A letter of intent establishes a documented framework for contract negotiation without imposing the full set of legal obligations a signed agreement would carry.

Letters of intent are used across commercial, corporate, and employment contexts, each time serving the same purpose: to put the broad terms of a deal on paper before either party commits to the cost and precision of formal drafting. This article covers the definition, common uses, key components, legal status, and how LOIs connect to the broader contract workflow.

What a Letter of Intent Is Used For

A letter of intent is used when parties want to commit to negotiating on agreed commercial terms before investing in full contract drafting. It prevents misaligned assumptions from derailing a deal later by establishing, in writing, what each party understands the proposed transaction to be before detailed legal work begins.

A letter of intent in a business acquisition sets out the buyer’s proposed purchase price, deal structure, payment terms, timeline, and key conditions before due diligence begins. It signals to the seller that the buyer is serious, aligns both parties on the broad terms of the transaction, and provides the framework against which due diligence findings will be assessed.

In partnership and joint venture negotiations, a letter of intent defines the contribution terms, governance arrangements, decision-making rights, and scope of the proposed relationship before formal drafting begins. In significant vendor or supplier agreements, it captures the commercial structure, pricing approach, and key conditions the final contract will formalise.

Letters of intent also appear in commercial property transactions, where they confirm the principal terms of a lease or purchase before the formal agreement is drafted, and in senior employment arrangements, where they document key offer terms before an employment contract is prepared. A letter of intent may precede any of the types of contracts a business regularly enters into.

Key Components of a Letter of Intent

A letter of intent should include the names of the parties, the proposed deal terms, any binding provisions, and an expiry date. The level of commercial detail varies by context, but all letters of intent must be precise enough on the core terms that both parties share the same understanding of what is being proposed.

In a business acquisition context, the key commercial terms in an LOI include the proposed purchase price and payment structure, the assets or shares being acquired, the conditions the buyer requires to be met before closing, and the timeline within which those conditions must be satisfied. In a partnership LOI, the equivalent terms cover contribution structure, governance rights, exclusivity, and revenue or profit allocation.

Beyond the commercial terms, most letters of intent designate specific provisions as binding: most often confidentiality, exclusivity, and governing law. The mechanism is a specific clause in the document that names each binding provision. Without that clause, the entire document may be treated as non-binding, including obligations both parties intended to enforce.

A well-drafted letter of intent is concise. It captures the essential commercial agreement in plain terms, establishes which provisions bind, sets a realistic timeline, and stops. The contract terms an LOI documents in outline become legally enforceable only once they are incorporated into the formal agreement.

Binding vs. Non-Binding Provisions

A letter of intent is generally not legally binding as a whole, but specific provisions it designates as binding are enforceable. The proposed price, deal structure, and commercial conditions form the non-binding body of the LOI and can be renegotiated or walked away from. The provisions explicitly named as binding cannot be.

The clauses most often designated as binding in an LOI are the confidentiality clause, the exclusivity clause, and the governing law clause. Confidentiality protects sensitive information shared during the negotiation period from being disclosed or used outside the deal context. Exclusivity prevents either party from pursuing a competing transaction while the LOI is in force.

The governing law clause establishes which jurisdiction’s courts and rules apply if a dispute arises from the LOI itself or from the conduct of the negotiations it governs. Designating governing law as binding prevents jurisdictional disputes from arising out of the pre-contract period before the final agreement is executed.

If an LOI does not state clearly which provisions are binding, a court may treat more of the document as enforceable than either party intended. Every letter of intent should contain an explicit clause naming each binding provision and confirming that all other terms carry no legal force, applying the same logic used to structure the essential elements of a contract in a formal agreement.

Conditions Precedent and Expiry

Conditions precedent are events or actions that must occur before the final agreement can be executed: regulatory approval, completion of due diligence, confirmation of financing, or sign-off from a board or investment committee. In a letter of intent, they define what each party must fulfil for the deal to proceed and create a shared checklist both sides can track through the negotiation period.

