Introduction
Buying or selling a business is a major commercial milestone, often involving significant financial stakes and long-term strategic implications. Whether the transaction involves the sale of business assets or the transfer of shares in a company, the legal complexities are considerable. As lawyers at Adamson Legal Group, we regularly advise business owners, investors, and corporate entities on navigating business and share sales in Australia with confidence, clarity, and commercial insight.
Business and share sales require much more than a handshake or a simple agreement. They involve careful planning, detailed due diligence, risk assessment, and precise documentation. Missteps—such as inadequate contract terms, overlooked liabilities, or poor structuring—can have costly and sometimes irreversible consequences. This article provides an in-depth look at the key legal considerations involved in business and share sales across Australia, and explains how legal advice can safeguard your interests.
Understanding the Difference: Business Sale vs Share Sale
One of the first decisions in any transaction is whether to structure the sale as an asset sale (sale of business) or a share sale.
Business/Asset Sale
In an asset sale, the buyer acquires specific assets of the business. These may include:
- Plant and equipment
- Intellectual property
- Customer lists and goodwill
- Stock
- Contracts and leases (subject to assignment)
The buyer does not automatically inherit liabilities unless these are expressly agreed to. This structure offers buyers greater control over the specific items they acquire and may reduce exposure to historical issues within the business.
Share Sale
In a share sale, the buyer acquires the company’s shares and therefore steps into the shoes of the existing owners. This means:
- All assets remain within the company
- All liabilities (past, present, and contingent) remain
- Contracts, employees, and licenses continue without the need for reassignment
Share sales can be simpler to implement contractually, but carry a higher risk, as the buyer inherits the entire corporate history. For this reason, extensive due diligence and strong warranties and indemnities are essential.
Due Diligence: The Foundation of a Safe Transaction
Due diligence is a critical investigative process that allows a party—usually the buyer—to examine the financial, legal, and operational aspects of the business or company. At Adamson Legal Group, we conduct and guide clients through comprehensive due diligence to identify risks and inform negotiations.
Key Due Diligence Areas
- Financial Review
A thorough analysis of financial statements, tax returns, BAS statements, and debt obligations helps verify profitability and financial sustainability.
- Legal Review
We examine:
- Company structure and corporate records
- Contracts with suppliers, customers, franchise networks, and distributors
- Lease agreements and property arrangements
- Licensing and regulatory compliance
- Intellectual property ownership
- Litigation history and disputes
A legal review uncovers issues that may impact value, operate as deal-breakers, or require contractual protections.
- Employment Matters
Employee entitlements, award compliance, employment agreements, and potential workplace claims must be verified. In share sales, the new owner automatically inherits all associated responsibilities.
- Operational and Commercial Factors
Buyers should understand how the business operates day-to-day:
- Key staff dependencies
- Supply chain stability
- Technology systems
- Customer concentration or risks of loss
Due diligence provides transparency and strengthens negotiating power.
The Contract: A Critical Negotiation Tool
The sale agreement is the core legal document governing the transaction. It must be clear, comprehensive, and drafted to reflect the precise commercial intentions of the parties.
Essential Contractual Elements
- Purchase Price and Adjustments
Price may include fixed components, stock adjustments, or earn-out mechanisms tied to future performance. Clear formulae are essential.
- Assets and Liabilities
In a business sale, the contract must accurately identify which assets and liabilities are included and which are excluded.
- Warranties and Indemnities
These clauses protect the buyer by requiring the seller to confirm key facts about the business and compensate the buyer if those statements prove false.
Examples include warranties about:
- Financial accuracy
- Tax compliance
- Ownership of assets
- Supplier and customer commitments
- Absence of undisclosed liabilities
Indemnities provide direct financial protection for specific risks identified in due diligence.
- Restraints of Trade
Sellers are often required to agree not to compete with the business for a defined period and within a reasonable geographic area. These clauses are crucial for maintaining the goodwill purchased.
- Transitional Support
Buyers may require the seller’s assistance for a period post-settlement to ensure continuity. This may be formalised through a consultancy or training clause.
- Settlement Conditions
Conditions precedent may include:
- Finance approval
- Assignment of leases
- Third-party consents (e.g., franchisors, licensors, landlords)
- Regulatory approvals
Failure to meet conditions may end the transaction.
Tax and Structuring Considerations
Tax implications differ significantly between asset and share sales. For example:
- Sellers may prefer share sales for potential access to capital gains tax (CGT) concessions.
- Buyers may prefer asset sales to step up the value of assets for depreciation purposes.
- GST treatment varies depending on whether the business is sold as a going concern.
Engaging accountants and tax specialists early ensures the structure is commercially and financially advantageous.
Settlement and Post-Completion Obligations
Settlement involves transferring funds, signing documents, transferring assets or shares, and meeting all outstanding conditions. For share sales, ASIC notifications and corporate registers must be updated.
After completion, buyers must ensure:
- New bank accounts are established
- Employees are onboarded and entitlements transferred where applicable
- Systems, passwords, and IP rights are transferred
- Customers and suppliers are notified
We assist clients in managing these tasks to ensure a smooth transition.
