A Memorandum of Understanding (MOU) — also known as a heads of terms, letter of intent, or framework agreement — is a document used in England and Wales to record the mutual intentions and general framework of a proposed collaboration, partnership, or business arrangement between two or more parties before a formal legally binding agreement is executed.

Under English law, an MOU is generally not legally binding as a whole. The requirements for a binding contract — offer, acceptance, consideration, and certainty of terms — are often deliberately absent in an MOU, which is designed to capture intentions rather than firm commitments. However, English courts have consistently held that individual clauses within an MOU — most notably confidentiality and exclusivity clauses — can be made expressly binding even within an otherwise non-binding document, provided they are drafted with sufficient precision and are supported by consideration.

The landmark House of Lords decision in Walford v Miles [1992] 2 AC 128 is particularly important for understanding the status of MOUs under English law. The court held that English law does not recognise a general duty to negotiate in good faith, meaning that a party who signs an MOU cannot generally sue the other party for withdrawing from negotiations or failing to proceed to a formal agreement. This makes the careful drafting of any binding provisions within an MOU — particularly exclusivity and confidentiality clauses — all the more important.

MOUs are widely used across commercial, public sector, academic, and charitable contexts in England and Wales. They serve as a practical tool for structuring the early stages of a relationship, aligning the parties’ expectations, and providing a reference point for subsequent formal negotiations. Our UK MOU template is drafted in accordance with English law and includes optional binding confidentiality and exclusivity clauses.

A Memorandum of Understanding is appropriate in a wide range of commercial and institutional situations in England and Wales where two or more parties wish to record their mutual intentions before entering into a formal binding agreement.

Common situations where a UK MOU is used include: the early stages of a joint venture or strategic partnership negotiation, where the parties wish to signal commitment and establish a framework for discussions before the detailed terms are agreed; university and research institution collaborations, where formal procurement or governance processes prevent the early execution of binding agreements; public sector partnerships, where government bodies and private sector organisations wish to record a shared commitment to a project or initiative; mergers and acquisitions, where a heads of terms or MOU is used to record the key commercial terms of a proposed transaction while due diligence and legal documentation are completed; technology licensing and commercialisation, where the parties wish to explore the terms of a potential licence before committing to a formal licence agreement; and international business relationships, where an MOU provides a culturally familiar framework for beginning a commercial relationship before formal legal agreements are negotiated.

An MOU is also used in situations where the parties wish to begin working together in a preliminary way — for example, sharing information, conducting feasibility studies, or running pilot programmes — before the terms of the formal relationship are finalised. In these cases, the binding confidentiality clause within the MOU is particularly important, as it protects any information exchanged during the preliminary phase.

A well-drafted Memorandum of Understanding for use in England and Wales should contain several key provisions that collectively establish the framework for the proposed collaboration and protect the parties during the preliminary phase.

The statement of purpose is the foundation of the MOU: it clearly describes the nature of the proposed collaboration or arrangement, the goals the parties are seeking to achieve, and the general timeframe. Being specific about the purpose reduces the risk of misunderstanding and provides a clear reference point if the parties later disagree about the scope of the collaboration.

The binding status clause is one of the most important provisions in a UK MOU. It must clearly state whether the MOU as a whole is intended to be legally binding or non-binding. Using clear language such as “this MOU is non-binding and constitutes a statement of intent only” is essential to avoid inadvertently creating a binding contract. At the same time, the MOU should expressly identify any clauses that are intended to be legally binding — particularly confidentiality and exclusivity clauses.

The no-obligation-to-proceed clause reflects the principle in Walford v Miles [1992] and makes clear that neither party is obliged to negotiate or enter into any formal agreement, and that either party may withdraw from discussions without liability. This clause protects both parties from claims of breach of a duty to negotiate in good faith.

The confidentiality clause is a key binding provision in most MOUs: it protects information exchanged during the preliminary phase and survives the expiry or termination of the MOU. The exclusivity clause — where included — provides a lock-out period during which neither party will negotiate with third parties, giving each party comfort that its investment of time and resources in the collaboration is protected.

The intellectual property clause is particularly important in research, technology, and creative collaborations: it establishes the general principle that each party retains ownership of its own pre-existing IP and that jointly created IP will be the subject of a separate agreement.

The governing law and jurisdiction clause specifying England and Wales, the exclusion of third-party rights under the Contracts (Rights of Third Parties) Act 1999, and the entire understanding clause are standard provisions that should be included in any properly drafted UK MOU.
