When you’re negotiating a deal, the words “we promise” don’t always cut it. If you want a promise to carry legal weight, a deed of warranty is one of the strongest tools you can use to lock in assurances and manage risk.
Whether you’re selling a business, transferring shares, onboarding a key supplier, or handing over intellectual property, a deed of warranty can give both sides confidence that important statements are true and enforceable.
In this guide, we’ll explain what a deed of warranty is in Australian law, when a small business should consider using one, what to include, and how to execute it properly so it stands up if something goes wrong.
What Is A Deed Of Warranty?
A deed of warranty is a formal legal document in which a party gives legally binding warranties (promises) about specific facts or circumstances. Unlike a standard contract, deeds do not require “consideration” (payment or value exchange) to be enforceable. That’s one reason they’re often used to deliver robust, enforceable promises in high‑value or high‑risk transactions.
If you’re new to deeds generally, it’s worth understanding the differences between deeds and agreements, execution formalities, and why businesses choose deeds over contracts. A quick refresher on What Is a Deed can help set the scene.
In practice, a “deed of warranty” records warranties and related terms like limits, timeframes, indemnities, and claim procedures. It can be a standalone deed or built into another deal document (for example, warranties inside a business sale agreement).
When Should A Small Business Use A Deed Of Warranty?
You’ll most often see deeds of warranty used when a buyer or counterparty needs strong comfort that key facts are accurate. Common scenarios include:
1) Selling Your Business Or Major Assets
Buyers typically ask sellers to warrant things like ownership of assets, no undisclosed liabilities, up-to-date tax compliance, accurate financials, valid contracts, and compliance with laws. These can sit inside a Business Sale Agreement or be documented in a separate deed of warranty that survives completion.
If you’re deciding how to structure the deal, the set of warranties can differ between a Share Sale vs Asset Sale, so the deed needs to match the transaction type.
2) Share Sales And Investment Rounds
Founders may give warranties to investors about cap tables, IP ownership, current litigation, and compliance. A deed format can help those promises remain enforceable after completion and for agreed “limitation periods.”
3) IP Assignments And Technology Deals
When transferring IP, the receiving party often wants warranties that the assignor owns the IP, has the right to assign, and that the IP doesn’t infringe others’ rights. A deed of warranty can also include indemnities if those statements prove false.
4) Supplier And Distribution Arrangements
Where product quality, safety, origin, or compliance matters, the receiving party may seek warranties that goods meet standards, are genuine, and comply with applicable laws (for example, labelling and safety regimes).
5) Settlements And Risk Allocation
Deeds resolving disputes sometimes include warranties (for example, each party warrants they have authority to sign and there are no additional claims being kept back). If you’re formalising a resolution, a dedicated Deed of Release and Settlement may be the right vehicle, with warranties built in.
In short: use a deed of warranty when you need durable, enforceable promises to support a transaction or manage risk. The higher the stakes, the more important it is to get the warranties right.
What Should A Deed Of Warranty Include?
The exact content depends on the deal. However, most deeds of warranty for small businesses will cover the following areas.
Core Warranties (Tailored To The Deal)
- Ownership and title: The warrantor owns the assets or shares free from third-party rights (no liens, charges, security interests).
- Authority and capacity: The party has authority to enter into the deed and perform obligations (often relevant where boards or shareholders must approve).
- No undisclosed liabilities: There are no liabilities or adverse matters other than those disclosed (for example, in a disclosure letter or schedule).
- Financial statements: Accounts are true, fair, and prepared in accordance with applicable standards.
- Tax: Tax filings are up to date, tax has been paid, and there are no ongoing tax disputes.
- Contracts: Material contracts are valid, enforceable, and assignable; no defaults exist or are anticipated.
- IP and data: The business owns or validly licenses IP it uses; no infringement claims are threatened; data and privacy compliance is in place.
- Employment: Employment obligations are met; no outstanding claims, underpayments, or misclassification issues.
- Regulatory compliance: Licences and permits are valid; the business complies with relevant industry laws and the Australian Consumer Law (ACL).
Limits, Carve-Outs And Timeframes
- Financial caps: A cap on total liability for warranty claims (for example, capped at a percentage of the purchase price).
- De minimis thresholds: Small claims are ignored until a minimum amount is reached.
- Time limits: Warranty claims must be notified within a set period (for example, 12-24 months, with longer for tax or title warranties).
