Breach of a settlement agreement

What counts as a breach of a settlement agreement

A settlement agreement is a contract that ends a dispute on agreed terms, usually by one side paying money and the other giving up (releasing) its claims in “full and final settlement”. In the UK the label covers several forms: a workplace settlement agreement that waives statutory employment claims under section 203 of the Employment Rights Act 1996; a COT3 recorded through ACAS conciliation; a Tomlin order that stays court proceedings on terms scheduled to the order; and an ordinary commercial or litigation settlement, sometimes executed as a deed. Whatever the form, the terms bind both parties once the agreement is concluded, even though the negotiations that produced it were conducted “without prejudice”.

A breach is any failure to perform an obligation the agreement imposes. Not every breach carries the same consequence. A minor or technical breach, such as a payment arriving a few days late, usually sounds only in damages and does not release the other party from its own duties. A repudiatory breach, meaning a breach that goes to the root of the contract or shows an intention no longer to be bound, may give the innocent party a choice: affirm the agreement and sue on it, or accept the repudiation, treat itself as discharged, and (depending on the drafting) revive the very claim the settlement was meant to end. Whether non-payment of the settlement sum amounts to a repudiation that revives the underlying claim turns heavily on how the release and the payment obligation are worded.

Common ways a settlement agreement is breached

Most disputes about breach fall into a familiar set of scenarios. Knowing the usual failure points helps both when drafting and when deciding whether a breach has actually occurred:

• Non-payment or late payment of the settlement sum, or a missed instalment where payment is staged over time.
• Breach of a confidentiality or non-disclosure clause, for example by disclosing the amount, the terms, or even the existence of the settlement to someone outside the agreed exceptions.
• Breach of a non-derogatory or non-disparagement clause, including negative comments to colleagues, customers, or on social media.
• Failure to provide an agreed reference, or refusing to use the agreed reference wording.
• Reviving, threatening, or issuing a claim that was released, in breach of a “full and final settlement” and any covenant not to sue.
• Breach of agreed undertakings such as returning company property, deleting confidential material, or observing a restrictive covenant.
• Breach of a warranty, for example where a party warranted that it had disclosed all claims, or that it had not already accepted new employment, and the warranty proves false.

Remedies for breach of a settlement agreement

Because a settlement agreement is a contract, the innocent party can draw on the ordinary contractual remedies. The right choice depends on the obligation breached and the loss suffered:

• Debt claim for the agreed sum. Where the breach is simply non-payment of a fixed amount, the innocent party can sue for the debt itself, which is usually more straightforward than proving damages.
• Damages. The court aims to put the innocent party in the position it would have been in had the agreement been performed, subject to the usual rules on causation, remoteness, and mitigation.
• Injunction. For breaches of confidentiality or restrictive covenants, an injunction (including an urgent interim injunction) may restrain a threatened or continuing breach, since damages alone are often an inadequate remedy.
• Specific performance. A discretionary order compelling a party to perform, granted sparingly and rarely for a straightforward payment obligation.
• Clawback or repayment. Many settlements provide that the sum, or part of it, must be repaid if the recipient breaches, for example by disclosing the terms or bringing a released claim. Such clauses are common, but a repayment or liquidated damages figure that is out of all proportion to any legitimate interest risks being struck down as a penalty under the rule confirmed in Cavendish Square Holding BV v Talal El Makdessi [2015].

The innocent party should act consistently with the remedy it wants. Continuing to accept performance while treating the contract as at an end sends mixed signals and can amount to affirmation, so it is worth taking advice before choosing a route.

How to enforce a settlement agreement in the UK

Enforcement is usually a staged process rather than an immediate court claim. Working through it in order keeps costs down and preserves the evidence a court will want to see:

• Identify the exact obligation breached. Read the wording closely, confirm the obligation was owed and unperformed, and check for any dispute resolution or mediation clause that must be followed first.
• Gather evidence. Keep the signed agreement, proof of the breach (missed payment records, the offending post or disclosure), and evidence of any loss.
• Send a letter before claim. Comply with the Practice Direction on Pre-Action Conduct and Protocols: set out the breach, the remedy sought, and a reasonable deadline to put matters right before proceedings.
• Choose the enforcement route. An ordinary breach or debt claim runs in the County Court or, for larger or more complex matters, the High Court, with lower-value money claims capable of being started online [thresholds and allocation. A Tomlin order is enforced by applying to the same court to lift the stay and give effect to the scheduled terms, without issuing a fresh claim. A financial COT3 or a tribunal award can be enforced as a debt in the civil courts, and certain awards and ACAS-conciliated settlements can be pursued through the fast-track enforcement scheme using High Court Enforcement Officers.
• Watch the limitation period. A claim for breach of a simple contract must generally be brought within six years of the breach under the Limitation Act 1980; a longer period applies where the settlement was executed as a deed [deed period.

Enforcing a settlement is often quicker than the dispute it resolved, because liability is already agreed and the argument is usually confined to whether a defined obligation was met. That is exactly why precise drafting pays off.

Drafting to reduce the risk of breach

Most breaches are made easier to prove, and easier to remedy, by clear drafting at the outset. When settling a dispute, check that the agreement contains:

• Clear, dated payment terms, an instalment schedule if relevant, and provision for interest or acceleration of the whole balance if a payment is missed.
• A defined consequence for non-payment, for example making the release conditional on payment being received in cleared funds.
• A confidentiality clause with sensible carve-outs, such as disclosure to a spouse or partner, professional advisers, HMRC, a regulator, or where required by law.
• Mutual, specific non-derogatory obligations rather than a one-sided or vague promise.
• Warranties and, where appropriate, a clawback clause drafted to reflect a genuine legitimate interest so it survives the penalty rule.
• An entire agreement clause and an unambiguous statement of exactly which claims are being released.
• The agreed governing law and jurisdiction, and a decision on whether to execute the document as a deed.
• For employment settlements, confirmation that the conditions in section 203 of the Employment Rights Act 1996 are satisfied, including advice from a relevant independent adviser who is identified and insured.

Getting a breach of a settlement agreement resolved in the UK ultimately comes down to disciplined contract management: knowing what each side promised, tracking the deadlines, and holding the evidence in one place. A CLM platform such as Pactolane keeps every signed settlement in a searchable repository with a full audit trail, and renewal and deadline alerts flag instalment dates and notice windows before they lapse. Its PactAI copilot can extract the payment, confidentiality, and release terms, score the risk of a clause, flag conflicts, and produce a plain-language summary so a reviewer sees what matters faster, while a person still decides how to act. This is general legal information, not legal advice; where the wording, figures, or enforcement route are in doubt, take advice from a qualified solicitor before you act.
