How Long Do I Have to Sign a Settlement Agreement?

No Statutory Time Limit

The law does not impose a minimum or maximum time for signing a settlement agreement. There is no statutory deadline. This means legally, you could theoretically take months to decide whether to sign.

However, in practice, employers often impose deadlines. They want closure and certainty about the employment ending. An unreturned settlement agreement creates uncertainty for business planning and for the employer's management of the departure.

Acas Guidance: 10 Calendar Days

Whilst there is no legal requirement, Acas (Advisory, Conciliation and Arbitration Service) provides guidance on good practice. Acas recommends that employees should have a minimum of 10 calendar days from when a settlement agreement is presented to consider the offer and obtain legal advice.

This Acas guidance is not legally binding, but it represents best practice and is widely recognised in employment disputes. Tribunals may view an unreasonably short deadline unfavourably if a dispute arises.

What Constitutes a Reasonable Timeline?

10 Days or More: Clearly Reasonable

If the employer gives you 10 or more calendar days to review the settlement and obtain legal advice, this is clearly reasonable and in line with Acas guidance. You have adequate time to:

• Arrange and obtain legal advice from a qualified lawyer
• Review the agreement carefully with your lawyer
• Negotiate terms if needed
• Consult with financial or tax advisors if necessary
• Consider the offer carefully and make an informed decision

5-10 Days: Borderline

If the deadline is 5-10 days, this is borderline. It may be achievable if you quickly contact a lawyer and they can prioritise your review, but it is tighter than ideal. You should:

• Contact a lawyer immediately to discuss
• Request an extension if the lawyer needs more time
• Request that the employer agrees a longer period if 10 days is not feasible
• Document your request for extension in writing (email)

Less Than 5 Days: Unreasonable

A deadline of less than 5 days is generally considered unreasonable. It may be difficult or impossible to:

• Contact a lawyer and arrange an appointment
• For the lawyer to review the agreement thoroughly
• For the lawyer to provide formal legal advice as required by Section 203 ERA 1996
• For any negotiation if needed
• For you to make a truly informed decision

If facing a deadline of less than 5 days, you should:

• Contact a lawyer immediately to explain the timeline
• Request a written extension from the employer
• Explain that Section 203 ERA 1996 requires legal advice before signing
• Do not sign without proper legal advice regardless of pressure

How to Count the Timeline

Understanding how to count calendar days is important:

Calendar Days vs. Working Days

Acas guidance refers to "calendar days," not working days. This means:

• Calendar days include weekends and bank holidays
• 10 calendar days starting Monday = Thursday of the following week
• Working days are shorter and less generous (approximately 7 working days per 10 calendar days)

If your employer specifies a deadline in "working days," ask for clarification or for it to be converted to calendar days. Calendar days are more employee-friendly.

Starting Point

The countdown typically starts from the date you receive the settlement agreement. If the agreement is emailed to you on Monday morning, Monday is typically day 1 (or sometimes day 0, with the deadline running from the next day).

If unsure about how the deadline is calculated, ask your employer's HR department in writing for confirmation of the exact deadline.

The Final Day

Clarify whether the deadline is:

• Close of business on the final day (typically 17:00 or 17:30)
• Midnight at the end of the final day
• First thing the next morning

Having the deadline extend to close of business on the final day (rather than midnight) gives you a few extra working hours if needed.

Negotiating an Extension

If the deadline given is unreasonably short, you can and should request an extension. How to do this:

Request in Writing

Always request an extension in writing (email). This creates a record. Your request might read:

"I have received the settlement agreement and appreciate the offer. I require additional time to obtain independent legal advice as required by Section 203 of the Employment Rights Act 1996. Please can you extend the deadline to [date] to allow me to obtain proper legal advice and respond."