- Knowledge qualifiers: Warranties given to the best of the warrantor’s knowledge (define whose knowledge counts and what “knowledge” means).
- Disclosures: A schedule that lists exceptions so the warrantor is not liable for disclosed issues (this is often called a disclosure letter or schedule).
Indemnities And Remedies
Deeds commonly include an indemnity if a warranty is untrue, allowing the claiming party to recover losses on an indemnity basis. The deed can also deal with how claims are notified, investigation rights, and how losses are calculated (for example, excluding double counting or consequential loss if that’s agreed).
Claim Process
- Notice: What a claim notice must include and how it must be served.
- Mitigation and cooperation: Requiring reasonable steps to reduce loss and cooperate with the warrantor’s investigation.
- Third-party claims: Who controls defence and settlement of third‑party claims and how costs are handled.
Execution And Formalities
Because it’s a deed, execution formalities matter. Include signature blocks that comply with company signing rules and any witnessing requirements (more on this below).
Finally, keep in mind a deed of warranty is not the same as an ACL “warranty against defects” provided to consumers about goods and services. If you sell to consumers, you may separately need a Warranties Against Defects policy that complies with the ACL’s mandatory wording and disclosure rules.
How Do You Execute A Deed Of Warranty Correctly?
Deeds must meet certain formalities to be enforceable, which can differ by state and by entity type. Getting execution wrong is a common and costly mistake-so take care with the basics.
Execution As A Company
Under the Corporations Act, companies have a statutory shortcut for validly executing documents (including deeds) by two directors, a director and company secretary, or a sole director if they’re also the sole company secretary. This is often referred to as signing under section 127. If you follow section 127, counterparties can rely on your execution without digging into your internal authorisations.
Execution By Individuals, Trustees Or Partnerships
Individuals may need to sign in the presence of an independent witness (requirements vary by state). If a trustee company or individual trustee is signing, make sure the deed states the capacity (e.g. “as trustee for the XYZ Trust”). If a partnership is involved, confirm who has authority to bind the partnership.
Remote Signing And Counterparts
Most deeds now allow for electronic execution and signing in counterparts, but you should confirm what’s permitted in your state and in the deed itself. It’s common to include a counterparts clause and an electronic execution clause to avoid doubt.
Other Formalities To Check
- Witnessing: If witnessing is required, ensure the witness details are complete and the witness is eligible.
- Delivery: Deeds typically take effect on “delivery” (which can be defined in the deed). Include a simple delivery clause.
- Authority: If your board or shareholders need to approve the deed, record that approval (e.g. via resolutions) before signing.

Common Risks, Limits And Negotiation Tips
Warranties are rarely “take it or leave it.” Expect to negotiate scope, qualifiers, and remedies. Here are practical tips to protect your business.
If You’re Giving Warranties (Seller/Provider)
- Disclose, disclose, disclose: Comprehensive disclosure schedules are your best defence. If it’s disclosed, it’s usually carved out from liability.
- Use sensible qualifiers: Qualify appropriate warranties by knowledge, materiality, or “so far as reasonably practicable.” Define these terms clearly.
- Set fair caps and time limits: Caps tied to deal value and commercially standard claim periods keep risk manageable (with longer periods for title and tax).
- Avoid absolute statements you can’t verify: For example, “no breach of any law” is too broad-narrow it to material breaches or your actual operations.
- Coordinate with insurance: If you carry professional indemnity, product liability, or warranty and indemnity (W&I) insurance, ensure terms don’t jeopardise cover.
If You’re Receiving Warranties (Buyer/Customer)
- Identify what matters most: Prioritise warranties that protect the deal’s value-title, IP, financials, key contracts, and compliance.
- Avoid over‑narrow qualifiers: “To the best of knowledge” may be acceptable if “knowledge” includes reasonable inquiries and named individuals.
- Push for appropriate remedies: Indemnities for critical warranties, reasonable claim periods, and practical claim processes.
- Preserve overlapping rights: Make clear the deed’s remedies are in addition to statutory rights under the ACL for consumers and small businesses, where relevant.
Make The Document Work With The Deal
Often your deed of warranty sits alongside the main deal document-such as a sale agreement, IP assignment, or services agreement. Ensure definitions, timelines, and dispute mechanisms line up across the suite so there are no gaps or conflicts.
For full business divestments, warranties can live inside the main Business Sale Agreement or be separated into a deed that continues for a set period post‑completion. If you’re weighing deal structures, the mix of warranties you need will differ in a Share Sale vs Asset Sale.
