Is a Letter of Offer Binding in Victoria?

We get asked this a lot by first home buyers who leave a Saturday inspection in Brunswick, Preston or Bentleigh, then realise they signed a one-page ‘Letter of Offer’ at the agent’s desk without getting it checked.

The short answer: In Victoria, a letter of offer is often intended to be a step towards the formal Contract of Sale, not the final binding deal. But it can become binding if it is written, signed, contains the key sale terms, and shows both sides meant to be bound before the formal contract was signed. The safest wording is ‘subject to formal contract being signed by both parties’ and, ideally, ‘subject to conveyancer review of the Contract of Sale and Section 32’.

What is a letter of offer in Victoria?

A letter of offer is a short written offer to buy a property, usually used before the full Contract of Sale is signed. It often records the purchase price, buyer name, property address, proposed settlement period, deposit details and any conditions.

Melbourne agents use these documents because they make offers easier to compare. If three buyers are circling the same townhouse in Thornbury, a vendor wants to see more than a quick phone call. A written offer gives the vendor a clear price and a starting point for contract paperwork.

You might see the same idea called:

a letter of offer
an expression of interest
a heads of agreement
an offer form
an email confirming agreed terms

The heading is not the whole story. A document called an ‘expression of interest’ may still create risk if it reads like a final deal. A short email chain can also be risky if it locks in the parties, property, price, deposit and settlement date without saying the deal is subject to the formal contract.

Letters of offer are not bad documents. They can help everyone move from inspection chatter to a clear written proposal. The issue is not the form itself, but whether the buyer has kept enough protection while the Section 32, finance position and inspection results are still being checked.

If you are still working through the early steps of making an offer on a house, treat every written message as something that could be looked at later.

Can a letter of offer be binding before the Contract of Sale?

Yes, a letter of offer can be binding before the Contract of Sale if the wording and conduct show a final agreement. The old rule of thumb, ‘it is not binding until the contract is signed’, is too simple.

Victorian conveyancing sits beside general contract law. Section 126 of the Property Law Act 1958 (Vic) deals with agreements for interests in land being in writing and signed by the party to be charged. That does not mean only a standard Contract of Sale can ever matter. A signed pre-contract document can cause real trouble if it has the essential terms and no clear protective wording.

The classic way courts sort this out comes from Masters v Cameron. In plain English, a pre-contract document usually falls into one of three baskets:

Binding now, formal contract later: The parties have already agreed the deal. The later Contract of Sale simply tidies it up.
Binding now, but performance waits: The parties are bound, but some steps depend on the formal document being signed.
Not binding yet: The parties do not intend to be bound until the formal Contract of Sale is signed.

Most buyers expect basket three. The risk is signing wording that points to basket one or two.

Why does Patel v Sengun matter for Victorian property buyers?

Patel v Sengun is a warning that a short ‘heads of agreement’ can still have teeth. In that Victorian Court of Appeal case, a signed heads of agreement for land at St Leonards was treated as enough to require the vendor to proceed with the next contract step.

The practical lesson for Melbourne buyers is simple: do not assume a document is harmless because the agent says ‘contracts will follow’. If the document names the buyer and vendor, identifies the property, states the price, records the deposit and sets a settlement period, it may be much more than a casual note.

In our practice, we’ve seen this concern come up when a buyer signs a one-page offer after a busy inspection, then the agent asks for solicitor details and a holding deposit that same afternoon. The paperwork may look informal, but the overall exchange can start looking more serious than the buyer intended.

What words should I add before signing a letter of offer?

The best protective words are ‘subject to formal contract being signed by both parties’. That phrase tells the agent, vendor and any later reader that you are not agreeing to a final purchase until the proper Contract of Sale is signed.

Other useful wording includes:

‘This letter of offer is non-binding and subject to formal contract.’
‘No binding agreement exists until the Contract of Sale is signed by both parties.’
‘Subject to the purchaser’s conveyancer approving the Contract of Sale and Section 32 vendor statement.’
‘Subject to finance approval by the purchaser’s lender.’
‘Subject to a satisfactory building and pest inspection.’

Do not rely on a verbal promise from the agent that ‘it is just a form’. If the protection matters, put it in writing before you sign.

What should I check before signing anything at the agent’s office?

Check the wording, the terms and the payment request before you sign. A quick pause at this point can save a very messy dispute later.

