Heads of Terms for Australian Businesses: Are They Binding?

You have agreed on the big commercial points, the deal is moving quickly, and someone sends through a short document called heads of terms. This is where many Australian businesses get caught. A founder signs thinking it is only a discussion paper, then finds parts of it may be enforceable. Another business spends money on setup before a full contract is signed, only to discover key issues were never locked in. Others use vague wording like “subject to contract” without checking whether confidentiality, exclusivity or break fees still bind them.

Heads of terms can be useful, but only if everyone is clear on what they do and do not commit the parties to. The real question is not just whether the document is labelled “heads of terms”. It is whether the wording, the conduct of the parties, and the commercial context show an intention to create legal obligations.

This guide explains what heads of terms means for Australian businesses, when it may be binding, what legal issues to check before you sign, and the common mistakes that create expensive disputes later.

Overview

Heads of terms is usually a preliminary document that records the main commercial points of a proposed deal before the full agreement is prepared. In Australia, some or all of it can be legally binding if the drafting shows the parties intended that result, even where they expected a longer contract to follow.

The main risk is assuming the title decides the outcome. Courts look at substance, not just labels, so a short document can still create enforceable obligations if its wording is sufficiently clear and final.

• Whether the document says it is binding, non-binding, or partly binding
• Whether key clauses such as confidentiality, exclusivity, deposits, costs, or dispute processes are intended to apply immediately
• Whether the commercial terms are clear enough to be enforced
• Whether the document says the deal is subject to a formal contract, board approval, finance, due diligence, or landlord consent
• Whether your team might start acting as though the deal is final before the long-form contract is signed
• Whether you are relying on verbal promises that are not written into the heads of terms

What Heads of Terms Means For Australian Businesses

Heads of terms is a negotiation document, but it can also be a legal document. Its effect depends on what it says and what the parties intended when they signed it.

Australian businesses use heads of terms in all kinds of commercial situations, including leases, supply arrangements, service deals, investment discussions, asset sales, joint ventures and distribution arrangements. It is often used when the parties have agreed on the main points and want a short record before lawyers handle the contract drafting for the full agreement.

The document may also be called a term sheet, memorandum of understanding, letter of intent or deal summary. Different labels are used in practice, but the same legal issue comes up each time: did the parties mean to be legally bound now, later, or only on certain points?

Are heads of terms legally binding in Australia?

Yes, heads of terms can be legally binding in Australia, but not always. Some documents are entirely non-binding. Some are fully binding. Many are partly binding, where certain clauses apply immediately and the rest are only a framework for further negotiation.

This is where founders often get caught. A business owner may sign because the document looks short and informal, but the draft includes a binding exclusivity period, a confidentiality obligation, a promise to negotiate in good faith, or a requirement to pay each side’s costs in certain circumstances.

On the other hand, a vague heads of terms may not be enforceable at all if essential terms are missing or the wording shows the parties did not intend legal commitment until a formal agreement was signed.

What makes a heads of terms binding?

The key issue is intention. Courts generally look at the language used, the certainty of the terms, and the surrounding circumstances.

Factors that may point toward a binding outcome include:

• Clear language such as “the parties agree” or “the parties will”
• A statement that all or part of the document is legally binding
• Detailed commercial terms that leave little to negotiate
• Conduct showing both parties treated the deal as final
• Immediate obligations such as payment of a deposit, exclusive dealing, or release of confidential information

Factors that may point away from a binding outcome include:

• Express wording that the document is non-binding
• A statement that the deal is subject to a formal contract
• Major issues still left open for future agreement
• Conditions that have not yet been satisfied, such as due diligence or board approval
• Language showing the document is only a basis for further negotiation

What does “subject to contract” really mean?

“Subject to contract” often helps show the parties do not intend to be bound on the main deal until a formal agreement is signed. But it is not a magic phrase.

If the document also says certain clauses are binding now, those clauses may still be enforceable. If the parties then behave as if the deal is already on foot, the position can become messy. The wording has to be consistent all the way through.

