Heads of Agreement: Binding Terms and Legal Effect

What Heads of Agreement Mean

Heads of agreement are a preliminary record of terms that parties have agreed or propose to agree. They can settle a bargain immediately, preserve negotiations for a later contract or combine a non-binding proposal with specific binding clauses.

These arrangements have different consequences for the client:

Arrangement	What the parties intend	Practical consequence
Non-binding outline	The transaction depends on entering a final agreement	The outline records a negotiating position without creating the proposed transaction obligations
Binding bargain awaiting documentation	The agreed obligations bind now, with fuller drafting to follow	An unsigned final document does not itself release either party from the existing bargain
Selected clauses binding immediately	Identified promises bind now while the transaction remains conditional on final agreement	A confidentiality obligation can operate even though the proposed settlement payment is not yet binding

In Masters v Cameron, the High Court distinguished immediate agreement from negotiations awaiting formal execution. Its analysis requires reading the actual arrangement, including any condition attached to assent.

The expression “heads of terms” also describes preliminary commitments. Read the promises themselves to decide their effect.

A short document can therefore have substantial legal effect. Its length and the expectation of a longer deed do not decide whether the parties already have a contract.

When the Terms Can Be Enforceable

Heads of agreement can be enforceable when the parties objectively agree to binding obligations with sufficiently certain terms and the other requirements for a contract. Identify the parties and consideration as well as what each side promises to do.

In Ermogenous v Greek Orthodox Community of SA Inc, the High Court explained the objective inquiry. The court examines what the parties’ statements and actions convey in their circumstances. A private intention to remain unbound does not replace what a party communicates.

Separate the Preliminary-Agreement Categories

Masters v Cameron identifies three classes of arrangement. First, parties agree their bargain and intend immediate performance, with a fuller document to restate it. Second, they conclude the bargain but make performance of one or more terms conditional on formal execution. Third, they intend no concluded bargain until execution.

The first two classes create binding contracts. In the third, the proposed bargain remains unformed. A later recognised fourth category concerns immediate agreement on existing terms while parties expect a substitute contract containing additional agreed terms. The Fair Work Commission’s Full Bench discussion explains why later disagreement about a deed need not undo an already binding bargain.

These categories help explain the result. They do not replace examination of the actual words and circumstances.

Ask What the Condition Prevents

A formation condition prevents the proposed contract from arising until the specified event. A performance condition can leave a contract in place while postponing a duty, such as payment until signing.

Compare these fictional instructions:

• Formation intended: “Neither party is bound to settle unless both parties execute the final settlement agreement.”
• Performance intended: “The parties are bound to settle on these terms now. The settlement sum becomes payable five business days after both parties execute the agreed settlement document.”

The second choice needs a settled bargain and a workable obligation concerning the final document. If substantial release terms remain undecided, resolve whether they prevent present agreement. Writing “binding” above incomplete negotiations cannot supply the missing bargain.

For a fictional $80,000 financial settlement, compare the signed heads with the emails recording assent and any approval still required. If neither party is bound until execution, an agreed figure alone does not establish a settlement contract. If the bargain binds now but payment awaits execution, preserve the agreed payment trigger and evidence of when execution occurs. A transfer receipt can prove performance of a payment duty. It cannot decide whether the parties intended that duty to exist.

Read “subject to contract” in context. Masters v Cameron gives that wording substantial weight while rejecting an inflexible rule that the formula always produces the same result.

Certainty also requires content that a court can identify. In Crown Melbourne v Cosmopolitan Hotel, an uncertain renewal assurance failed to create the claimed collateral contract. State the promised action and its limits instead of relying on an assurance that the client will be treated favourably.

Draft the Commitments the Client Intends to Make

Draft each obligation with an identified party, an ascertainable action and an express starting point. Record unresolved issues separately so the client can distinguish an existing duty from a proposal.

Before circulating heads, settle the following drafting instructions:

• Identify each legal person and the capacity in which they act. Distinguish a company from its director and a personal claim from a claim brought as estate representative.
• Record the agreed obligations and the consideration supporting any immediately binding promises.
• List outstanding terms and state whether agreement on them is required before the proposed transaction binds.
• Define each approval or other condition, who must pursue it and how satisfaction is recorded. Address failure or delay expressly.
• Confirm settlement authority, including any limit on the representative’s instructions. Identify any further approval required before commitment.
• State confidentiality exceptions for legal advice, required disclosure and implementation. If exclusivity is required, define its activity and duration.
• Allocate drafting costs and decide whether that obligation binds before the transaction does.

