Heads of Terms, Letters of Intent and Memorandums of Understanding

Setting the Foundation for Your Business Deals

Before a full contract is drawn up, businesses often need to record the key points of a deal they’ve agreed in principle. Heads of Terms, Letters of Intent and Memorandums of Understanding all serve this purpose — but it’s vital to understand what they do (and don’t) commit you to, and how to use them properly.

Getting these documents right at the outset can save significant time, money and frustration later on. Getting them wrong can lead to unexpected legal obligations or, conversely, a false sense of security about a deal that isn’t actually binding.

What Are They?

Heads of Terms (HoTs) — Sometimes called Heads of Agreement, these set out the principal terms of a proposed deal. They’re commonly used in property transactions, business sales, and commercial contracts to record what has been agreed before the solicitors start drafting the full agreement.

Letters of Intent (LoIs) — These typically indicate one party’s intention to enter into a contract or proceed with a transaction, often setting out the key terms on which they intend to contract. They’re frequently used in procurement, construction, and corporate transactions.

Memorandums of Understanding (MoUs) — These record a mutual understanding between parties, often in the context of collaborations, partnerships, or public sector arrangements. They’re particularly common where the parties want to set out a framework for working together without creating a full contractual relationship.

Are They Legally Binding?

This is the most important question — and the answer is: it depends.

By default, Heads of Terms, Letters of Intent and Memorandums of Understanding are often (but not always) intended to be non-binding. They record the parties’ intentions and provide a roadmap for drafting the full agreement. However:

• Certain clauses within them can be made binding — for example, confidentiality obligations, exclusivity periods, costs arrangements, and governing law clauses.
• If they are poorly drafted, a court may find that they create binding obligations even if that wasn’t intended.
• If parties start performing based on these documents, binding obligations can arise by conduct.

It’s therefore essential that these documents clearly state which provisions are intended to be binding and which are not.

When Should You Use Them?

These documents are useful when:

• You’ve agreed the key commercial terms of a deal, but the full contract will take time to prepare.
• You want to commit the other party to exclusivity while negotiations continue.
• You need to record what’s been agreed so far to avoid misunderstandings.
• You want to provide comfort or authority to start preliminary work before the full agreement is signed.
• You’re entering a collaboration or partnership and want to establish ground rules without a full contract.
• You need internal or board approval and want to document the proposed terms for consideration.

What Should They Include?

Our Commercial Team will help you prepare a document that covers:

• The parties — Who is involved in the deal.
• The subject matter — What the deal or arrangement is about.
• Key commercial terms — Price, payment, scope, timeline, exclusivity, territory.
• Conditions — Any conditions that must be satisfied before the full agreement is entered into (e.g. due diligence, board approval, financing).
• Binding provisions — Clearly identified clauses that are intended to be legally binding (e.g. confidentiality, exclusivity, costs).
• Non-binding status — A clear statement that the remaining provisions are not intended to create legal obligations.
• Timeframe — A target date for completing the full agreement.
• Costs — Who bears the costs of the transaction if it doesn’t proceed.
• Governing law — Which jurisdiction’s law applies.

Risks of Getting It Wrong

• Creating binding obligations you didn’t intend.
• Having no binding obligations where you needed them (e.g. exclusivity or confidentiality).
• Spending time and money negotiating a full contract only to discover the other party interprets the deal differently.
• Starting work or spending money based on a document that provides no legal protection.
• Losing a deal because the other party didn’t consider the arrangement sufficiently certain to proceed.
