As your business evolves, the agreements you signed on day one often need to change. Maybe you’re renegotiating rent with your landlord, extending a key supply contract, or tweaking payment terms with a major customer.
In Queensland, a Deed of Variation is a practical way to formally update an existing contract or lease without starting from scratch. Done well, it’s clean, enforceable and reduces the chance of disputes. Done poorly, it can create confusion, void the change, or even trigger unexpected risks.
In this guide, we’ll explain what a Deed of Variation is in QLD, when to use one, how to execute it correctly, the risks to watch, and a simple step-by-step process to implement variations with confidence.
What Is A Deed Of Variation In Queensland?
A Deed of Variation is a binding document that amends specific terms of an existing agreement, while leaving the rest of the agreement intact. It’s commonly used to vary commercial leases, supplier and customer contracts, finance documents and other ongoing arrangements.
Unlike a simple email exchange, a deed clearly identifies the original contract, sets out the precise changes, and confirms that all other terms remain the same. Because deeds don’t require consideration (i.e. something of value exchanged), they are a reliable way to formalise changes even where one party isn’t providing new consideration for the variation.
If you’re weighing up whether to use an amendment letter, a full contract rewrite, or a deed, it helps to understand what a deed is under Australian law and why businesses use deeds for important changes.
When Should Your Business Use A Deed Of Variation?
You can vary many types of commercial arrangements. Common QLD use cases include:
- Commercial leases: Changing rent, extending or shortening the term, updating options, modifying permitted use, or adjusting maintenance obligations. If your lease is registered, the variation may also need to be noted on title to bind future owners.
- Supply and service agreements: Updating pricing, delivery schedules, service levels (SLAs) or scope. A deed ensures the updated terms can’t be disputed later as “informal”.
- Customer contracts or platform terms: For key enterprise customers on bespoke terms, a deed can document negotiated changes to payment milestones or acceptance criteria while retaining the original agreement framework.
- Finance and security documents: Extending repayment dates or adjusting covenants. If a security interest is affected, consider whether the registration on the PPSR needs updating.
- Franchise or distribution agreements: Altering territory or performance targets without rewriting the entire deal.
- Trust deeds: Some trust instruments allow variations via deed (strictly within the trust’s amendment power). This is a specialist area because a misstep can cause adverse tax outcomes-get advice and review your trust’s rules alongside general guidance like our overview of trusts in Australia.
As a rule of thumb, use a Deed of Variation when the change is material, long-term, or where the original contract requires amendments to be “by deed” or “in writing signed by both parties”.
How Do You Execute A Deed Of Variation In QLD?
To be enforceable, your deed needs to follow certain signing formalities and reflect clear drafting. Key points for Queensland businesses include:
1) Make It Clear You Are Executing A Deed
Use deed-style language (for example, “This Deed of Variation is made on…”), include clear recitals identifying the original agreement, and state that all other terms of the original contract remain unchanged.
2) Ensure The Right Execution Method
Companies can execute deeds under the Corporations Act using two directors or a director and company secretary, or a sole director/secretary for single-director companies. See how company execution works under section 127 for practical options.
Individuals must sign and, in practice, have their signature witnessed (ideally by an independent adult). If a party is signing via an authorised officer or attorney, confirm their authority in writing and attach evidence if necessary.
3) Electronic Signatures And Counterparts
Electronic signing is increasingly accepted for many commercial deeds, but there are exceptions and practical pitfalls (e.g. identity, witnessing, and consistency of versions). If you plan to sign electronically, check your deal’s specifics against this overview of wet ink vs electronic signatures, and align your process accordingly.
Where signatories are in different locations, it’s common to sign in separate counterpart documents. If you take that route, insert a clause permitting execution in counterparts and keep records tidy. Our explanation of signed in counterpart covers how to manage this cleanly.
4) Use The Right Parties And Capacity
Double-check who the contracting entity is (e.g. trading company vs holding company). If the original agreement involved a guarantor (such as a director’s guarantee in a lease), you’ll often need the guarantor to execute the deed too-otherwise you may lose the benefit of the guarantee for the varied terms.
5) Keep The Variation Precise
List exactly which clauses are replaced, deleted or inserted. Avoid vague words like “updated” without stating the new text. Include an “order of precedence” stating that the deed’s variation prevails if there’s any inconsistency with the original contract.
Do You Need To Register Or Notify Anyone?
After signing, think about follow-through to make the change effective against third parties and in your systems.
- Registered leases and real property interests: If your commercial lease is registered, the variation may need to be lodged with Titles Queensland so it binds future owners and mortgagees. Your property lawyer or leasing agent can help prepare the correct forms.
- PPSR security: If the variation alters collateral descriptions, parties, end dates or obligations in a way that affects a security interest, lodge a PPSR amendment to keep your registration accurate. If you’re new to this, start with the basics on what the PPSR is.
