Essential Legal Steps For Purchasing A Business In Australia

Buying an existing business in Australia can be an exciting shortcut into entrepreneurship or expansion. You’re stepping into something that already has customers, systems and revenue - but you’re also inheriting risks, contracts and legal obligations.

With the right plan and documents, you can reduce risk, protect your investment and make the transition smooth. This guide walks you through the essential legal steps for purchasing a business in Australia - from due diligence and contracts to compliance, taxes and handover.

What Does Purchasing A Business Involve?

When you purchase a business, you’re acquiring ownership of an existing operation. Practically, this happens in one of two ways:

• Asset purchase: You buy selected assets (for example, equipment, stock, intellectual property, goodwill, and sometimes the business name) and may take an assignment of the lease and key contracts.
• Share purchase: You buy the shares in the company that operates the business. The company keeps all its assets, contracts, employees and liabilities - you step into the owner’s shoes.

Asset purchases can offer cleaner risk allocation (you pick what you acquire). Share purchases can be faster and avoid retitling assets and contracts, but you inherit the company’s history, including liabilities you might not expect.

Either way, you’ll need to confirm what exactly you’re buying, how it will be transferred, and which risks you’re taking on. That’s where careful planning and legal due diligence come in.

Planning Your Purchase: Questions To Ask Early

Before you sign anything, get clear on viability and risk. A short planning checklist helps you spot issues early and frame your negotiations.

• Why is the business being sold? Retirement, strategic shifts and illness are different to declining sales or unresolved disputes.
• Financial health: Ask for management accounts, BAS, tax returns, debt schedules and aging reports for receivables and payables.
• Customers and contracts: Who are the key customers? Are major contracts assignable on a change of ownership?
• Premises: Is there a lease? What are the rent, options, outgoings and landlord consent requirements?
• People: Which employees will you retain, and on what terms? Are there outstanding entitlements or disputes?
• Assets and IP: What equipment, vehicles, software, trade marks, domains and social accounts are included? Are they owned outright or under finance?
• Compliance and reputation: Any investigations, fines, safety issues or negative reviews that may follow the brand?
• Deal structure: Will it be an asset or share purchase, and how will that affect risk, tax and stamp duty?

Capture your findings in a simple business plan and risk register. This makes negotiations more focused and aligns advisers (lawyer, accountant, lender) on what you’re solving for.

Step-By-Step Legal Process To Buy A Business

1) Do Legal Due Diligence

Due diligence is your deep dive into the business before you commit. It goes beyond the financials - you’re verifying ownership, risks and transferability of what you’re buying. A targeted scope usually includes:

• Company and title checks, PPSR searches and releases for financed assets.
• Financial records (tax returns, BAS, payroll and superannuation compliance, debt schedules).
• Key contracts (supplier, customer, distribution, franchise, finance, insurance) and whether they are assignable or need consent.
• Premises documents (lease, options, incentives, landlord consent process).
• Employment contracts, awards coverage, outstanding entitlements and any disputes.
• Intellectual property (trade marks, business names, domains, software licences) and proof of ownership.
• Regulatory approvals, licences and any investigations or litigation.

If you want a structured approach, consider a legal due diligence package so you know where the real risks sit.

2) Choose Your Buying Entity And Structure

Decide whether you’ll purchase as a sole trader, partnership or company. A company separates business risk from your personal assets and can make partnering and investment easier later on, while sole trader is simpler but risk sits with you. If you already have a holding company or trust structure, align the purchase with that plan.

If you’re buying with co-owners, agree decision-making rules, exits and profit splits upfront and document them (a Shareholders Agreement is common in company purchases).

3) Set Commercial Terms (Heads Of Agreement)

Before drafting the main contract, many buyers and sellers agree key terms in a short, non-binding Heads of Agreement or term sheet. This usually covers price, deposit, what’s included, whether it’s an asset or share sale, conditions (like finance, due diligence, landlord consent), restraints of trade and target settlement date.

4) Lock In A Robust Business Sale Agreement

The Business Sale Agreement is the core legal document. It should clearly list what you’re buying, the price and adjustments, how assets and contracts will transfer, seller promises (warranties), restraints and what happens if things go wrong. Getting this right reduces disputes and protects your position.

If you don’t have one yet, a tailored Business Sale Agreement focused on your deal structure and industry is essential.

5) Secure The Lease And Premises

Most small businesses hinge on the location. If you’re taking over a lease, you’ll likely need the landlord’s consent to an assignment, and you may need to provide guarantees or a bank guarantee. Some buyers negotiate a brand new lease instead.

Lease terms drive profitability (rent, reviews, outgoings, options), so plan time for landlord approvals and get a lease review before you’re locked in.

6) Transfer Employees Correctly

When retaining staff, you’ll need to deal with offers of employment, recognition of service (or not), and the transfer of entitlements like annual leave and personal leave depending on the deal structure. Ensure pay rates meet award or enterprise agreement obligations and that superannuation and payroll systems are set up before day one.

Issue each person a compliant Employment Contract reflecting their role, hours, probation and any restraints or IP protections you need.

7) Protect IP, Data And Brand

Confirm you can use the business name and brand, transfer domain names and social media handles, and get assignments for any copyright and designs. If brand protection matters, plan to register your trade mark early.

For confidential information shared before settlement, put a Non-Disclosure Agreement in place. If the business collects personal information, you’ll also need clear data-handling processes and a public-facing Privacy Policy where required (more on privacy law below).

