Heads of Terms in Australia: Binding Effects and Risks Before Signing

A heads of terms document can look harmless, especially when the deal feels urgent and the other side says it is only a summary. But this is where founders and business owners often get caught. Common mistakes include assuming the document is entirely non-binding, agreeing to exclusivity too early, and relying on verbal promises that never make it into the final contract.

If you are discussing an investment, business sale, commercial lease, supply arrangement or major services deal, heads of terms can shape the negotiation long before the long-form agreement is drafted. The practical problem is that a short document can still create real legal and commercial consequences.

This guide explains what heads of terms means in Australia, which clauses can bind you before the main contract is signed, what to check before you sign, and the common traps that can cost time, leverage and money.

Overview

Heads of terms is a preliminary deal document that records the main commercial points the parties have agreed, or are close to agreeing. In Australia, it may be fully non-binding, partly binding, or in some cases capable of creating enforceable obligations depending on the wording, context and conduct of the parties.

The main risk is signing a short document too quickly and only later discovering that key points were missing, ambiguous or already binding. Before you sign, the document should clearly state what is agreed, what still needs negotiation, and whether either side is expected to act before the formal contract is finalised.

• Whether the heads of terms is intended to be binding, non-binding, or partly binding
• Which clauses are enforceable now, such as confidentiality, exclusivity, costs, good faith, deposit arrangements or governing law
• Whether the commercial terms are clear enough to avoid later disputes
• What conditions must be satisfied before the deal proceeds, such as due diligence, finance, board approval, landlord consent or third party consents
• What is missing from the summary that needs to appear in the final contract
• Whether you are being restricted from negotiating with others before key risks are resolved
• How long the heads of terms lasts, and what ends it
• Whether the document lines up with emails, proposals, side letters and verbal discussions

What Heads of Terms Means For Australian Businesses

Heads of terms is usually the first serious written record of a proposed deal, and it often carries more weight than people expect.

You might also hear it called a term sheet, memorandum of understanding, letter of intent or deal summary. The label matters less than the actual wording. Australian courts generally look at substance over title when deciding whether obligations are enforceable.

For a business owner, heads of terms usually serves three purposes. It captures commercial momentum, narrows the points still in dispute, and gives lawyers a framework for contract drafting and the full agreement. That can save time and legal costs if the document is well prepared.

It can also create problems if it is signed too early. A rushed term sheet can lock in pricing, timing or exclusivity before due diligence is complete. It can also leave major issues open, which means each side thinks there is a deal, but they mean different things.

When businesses commonly use heads of terms

Founders and SMEs often see heads of terms before a more detailed contract in situations such as:

• investment rounds and shareholder negotiations
• business sales and asset purchases
• commercial leasing arrangements
• supply and distribution deals
• joint ventures and strategic partnerships
• major technology, software or outsourced services arrangements
• property development or fitout negotiations

In each of these situations, the document can influence leverage. Once a headline price or structure is written down, it becomes harder to move away from it later, even if deeper issues emerge.

Is heads of terms legally binding in Australia?

It can be, but not always. The answer depends on what the document says and how the parties behave.

Some heads of terms documents are clearly non-binding except for a few specific clauses. Others say the parties intend to negotiate a final agreement but still commit to confidentiality, exclusivity, costs or dispute resolution arrangements immediately. In some cases, the whole document may be treated as binding if it looks like the parties intended to be bound and the essential terms are sufficiently certain.

This is where founders often get caught. They sign because they think the real legal work comes later, but the term sheet already contains obligations that affect what they can do next.

Binding clauses often hidden in plain sight

Even where the commercial deal terms are stated to be non-binding, some sections are commonly drafted to take effect straight away, including:

• confidentiality obligations
• exclusivity or no-shop commitments
• break fees or cost-sharing provisions
• access rights for due diligence
• deposit handling arrangements
• governing law and jurisdiction clauses
• good faith negotiation obligations

These clauses can matter a lot in practice. An exclusivity clause can stop you speaking to a better buyer or investor. A due diligence clause can require you to hand over sensitive business information. A costs clause can leave you paying your own expenses even if the other side walks away late in the process.