Annotate the Intended Legal Effect

This fictional extract concerns proposed settlement between Alder Pty Ltd and Birch Pty Ltd. It illustrates a partially binding arrangement. It assumes authorised signatories and consideration in the parties’ mutual confidentiality promises.

Clause 1: Alder proposes to pay Birch $80,000 in settlement of the identified proceedings. This proposal creates no payment obligation before both parties execute the final settlement agreement.

Clause 2: On signing these heads, each party promises to keep these negotiations confidential. Disclosure is permitted to its legal advisers, as required by law and as reasonably necessary to implement an executed settlement.

Clause 3: Each party bears its own drafting costs. Clauses 2 and 3 bind on signature. The remaining terms record proposals only.

The payment proposal in clause 1 remains unformed. Under clause 2, a present mutual confidentiality obligation has stated exceptions. Clause 3 separates current cost responsibility from the uncompleted settlement.

If the client instead wants an immediately binding settlement, that requires different instructions and wording. Agree the settlement obligations and the scope of the intended release before adopting that choice. Keep detailed final provisions within the deed of release drafting process.

Heads of Agreement in Family Law

Family-law property settlements require the applicable statutory formalisation. Commercial heads alone do not replace consent orders or a financial agreement that meets the relevant legal requirements. The Federal Circuit and Family Court explains the formal options. Identify the applicable family-law regime and complete its requirements before advising that the property settlement is binding.

Record Payment Terms Without Ambiguity

Record what each payment does, when it is due and the evidence that will establish receipt. Calling every amount a deposit can obscure whether it reduces the settlement sum or has some separate agreed purpose.

Payment description	What the heads need to resolve	Evidence to retain
Settlement sum	Total compromise amount, included claims and whether costs or interest sit within it	Agreed calculation and recipient’s receipt record
Deposit	Purpose, holder, credit against the total and agreed treatment if the transaction fails	Holding instructions and the account receipt
Instalment	Amount, due event or interval and allocation against the total	Schedule showing each receipt and remaining balance
Disputed balance	Amount still contested and the process for resolving it	Reconciled account and each party’s stated position

In a fictional $80,000 settlement, a $10,000 initial payment leaves $70,000 if the parties expressly credit it against that total. Two subsequent instalments of $35,000 discharge the remaining principal. State whether an interest or costs obligation exists separately so the schedule does not conceal an additional amount.

Specify the recipient and a secure process for confirming payment instructions. Define whether payment occurs on cleared receipt and retain the transfer reference alongside the receiving account record. A remittance advice records an instruction or reported transfer. Check the receipt record against the contractual payment event before recording performance as complete.

If formal documentation stalls, identify whether the payment obligation already exists or remains conditional. Apply the agreed drafting timetable and escalation mechanism. A missed target for exchanging drafts does not itself establish a right to withdraw from a binding settlement.

If a proposed payment is missed, examine the actual duty, due event and any notice or remedy clause before taking action. Neither the label “deposit” nor a missed instalment creates an automatic forfeiture or termination right. Record any agreed extension and its effect on the remaining obligations.

Move From Preliminary Terms to Final Documents

Before signature, confirm that the heads produce the legal effect the client has authorised. Compare the final version with the instructions and explain every promise that starts immediately.

1. Confirm the parties and capacity. Retain the client’s authority and identify any court, corporate or other approval the proposed settlement requires.
2. Match the signature method to the actual party and document. For Australian companies, distinguish an authorised agent under section 126 from execution by the company under section 127 of the Corporations Act.
3. Resolve outstanding conditions. Identify who satisfies each condition and whether it affects formation or performance. Check any jurisdiction-specific writing or execution requirement for the transaction.
4. Compare the proposed final release with the settlement instructions. Agree which claims and parties it will cover before treating it as routine drafting.
5. Record the next drafting step and its owner. Give the client a schedule of current obligations and the events that activate deferred obligations.

Signing carries legal consequences. In Toll v Alphapharm, the High Court explained the ordinary significance of signing contractual terms. Resolve uncertainty before the client signs, including uncertainty about what remains for later agreement.

If a party acts inconsistently with the heads, preserve the complete correspondence and each draft. Build a chronology identifying assent, conditions and subsequent performance. Keep payment records against the relevant obligation, including any acceptance of a changed timetable.

Then identify the specific promise said to be enforceable and the evidence establishing its commencement and breach. That analysis determines whether the next step concerns enforcing an existing bargain or completing negotiations for one.