- Third party consents: Landlords, lenders, or franchisors sometimes need to consent to variations. Check your original agreement for any “no variation without consent” provisions and obtain written consent as part of the process.
- Internal systems: Update your billing, CRM and contract repositories so staff follow the updated terms. Circulate the deed to stakeholders who manage the relationship day to day.
Key Legal Risks To Watch
Most variations are straightforward, but a few recurring issues can trip up small businesses. Keep an eye on the following:
1) Original Contract Limits On Variation
Many agreements require amendments to be in writing and signed by both parties, or even specifically “by deed”. Others impose a strict consent process. If you don’t follow the clause to the letter, the variation could be ineffective. A short contract review before you draft the deed can save headaches later.
2) Authority To Sign
Has the person signing for the other side got clear authority? If not, the change can be challenged. This is where proper company execution under section 126 (agents) or section 127 is handy because it gives counterparties confidence the document is validly executed.
3) Guarantor And Third-Party Rights
If you rely on a director’s guarantee, bank guarantee or insurer consent, check whether your variation affects those protections. Often, guarantees are tied to the “original” contract terms and may not automatically extend to varied obligations unless the guarantor also signs the variation.
4) Unfair Contract Terms (UCT)
If you’re varying a standard-form contract with a small business or consumer, the Australian Consumer Law’s UCT regime may apply. Terms that cause a significant imbalance, aren’t reasonably necessary, and disadvantage the other party can be void and attract penalties. When you’re adjusting liability caps, termination rights or auto-renewals, consider a targeted UCT review and redraft.
5) Misleading Or Confusing Communications
Side emails or sales materials that conflict with the deed can create risk under section 18 (misleading or deceptive conduct) of the ACL. Keep communications aligned with the final deed and avoid informal “promises” outside the document.
6) Tax, Duties And Registration Nuances
Some variations can have tax consequences-particularly for trusts or finance documents-and certain property-related variations may involve lodging instruments. While Queensland has minimal duties on many commercial variations, always check whether your specific change could trigger a duty or filing requirement. When in doubt, get advice before you sign.
Step-By-Step: Drafting And Implementing A Deed Of Variation
Here’s a practical process you can follow to vary a contract or lease with minimal fuss.
Step 1: Revisit The Original Contract
- Confirm the parties, signatories and any guarantors.
- Locate the variation clause-does it require a deed or third-party consent?
- Identify exactly which clauses you want to change and why (price, term, scope, rent, etc.).
Step 2: Choose The Right Instrument
- Use a Deed of Variation for substantive changes where certainty matters, consideration is unclear, or the original contract requires a deed.
- Use a Deed of Novation if you’re replacing a party (e.g. moving the contract to a new company).
- Use a Deed of Assignment where you’re transferring rights (subject to consent) but keeping obligations with the original party.
If you’re unsure, a short consultation plus a contract amendment or fresh deed often resolves the uncertainty quickly.
Step 3: Draft The Deed Clearly
- Title the document “Deed of Variation” and include recitals that reference the original agreement’s date, title and parties.
- List clause-by-clause changes, using clear “deleted and replaced with” wording.
- Confirm that all other terms remain unchanged and continue in full force and effect.
- Add standard terms such as counterparts, electronic signing (if appropriate), governing law (QLD, if relevant), and confidentiality.
Step 4: Line Up Approvals And Consents
- Get internal approvals (e.g. board or director sign-off for companies).
- Obtain landlord, lender, franchisor or guarantor consents if required by the original contract.
Step 5: Execute Properly
- Have the deed executed by the correct entity under section 127 (for companies) or by authorised signatories with witnesses (for individuals).
- If signing electronically or in counterparts, make sure the deed includes clauses allowing this and that your process aligns with your policies on electronic signatures and counterparts.
Step 6: Implement The Change
- Register or lodge variations where needed (e.g. registered leases, security interests on the PPSR).
- Update billing, renewal dates, fulfilment schedules and contact lists.
- Store the executed deed with the original agreement in your contract management system.
What Documents And Services Can Help?
Depending on what you’re varying, these documents and services can streamline the process and reduce risk:
- Deed of Variation: A tailored deed to amend specific terms of an existing contract or lease while keeping all other provisions the same.
- Contract Review: A quick legal health check on the original agreement so your variation complies with consent and amendment clauses.
- Deed of Novation: Used when you need to replace a party and transfer both rights and obligations to a new entity.
- Deed of Assignment (Contract): For transferring contractual rights, subject to consent requirements.
- Commercial Lease Review: If your variation relates to rent, term, options or other lease provisions, a lease review can flag registration and guarantor issues early.
- UCT Review and Redraft: Ensures updates to standard-form terms don’t fall foul of unfair contract term prohibitions.
- Contract Amendment: When a deed isn’t necessary, a structured written amendment can still update terms cleanly.