Why wording and conduct both matter

A document does not exist in isolation. Courts can look at emails, drafts, meeting notes and what each side did after signing.

If both parties act as though there is already a deal, for example by paying a deposit, ordering stock, granting access to premises or beginning implementation work, that conduct can affect how the document is interpreted. Before you rely on a verbal promise that the paper is just a formality, make sure the written terms say exactly what you intend.

Legal Issues To Check Before You Sign

Before you sign a heads of terms document, you need to know exactly which obligations start now, which points remain open, and what commercial leverage you may be giving away.

1. Binding or non-binding status

The document should say clearly whether it is intended to be legally binding in whole, in part, or not at all. General statements such as “subject to contract” help, but they are not a complete safeguard if other wording points the other way.

The clearest approach is to identify each clause that is binding and each clause that is not. If you want only limited obligations to apply now, the drafting should say so expressly.

2. Essential commercial terms

Heads of terms should record the key deal points with enough certainty that both sides mean the same thing. Vague wording creates disputes later, especially where pressure builds to proceed quickly.

Check whether the document clearly covers:

• price or valuation
• what is being bought, supplied, leased or invested
• payment timing and milestones
• deposit amounts and refund rules
• completion dates and key deadlines
• who is responsible for transition, handover or implementation steps
• any restraints, warranties, indemnities or performance commitments expected in the final contract

If a point is commercially important, it should not be left to assumption.

3. Conditions precedent

Many deals should not proceed unless certain things happen first. Heads of terms often refers to these as conditions precedent.

Common conditions include:

• satisfactory due diligence
• finance approval
• board or shareholder approval
• landlord consent for assignment or licence arrangements
• regulatory or third party approvals
• agreement on formal contract terms

The condition should be clear about who benefits from it, how it is satisfied, and what happens if it is not met. If the wording is loose, one side may claim the condition has been met while the other disagrees.

4. Exclusivity and no-shop clauses

Exclusivity is often the most commercially significant binding clause in a heads of terms.

It can stop you from negotiating with other buyers, investors, suppliers or landlords for a set period. That may be reasonable if the other side is spending time and money on due diligence. But before you accept the provider's standard terms or a buyer's template, check the length of exclusivity, whether there are milestones, and whether the other side can simply delay while you are locked out of alternatives.

Good questions to ask include:

• How long does exclusivity last?
• Does it end automatically if due diligence drags on?
• Must the other side meet milestones or act in good faith?
• Can you respond to unsolicited approaches?
• What happens if the other side breaches confidentiality during the exclusive period?

5. Confidentiality and information sharing

A short term sheet is often followed by detailed information sharing. That creates risk if your financials, customer details, supplier terms, source materials or strategy documents are commercially sensitive.

The heads of terms should deal with what information can be used for, who can see it, whether advisers are covered, and what happens to the material if the deal does not proceed. If personal information is being shared, privacy obligations and data protection may also need attention, especially where customer or employee data is involved.

6. Costs, break fees and deposits

Do not assume each side bears its own costs unless the document says so. Some heads of terms include cost allocation, reimbursement obligations or break fee style clauses.

These provisions should be reviewed carefully. A break fee that looks modest can still distort negotiations. A deposit clause should also state where money is held, when it becomes refundable or non-refundable, and whether interest or deductions apply.

7. Good faith and negotiation obligations

Some heads of terms say the parties must negotiate in good faith toward a formal agreement. That can sound sensible, but it can also be uncertain if the scope is unclear.

If a good faith clause is included, it should be drafted carefully. You do not want to be accused of breaching it simply because your due diligence uncovered problems and you sought to renegotiate price or risk allocation.

8. Consistency with the final contract

Heads of terms should make clear that the final agreement will contain fuller legal protections and more detailed risk allocation.

