Settlement Agreements vs ACAS Early Conciliation

You've been offered a settlement agreement. But before you sign, someone mentions ACAS. Or your employer suggests "early conciliation." You're confused. Are these the same thing? Do you need both? How do they relate? This guide clears up the confusion.

What Is ACAS Early Conciliation?

ACAS (the Advisory, Conciliation and Arbitration Service) is a statutory body in the UK that helps resolve workplace disputes. Early conciliation is a mandatory step that must be completed before you can bring most employment tribunal claims.

Here's how it works: If you believe your employer has breached an employment right (unfair dismissal, discrimination, breach of contract, etc.), you must contact ACAS before filing a tribunal claim. ACAS will try to help you and your employer reach an agreement without going to tribunal. This process is usually done by phone or email.

The entire early conciliation process is free and typically takes 4 weeks. If you and your employer reach an agreement during early conciliation, ACAS will issue a document called a COT3 (Conciliation Agreement). This makes the settlement legally binding. If you don't reach agreement, ACAS issues a certificate allowing you to proceed to tribunal.

What Is a COT3?

A COT3 is the formal agreement issued by ACAS when a settlement is reached during early conciliation. It's a statutory form that, once signed, becomes a binding contract. You can't go back to tribunal to pursue your claim if you've signed a COT3 agreeing to settle.

Key points about COT3s:

• They must be issued by ACAS (not by the employer or solicitors directly)
• They have statutory force and are enforceable as contracts
• They typically include a payment amount and are final
• You can still be represented by a solicitor during ACAS conciliation
• Legal advice is advisable before signing a COT3

What Is a Settlement Agreement?

A settlement agreement (also called a compromise agreement) is a private contract between you and your employer. It's not issued by ACAS; it's drafted by solicitors or HR personnel. It serves the same basic purpose as a COT3—to settle a dispute and prevent tribunal proceedings—but it's a different document created outside the ACAS framework.

Settlement agreements typically include:

• A payment amount (often called the "severance" or "ex-gratia payment")
• Warranties and representations from both parties
• A broad release clause (you waive all claims)
• Confidentiality and non-disclosure clauses
• References and post-employment obligations
• Details about continuing benefits or pension

Key Differences Between COT3 and Settlement Agreements

Who issues it?

• COT3: ACAS (a statutory body)
• Settlement agreement: Employer and employee (private parties)

When is it used?

• COT3: During the ACAS early conciliation process (after a claim would be filed)
• Settlement agreement: Can be used at any time, often before a claim is made

Legal force?

• COT3: Statutory legal force under section 203(2)(f) ERA 1996
• Settlement agreement: Contractual force (depends on valid legal representation and consideration)

Legal representation?

• COT3: Optional (ACAS can help you understand the agreement)
• Settlement agreement: Mandatory (you must have legal advice from a solicitor—this is a legal requirement for the agreement to be valid)

When Is Each Used?

Settlement agreements are typically offered by employers before an employee makes a tribunal claim. The employer wants to settle the dispute quickly and avoid tribunal altogether. This is the most common scenario.

You might be offered a settlement agreement if:

• You're being made redundant
• There are performance issues (but the employer doesn't want to go through formal dismissal)
• There's a personality clash or working relationship breakdown
• You've raised a grievance or discrimination claim
• The employer wants to "part on good terms"

COT3 agreements are typically used when an employee has already filed a tribunal claim (or told ACAS they're about to). At that point, ACAS early conciliation is mandatory. If settlement is reached, ACAS issues a COT3.

Advantages and Disadvantages

Settlement Agreements

Advantages:

• Faster—no mandatory ACAS process (though early conciliation has a 4-week window)
• More flexible—terms can be tailored to both parties' needs
• Proactive—you resolve the dispute before a claim is filed
• Often accompanied by references or continued benefits

Disadvantages:

• You must have legal advice (which costs money, though sometimes the employer pays)
• You're releasing all claims, even ones you haven't thought of
• The employer has control over the initial offer

COT3 Agreements (via ACAS)

Advantages:

• Free ACAS support and negotiation
• Neutral third party (ACAS) helping you both reach agreement
• Statutory force (clear legal standing)
• Time-limited—4-week window focuses minds

Disadvantages:

• Only available if a claim would be filed (or has been filed)
• Limited flexibility in the agreement format
• You've already filed a tribunal claim (more confrontational)
• ACAS conciliator has some control over the process

Can You Do Both?

This is an important point: If you're offered a settlement agreement by your employer, you don't have to go through ACAS early conciliation unless you file a tribunal claim. The settlement agreement is a valid way to settle a dispute without ACAS involvement.

However, if you file a tribunal claim, ACAS early conciliation becomes mandatory. At that point, if you reach a settlement, it will be documented in a COT3, not a settlement agreement.

In practical terms: If your employer offers you a settlement agreement, consider it carefully. If you agree, get legal advice, and sign. You won't need ACAS. If you disagree and file a tribunal claim, then ACAS comes into play.

What Your Solicitor Should Advise

If you're offered a settlement agreement or if you're in ACAS early conciliation with a COT3 being drafted, your solicitor should:

• Explain your potential tribunal claims and their value
• Review the payment offer and whether it's fair
• Explain what claims you're releasing
• Check tax implications of the payment
• Ensure you understand the release clause
• Advise on confidentiality and non-disparagement terms
• Negotiate changes if needed

Key Takeaways

• ACAS early conciliation is a mandatory step before filing a tribunal claim
• A COT3 is a settlement agreement issued by ACAS during early conciliation
• Settlement agreements are private contracts used to settle disputes outside the ACAS framework
• Settlement agreements require legal representation (by law); COT3s don't
• Settlement agreements are typically offered before a tribunal claim is filed
• COT3s are used after a tribunal claim is filed or about to be filed
• Both are legally binding and prevent you from pursuing further claims
• Always get solicitor advice before signing either agreement
