Memorandum of understanding, or agreement

In one line. A memorandum of understanding records what two sides have agreed so far and usually says, somewhere in its own text, how much of itself is meant to bind — which is the sentence the whole document turns on.

An MOU appears at the point where a conversation has gone well enough to be written down but not far enough to be a contract. Both sides want a record. Neither wants to be held to a deal whose details are still missing.

So they write a document that describes an understanding, and then spend a paragraph explaining what the document is.

What an MOU usually holds

A memorandum of understanding is commonly built from the same blocks whatever the subject.

Who is talking. The two organisations, named properly.

What is being contemplated. The joint project, the supply arrangement, the acquisition, the partnership — described in the general terms it is currently understood in.

What each side would do. Contributions, roles, rough responsibilities. Written as intentions rather than obligations.

Timing. How long the understanding runs, and what happens at the end of it — usually either a real agreement or nothing.

Exclusivity. Whether either side may talk to anyone else about the same thing while this is alive.

Confidentiality. What each side may say about the discussions and about what the other has shown them.

Costs. Who pays for their own side of the work meanwhile.

And a paragraph about itself. Which parts are meant to be binding and which are not.

Is a memorandum of understanding binding?

That question has no general answer, and the document usually tries to answer it for itself.

Most MOUs contain a statement along the lines of: this memorandum records intentions and is not intended to create legal obligations, except for the clauses on confidentiality, exclusivity, costs and governing law, which are. That structure is so common it is close to a convention — the commercial terms are held loosely, and the handful of protective clauses are held tightly.

Whether that division works as written is not decided by the label on the front. It depends on the words, on what the two sides then did, and on the law the document names. It is exactly the kind of question a lawyer earns a fee answering, and it is worth asking before signing an MOU for something large.

Where the binding lines hide

They are rarely at the top, and they are rarely under a heading that announces them.

Look for the paragraph near the end that starts with something about status or effect. Look at the confidentiality clause, which is nearly always meant to bind. Look at exclusivity, which is a real obligation with a real cost — agreeing not to speak to anyone else for a period is a commitment however loosely the rest is worded. Look at the costs clause, and at whether either side is committing money.

Then look at the language everywhere else. Documents that mean to bind say shall and will. Documents that do not say intend to, expect to, anticipate, in good faith. A memorandum that says shall throughout its commercial section and then declares itself non-binding at the end is a document at war with itself, and worth raising before it is signed rather than after.

The neighbouring papers do the same job at different temperatures. A letter of intent is usually one-sided in form, sent by one party and countersigned. A term sheet sets out the commercial points of a deal in a short list, and carries the same binding-and-non-binding split.

Why people write one anyway

Because a written understanding does useful work even when most of it does not bind.

It forces both sides to find out whether they actually agree. A great many things that sound settled in a meeting turn out to be two different plans as soon as somebody types them.

It gives everyone something to take back internally — a document a board or a partner can read.

It fixes the sequence. What is agreed now, what is being worked out, what is deferred to the real agreement.

And it puts the protective clauses in place early, which is often the practical reason for the whole exercise: confidentiality and exclusivity are needed during the negotiation, not after it.

An MOU is also a good moment to remember that agreeing and signing are separate acts, and that a document marked as non-binding is still a document with names on it — accepting is not signing covers the distinction, and without prejudice covers the other label people put on paper while things are unsettled.

At the door. contracts.io makes paper, not legal advice. Describe the understanding in your own words and read back a memorandum of understanding, a letter of intent or a term sheet in plain language, with the governing law named from the full list — England and Wales, Delaware, Singapore or wherever the deal will actually live.