The conditions precedent in an LOI also allocate responsibility. One condition may require the seller to obtain a specific regulatory clearance; another may require the buyer to secure committed financing within a defined window. Setting these out in the LOI prevents later disputes about whether a required condition was met, or which party was responsible for satisfying it.

An expiry date sets the point at which the LOI lapses if no final agreement is reached. Without one, negotiations can continue indefinitely, consuming legal and management resources with no clear endpoint and no mechanism to force either party to commit or withdraw. A realistic expiry date, calibrated to the genuine complexity of the transaction, protects both sides from open-ended commitment.

Letter of Intent vs. Memorandum of Understanding

The difference between a letter of intent and a memorandum of understanding is primarily one of context and convention: both are pre-contract documents that express intent, and neither is inherently more legally binding than the other. What binds in either document is determined by what the document explicitly designates as enforceable, not by the title it carries.

In M&A, business acquisition, and commercial deal contexts, letter of intent is the standard term. The memorandum of understanding is more common in government agreements, cross-border institutional partnerships, and public sector procurement, where “letter” implies a level of informality that may not suit the parties. In some Commonwealth jurisdictions, the same instrument is referred to as heads of agreement.

The structural difference between the two documents is also largely a matter of convention. A letter of intent is written in letter format, addressed from one party to another, and kept concise. A memorandum of understanding is more often structured as a formal bilateral document with numbered clauses, more closely resembling a contract in presentation, even when its legal status is the same.

The practical rule for choosing between the two is straightforward: use the term that is conventional in the relevant industry and jurisdiction, and ensure that whichever document is used contains an explicit statement of which provisions bind and which do not. A precisely drafted MOU provides more protection than a vaguely drafted LOI, regardless of which label is used.

How to Draft a Letter of Intent

Start with the commercial terms. Before writing any legal language, establish what the deal actually is: the parties, the proposed price or contribution, the payment structure, and the key conditions each side must meet. An LOI that documents the commercial substance clearly produces a faster, cleaner negotiation than one built on legal provisos around terms that are not yet agreed.

State explicitly which provisions are binding. This is the most consequential drafting decision in any letter of intent: a document that leaves binding status ambiguous creates legal exposure for both parties. Every LOI should include a clause naming each binding provision and confirming that all other terms in the document carry no legal force.

Set a realistic expiry date and keep the document short. An LOI that runs to ten or more pages is no longer a pre-contract document: it is a first draft of the formal agreement, bringing the negotiation complexity it was meant to defer. Length in a letter of intent is often a signal that the commercial terms are not yet genuinely agreed.

Once the commercial terms are documented and the LOI is signed, the formal drafting phase begins. Teams working from a contract template library move through this stage faster by applying consistent, pre-approved formats to contract drafting from first draft to executed agreement.

Letters of Intent in the Contract Lifecycle

A letter of intent fits into the pre-sign stage of the contract lifecycle, before formal contract drafting and negotiation begin. It is the first document in the stages of contract lifecycle management, from initial approach through to executed agreement, converting an exploratory conversation into a documented commitment to negotiate on agreed terms.

Most organisations treat the LOI as a standalone document. It gets drafted, signed, and filed in an email thread or shared folder, disconnected from the formal agreement that follows it. When that happens, binding obligations like confidentiality and exclusivity continue running through the negotiation period with no system tracking them, conditions precedent go unmonitored, and the link between the LOI’s agreed terms and the executed contract is lost.

That loss of connection matters more than it appears. When disputes arise during or after a transaction, the letter of intent is often the primary evidence of what the parties originally agreed. If it is stored in a personal email folder or was never formally executed, its evidentiary value is unclear, and it may be effectively inaccessible when it is most needed.

Miramis stores pre-sign documents, including letters of intent, within the same contract repository that holds every version of the formal agreement. Binding obligations, including confidentiality periods, exclusivity windows, and conditions precedent, are tracked as active obligations from the moment the LOI is stored, not managed separately in a spreadsheet or email folder.