This matters because business owners sometimes assume that anything not mentioned in the term sheet cannot appear later. In reality, the full contract may need detailed clauses about liability caps, intellectual property ownership, warranties, restraints, termination rights, service levels, security interests or dispute resolution. If you know those issues matter, flag them early instead of leaving them for a later fight.

9. Authority to sign

Before you sign, make sure the correct entity is named and the person signing has authority. This sounds basic, but errors are common where a founder negotiates personally while the deal is actually for a company, trust or group entity.

Misnaming the party can create confusion about who is bound and who bears the risk. If your business structure is part of the deal logic, confirm it early.

Common Mistakes With Heads of Terms

The most common mistake is treating heads of terms as a harmless placeholder when it can change your legal position immediately.

Signing before due diligence starts

Business owners sometimes agree to headline terms before they have tested the numbers, assets, legal risks or operational assumptions. That can leave them renegotiating from a weak position later.

Before you spend money on setup, transition or professional fees tied to the deal, make sure the term sheet leaves enough room for due diligence findings to matter.

Leaving key terms vague

A short document should still be clear on the core commercial deal. Ambiguous language around price adjustments, milestones, handover steps or scope often leads to disputes when the parties move to the long-form agreement.

If either side says “we will sort that out later”, ask whether the issue is genuinely minor. If it is central to value or risk, it should be recorded now.

Agreeing to broad exclusivity too early

Exclusivity can be reasonable, but broad no-shop terms without deadlines or milestones are risky. This is especially true where the other side has not yet committed resources or can withdraw freely.

A founder who accepts exclusivity too early may lose leverage, miss other opportunities and burn time while the deal stalls.

Relying on side conversations

Verbal statements made in meetings or calls often disappear once drafting starts. If something matters to your decision to proceed, it should appear in the document or be expressly preserved in writing elsewhere.

This is particularly important for statements about future funding, customer introductions, earn-out calculations, lease incentives, transition support or who bears hidden costs.

Using templates without reviewing the deal context

A generic template may not suit the transaction. A term sheet for an investment round is not interchangeable with one for a business purchase or commercial lease.

Different deals raise different issues, such as intellectual property ownership, transfer of employees, assignment consent, restraint clauses, PPSR concerns, or treatment of existing customer contracts. The document should fit the transaction, not just the heading.

Forgetting what happens if the deal falls over

Many term sheets focus on getting to “yes” and say little about what happens if negotiations end. That is a problem.

You should know:

• whether exclusivity ends automatically
• whether confidential material must be returned or destroyed
• whether deposits are refunded
• whether each side bears its own costs
• whether any obligations survive termination

These points matter most when the deal does not proceed smoothly.

Assuming all terms will be accepted later

Parties often agree broad commercial points and then become stuck on legal detail. That detail may affect value more than expected.

For example, a buyer may later demand extensive warranties, an investor may seek stronger control rights, or a landlord may insist on security and personal guarantees. Before you sign, ask which legal terms are likely to be heavily negotiated in the final contract.

FAQs

Is a heads of terms document enforceable in Australia?

Sometimes. It depends on the wording, the certainty of the terms, and whether the parties intended to be bound. Some clauses may be binding even if the overall deal is not yet final.

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

Heads of terms usually summarises the main commercial points and may leave detailed legal protections for the final agreement. A formal contract is the full document that allocates risk, sets out detailed obligations and deals with what happens if things go wrong.

Can I pull out after signing heads of terms?

Possibly, but not always without consequence. If the document contains binding clauses such as exclusivity, confidentiality, deposit obligations or costs provisions, those may still apply even if the main deal does not go ahead.

Should heads of terms say “subject to contract”?

Usually, yes if the intention is that the full deal is not binding until the formal contract is signed. But that phrase alone is not enough. The document should clearly identify which clauses are binding now and which are not.

When should a business get legal advice on heads of terms?

Ideally before signing, especially for investment, sale, lease, supply, technology or other high-value arrangements. Early advice is often cheaper than renegotiating after a poorly drafted term sheet has already limited your options.
