What Is the Limitation Period for Settlement Agreement Disputes?

Settlement agreements are commonly used in UK employment law to resolve workplace disputes and terminate employment on agreed terms. They are legally binding contracts, usually signed in exchange for a financial payment and a waiver of employment-related claims.

Disputes can still arise after signing, particularly where one party alleges breach of the agreement, non-payment of settlement sums, or issues relating to the validity of the agreement itself. The limitation period for bringing such disputes depends on how the claim is characterised and which court or tribunal has jurisdiction.

What Is a Settlement Agreement in Employment Law?

A settlement agreement is a legally binding contract between an employer and employee under which:

• The employee agrees not to pursue certain claims (such as unfair dismissal or discrimination)
• The employer agrees to provide compensation or other agreed benefits
• The employment relationship is brought to an agreed end

These agreements must meet statutory requirements under the Employment Rights Act 1996 to be valid, including independent legal advice for the employee.

In many cases, disputes do not concern employment rights directly, but rather the enforcement or interpretation of the agreement itself.

Legal Nature of Settlement Agreement Disputes

Most settlement agreement disputes are treated as:

• Breach of contract claims, or
• Disputes over enforceability or validity of a contract

This distinction is important because it determines the applicable limitation period and forum.

Common disputes include:

• Non-payment of agreed settlement sums
• Disputes over tax deductions or payment structure
• Allegations that the agreement was signed under duress
• Claims that the agreement was misrepresented or misunderstood
• Failure to comply with post-termination obligations (such as references)

Limitation Period: County Court Claims

Standard limitation period: 6 years

Most settlement agreement disputes brought as breach of contract claims in the civil courts must be issued within:

• 6 years from the date of breach

This is set under the Limitation Act 1980, which governs contractual disputes in England and Wales.

A breach may occur when:

• A payment is not made on the agreed date
• A contractual obligation is not fulfilled
• A term of the settlement agreement is violated

Each breach may generate its own limitation period depending on how the contract is structured.

Employment Tribunal Jurisdiction and Time Limits

Employment Tribunals generally do not hear standalone settlement agreement enforcement claims, because these are contractual disputes.

However, settlement agreements may still be relevant in tribunal proceedings where:

• The validity of the agreement is challenged (for example, alleged duress or misrepresentation)
• A claimant argues that statutory claims were not validly waived

In such cases, the underlying employment claim would still be subject to the usual tribunal limitation period:

• 3 months less one day from the relevant act (e.g., dismissal or discriminatory act)

The settlement agreement does not usually extend or reset this limitation period.

ACAS COT3 Agreements: Different Enforcement Route

Some settlement agreements take the form of a COT3 agreement, which is made through ACAS conciliation.

Key differences include:

• COT3 agreements are legally binding without needing formal contract execution
• They are enforceable through the courts as contractual obligations

If a dispute arises over a COT3 agreement:

• Enforcement is typically through the County Court or High Court
• The limitation period is generally 6 years

When Does Time Start Running?

For settlement agreement disputes, the limitation period usually starts from the date of breach, not the date of signing.

Examples:

• If payment was due on 1 January but not made, time runs from 1 January
• If instalments are missed, each missed payment may create a separate limitation period
• If a continuing obligation is breached, the court may assess when the breach occurred or continued

Invalid Settlement Agreements and Limitation Issues

Sometimes a party seeks to challenge the validity of a settlement agreement rather than enforce it.

Common grounds include:

• Misrepresentation
• Duress or undue pressure
• Lack of proper legal advice
• Failure to comply with statutory requirements

Where a settlement agreement is alleged to be invalid, the underlying employment rights may still be subject to tribunal limitation rules, meaning:

• A claimant may still be out of time for the original employment claim even if the settlement is challenged

This creates a significant legal distinction between:

• Contract enforcement (6 years)
• Employment rights claims (usually 3 months less one day)

Extension of Time and Court Discretion

In civil courts dealing with settlement agreement disputes:

• The 6-year limitation period is strictly applied
• Courts have limited discretion to extend time under exceptional circumstances
• Arguments about delay usually focus on when the breach occurred rather than extending the limitation period itself

In Employment Tribunals, where settlement issues arise indirectly, extension rules are much stricter and rarely applied outside statutory exceptions.

Common Practical Issues in Settlement Agreement Disputes

1. Late or missing payments

The most frequent dispute, usually treated as straightforward breach of contract.

2. Interpretation of clauses

Disputes may arise over confidentiality, references, or bonus entitlements.

3. Tax treatment disagreements

Issues where net payment differs from expected due to deductions.

4. Waiver of claims disputes

Arguments that the agreement does not properly waive statutory claims.

5. Multiple breaches over time

Instalment payments or ongoing obligations can create separate limitation periods.

Consequences of Missing the Limitation Period

If a claim is brought too late:

• The court will usually strike out the claim as time-barred
• Recovery of unpaid sums becomes impossible through legal proceedings
• Negotiation may be the only remaining option
• Employment Tribunal routes may also be unavailable if underlying claims are out of time

Key Takeaways

The limitation period for settlement agreement disputes in England and Wales depends on the legal route taken:

• Most disputes are treated as breach of contract claims
• The limitation period in the civil courts is 6 years from the date of breach
• Employment Tribunals generally do not hear enforcement claims but may consider related employment rights disputes subject to the 3 months less one day rule
• COT3 agreements are also enforceable as contracts, typically subject to the same 6-year limitation period

Understanding whether the issue relates to contract enforcement or underlying employment rights is essential to determining the correct limitation period.
