MOU Review Checklist: What to Check Before You Sign

If you need a memorandum of understanding review checklist for UK businesses, this page gives you exactly that — no padding. An MOU sits in an awkward legal space: it looks informal, but the wrong wording can create binding obligations you didn't intend. UK courts have found MOUs enforceable where the language was sufficiently certain and the parties clearly intended to be bound. That means you can't just skim it and sign. This checklist covers what every UK founder or business owner should verify before committing: whether the document is actually non-binding, what confidentiality obligations it creates, how disputes are handled, and which clauses signal you need a solicitor rather than a quick read-through. Atornee helps you work through these checks systematically, flags the language that matters, and tells you honestly when the document has moved beyond what an AI tool should handle alone. Use this as your starting point before any partnership, joint venture, or commercial negotiation in the UK.

Why this matters

Most founders treat an MOU as a handshake on paper — low stakes, easy to sign. That assumption causes real problems. An MOU with vague exclusivity language can lock you out of other deals. One with no clear termination clause can leave you in limbo for months. And if confidential information is shared under an MOU without proper protection, you may have no recourse when the deal falls apart. The pain here is specific: you've been handed a document that looks simple, you don't want to spend £500 on a solicitor to review it, but you also can't afford to sign something that quietly commits you to terms you haven't understood.

The Atornee approach

Atornee doesn't replace a solicitor for complex MOUs — it tells you whether you need one. Upload your MOU and Atornee works through the document clause by clause: checking whether binding language has crept in, flagging missing provisions like governing law or dispute resolution, and identifying confidentiality gaps. It gives you a plain-English summary of what the document actually says, not what you assumed it said. For straightforward MOUs between UK parties, that's often enough. For anything involving IP assignment, exclusivity, or significant financial commitments, Atornee will tell you directly to escalate. That honesty is the point.

What you get

A clause-by-clause breakdown of your MOU flagging binding vs non-binding language under UK law
Identification of missing must-have provisions: governing law, termination, confidentiality, and dispute resolution
Plain-English explanation of any exclusivity, IP, or financial commitment language buried in the document
A clear escalation signal when the MOU complexity warrants a qualified UK solicitor
A reusable checklist framework you can apply to every MOU your business receives going forward

Before you sign checklist

1
1. Confirm whether the MOU explicitly states it is non-binding — look for phrases like 'subject to contract' or 'not legally binding'; absence of these is a red flag
2
2. Check for a governing law clause — it should specify England and Wales, Scotland, or Northern Ireland depending on your jurisdiction
3
3. Review any confidentiality provisions — if sensitive information is being shared, a standalone NDA may be safer than relying on MOU confidentiality language
4
4. Identify any exclusivity or lock-out clauses — these can be binding even in an otherwise non-binding MOU under UK case law
5
5. Verify there is a clear termination mechanism — how either party exits the MOU and what happens to shared information afterwards
6
6. Check for dispute resolution provisions — absence of these means default to UK courts, which may not suit both parties
7
7. Upload the document to Atornee for a structured review before you respond to the other party or request any changes

FAQ

Is a memorandum of understanding legally binding in the UK?

It depends on the language. UK courts look at whether the parties intended to create legal relations and whether the terms are sufficiently certain. An MOU labelled 'non-binding' can still contain binding clauses — particularly around confidentiality and exclusivity. Never assume the label tells the whole story.

What should always be included in an MOU in the UK?

At minimum: a clear statement of whether the document is binding or non-binding, the parties' full legal names, the purpose and scope of the arrangement, a governing law clause specifying the relevant UK jurisdiction, a termination provision, and any confidentiality obligations. Missing any of these creates ambiguity that can be costly to resolve.

What are the biggest red flags in an MOU?

Watch for: exclusivity language without a defined time limit, vague IP ownership provisions, no termination clause, missing governing law, confidentiality obligations that are broader than you realised, and any language that says the parties 'agree to' specific actions rather than 'intend to explore'. That last one can tip a non-binding document into a binding one.

Do I need a solicitor to review an MOU?

Not always. A straightforward MOU between two UK businesses with no exclusivity, no IP transfer, and no significant financial commitment is often reviewable without a solicitor if you know what to look for. But if the MOU involves exclusivity, IP rights, significant commercial commitments, or cross-border parties, get a solicitor involved. Atornee will flag which category your document falls into.

Can an MOU be used instead of a contract in the UK?

No. An MOU is typically used to record intent before a formal contract is drafted. It should not substitute for a contract where real obligations, money, or IP are involved. If the deal is real, the contract needs to be real too. An MOU that tries to do the work of a contract usually does it badly.

How long does an MOU last in the UK?

Only as long as the document specifies — which is why a termination clause matters. If there is no end date or exit mechanism, the MOU can technically persist indefinitely, leaving both parties in an undefined arrangement. Always check for a duration clause or a right to terminate on notice.
