Legal advice and the ACAS route: what has to happen before you can sign

Last reviewed: 8 July 2026

A settlement agreement is not legally binding until you've had independent legal advice on it. Here is exactly who can give that advice, who pays for it, and the ACAS alternative.

A settlement agreement only becomes binding once a specific legal requirement is met, and it’s not optional for either side.

Why the advice requirement exists

A settlement agreement is not legally binding unless you’ve received advice from a relevant independent adviser on its terms and effect, in particular what it means for your ability to bring a tribunal claim. This has to be a qualified solicitor, a certified trade union official, or a certified advice centre worker, and they need to carry professional indemnity insurance covering that advice. This requirement, and the wider standards for how settlement discussions should be conducted, are set out in the Acas Code of Practice on Settlement Agreements.

Skip this step and the agreement doesn’t hold. If your employer later tries to rely on it without you having had that advice, you keep your right to bring the claims it was meant to settle.

Who pays for it

There’s no legal requirement for your employer to pay your legal fees, but it’s standard practice for them to make a contribution, commonly a few hundred pounds, specifically so the agreement is properly advised and therefore enforceable. Ask for it if your employer hasn’t already offered.

The ACAS alternative

A settlement agreement isn’t the only route to a binding exit. ACAS conciliation can produce a COT3 agreement instead, which is also legally binding but doesn’t require you to take independent legal advice first. This is more common where a tribunal claim has already been lodged, or ACAS early conciliation is already underway.

Before you sign anything

Get the offer in writing. Take the time ACAS guidance points to, generally at least 10 calendar days, to get advice and think it through properly. Ask your adviser to check specifically what claims you’d be giving up, not just the headline payment, some settlement agreements are drafted broadly enough to cover claims you don’t yet know you might have.

FAQs

Frequently asked questions

Who can give the independent advice needed to make a settlement agreement binding?

A qualified solicitor, a certified trade union official, or a certified advice centre worker, and they need professional indemnity insurance covering that advice.

Do I have to pay for that advice myself?

There's no legal requirement for your employer to pay, but it's standard practice for them to contribute a few hundred pounds so the agreement is properly advised and enforceable. Ask for it if they haven't offered.

Is a COT3 agreement the same as a settlement agreement?

Both are legally binding, but a COT3 comes through ACAS conciliation and doesn't require you to take independent legal advice first.
