)
• The creditor gains a fresh window to bring court proceedings

What Counts as a Valid Acknowledgment of Debt?

For an acknowledgment to restart limitation, it must meet strict legal requirements.

1. It must be in writing

The acknowledgment must be:

• In writing (letter, email, invoice response, or signed document)
• Verifiable as originating from the debtor or authorised agent

Oral statements are not sufficient.

2. It must acknowledge the existence of the debt

The communication must clearly show that the debtor:

• Recognises the debt exists, and
• Accepts liability for it in principle

Examples include:

• “We owe this amount but cannot currently pay in full”
• “The invoice is outstanding and will be settled”

3. It must be made by the debtor or authorised representative

Valid acknowledgments can be made by:

• The debtor personally (individual or company director)
• An authorised agent (e.g. solicitor acting on instructions)

Unauthorised statements will not restart limitation.

4. It must relate to a liquidated debt

The rule applies to:

• Fixed, identifiable sums (invoices, loans, agreed balances)

It does not typically apply to:

• Unquantified damages claims
• Disputed or unliquidated obligations (unless liability is clearly admitted)

Part Payment and Its Effect on Limitation

In addition to written acknowledgment, part payment can also restart limitation.

Conditions for part payment:

• Payment must be made by the debtor
• Payment must be referable to the debt in question
• It must be voluntary and not coerced

Once made:

• A new six-year limitation period begins from the date of payment

How the Restart Mechanism Works in Practice

Example 1: Written acknowledgment

• Debt due: 1 January 2020
• No payment made
• Email acknowledging debt: 1 March 2024

Effect:

• Original limitation would expire: 1 January 2026
• New limitation period starts: 1 March 2024
• New expiry: 1 March 2030

Example 2: Part payment

• Debt due: 1 January 2020
• Part payment made: 1 July 2023

Effect:

• Limitation resets on 1 July 2023
• New six-year period runs until 1 July 2029

What Does NOT Restart Limitation

Certain actions do not restart the limitation period:

1. Mere reminders or chasing letters

• Credit control correspondence from creditor
• Payment demands without debtor admission

2. Disputed liability

If the debtor expressly denies liability:

• No acknowledgment occurs
• Limitation continues running unaffected

3. Negotiations without admission

Settlement discussions or “without prejudice” negotiations:

• Do not usually constitute acknowledgment
• Must contain clear admission of debt to qualify

4. Internal accounting entries

• Debtor's internal records alone are insufficient
• Must be communicated to creditor

Legal Requirements Under Section 30 Limitation Act 1980

For acknowledgment to be effective:

• It must be made to the creditor or their agent
• It must be clear and unequivocal
• It must be capable of being relied upon in legal proceedings

Courts interpret these requirements strictly, especially in commercial disputes.

Effect of Restarting the Limitation Period

When limitation restarts:

• The original limitation period is effectively replaced
• A fresh six-year period applies from the acknowledgment or payment date
• The debt becomes fully enforceable again (if previously close to being time-barred)

However:

• It does not create a new debt
• It only extends enforceability of the existing obligation

Commercial Debt Recovery Implications

For creditors

Acknowledgment or part payment can:

• Preserve long-standing debts
• Prevent claims becoming statute-barred
• Extend recovery opportunities significantly

Creditors often seek written confirmation of liability during negotiations for this reason.

For debtors

A careless acknowledgment can:

• Reset limitation unintentionally
• Extend exposure to legal proceedings
• Revive otherwise time-barred debts

Legal wording in correspondence can therefore be critical.

For litigation strategy

Acknowledgment issues often determine:

• Whether a claim is time-barred
• Whether proceedings can proceed at all
• Whether older debts can be included in a claim

Common Scenarios in Commercial Practice

1. Debt collection negotiations

A debtor agrees the debt exists but requests time to pay:

• Likely to restart limitation

2. Partial settlement payments

• Even small payments can reset limitation

3. Email confirmation of outstanding invoices

• Often treated as acknowledgment if liability is admitted

4. Disputed invoices

• If liability is denied, limitation is unaffected

Common Questions from our Readers

Does any email restart limitation?

No. Only emails that clearly acknowledge liability for the debt will restart limitation.

Does making a payment plan restart limitation?

Yes, if it includes admission of liability or a part payment is made.

Can limitation restart more than once?

Yes. Each valid acknowledgment or part payment restarts a fresh six-year period.

Does acknowledging part of a debt restart the whole debt?

Yes, generally the acknowledgment can restart limitation for the entire outstanding balance if it refers to the debt as a whole.

Key Takeaways

The limitation period for debt claims in England and Wales can restart when there is a valid written acknowledgment of debt or a part payment, under the Limitation Act 1980. When this occurs, a new six-year limitation period begins from the date of acknowledgment or payment. The acknowledgment must clearly admit liability and be made in writing by the debtor or an authorised agent. Casual correspondence or disputed liability does not restart limitation. In commercial debt recovery, this principle plays a critical role in determining whether otherwise time-barred debts remain legally enforceable.