Use this buyer checklist before signing a letter of offer:

Look for ‘subject to formal contract’. If it is missing, ask for it to be added.
Check the key terms. Price, property, buyer, vendor, deposit, inclusions and settlement date all matter.
Confirm the deposit status. A small holding deposit is not the same as the usual contract deposit. Ask whether it is refundable, where it will be held, and what triggers release or return.
Do not sign under pressure. You can ask to take the offer form home or email it to your conveyancer.
Keep conditions clear. Finance approval, building inspection, pest inspection and Section 32 review should be written plainly.
Watch your texts and emails. A casual ‘yes, we agree’ message can look stronger than you meant if it sits beside a clear price and settlement date.

This is especially relevant for private sale negotiations in Melbourne’s inner suburbs, where a buyer might be nudged to move quickly because another party is inspecting the same afternoon. Speed is fine. Blind signing is not.

What if I have already signed a letter of offer?

If you have already signed, gather every document and message, then get advice before you send anything else. That includes the offer form, emails, SMS messages, receipts for any deposit, agent notes and the draft Contract of Sale if it has been issued.

The review should focus on:

whether the document says ‘subject to contract’ or similar
whether all essential terms are present
whether both sides signed or confirmed the terms
whether a deposit was paid
whether the vendor relied on the offer, such as taking the property off the market
whether later messages made the offer look final

We’ve had clients come to us after signing forms at display suites for off-the-plan apartments, after Sunday night email exchanges following a passed-in auction, and after paying a small holding deposit on a private sale in the outer growth corridors. The answer is not always the same. A careful review of the Contract of Sale and related messages is the fastest way to work out your next move.

Try not to negotiate from memory. Agents and vendors often have their own version of what was said at the inspection, so the paper trail matters. Save screenshots, download attachments and keep bank transfer receipts for any holding deposit.

Does Victorian cooling off apply to a letter of offer?

Victorian cooling off usually applies to a signed Contract of Sale for a private residential sale, not to a loose letter of offer on its own. The clock generally starts when the purchaser signs the contract, not when a preliminary offer form is signed.

The cooling-off period under section 31 of the Sale of Land Act 1962 is three clear business days for many private residential sales. If a buyer cools off, the usual cost is the greater of $100 or 0.2 per cent of the purchase price.

There are key exceptions. Cooling off does not apply to some auction-related purchases, commercial or industrial property, rural property over 20 hectares mainly used for farming, buyers who are companies, estate agents or agents’ representatives, or buyers who have already signed a contract for the same property on substantially the same terms.

So, if you signed a letter of offer on Saturday and the Contract of Sale on Wednesday, your cooling off question usually turns on the Wednesday contract, not the Saturday letter. Get advice quickly, because three clear business days can pass faster than expected.

Frequently asked questions

Is a letter of offer legally binding in Victoria?

A letter of offer is not always legally binding in Victoria, especially if it says ‘subject to formal contract’. It can become binding if it is signed, contains the essential sale terms, and shows that both sides intended to be bound before the formal Contract of Sale was signed. The wording matters more than the document title.

Can the seller still accept another offer after I’ve signed a letter of offer?

Yes, the seller can often accept another offer if no binding Contract of Sale has been signed and the letter of offer is clearly subject to contract. This is commonly called gazumping. It can feel harsh, but in Victoria the safest point for a buyer is usually exchange of signed contracts.

What’s the difference between a letter of offer and a Contract of Sale?

A letter of offer is usually a short document setting out what the buyer is willing to pay and any conditions they want. A Contract of Sale is the formal sale document that records the binding purchase terms, settlement obligations and statutory rights. The Contract of Sale carries much heavier legal consequences.

Does an expression of interest work the same way as a letter of offer?

An expression of interest can work in a similar way to a letter of offer. If it is clearly non-binding and subject to contract, it is usually a preliminary step. If it contains all essential terms and shows final agreement, it can create legal risk.

Can I be bound by an email or SMS to the agent?

Yes, an email or SMS exchange can create risk if it contains the key deal terms and shows final agreement. Do not confirm price, deposit, settlement and acceptance by message unless you also make it clear that everything is subject to the formal Contract of Sale being signed by both parties.

How do I protect myself when signing a letter of offer in Melbourne?

Add ‘subject to formal contract being signed by both parties’ before you sign. Also make the offer subject to conveyancer approval of the Contract of Sale and Section 32, plus any finance or inspection conditions you need. Send the form to your conveyancer before paying a holding deposit.

What if I’ve signed and the agent now says I’m locked in?

Ask for a copy of everything you signed, then contact a conveyancer before replying to the agent. Whether you are locked in depends on the wording, the essential terms, signatures, deposits and later conduct. Do not send a message saying you agree, withdraw or refuse until you know where you stand.