For example, a supplier and retailer may sign heads of terms for a distribution deal that is stated to be non-binding except for confidentiality and exclusivity. If the supplier then begins manufacturing custom stock before the long-form agreement is signed, a dispute can arise over who bears the risk if negotiations later fall over.

Why businesses use heads of terms

Heads of terms can save time and reduce negotiation costs when used properly. They help the parties test whether they are commercially aligned before paying for a full contract.

They are often useful where the deal has several moving parts, such as:

• Price or payment structure
• Term and renewal rights
• Territory or exclusivity
• Key deliverables
• Transition arrangements
• Due diligence or approval steps

They can also focus negotiations by surfacing the issues that matter most before you sign a contract and before you spend money on setup, advisers, stock, fitout or recruitment.

Legal Issues To Check Before You Sign

You should treat heads of terms as a legal risk document, not just a deal summary. Before you sign, make sure the drafting clearly matches what you actually want to happen now and later.

1. Is it binding, non-binding, or mixed?

The first question is simple: what parts are supposed to bind the parties immediately? That should be stated clearly, not left to implication.

A common approach is to make the commercial framework non-binding, while specific clauses are expressly binding. Those binding clauses often include:

• Confidentiality
• Exclusivity or no-shop obligations
• Costs and expenses
• Governing law and dispute process
• Return or destruction of confidential materials
• Break fees or deposits, where appropriate

If you do not want legal commitment yet, the document should say so in plain English. If you do want some protections now, those clauses should be carved out and drafted carefully.

2. Are the key commercial terms clear enough?

A document is more likely to create trouble where the business points are half-finished. Unclear language invites disputes about what was actually agreed.

Before you sign, check whether the heads of terms properly identifies:

• The parties involved, including the correct company entity
• The goods, services, assets, premises or rights covered by the deal
• The price, fees, deposit or payment method
• The timeline for signing the long-form agreement
• Any milestones, handover steps, or conditions
• What happens if negotiations end

If a critical point is still under discussion, say that clearly rather than pretending it is settled.

3. Are there conditions that must be met first?

Many heads of terms are meant to keep the deal conditional. If so, the conditions need to be stated with enough precision to be useful.

Common conditions include:

• Satisfactory due diligence
• Board or investor approval
• Finance approval
• Landlord consent
• Regulatory or third-party consent
• Agreement on a formal contract in an approved form

Founders often assume these are implied. They are not. If you need an approval before the deal is final, it should be written in.

4. What happens during any exclusivity period?

Exclusivity can be one of the most commercially significant parts of heads of terms. If you agree not to negotiate with anyone else for a set period, that can affect your leverage and your timing.

Before you accept the other party's standard terms, check:

• How long the exclusivity period lasts
• Whether it automatically ends on a trigger date
• What information you must provide during that period
• Whether the other party must actively progress the deal
• What remedies apply if either side breaches exclusivity

An open-ended exclusivity clause can leave a business stuck in limbo while opportunities with other counterparties disappear.

5. Are you promising too much before due diligence is complete?

Heads of terms should not force you to commit beyond what you have properly checked. This is especially relevant in acquisitions, supply arrangements, technology deals and leases.

Examples of risk points include:

• Agreeing volumes or service levels before operational review
• Committing to fitout or capital expenditure before lease terms are final
• Accepting warranties about assets before inspection
• Agreeing unrealistic completion dates
• Promising exclusivity before internal approvals are secured

If the commercial assumptions are still being tested, the drafting should preserve flexibility.

6. Does the heads of terms line up with the future contract?

A mismatch between the heads of terms and the final contract creates friction fast. The more detail you include early, the more likely someone later says the formal agreement must match it exactly.

That is not always bad, but you should know the trade-off. A detailed heads of terms can narrow disputes and speed up drafting. It can also harden positions and create arguments if the long-form contract introduces different risk allocation, liability caps, termination rights or intellectual property provisions.

