Purchasing a business can be a smart way to fast‑track growth. You’re stepping into an existing customer base, systems, and revenue - without starting from scratch.
But buying a business is also a legal transaction with moving parts. The structure you choose, the contracts you sign, and the due diligence you complete will determine whether your deal is smooth and profitable - or risky and expensive.
In this guide, we’ll walk through the key legal steps to purchase a business in Australia, explain asset vs share sales in plain English, and highlight the documents and risks you need to cover before you sign.
Why Purchase A Business In Australia?
Buying an existing business can be attractive if you want a proven model with immediate cash flow. You can leverage the seller’s brand recognition, suppliers, and trained staff from day one.
At the same time, you need to look closely at what you’re really getting - and what you might be taking on. A clear plan and careful legal checks will help you avoid surprises.
Common reasons small business owners choose to purchase include:
- Speed to market - you can operate and earn income soon after completion.
- Established operations - systems, licences, and assets are already in place.
- Growth or diversification - bolt on a complementary service or enter a new region.
The trade‑offs include purchase price, potential hidden liabilities, integration challenges, and the need to renegotiate leases, supplier contracts, and employment arrangements. That’s why a legal roadmap is essential.
Asset Purchase Vs Share Purchase: Which Structure Suits You?
One of your first decisions is how to structure the deal. In Australia, most transactions are structured as either:
- Asset purchase: You buy specific assets of the business (for example, plant and equipment, stock, customer contracts, and IP) from the seller’s entity. You choose what you take and typically leave behind unwanted liabilities unless you agree to assume them.
- Share purchase: You buy the shares in the company that operates the business. The company (as a legal entity) stays the same - it keeps all its assets, contracts, employees, and liabilities - but you become the owner of that company.
Each option has different tax, risk, and practical implications. If you’re comparing both pathways, it helps to understand the main differences covered in Share Sale vs Asset Sale.
In simple terms, asset sales offer more control over what you acquire and what you leave behind. Share sales can be simpler operationally (you step into the owner’s seat of the existing entity) but require deeper due diligence on the company’s history and liabilities.
Step‑By‑Step: How To Purchase A Business Legally
1) Map Your Deal Strategy
Start with a clear picture of what you want to buy (assets or shares), your budget, your preferred timeline, and any key conditions (for example, landlord consent or key staff staying on). This gives you a reference point when negotiating heads of agreement and the main sale documents.
2) Sign a Confidentiality Agreement
Before the seller shares sensitive information, you’ll usually sign a Non‑Disclosure Agreement (NDA). This protects both parties and encourages open due diligence.
3) Heads of Agreement (Optional, But Helpful)
A short, preliminary document that outlines the commercial terms: purchase price, what’s included/excluded, proposed completion date, and key conditions. It’s often non‑binding except for confidentiality and exclusivity clauses, and sets expectations for the detailed contract.
4) Conduct Legal Due Diligence
Due diligence is your chance to verify what you’re buying. You’ll review financials, key contracts, licences, employment arrangements, IP, disputes, and regulatory compliance. Many buyers also run searches to confirm whether assets are free from security interests on the PPSR (Personal Property Securities Register). A comprehensive review like a Legal Due Diligence Package helps identify risks early and informs your negotiations.
5) Negotiate The Sale Agreement
The central contract is the asset sale agreement or share sale agreement. It sets out exactly what you’re buying, the price and adjustments, seller warranties, restraints of trade, completion mechanics, and what happens if something goes wrong. From a buyer perspective, getting a Business Sale Agreement Review helps strengthen your position and ensure protections are fit for purpose.
6) Secure Third‑Party Consents
Many deals depend on consents outside the seller’s control - for example, landlord consent to assign a shop lease, or a key supplier agreeing to novate their contract. Plan to obtain these before completion. If there’s a premises, you’ll likely need a Deed of Assignment of Lease or a new lease approved by the landlord.
7) Finalise Finance And Settlement Logistics
If you’re funding the purchase with bank finance, the lender will require documents and searches (and often conditions precedent) before drawdown. You’ll also agree practical completion steps - releasing funds, handing over keys and codes, transferring IP, and notifying staff and customers. Using a practical Completion Checklist helps keep settlement on track.
8) Completion And Post‑Completion Tasks
On completion day, the parties exchange signed documents, pay the price (subject to adjustments), and transfer the agreed assets or shares. Post‑completion, you’ll wrap up items like notifying ASIC for any ownership changes in a share deal, transferring licences, updating employee records, and replacing bank authorities.
What Legal Documents Will You Need?
Every transaction is different, but buyers commonly work with the following documents:
- Heads of Agreement/Term Sheet: Records the commercial terms while you finalise due diligence and long‑form documents.
- Asset Sale Agreement or Share Sale Agreement: The main contract that sets out price, inclusions/exclusions, warranties, indemnities, restraints, and completion process.
- Disclosure Letter: The seller’s formal disclosures against warranties (to qualify or limit their warranty liability).
- Deed of Assignment/Novation: Transfers key third‑party contracts, supplier agreements, or customer contracts to you (or to your entity).
- Deed of Assignment of Lease or New Lease: Transfers the premises or secures a new tenancy on acceptable terms.
- IP Assignment/Trade Mark Transfer: Assigns brand assets, domain names, and registered IP to your ownership.
- Employment Transfer Documents: Records the transfer or re‑hire of staff, including recognition of service where agreed.
- Share Transfer Forms (Share Sale): Transfers shares to you and updates the company’s register; ASIC filings may be required.
For buyers who want an end‑to‑end process guided by a lawyer, a tailored Business Purchase Package can coordinate these documents and the required steps from negotiation to completion.
