How to read a contract of sale before you sign

Updated 2026-07-09 · 8 min read

A contract of sale is the most significant document in any property transaction, outlining the legal obligations of both the buyer and the seller. Understanding the fine print ensures you are aware of your rights regarding deposits, settlement dates, and property conditions. This guide explains the essential components of Australian property contracts and the specific details you must verify before signing.

Understanding the structure of the document

The contract of sale is a legally binding agreement that dictates how the ownership of a property will transfer from the vendor to the buyer. In Australia, the format of this document varies by state and territory, though most follow a standard template developed by the local Law Society or Real Estate Institute. It consists of a core contract page, general conditions that apply to most sales, and special conditions tailored to the specific transaction. On Home24, where owners list properties directly, these documents are prepared by the seller's legal representative and should be requested early in the negotiation process.

Before you sign, you must identify whether the contract is for a private treaty sale or an auction. Auction contracts are typically unconditional, meaning once the hammer falls, you are legally committed to the purchase without a cooling-off period. In a private treaty sale, there is often more room to negotiate terms and include protective clauses. Regardless of the method, the contract must include the correct legal names of all parties, the property address, and the title reference numbers to ensure the document is valid and enforceable under Australian law.

Financial terms and settlement dates

Every contract must clearly state the purchase price and the deposit amount required to secure the property. The deposit is usually 10 percent of the purchase price, though this is often negotiable to a lower figure like 5 percent if the seller agrees. You should check how the deposit is to be paid and who will hold it, which is typically the seller’s solicitor or a licensed real estate agent in a trust account. Be wary of any clauses that suggest the deposit be released to the seller before settlement, as this increases your financial risk.

The settlement period is the timeframe between signing the contract and the final transfer of funds and title, commonly set at 30, 60, or 90 days. You must ensure this date aligns with your ability to secure finance and your plans for moving. If you are selling another property simultaneously, you may need to negotiate a specific date to avoid the need for expensive bridging finance. Always check the default interest clauses, which outline the financial penalties you will face if you fail to settle on the agreed date.

Checking inclusions and property condition

The contract will include a list of inclusions and exclusions, which specifies what stays with the property and what the seller will take with them. Standard inclusions usually cover fixed floor coverings, light fittings, and window treatments. However, you should never assume that portable items like dishwashers, garden sheds, or wall-mounted televisions are included unless they are explicitly written into the contract. If you expect a specific item to remain, ensure it is listed in the schedule of inclusions to avoid disputes on settlement day.

Equally important are the exclusions, which are items the seller intends to remove that might otherwise be considered fixtures. This might include a specific chandelier with sentimental value or a prized rose bush from the garden. Carefully reviewing this list prevents surprises when you collect the keys. If the property has significant debris or unwanted furniture, you can also request a special condition requiring the vendor to remove all rubbish and ensure the property is in a clean state prior to the final inspection.

Mandatory disclosures and easements

Each state has specific disclosure regimes that require the seller to provide certain documents, often referred to as a Section 32 in Victoria or a Disclosure Statement in other regions. These documents include title searches, plan diagrams showing easements, and certificates from local councils or water authorities. You must check for easements, which are rights granted to others to use a portion of your land, such as for sewerage pipes or electricity cables. An easement can restrict where you are allowed to build extensions or swimming pools.

Zoning information is another critical disclosure that dictates how the land can be used. For example, a property zoned for residential use might have restrictions on running a business or building multiple dwellings. You should also look for any notices or orders from authorities, such as a planned road widening that might take a portion of the front yard. If these mandatory disclosures are missing or inaccurate, you may have the right to withdraw from the contract, though you should consult a conveyancer to confirm your specific legal standing.

Common protective special conditions

Subject to finance is one of the most common protective clauses for buyers. It allows you to withdraw from the sale if your bank does not provide formal mortgage approval by a specific date. Even if you have pre-approval, this clause is vital because the bank still needs to conduct a valuation of the property you are buying. Without this clause, you could be forced to proceed with the purchase even if your lender refuses the loan, which often leads to the loss of your entire deposit and potential legal action for damages.

A subject to building and pest inspection clause is equally important. This gives you the right to have a professional inspector evaluate the property for structural issues, dampness, or termite infestations. If the report identifies major defects, this clause allows you to negotiate a lower price or exit the contract entirely. Ensure the wording of these clauses is precise; for example, specify that the inspection must be 'satisfactory to the buyer' to give yourself the broadest protection possible. Professional inspections typically cost between 400 and 800 dollars depending on the property size.

Navigating the cooling-off period

A cooling-off period provides a window for you to change your mind after signing, but the rules vary significantly across Australia. In New South Wales and the ACT, it is usually five business days, while in Queensland and Victoria, it is typically five days and three days respectively. Western Australia and Tasmania do not have a mandatory cooling-off period unless it is written into the contract. It is crucial to remember that if you waive your cooling-off rights or buy at auction, the contract becomes immediately binding.

If you decide to cancel the contract during the cooling-off period, you will likely have to pay a small penalty to the seller. This is usually around 0.25 percent of the purchase price. While this can be several thousand dollars, it is a fraction of the total cost of the property and acts as a safety net if you discover a major issue immediately after signing. Always verify the exact duration and penalty amount with your legal representative, as these figures and rules are subject to legislative changes by state governments.

Common mistakes and final checks

One of the most frequent mistakes buyers make is failing to check the land tax and council rate adjustments. At settlement, these costs are split between the buyer and seller based on the portion of the year each party owns the property. You should ensure the contract clearly states how these adjustments will be calculated. Another error is neglecting to verify the property’s title type, whether it is Torrens Title, Strata Title, or Company Title, as each carries different ownership rights and ongoing financial obligations like strata levies.

Finally, never sign a contract that contains blank spaces or verbal promises that have not been put in writing. If a seller promises to fix a leaking tap or a broken fence, that promise must be included as a special condition in the contract to be legally enforceable. Reading every page, including the fine print of the general conditions, is tedious but necessary. Engaging a qualified conveyancer or solicitor to perform a formal contract review is the most effective way to avoid these common pitfalls and ensure your interests are fully protected throughout the transaction.

Common questions

What is a cooling-off period and how does it work?
A cooling-off period is a set time after exchanging contracts where a buyer can withdraw, usually by paying a small percentage of the price. The duration and availability of this period vary by state, and it typically does not apply to properties bought at auction.
What does it mean to buy a property subject to finance?
A conditional offer includes specific requirements that must be met for the sale to proceed, such as a satisfactory building inspection or formal finance approval. If these conditions are not met within the agreed timeframe, the buyer can usually exit the contract without losing their full deposit.
How much does a solicitor charge to review a contract?
Professional contract reviews generally range from 200 to 600 dollars, depending on the complexity of the document and the location. Engaging a solicitor or conveyancer early can prevent costly mistakes that far outweigh the initial review fee.
Can I pull out of a house sale if the seller lied?
State laws require vendors to disclose certain information, such as zoning, easements, or structural defects they are aware of. If a seller fails to provide these mandatory disclosures, the buyer may have a legal right to rescind the contract before settlement occurs.
