Selling a Business in Australia: Legal Checklist for Business Owners

Selling your business is a big milestone. It can open up the next chapter in your life, unlock capital and reward years of hard work. It can also feel complex, fast-moving and full of paperwork.

The good news? With the right preparation and a clear legal checklist, you can sell with confidence, protect your interests and avoid last-minute surprises.

Below, we walk you through how business sales work in Australia, the key steps to prepare, the documents you’ll need and the common pitfalls to avoid - whether you’re selling a local retail shop, a professional services firm or a growing ecommerce brand.

As always, we’re here to help if you want tailored advice for your situation.

What Does Selling a Business Involve?

At a high level, a business sale is the transfer of ownership from a seller to a buyer for an agreed price. In Australia, this typically happens in one of two ways:

• Asset sale: You sell the business’ assets (for example, goodwill, stock, equipment, domain names, trade marks and the lease). The legal entity that owns the business stays with you.
• Share sale: You sell some or all of the shares in the company that operates the business. The buyer takes over the company “as is” - including its assets, contracts and liabilities.

Most small-to-medium business exits use an asset sale. Share sales are more common where the buyer wants the company’s existing contracts, licences and history to stay intact.

If you’re weighing up the pros and cons of each pathway - including risk, tax and complexity - it’s worth comparing an asset sale vs share sale before you proceed.

Important: Australian Business Numbers (ABNs) and Australian Company Numbers (ACNs) do not transfer to a buyer. An ABN stays with the entity that registered it. An ACN stays with the company. What you can transfer are business assets (including a registered business name) in an asset sale, or the company’s shares in a share sale.

Plan And Prepare Before You List

Preparation can make a huge difference to price, speed and buyer confidence. Before you go to market, work through these essentials:

• Update financials: Buyers will want recent profit and loss statements, balance sheets, BAS and tax returns (usually for 2–3 years).
• Organise your contracts: Gather customer, supplier, software and landlord agreements, and note any consent needed to assign or novate them.
• Map assets and liabilities: Create a clear schedule of what’s included in the sale (stock, equipment, IP, domain names, social media, lease, data) and the liabilities you’ll retain.
• Check compliance: Confirm registrations, licences, insurance and key policies are current - especially privacy and Australian Consumer Law obligations if you sell online.
• Resolve issues early: If there are disputes, unpaid super or outstanding compliance items, tidy these up now. It makes due diligence faster and reduces price chips.

You’ll also want to think about tax impacts (for example, capital gains tax, GST on the sale of certain assets, or stamp duty in some states for certain transfers). These depend on your structure and the deal terms, so it’s wise to get independent tax advice alongside your legal preparation.

Legal Checklist: From Heads Of Terms To Settlement

1) Choose Your Sale Structure (Asset vs Share)

Decide early whether you’re selling assets or shares. It affects the timeline, the level of risk you keep, how warranties are framed and who needs to consent to transfers (for example, landlords and key suppliers). It also influences tax outcomes, so speak with your accountant or tax adviser while you’re at this stage.

2) Prepare For Buyer Due Diligence

Expect buyers to review your business thoroughly before they commit. Make it easy by setting up a secure folder (or data room) with:

• Financial statements, BAS and tax returns (2–3 years)
• Material contracts (customers, suppliers, software, distribution and lease)
• Company or business registration details, insurance and key policies
• Intellectual property records (trade marks, designs, domain ownership)
• Employment details (roles, contracts, entitlements, compliance records)
• Privacy and website policies, especially if you collect customer data

Clean, consistent records build trust and speed up the transaction.

3) Negotiate The Commercial Terms

Most deals start with a term sheet or heads of agreement. Keep it high level, non-binding (except for confidentiality and exclusivity if agreed) and focused on the core items:

• Purchase price and how it’s paid (upfront, instalments, earn-out)
• What’s included/excluded (assets, stock valuation, WIP)
• Timing (target completion date, key conditions precedent)
• Restraint period and scope (non-compete and non-solicit)
• Handover support (how long you’ll assist post-settlement)

If part of the price will be paid over time, set out the mechanics carefully. Where the seller funds part of the purchase, a dedicated vendor finance agreement can document interest, security and default rights.

4) Put The Sale Contract In Place

The contract is the backbone of your deal. In an asset sale you’ll usually use a Business Sale Agreement; in a share sale you’ll use a Share Sale Agreement. This document should clearly cover:

• Assets and liabilities: A precise list of what’s being sold and what’s retained.
• Price and adjustments: Stock, prepayments, employee entitlements and apportionments at completion.
• Conditions precedent: Third‑party consents, finance approval, regulatory approvals.
• Warranties and indemnities: Statements you’re making about the business, and what happens if they’re untrue.
• Restraints: Non‑compete and non‑solicit clauses to protect goodwill.
• Handover: Transition assistance, access, training and cooperation after completion.

Have an experienced lawyer draft or review your Business Sale Agreement so it reflects your business, manages risk and aligns with the negotiated terms.

5) Transfer Licences, Registrations And Names (What Does And Doesn’t Transfer)

Confirm what can be assigned and what needs a fresh application. Common examples:

• Business names: Can be transferred to the buyer in an asset sale.
• ABN/ACN: Do not transfer. The ABN stays with the entity; the ACN stays with the company. In a share sale, the company (and its ACN) continues under new ownership.
• Industry licences and permits: Some can be transferred with regulator consent; others require the buyer to apply anew.
• Domain names and social accounts: Transfer ownership with the registrar/platform and update billing and admin details.

Make these obligations explicit in the contract and allocate responsibility so nothing falls through the cracks.

