What it means
The purpose is to catch disagreement early and cheaply. Negotiating parties often think they have agreed a deal when in fact they hold different assumptions about price adjustments, what is included, who carries which risk, or when completion happens.
Writing the headline terms on two or three pages surfaces those differences before either side spends significant money on legal drafting and due diligence. A typical document covers the parties, what is being bought or agreed, the price and how it is structured, key conditions such as financing or regulatory approval, a timetable, exclusivity, confidentiality, who bears costs, and the governing law.
It is written in plain commercial language rather than full contractual drafting, which is exactly what makes it useful to the people actually doing the deal. The binding and non-binding distinction is the part that causes trouble.
Commercial terms are normally expressed as subject to contract and are not enforceable, while confidentiality, exclusivity, cost allocation and dispute provisions usually are. If the document is silent or sloppily drafted, a court may find that the parties intended to be bound, so the status of every clause should be stated explicitly.
Its real influence is psychological rather than legal. Once both sides have signed a heads of agreement, moving away from a term written in it becomes socially and commercially expensive, even where nothing is enforceable.
Experienced negotiators therefore treat it seriously and resist the temptation to leave difficult points vague for later. Exclusivity is often the single most valuable clause for a buyer.
A period of perhaps sixty to ninety days in which the seller cannot negotiate with anyone else justifies spending real money on due diligence, and sellers grant it in exchange for a credible price and timetable. Getting that trade right is usually the main commercial negotiation within the document itself.
In practice
Real-world examples.
Example
A manufacturing group agreeing to buy a competitor signs a two-page heads of agreement setting a headline price, a completion target of ninety days, and a seventy-five day exclusivity period. Due diligence then reveals an unrecorded environmental liability, and because the price was expressed as non-binding and subject to contract, the buyer renegotiates rather than walks.
Example
Two software companies planning a joint product write a heads of agreement covering revenue sharing, who owns the resulting intellectual property and what happens if either party is acquired. The intellectual property discussion takes three weeks and saves a much larger argument eighteen months later.
Example
A landlord and a prospective anchor tenant record heads of terms for a fifteen-year lease, including rent, a rent-free period and responsibility for fitting out. The document runs to four pages and the eventual lease runs to ninety, but the commercial substance was settled in the short one.
Case study
Seen in the real world.
The following is an illustrative and entirely fictional scenario. Redgate Robotics, an invented automation business, agreed in principle to acquire a smaller sensor manufacturer for $8,000,000, with both chief executives shaking hands after a productive afternoon and instructing their lawyers to prepare documents.
Six weeks and a considerable legal bill later it emerged that the buyer had assumed the price was payable in three annual instalments and included the founder staying for two years, while the seller had assumed a single payment at completion and a six-month handover. Neither party had behaved badly; they had simply never written the terms down side by side.
In this illustrative example the deal was rescued by stepping back and preparing a proper heads of agreement: $6,000,000 payable at completion, $2,000,000 as an earnout over two years tied to revenue targets, a twelve-month consultancy for the founder, sixty days of exclusivity, and an explicit statement that only the confidentiality, exclusivity and costs clauses were binding. The transaction completed four months later, and the company adopted a standing rule that no deal above $1,000,000 would go to legal drafting without a signed heads of agreement.
Watch out
Common mistakes.
- Assuming the whole document is non-binding. Confidentiality, exclusivity and costs clauses are usually enforceable, and poorly drafted commercial terms can bind more than intended.
- Leaving contentious points deliberately vague to keep momentum. Ambiguity does not disappear during drafting; it reappears later when positions have hardened and walking away is expensive.
- Treating it as pure formality and signing without legal review. A short document can still create real obligations, particularly around exclusivity and the sharing of costs.
Questions
People also ask.
Is a heads of agreement legally binding?
Generally the commercial terms are not, provided they are clearly marked as subject to contract, while specific clauses such as confidentiality, exclusivity, costs and governing law usually are.
How is it different from a letter of intent or memorandum of understanding?
In practice these terms are largely interchangeable, and the substance of the drafting matters far more than the label at the top of the page.
How long should one be?
Usually two to five pages, because the point is to capture commercial substance quickly; anything much longer is drifting towards being the contract itself.
