Leasing a commercial space is a big commitment for any Australian business. But businesses evolve - you might expand, restructure, sell, or simply need a different location. When that happens, transferring your current lease to a new tenant can be a smart way to move forward without breaking the lease.
This is where a deed of assignment of lease comes in. It’s the formal document that records the transfer of your rights and obligations to an incoming tenant (the assignee), usually with the landlord’s written consent. Done properly, it protects you, keeps you compliant, and reduces the risk of disputes later.
In this guide, we’ll unpack what an assignment of lease actually is, when you might use one, how the process works in Australia, the typical documents involved, and the compliance points to watch - including retail lease disclosure, titles registration, stamp duty and GST. We’ll also walk through a practical step-by-step checklist so you can approach the process with confidence.
What Is A Deed Of Assignment Of Lease?
Assigning a lease means transferring your legal position under an existing lease to another party. The outgoing tenant (assignor) steps out, and the incoming tenant (assignee) steps in - taking over rights like exclusive possession and obligations like rent, outgoings and repairs from a set date.
This is different from a sublease. With a sublease, you remain the tenant under the head lease and grant a separate right of occupation to someone else. With an assignment, your existing lease is transferred to the new tenant.
Why the transfer is documented as a deed
A deed of assignment of lease is the formal instrument that gives effect to the transfer. Deeds carry additional formality under Australian law and are often required by leases. A well-drafted deed typically:
- Identifies the lease being assigned, the premises, and the effective assignment date.
- Records the landlord’s consent (whether within the deed or via a separate consent document).
- Allocates responsibility for accrued obligations (e.g. unpaid rent, make-good, existing breaches).
- Sets out whether the outgoing tenant is released from future liability or remains secondarily liable.
- Confirms any guarantees required from the assignee’s directors or related entities.
The parties who usually sign are the outgoing tenant (assignor), the incoming tenant (assignee), and the landlord. If the lease has guarantors, replacement or additional guarantees may also be required at assignment.

When Would You Use A Deed Of Assignment Of Lease?
Businesses use assignments for many reasons. Common scenarios include:
- Selling your business: If a buyer wants to keep trading from your premises, the lease usually needs to be assigned to them as part of completion. This often sits alongside a Business Sale Agreement or a broader sale package.
- Restructuring or relocating: You might merge operations, pivot to online, downsize, or expand to a different site - and no longer need the current premises.
- Risk or hardship management: If trading conditions change and you can’t continue in the space, transferring the lease to a suitable replacement tenant (with consent) can reduce ongoing exposure.
In each case, the deed is your record that the transfer is valid and enforceable, and that liabilities are allocated as intended.
How Does Assigning A Lease Work In Australia?
Assignments are more than “handing over the keys.” There’s a legal process to follow, and your lease will set out specific requirements. Getting the details right can prevent disputes and protect you from ongoing liability.
Landlord consent is almost always required
Most commercial and retail leases require prior written consent from the landlord to assign. Landlords can assess the assignee (e.g. financial capacity, business experience, references) and set reasonable conditions before consenting. Some leases also allow landlords to recover reasonable legal and administrative costs related to the consent process.
Attempting to assign without the landlord’s consent can constitute a breach of lease and may leave the outgoing tenant liable even after vacating.
What the deed should cover
Once consent is obtained, the deed of assignment should clearly cover:
- Parties and premises: The assignor, assignee, guarantors (if any), landlord and the precise leased area.
- Assignment date: When the assignee’s obligations start (and the assignor’s obligations end, subject to any continuing liability).
- Accrued obligations and make-good: Who is responsible for pre-assignment arrears, repairs or make-good (and how they will be handled on completion).
- Continuing liability: Whether the assignor is released, or remains liable on a secondary basis if the assignee defaults (this depends on the lease, the deed and any applicable legislation).
- Security and guarantees: Any new bank guarantees, bonds or director guarantees required by the landlord.
- Compliance with lease formalities: Some leases prescribe a specific form of deed or execution requirements. Ensure these are followed.
It’s common to pair the deed with a landlord’s consent letter. If you need legal guidance on drafting or negotiating these terms, a Commercial Lease Lawyer can act for you across the process.
Retail leases: disclosure and timing
If your lease is a “retail shop lease,” additional rules often apply. Most states and territories require certain disclosure documents to be exchanged on assignment, and they may affect timing and enforceability. For example, in New South Wales, the Retail Leases Act sets out disclosure obligations and consent processes for retail shop lease assignments.
Across Australia, disclosure obligations vary by jurisdiction, but the general theme is that outgoing and incoming tenants need to exchange prescribed disclosure information, and landlords have their own disclosure duties. Failing to meet disclosure requirements can delay consent or lead to disputes later.
Who remains liable after assignment?
This is a key negotiation point. In some cases, an assignor remains secondarily liable (for example, if the assignee defaults) until the lease ends. In other cases, the deed expressly releases the assignor from all future obligations. The outcome depends on the lease terms, the landlord’s position, and any statutory rules that apply to the category of lease.
If you’re unsure where liability will sit after assignment, get the deed reviewed before you sign. Landlord consent may also be conditional on you providing additional security or guarantees - factor this into your negotiations.
Compliance, Registration And Tax: What Should You Check?
Beyond the deed and consent, there are several compliance points to consider so your assignment is enforceable and properly recorded.