Alternatives And Related Deeds
Not every situation calls for a deed of warranty. If you’re settling a dispute or finalising a handover with mutual releases, a targeted Deed of Release and Settlement might be more appropriate. In some simple one‑party promise scenarios, a unilateral deed (a deed poll) can be used; its structure is different from a bilateral deed of warranty, but it can achieve a similar outcome when only one party gives binding promises.
Step‑By‑Step: How To Prepare Your Deed Of Warranty
1) Map The Risks And What You Need To Prove
List the facts that, if wrong, would materially harm you (or your buyer/customer). Those are prime candidates for warranties. Keep it outcome‑focused: what do you need to be true on completion and during any warranty period?
2) Draft Clear, Tailored Warranties
Use plain English, avoid ambiguity, and tie warranties to specific assets, dates, and documents. If you’re reusing templates, adjust for the industry, jurisdiction, and deal structure-generic warranties can create false comfort.
3) Add The Risk Controls
Agree caps, time limits, thresholds, knowledge qualifiers, and carve‑outs that fit the deal size and risk. For tax, title, and fundamental warranties, different caps and longer periods are common.
4) Decide On Disclosure Mechanics
Choose how disclosures will be made (schedule vs separate disclosure letter), what level of detail is required, and how disclosed matters interact with warranties and indemnities.
5) Align With The Main Deal Documents
Cross‑check definitions (for example, “Claim,” “Loss,” “Tax”), completion mechanics, governing law, and dispute clauses. Make sure claim processes in the deed don’t conflict with time bars or procedures in the main agreement.
6) Execute Properly
Confirm signatories, witnessing (if required), and delivery. Where possible, use company execution under the Corporations Act’s section 127 for certainty. Build in a counterparts and electronic execution clause so you’re not chasing wet‑ink signatures unnecessarily.
7) Keep Evidence And Diarise Time Limits
Store the signed deed and all disclosure materials securely. Diarise claim periods and any notification deadlines so you don’t miss your rights.
Deed Of Warranty vs Consumer Warranties: What’s The Difference?
It’s easy to confuse a deed of warranty with consumer‑facing warranties about the quality of goods and services. They’re different tools for different jobs:
- Deed of warranty: A business‑to‑business risk allocation tool tied to a specific transaction or relationship. It’s negotiated, tailored, and enforceable as a deed.
- Consumer warranties: Statements you make to end customers about your products/services, which must comply with the Australian Consumer Law. If you offer a warranty against defects, you’ll need compliant wording and disclosures, often documented in a Warranties Against Defects document.
You can use both: for example, in a wholesale supply agreement with a retailer you might provide a deed of warranty about your ability to supply and compliance, while also offering ACL‑compliant warranties to end consumers on the products themselves.
Frequently Asked Questions
Is a deed of warranty enforceable without payment?
Yes. One of the hallmark features of a deed is that it’s enforceable without consideration. That’s why deeds are preferred for certain promises, especially where there isn’t a traditional payment exchange for the warranty itself.
How long do warranties last?
It’s up to the parties. Commonly, claims must be brought within 12-24 months after completion, with longer for tax and title warranties (sometimes up to 7 years, depending on the risk profile and negotiation).
Can we limit the warrantor’s liability?
Yes. Commercially standard limits include caps, baskets (de minimis and aggregate thresholds), time limits, and exclusions of certain types of loss. The deed should set out the limits clearly.
Do deeds have to be witnessed?
Witnessing requirements vary by state and by who is signing. Companies signing under section 127 generally don’t require witnessing, while individuals often do. Check the signing block and local rules, and follow the legal requirements for signing documents.
Key Takeaways
- A deed of warranty is a powerful way to secure enforceable promises in high‑value or high‑risk deals, without needing consideration.
- Use deeds of warranty in business sales, share sales, IP transfers, and key supply relationships where accuracy of facts really matters.
- Include tailored warranties, clear limits and timeframes, disclosure mechanics, indemnities, and a practical claim process.
- Execute correctly-company execution under section 127, correct witnessing for individuals, and counterpart/e‑sign clauses-to avoid enforceability issues.
- Keep deal‑level warranties separate from consumer‑facing ACL warranties; if you provide consumer warranties, maintain a compliant Warranties Against Defects policy.
- Align the deed with your main deal documents, whether it’s a Business Sale Agreement or a structure like a Share Sale vs Asset Sale, so definitions, timelines and remedies are consistent.