Give Reasons

Explain why the current deadline is insufficient:

• You need time to contact and brief a lawyer
• Your lawyer needs time to review the agreement
• You need time for legal advice to be provided (in writing)
• You may need to consult with tax or financial advisors
• Section 203 ERA 1996 requires independent legal advice before signing

Propose a New Deadline

Rather than simply asking for more time, propose a specific new deadline. For example:

"I would appreciate a deadline of 21 days from receipt of the agreement to allow proper time for legal advice and consideration."

A reasonable request for an extension is usually granted. Employers know that rushing you into signing without proper legal advice is not in their interests—the agreement could be challenged as invalid if legal requirements are not met.

What If the Employer Refuses?

If your employer refuses to extend the deadline to a reasonable period, this raises concerns:

• They may be trying to pressure you into signing without proper advice
• This may suggest the agreement terms are less favourable than they appear
• They may be aware of legal issues they don't want investigated
• A tribunal might later view such pressure unfavourably

Do not allow pressure to force you into signing without proper legal advice. If the employer will not allow reasonable time, contact a lawyer immediately to discuss your options.

What Happens If You Miss the Deadline?

The consequences of missing a deadline depend on the circumstances:

The Agreement Is Not Automatically Invalid

Missing a deadline does not automatically make the agreement void. A deadline is a condition set by the employer, not a legal requirement. However:

• The employer may withdraw the settlement offer if the deadline passes
• The employer may argue the agreement is no longer binding if you did not sign by the deadline
• The employer may offer different or less favourable terms if you sign later

If You Miss the Deadline and the Employer Withdraws

If the deadline passes and the employer formally withdraws the settlement offer, you are back to the original position:

• You are still employed (unless dismissed)
• You can pursue tribunal claims (if you have grounds)
• The employer may proceed with formal dismissal or disciplinary procedures
• You may be dismissed for reasons stated in the settlement offer process

This is why it is important not to deliberately miss deadlines. If you need more time, request an extension rather than ignoring the deadline.

If You Sign After the Deadline

If you sign after the deadline, the employer may:

• Accept the late signature and treat the agreement as valid
• Refuse to accept the signature and withdraw the offer
• Accept the signature but argue that the deadline condition was not met

Whether a late signature is binding depends on the agreement terms and the employer's conduct. Some agreements specify that signing is conditional on the deadline being met; others are more flexible.

Special Circumstances Affecting Timeline

If You Are Off Work or On Leave

If you are on holiday, sick leave, or otherwise unable to access the settlement agreement promptly, the deadline may be unfair. You should:

• Notify the employer of your absence and inability to review documents
• Request the deadline be extended until you return to work
• Request the timeline be calculated from when you return and have access

It would be unreasonable for an employer to set a deadline while you are on approved leave and unable to respond.

If You Are Unwell

If you are seriously ill or incapacitated, you may not be able to review the agreement or obtain legal advice within a standard timeline. You should:

• Notify the employer of your health situation
• Request the deadline be extended until you are well enough to consider the agreement properly
• Consider whether now is the right time to make this decision

If You Need to Coordinate with Multiple Advisors

If your settlement involves complex tax or pension issues, you may need to consult multiple advisors (legal, tax, and pension specialists). You should request adequate time for this:

• Request 3-4 weeks for complex settlements involving tax and pensions
• Request even longer (4-6 weeks) if pension issues are significant
• Explain that proper advice is in both parties' interests

Summary: Timeline Best Practice

• There is no legal minimum time to sign
• Acas recommends minimum 10 calendar days
• 10+ days is clearly reasonable; less than 5 days is unreasonable
• Request an extension in writing if the deadline is too short
• Explain that Section 203 ERA 1996 requires independent legal advice
• Do not sign without proper legal advice regardless of deadline pressure
• If the deadline passes, the employer may withdraw the offer
• For complex settlements, request 3-4 weeks minimum
• Missing a deadline may result in loss of the settlement offer
• Always get written confirmation of the exact deadline and what it means

The key principle is that you must have adequate time to obtain proper independent legal advice before signing. If you are denied reasonable time, contact a lawyer to discuss your options. A good lawyer can often negotiate a reasonable extension from the employer.
