Cooling Off Periods and Settlement Agreements: Can You Change Your Mind After Signing?

If you have just signed a settlement agreement — or you are being asked to sign one — and you are now having second thoughts, this guide is for you. Below, we explain the legal position clearly, and set out what protections exist for employees and when they apply.


The Short Answer: There Is No Automatic Cooling Off Period

Under English and Welsh employment law, there is no statutory cooling off period for settlement agreements. Once a settlement agreement has been signed and dated by both parties — and your solicitor has signed the accompanying legal adviser’s certificate — the agreement is a legally binding contract. At that point, neither you nor your employer can simply walk away from it.

This is a significant point that surprises many employees. Consumer contracts, for example, often carry a 14-day right of withdrawal. Settlement agreements do not carry an equivalent right. They are commercial contracts, and once concluded, they bind both sides.


Why the Moment of Signing Matters So Much

The binding nature of a settlement agreement is tied to the moment it is properly executed. For a settlement agreement to be valid and legally effective in waiving your employment law claims, it must meet the conditions set out in section 203 of the Employment Rights Act 1996 (and equivalent provisions in other employment statutes, such as section 147 of the Equality Act 2010). These conditions include:

  • The agreement must be in writing
  • It must relate to a specific complaint or proceedings
  • You must have received advice from a relevant independent adviser (such as a solicitor) about the terms and effect of the agreement
  • The adviser must be covered by professional indemnity insurance
  • The agreement must identify the adviser and confirm that these conditions have been met

Once all of these requirements are satisfied and the agreement is signed and dated, it is complete. The act of signing is not a step towards something final — it is the final step.


What About the Period Before Signing?

The critical window for employees is before you sign. This is where your ability to reflect, negotiate, and — if you choose — walk away, is fully preserved.

Your employer must give you reasonable time to consider the offer. The Acas Code of Practice on Settlement Agreements states that employees should be given a minimum of 10 calendar days to consider the proposed terms of a settlement agreement and take independent advice, unless both parties agree to a shorter period. This is not just good practice — it is the standard against which employer conduct will be measured.

During this period, you are under no obligation whatsoever to sign. You can:

  • Take legal advice — which you are required to do in any event for the agreement to be valid (see our main settlement agreement guide)
  • Ask your solicitor to negotiate improved terms on your behalf
  • Simply decide not to proceed and decline the agreement

If you are being pressured to sign quickly, without adequate time to reflect and seek advice, this is something your solicitor should raise directly with your employer.


Can the Agreement Be Undone After Signing? In Very Limited Circumstances

Whilst there is no cooling off period as such, there are narrow legal circumstances in which a signed settlement agreement might be challenged or set aside. These are exceptional situations and not a route to simply changing your mind, but they include:

Misrepresentation. If your employer made a false statement of fact that induced you to sign the agreement, you may have grounds to rescind it. This is a high legal bar and requires demonstrating that the misrepresentation was material to your decision.

Duress or undue influence. If you were pressured into signing in circumstances that the law regards as improper — for example, signing under extreme coercion or without any meaningful opportunity to take advice — a court could potentially find the agreement was not freely entered into.

Failure to meet the statutory conditions. If the agreement does not comply with the formal requirements under the Employment Rights Act 1996, it may not validly waive your statutory claims, even if it is signed. For example, if your adviser was not appropriately qualified, or the certificate was defective, the waiver of claims may not be effective. In practice this is rare, but it is worth your solicitor checking carefully.

These scenarios are uncommon and fact-specific. If you believe any of them apply to your situation, you should seek urgent legal advice.


What If I Signed But My Employer Has Not Yet Countersigned?

A settlement agreement is typically only fully concluded once both parties have signed and the document is dated. If you have signed but your employer has not yet done so, the agreement may not yet be complete. The position will depend on the precise terms and the sequence of events. Again, this is a situation requiring prompt legal advice, as the window may be short.


Practical Steps If You Are Having Doubts

If you are facing a settlement agreement and feeling uncertain, here is what we would recommend:

  1. Do not sign under pressure. You are entitled to the full period to consider the offer. Use it.
  2. Get proper legal advice. This is a legal requirement, not just a suggestion. A specialist solicitor will help you understand what you are giving up, and whether the offer is fair — see our settlement agreement calculator for an initial sense of value.
  3. Understand what you are waiving. Settlement agreements typically require you to waive claims including unfair dismissal, discrimination, and other statutory rights. Our guides on unfair redundancy and confidentiality obligations explain key elements in more detail.
  4. Ask questions. If something in the agreement is unclear — including the tax treatment of your payments or the reference your employer has agreed to provide — your solicitor is there to explain it to you.
  5. Negotiate if necessary. Signing is not inevitable. If the terms are not right, your solicitor can go back to your employer before you commit.

A Note on Without Prejudice Conversations

Settlement agreements are often offered following a without prejudice conversation — sometimes called a protected conversation. The fact that these conversations are legally protected does not mean you are under any obligation to accept what is proposed in them. The offer remains just that: an offer, until you sign.