6) Assign Or Novate Key Contracts (Including The Lease)

Customer agreements, supplier contracts, software licences and (crucially) the premises lease rarely move automatically to the buyer in an asset sale. You’ll typically need counterparties’ consent to assign, or a formal novation if the entire contracting party is changing.

For leases, a landlord’s written consent is almost always required. A dedicated deed of assignment of lease documents the transfer and any conditions (for example, a bond top‑up or personal guarantees). Build the consent process and timing into your deal timeline so settlement isn’t delayed.

7) Manage Employees And Entitlements

Work out early how staff will be handled. Options include transferring employees to the buyer (with recognition of service), keeping some with you or ending employment before settlement. Consider:

• How accrued leave and other entitlements will be treated at completion
• Who pays out unused leave or long service leave (by agreement and as required by law)
• New employment contracts to be issued by the buyer after completion
• Notice and consultation obligations under the Fair Work framework

Plan this carefully and communicate clearly with your team to minimise disruption.

8) Settle Smoothly With A Practical Handover

On completion, you’ll exchange signed documents, receive the balance of the purchase price and hand over the business. A practical checklist helps the day run smoothly, including keys, passwords, POS access, bank merchant facilities, domain transfers, website admin access, social logins and key supplier handovers. A simple completion checklist can keep everyone aligned.

9) Stay On Top Of Consumer Law And Advertising

Even as you transition out, make sure your business practices remain compliant. Misleading or deceptive conduct is prohibited under the Australian Consumer Law. Keep advertising, pricing and representations accurate, and ensure customer remedies are handled properly. Section 18 of the ACL is a helpful touchpoint for these obligations - see this overview of misleading or deceptive conduct.

Thinking Of Buying A Business Instead?

If you’re on the other side of the table, your priorities are due diligence, clear warranties and making sure critical assets (like the lease, IP and data) can be transferred. Check that the seller actually owns what they’re selling, confirm there are no undisclosed liabilities and ensure restraints and handover support meet your needs. Getting legal support early can surface issues before they become deal‑breakers.

The Core Documents In A Business Sale

Every deal is different, but most business sales involve some or all of the following documents:

• Heads of Agreement/Term Sheet: A short, mostly non‑binding outline of key terms to guide the formal documents.
• Business Sale Agreement or Share Sale Agreement: The main contract setting out price, assets, liabilities, conditions, warranties, restraints and completion mechanics.
• Disclosure letter or annexures: Details of exceptions to warranties, known issues and specific risks so both parties are clear.
• Deeds of assignment/novation: Transfers of key contracts (for example, supply agreements, software licences or the premises lease).
• IP assignment documents: Transfers of trade marks, domain names, copyright and other IP.
• Employment letters: Termination, transfer or offer letters to manage employees’ transition.
• Restraint deed (if separate): Non‑compete and non‑solicit obligations where these sit outside the main agreement.
• Vendor finance or security documents (if applicable): Where payment is staged or secured over assets or shares.

This is also a good moment to tighten your brand protection. If your brand name or logo is a big part of the business’ value, ensure your registrations are up to date so they transfer cleanly. Many sellers and buyers formalise this via a trade mark assignment at completion - or register/renew beforehand using trade mark support.

Online And Ecommerce Sales: Extra Steps To Get Right

If you’re selling an online store or platform-based business, the core legal steps still apply - but digital assets and data handling need special attention.

Digital Assets And Access

• Domains and hosting: Transfer the domain name ownership and update registrant details, DNS settings and billing.
• Website and code: Assign the website, theme licences and any custom code. Make sure any third‑party developer agreements allow assignment.
• Platform accounts: For Shopify, Amazon, eBay or app stores, check platform rules on transfer and ensure payouts and tax/billing info switch to the buyer on completion.
• Social media: Hand over admin control and ownership of business pages and ad accounts.

Customer Data, Privacy And Email Lists

If you’re handing over customer databases or email lists, privacy compliance is essential. Be clear about how personal information has been collected and used, and make sure your policies match your actual practices. Ensure the buyer understands the ongoing obligations and updates public-facing policies promptly after settlement.

Most online businesses will need a current Privacy Policy that sets out how personal information is handled. Update it as part of the transition so customers know who their data controller is after the sale.

Advertising, Claims And Reviews

As you approach completion, ensure product pages, claims and promotions remain accurate and compliant. Avoid any last-minute changes that could create misleading impressions or complaints under the ACL.

Supply Chain And Logistics

For drop‑shipping or third‑party logistics models, check assignment rights in supplier and fulfilment contracts. If consents are needed, build those into your conditions precedent and timeline so the buyer can keep trading from day one.

Key Takeaways

• Decide early whether your sale will be an asset sale or a share sale - it affects risk, tax, timing and the documents you’ll use.
• Preparation pays off: tidy financials, organise contracts, map assets and resolve issues so buyer due diligence runs smoothly.
• Get your contract right: a tailored Business Sale Agreement should clearly cover assets, price, adjustments, conditions, warranties, restraints and handover.
• Know what transfers and what doesn’t: business names, assets and leases can be assigned (with consent), but ABNs and ACNs don’t transfer; in a share sale the company continues under its ACN.
• Secure key approvals: landlord consent, supplier consents and any regulator approvals are critical to build into your timeline and conditions precedent - a lease assignment deed is common.
• Protect digital value: for online businesses, document transfers of domains, platforms, social accounts and customer data, keep your Privacy Policy current and avoid ACL issues like misleading claims under section 18.
• Plan settlement carefully: use a practical handover list so payments, access, passwords and IP transfers are all ticked off - a simple completion checklist helps.