8) Complete Settlement And Post-Settlement Tasks

On settlement, you’ll exchange funds and transfer assets. Typical completion items include lease assignment, business name transfer, IP assignments, PPSR releases and new registrations, handover of records, equipment and keys, and notifications to suppliers and customers.

Plan your first 30 days: update ABN and invoicing details, switch utilities and insurance, move payment gateways and POS, and set up payroll and superannuation. If you’re taking security over assets or vendor finance, lodge PPSR registrations promptly. A quick refresher on why the PPSR matters is here: PPSR in Australia.

Laws And Registrations To Keep You Compliant

Australian Consumer Law (ACL)

If you sell goods or services, you must comply with the Australian Consumer Law. This covers consumer guarantees, refunds, warranties against defects, fair contract terms and advertising. Factor these obligations into your customer terms and refund policies from day one.

Corporations And Directors’ Duties

If you’re buying shares or running the business through a company, you’ll take on directors’ duties and governance obligations under Australian company law (for example, keeping proper records, acting in the best interests of the company and avoiding insolvent trading). Update ASIC records for directors and shareholders after completion, keep your registers current and diarise annual obligations.

Employment Law

As the new employer, you’ll need to meet minimum pay, award coverage, leave entitlements and workplace health and safety obligations. Set up compliant employment contracts and policies, ensure correct superannuation and payroll tax are paid, and address any inherited performance or WHS issues early.

Privacy And Data

Most small businesses under the $3 million annual turnover threshold are not directly subject to the Privacy Act 1988 (Cth) unless an exception applies (for example, health service providers, businesses trading in personal information, or contractors to government). Even if the Act doesn’t apply, customers expect clear, transparent data practices - having a practical Privacy Policy and good data hygiene is a smart move and may be required by platforms you use.

Licences, Permits And Industry Rules

Many businesses need local council permits (signage, outdoor dining), food or health licences, liquor licences, or industry accreditations. Confirm what the business currently holds, whether licences can be transferred and what timelines and fees apply.

Franchising (If Applicable)

Buying or selling within a franchise system adds extra rules under the Franchising Code of Conduct, including disclosure documents, cooling-off rights and dispute processes. Review the franchise agreement carefully alongside your sale contract and budget time for franchisor consent.

Tax, Duty And Financial Checks To Factor In

Legal and tax issues go hand in hand in a business purchase. Build these into your deal structure and timelines, and involve an accountant alongside your lawyer.

• GST and going concern: Many business sales are structured as a GST-free “supply of a going concern” if certain criteria are met (including both parties being GST-registered and the business being supplied as a continuing enterprise). Your contract should deal with this and price adjustments.
• Stamp duty/transfer duty: States and territories have different rules and rates. Asset sales (especially of goodwill, land and some IP) can attract duty; share sales may also be dutiable in some jurisdictions. Confirm duty early so there are no surprises.
• Capital gains tax (CGT): CGT is typically a seller issue, but it affects negotiations, timing and price. Understand how proposed adjustments and earn-outs will be treated.
• Payroll tax and WorkCover: If your wages exceed state thresholds, register for payroll tax. Transfer or set up workers compensation insurance and ensure classifications are correct before day one.
• BAS, super and ATO lodgements: Confirm that BAS and superannuation are up to date, and deal with any ATO payment plans. Price adjustments often account for tax liabilities up to settlement.
• Apportionments and adjustments: The contract should set out how stock, deposits, gift cards, prepayments, rent, outgoings and utilities are adjusted between the parties at settlement.

Tax outcomes depend on your structure and the deal. It’s worth obtaining accountant advice in parallel with legal drafting so the contract reflects the intended tax treatment.

Key Contracts And Documents You’ll Likely Need

Every deal is different, but these documents commonly feature in Australian business purchases:

• Business Sale Agreement: Sets out exactly what you’re buying, the price and adjustments, seller warranties, restraints of trade, conditions precedent, risk allocation and settlement mechanics. A tailored Business Sale Agreement is your primary safeguard.
• Lease assignment or new lease: Landlord consent, assignment deeds and bank guarantees are often required. A lease review helps you understand rent reviews, options, make-good and personal guarantees.
• Employment agreements and policies: Use clear, compliant Employment Contracts and ensure awards, super and WHS are covered in your onboarding.
• Supplier and customer agreements: Assign or re-paper key relationships on terms that work for your new operation. Consider minimums, pricing, exclusivity and termination rights.
• Non-disclosure and restraints: A NDA protects confidential information during negotiations; post-sale restraints stop the seller from competing or soliciting staff and customers for a reasonable period.
• Intellectual property assignments and trade marks: Transfer ownership of logos, content and domains, and consider filing to register your trade mark so your brand is protected going forward.
• Privacy and data materials: Where required, publish a Privacy Policy and implement internal procedures for data collection, storage and access.
• PPSR releases and registrations: Arrange releases for the seller’s security interests over assets you’re buying and lodge new security interests if relevant (for example, vendor finance or equipment finance).

You won’t always need every document on this list, but most purchases require several of them. The key is to ensure each contract reflects your exact deal and the risks you’re willing to accept.

Key Takeaways

• Decide early whether you’re buying assets or shares - this choice drives risk, tax, duty and the documents you’ll need.
• Run targeted legal due diligence so you know what you’re really buying and which consents and transfers are required before settlement.
• Use a tailored, well-drafted sale contract with clear inclusions, warranties, restraints, adjustments, PPSR releases and settlement steps.