Key Legal Risks To Check Before You Commit
Robust due diligence is your best risk management tool. Focus on these areas as a priority:
Contracts And Customer Relationships
- Transferability: Do key supplier, distributor, and customer contracts allow assignment or novation? Some contracts prohibit transfer without consent - which could impact revenue on day one.
- Change of Control: In a share sale, check for clauses that allow termination if the company’s ownership changes.
Leases And Property
- Lease terms: Confirm rent, options, outgoings, make‑good obligations, permitted use, and any arrears or disputes.
- Consent and timing: Landlord consent can take time. Build this into your conditions precedent and completion plan.
Employees And Employment Liabilities
- Who transfers: Identify key staff and agree whether you will recognise prior service for entitlements (this affects your accrued leave liabilities and onboarding).
- Contracts and awards: Review employment contracts, classifications under any modern awards, and any ongoing disputes or claims.
Intellectual Property And Brand
- Ownership: Verify that registered trade marks, website domains, and other IP actually belong to the seller and are free to transfer.
- Licences and third‑party tools: Check software and content licences used in the business are transferable or can be re‑issued to you.
Regulatory Compliance And Disputes
- Licences: Confirm all required licences or permits are current and can be transferred or re‑issued in your name.
- ACL and privacy: Review marketing and customer policies for compliance with the Australian Consumer Law and the Privacy Act, particularly around refunds, advertising, and data handling.
- Claims: Ask for details of any disputes, complaints, or investigations (and assess the likely exposure if they carry forward).
Financial Health And Security Interests
- Encumbrances: Search the PPSR for security interests over assets you’re buying, and ensure they’re released at or before completion.
- Working capital: Review cashflow, aged receivables/payables, and seasonality so you understand the working capital needs post‑purchase.
If you’re buying shares, go deeper on the company’s historical liabilities, tax compliance, superannuation payments, and any guarantees the company has given. You’ll also need to plan for notifying ASIC and managing the mechanics of transferring shares in a private company.
Common Conditions Precedent (Buyer‑Friendly Protections)
- Completion is conditional on satisfactory due diligence results.
- Landlord and key third‑party consents obtained in form acceptable to you.
- Release of PPSR security interests over purchased assets.
- Finance approval (if required) on terms acceptable to you.
- Seller compliance with restraint and handover obligations.
Restraints Of Trade
It’s common to include restraints preventing the seller (and key individuals) from competing, poaching staff, or soliciting customers for a defined time and area. Enforceability depends on reasonableness, so careful drafting matters.
Warranties And Indemnities
Warranties are promises about the state of the business (for example, that accounts are accurate, taxes are paid, and there are no undisclosed disputes). Indemnities allocate risk if a warranty is untrue or a specific liability arises. Negotiate these carefully and ensure you understand any limits (time caps, financial caps, and required notification steps).
Frequently Asked Questions About The Purchase Process
What’s The Difference Between Buying Assets And Buying Shares?
In an asset purchase, you pick and choose which assets and contracts you acquire, and you typically avoid legacy liabilities unless you agree to assume them. In a share purchase, you acquire the company that runs the business - so you inherit all assets and liabilities of that entity. The right choice depends on your risk tolerance, tax advice, and practical considerations like licences and contract transferability.
How Long Does It Take To Purchase A Business?
Smaller transactions can complete in 4-8 weeks, assuming fast access to information, prompt consents, and a straightforward business model. Complex or regulated businesses, multiple premises, or slow third‑party approvals can extend timelines. Build buffer into your plan.
Do I Need A Lawyer To Buy A Business?
You can negotiate commercial terms yourself, but legal due diligence, contract drafting, assignments/novations, and completion logistics are where a lawyer adds significant value and risk protection. Many buyers opt for a managed process so they don’t miss critical steps or inherit avoidable liabilities.
What If I’m Buying A Company (Share Sale)?
You’ll focus on company‑level risks: corporate records, historical liabilities, tax and super compliance, guarantees, and any change of control issues in key contracts. The mechanics include share transfer documents and company register updates; you can read more about the process in our guide to transferring shares in a private company.
Should I Search The PPSR?
Yes. If you’re purchasing assets like vehicles, equipment, or stock, check for registered security interests. You’ll want those interests released by completion so you receive clear title - see our explainer on what the PPSR is and why it matters.
Practical Tips To Strengthen Your Position
- Be specific about what you’re buying: List included assets and IP in schedules. If something’s important (like a domain name or social media handle), make sure it’s expressly covered.
- Confirm transferability early: Ask for copies of leases and key contracts and confirm whether assignment or novation is permitted. If not, line up workable alternatives.
- Map handover and training: Build a short transition period where the seller supports you post‑completion to ensure continuity with staff, systems, and customers.
- Use conditions precedent: Make completion contingent on due diligence, finance, consents, and PPSR releases so you can walk away or renegotiate if issues arise.
- Choose the right structure: If you’re undecided, revisit the differences in asset vs share sales and speak with your tax adviser for structuring advice.
- Plan your completion day: Align funds flow, signatures, and practical handover using a clear completion checklist.
Key Takeaways
- Purchasing a business can accelerate growth, but you need a clear legal plan covering structure, contracts, and risk management.
- Decide early between an asset purchase and a share purchase - each has different risk, tax, and operational implications.
- Strong due diligence (including PPSR searches) and buyer‑friendly conditions precedent help you avoid inheriting hidden liabilities.
- Get the right documents in place - from the sale agreement to assignments, lease transfer, IP assignment, and employment transfer records.
- Third‑party consents (landlord, key suppliers) and practical handover steps should be mapped well before completion.
- A managed process - from a due diligence review to the main documents via a Business Purchase Package - reduces risk and saves time.
