Option Agreements: Flexible Property Deals with Hidden Risks

Option Agreements can be powerful tools in Queensland property and commercial transactions. They give one or both parties flexibility to buy or sell property in the future without committing immediately.
But Option Agreements are highly technical legal documents and a single poorly drafted clause could cost you thousands in tax, stamp duty, or lost opportunities.
At Enterprise Legal, our team of qualified property and commercial lawyers (not just conveyancers) helps clients across Queensland negotiate, draft, and review Option Agreements to protect their commercial interests and avoid costly traps.
Whether you’re a developer looking to secure land for a future project, or a property owner approached with an offer for an Option, we’ll ensure you understand your rights, risks, and obligations in clear, practical terms. We also offer our services on a fixed or capped fee basis wherever possible, so you can plan with confidence.
Types of Option Agreements
Option Agreements in Queensland come in several forms:
Call Options
- Gives the buyer the right (but not the obligation) to purchase the property within a set timeframe, at a pre-agreed price.
- Often used by developers to secure sites while they obtain development approvals.
- The seller is locked in if the buyer exercises the option.
Put Options
- Gives the seller the right to require the buyer to purchase the property at an agreed price within a certain period.
- Less common but sometimes used in commercial arrangements or as security in complex transactions.
Put and Call Options
- Combines both rights:
- The seller can force the sale (put).
- The buyer can choose to proceed (call).
- Often used to:
- manage stamp duty timing
- give developers flexibility
- keep deals off public records until certain milestones are met.
Why Use Option Agreements?
Option Agreements can be valuable tools for both sellers and buyers because they:
- Secure property without immediate commitment.
Developers can tie up sites while seeking planning approvals without paying the full purchase price upfront. - Lock in a price for future purchase.
Buyers can benefit from potential capital growth during the option period. - Allow time for due diligence and approvals.
Buyers have time to investigate zoning, contamination, planning approvals, and financing. - Assist with Capital Gains Tax (CGT) planning.
Option Agreements can sometimes help sellers manage the timing of CGT events for better tax outcomes. - Allow time to set up business structures.
Parties can establish trusts, companies, or joint ventures before exercising the option, ensuring the ultimate purchaser or seller is structured tax-effectively. - Manage stamp duty timing.
Correctly structured options can delay duty liability until the contract is exercised. - Spread financial risk.
Sellers can secure a potential buyer and option fee while retaining ownership if the deal doesn’t proceed.
But with these benefits come significant risks; especially around tax, stamp duty, and legal enforceability. This is not an area for DIY contracts.

Why Choose Enterprise Legal for Option Agreements?

Seller Disclosure Statement: When Is It Needed?
From 1 August 2025, sellers of residential property in Queensland, including those selling freehold retirement village units or lots in lifestyle resorts, must provide a legally compliant Seller Disclosure Statement before signing a contract under the new Property Law Act 2023.
This means:
- Exercising an option triggers disclosure requirements.
- Even if the option was signed years earlier, the seller disclosure must be up-to-date and compliant at the time the contract is formed.
Failing to provide proper disclosure could allow the buyer to terminate the contract or claim compensation, even after signing.
At Enterprise Legal, we:
- Prepare or review Seller Disclosure Statements for freehold retirement properties.
- Ensure all documents, body corporate records, and financial disclosures are accurate and compliant.
- Protect your rights whether you’re buying or selling.