Titles registration (if the lease is registered)
For registered leases, most states require you to lodge the assignment with the relevant land titles office so public records reflect the new tenant. Registration forms and fees differ by jurisdiction. Your lease may also specify a timeframe for lodging assignment documents.
Retail leasing legislation
As noted, retail leases attract extra rules. These typically address disclosure, timeframes for landlord consent, costs that can be recovered, and what happens if disclosure isn’t properly given. The specific rules vary across states and territories, so check the retail leasing legislation that applies to your premises.
Taxes, duties and GST
- Stamp duty: Some jurisdictions may impose duty on assignments of long-term or registered leases (or particular associated instruments). Duty rules change and are state-based, so confirm your current position locally.
- GST: Assignments connected to a business sale can have GST implications (for example, where a sale is treated as a GST-free supply of a going concern if the rules are met). The GST outcome depends on your specific transaction.
Tax outcomes are fact-specific. You should seek advice from your tax adviser or accountant to confirm any stamp duty or GST position before completion.
Privacy and data transfers in a sale
If the lease assignment forms part of a business sale involving customer or employee data, ensure your transfer of personal information aligns with Australian privacy rules. In practice, having a clear, current Privacy Policy and appropriate consents or notices can help manage that risk.
What Documents Are Typically Involved?
The core documents usually include:
- Deed of Assignment of Lease: The primary instrument that transfers the lease to the assignee and sets out liability, security and timing. Consider engaging a Deed of Assignment of Lease lawyer to draft or review this.
- Landlord’s consent: Either embedded in the deed or signed as a separate consent letter, confirming approval of the assignment (and any conditions).
- Guarantees and security: New or replacement personal guarantees, bank guarantees or bonds, if required under the lease or by the landlord.
- Retail lease disclosure: Prescribed disclosure statements for outgoing and incoming tenants (and any landlord disclosure) where the lease is a retail shop lease.
- Titles office forms: Assignment and any supporting forms for lodgement if the lease is registered.
Where the assignment occurs alongside a business sale, you’ll also commonly see:
- Business Sale Agreement: Records the transfer of assets (including the lease assignment as a condition), price, warranties and completion steps. If you’re selling or buying, consider a reviewed Business Sale Agreement and, if needed, a Legal Due Diligence Package.
- Assignment or transfer of other assets: For plant and equipment, IP, domain names, licences and other operational assets that sit outside the lease.
If your lease has specific formalities (for example, a prescribed deed format or execution requirements), make sure those are followed exactly - otherwise consent or registration may be delayed.
Step-By-Step: How To Assign A Commercial Lease
Every lease is different, but this general process will help you stay on track and avoid common pitfalls.
1) Review the lease and plan timing
- Confirm you have the right to assign (and any restrictions or conditions).
- Note any required notice periods, fees and who bears legal costs.
- Check whether the lease is retail and whether statutory disclosure applies.
At this stage, it’s wise to get an early view from a Lease Review lawyer on consent conditions, disclosure obligations and continuing liability.
2) Identify a suitable assignee
- Gather information landlords usually request: financial statements, references, business plan and any director guarantees.
- Ensure the proposed use aligns with permitted use and any centre rules.
3) Apply for landlord consent
- Make a formal request and provide the landlord with all information they reasonably need to assess the assignee.
- Respond promptly to follow-up questions to keep timing on track.
4) Prepare the deed and related documents
- Draft the deed of assignment with clear allocation of liabilities, the effective date and any security or guarantees.
- Prepare or obtain any required disclosure statements for retail leases.
- Line up titles office forms if the lease is registered.
5) Execute and complete
- Arrange signing by the assignor, assignee, landlord and any guarantors as required.
- Complete handover items: keys, access cards, insurance confirmations, bank guarantees or bonds.
- Address make-good or repairs as agreed (or hold-backs if applicable).
6) Register (if required) and update records
- Lodge the assignment with the relevant land titles office for registered leases.
- Update landlord records for rent invoicing, outgoings, and building access.
If the assignment forms part of a business sale, coordinate timing with the broader completion checklist (asset transfers, employee transfers, stocktake and settlement funds). Sprintlaw can support with the property documents as well as the sale documentation so everything lines up on completion day.
Common Pitfalls (And How To Avoid Them)
- Skipping consent: Assigning without written consent (where the lease requires it) can trigger breach and leave you liable. Always obtain formal consent.
- Unclear liability allocation: If the deed doesn’t clearly state who pays existing arrears or handles make-good, disputes can erupt later. Spell this out.
- Assuming you’re released: Don’t assume your liability ends on assignment - get it confirmed in the deed and check what the lease and any applicable legislation say.
- Missing retail disclosure: For retail premises, prescribed disclosure is critical. Incomplete or late disclosure can delay consent or create legal risk.
- Forgetting registration: With registered leases, lodging the assignment protects the assignee’s position and avoids administrative headaches.
- Overlooking tax and duty: Duty and GST outcomes can vary. Confirm these with your accountant before you sign and settle.
If you’re already deep in negotiations and need help triaging issues, consider engaging a Commercial Lease Lawyer to negotiate conditions, fine-tune the deed, and coordinate landlord requirements.
Key Takeaways
- A deed of assignment of lease is the formal document that transfers your commercial lease to a new tenant and usually requires written landlord consent.