Make sure your team understands which points are genuinely agreed and which are still open for legal review and drafting.

Common Mistakes With Heads of Terms

The biggest mistake is assuming a short pre-contract document cannot hurt you. Most problems come from unclear drafting, rushed signing, or acting as if the deal is final too early.

Signing without checking the binding clauses

Many businesses skim the headline deal terms and overlook the legal mechanics at the back of the document. Confidentiality, exclusivity, costs and dispute clauses are often the parts that matter most if the deal falls over.

A founder may believe the whole document is non-binding because the cover page says so, but a later clause may carve out immediate obligations. If those obligations are breached, the label on page one will not help much.

Relying on verbal promises

Verbal statements made during negotiation often disappear when the heads of terms is circulated. If you are relying on a promise about timing, pricing, exclusivity scope, minimum order levels, fitout contributions or post-signing support, put it in writing.

This matters before you rely on a verbal promise and before you spend money on setup. If the point is commercially important, it belongs in the document or it should be clearly marked as still under negotiation.

Leaving essential terms vague

Vague heads of terms can create false confidence. The parties think they have a deal, but they have only agreed on broad intent.

Common vague areas include:

• How fees will be calculated
• When payment is due
• What counts as completion
• Who owns intellectual property created during the project
• What service levels or deliverables apply
• When either side can walk away

If those points matter commercially, they should not be left for assumptions.

Starting performance before the final contract is signed

This is a classic founder problem. To keep momentum, one side starts work, orders stock, shares systems access, books contractors or commits staff before the full agreement is ready.

That creates legal and practical risk. If negotiations later collapse, disputes can arise about payment, ownership of work product, confidentiality, liability for wasted spend and whether a broader contract was formed by conduct.

If early action is unavoidable, use an interim agreement or make sure the heads of terms clearly states what can happen during that interim period and on what written terms.

Using a template that does not fit the deal

A generic template can be a starting point, but it often misses the pressure points in the actual transaction. A lease negotiation has different risks from a wholesale supply arrangement or a business acquisition.

For example:

• A lease heads of terms may need to deal with fitout periods, incentives, make good, option terms and landlord approvals
• A supply term sheet may need to address forecast volumes, delivery risk, quality standards and stock ownership
• An investment term sheet may need to cover valuation, investor rights, dilution and conditions precedent

The document should reflect the commercial reality of the deal, not just the title of the template.

Ignoring who is actually signing

Businesses often negotiate under a trading name, but the legal party may be a company, trustee or individual. If the wrong entity signs, the commercial arrangement can become messy very quickly.

Before you sign, confirm the correct legal entity, the signatory's authority, and whether any parent company guarantee or personal guarantee is expected. This is especially important in SME deals where the other side may assume the founder can sign for any related business.

FAQs

Can heads of terms be legally binding even if they say “subject to contract”?

Yes. “Subject to contract” usually helps show the main deal is not final yet, but specific clauses can still be binding if the document says so or the wording clearly creates immediate obligations.

What is the difference between heads of terms and a full contract?

Heads of terms usually records the main commercial points and negotiation framework. A full contract sets out the detailed legal terms, risk allocation, remedies, definitions and operational rules that govern the relationship.

Should small businesses bother using heads of terms?

Often yes, especially where the deal is complex or the parties want to test alignment before paying for a detailed agreement. They are less useful for straightforward low-risk arrangements where a full contract can be prepared immediately.

Can I pull out after signing heads of terms?

It depends on the wording. If the document is wholly non-binding, you may usually walk away, subject to any binding carve-outs like confidentiality or exclusivity. If some or all terms are binding, pulling out may expose you to breach of contract claims.

What should I do before signing heads of terms?

Check whether it is binding, whether the commercial terms are clear, what conditions must be satisfied, whether any exclusivity period is acceptable, and whether your business is ready to comply with any immediate obligations.
