Thinking about selling (or buying) shares in a private company? Whether you’re a founder planning an exit, a shareholder looking to cash out, or an investor stepping into ownership, a share sale is a pivotal moment that can shape your financial future.
It’s also different to a simple asset deal. With a share sale, you’re dealing with the ownership of the company itself - which means contracts, people and liabilities typically stay where they are. Getting the legal steps right helps you avoid disputes, stay compliant and achieve a clean handover.
Below, we break down the essential Australian legal steps for a sale of shares in a private company - from planning and due diligence through to contracts, completion and post-completion updates.
What Is a Share Sale (And How Is It Different to an Asset Sale)?
A sale of shares is the transfer of existing shares from one shareholder to another person or entity. The company remains the same legal entity before and after the deal, so its assets, liabilities, contracts and employees stay with the company.
This differs from an asset sale, where a buyer acquires selected business assets from the company rather than the shares in the company itself. In a share sale, the buyer steps into the existing structure, which can be simpler for continuity - but they also inherit the company’s risks (including hidden liabilities).
In Australia, most private-company share sales are documented in a Share Sale Agreement, supported by approvals, resolutions and share transfer instruments to complete the transaction. The company’s own rules and registers then need to be updated to reflect the new owner.
Plan Your Deal: Approvals, Valuation and Due Diligence
A smooth transaction starts with solid preparation. Before you negotiate terms, work through these foundations.
1) Check the Company’s Rules and Existing Agreements
Start by reviewing your constitution and any Shareholders Agreement. These documents often set out how shares can be sold, including pre-emptive rights (existing shareholders get first refusal), approval requirements, restrictions on transfers and timing or notice obligations.
Following these rules isn’t optional - missing a required approval or notice period can delay completion or spark a dispute. If anything is unclear, it’s wise to get a legal review early so you know the correct process.
2) Agree a Valuation Approach
Share price is a common sticking point. You can use a market-based method, a multiple of earnings or a formal expert valuation. If the business is complex or there are different share classes, consider formal valuation advice to help both sides land on a fair price. For context on methods and what affects value, see common approaches to valuing shares in a private company.
3) Scope and Prepare for Due Diligence
Due diligence is the buyer’s investigation into what they’re actually buying. Typical areas include financial performance, tax, material contracts, leases, IP, disputes, regulatory licences and employee arrangements.
To protect sensitive information during this process, parties usually put a Non-Disclosure Agreement in place before documents are shared through a data room.
4) Consider Tax and Duty
A share sale can trigger tax outcomes for sellers (for example, capital gains tax) and potential duty if a “landholder” threshold is crossed in certain states. Sprintlaw provides commercial legal help, but not tax advice - it’s important to speak with your accountant or tax adviser before you sign.
Step-By-Step: Legal Process for a Private Company Share Sale
Once you’ve aligned on the high-level terms, here’s the typical sequence for completing a sale of shares in an Australian private company.
1) Heads of Terms (Optional) and Exclusivity
Many deals start with a short heads of agreement or term sheet that records price, key conditions and exclusivity. While these documents are often non-binding (except for confidentiality or exclusivity), they set expectations and keep everyone aligned while the detailed contract is drafted.
2) Negotiate and Finalise the Share Sale Agreement
The Share Sale Agreement is the core contract. It sets out what’s being sold, the price and payment mechanics, pre-completion requirements, warranties and indemnities, and how completion will run. If directors are signing documents or instruments on behalf of the company, you’ll usually execute using the Corporations Act processes, such as signing under section 127.
Key clauses to focus on include:
- Conditions precedent (for example, required shareholder approvals or third-party consents).
- Warranties and disclosures (what the seller is promising and what’s been disclosed against those promises).
- Indemnities for specific risks (e.g. an ongoing dispute identified in diligence).
- Completion deliverables (resolutions, share transfers, updated registers, payments).
- Post-completion covenants (like non-compete or non-solicit restraints where appropriate).
This is one place where tailored drafting really matters. If you need support, our team regularly prepares and reviews a Share Sale Agreement for private company transactions.
3) Obtain Approvals and Third-Party Consents
Depending on your constitution or Shareholders Agreement, you might need board or shareholder approvals to proceed. Some major contracts (for example, a critical supply agreement or bank facility) may also require the counterparty’s consent if there is a “change of control” or assignment issue.
Note that personal guarantees typically cannot be assigned by deed; in practice, lenders and landlords usually require a new guarantee from the buyer group or a release for the exiting guarantor. If a contract needs to be transferred to a different company as part of a wider restructure, you’ll often use a Deed of Novation rather than an “assignment” for obligations.
4) Prepare Completion Documents
Leading up to completion, parties prepare and agree:
- Board and shareholder resolutions approving the transfer and updating officers if required.
- Share transfer forms, new share certificates and any required stamping or duty submissions where applicable.
- Updated cap table and share register entries.
- Payment mechanics (e.g. settlement statements and trust account arrangements).
If you’re transferring shares privately without going through an exchange, it’s generally called an off‑market share transfer - the documentation and registers need to reflect this correctly.
5) Completion (Settlement)
On completion, the buyer pays the purchase price and the seller delivers the executed transfer forms and other agreed documents. The company enters the buyer in the share register and issues the new share certificate.
This is a critical point: in Australian private companies, the transfer of legal title to shares takes effect when the company registers the transfer in its share register. ASIC notification is still required (see below), but it is not what makes the transfer legally effective.
6) Post-Completion Updates
After completion, the company must lodge the change with ASIC within 28 days. This is usually done via ASIC Form 484 (or subsequent ASIC forms that replace it), together with any officer changes. Late lodgements can attract penalties and cause confusion for future transactions.
Operationally, update bank mandates, trading accounts, insurance schedules and internal records. If there’s a continuing investor group, the shareholder register and any Shareholders Agreement should be updated to reflect the new ownership mix.
What Legal Documents Do You Need?
The exact paperwork depends on the size and complexity of the deal, but most private-company share sales will involve:
- Share Sale Agreement: The main contract recording price, conditions, warranties and the completion process. Many private deals use a tailored Share Sale Agreement rather than a generic template.
- Board and Shareholder Resolutions: Approving the transfer, issuing new certificates and any director or secretary changes.
- Share Transfer Forms and Certificates: Executed transfer instrument(s) and a new certificate issued to the buyer.
- Updated Share Register: The company’s register is the authoritative record of legal title for private-company shares.
- Disclosure Letter (and Bundle): Seller’s disclosures against warranties, plus supporting documents in a data room.
- Non‑Disclosure Agreement: Often used before diligence - a short-form NDA is common.
- Consents and Side Documents: Third‑party consents (landlords, banks, key suppliers), and where needed, a Deed of Novation to move a contract to a different entity as part of a broader restructure.
If your company has options, convertible notes or an employee share scheme, expect additional documents to deal with vesting, exercise or cancellation. Where personal guarantees are involved, buyers and sellers should plan for new guarantees or releases, noting the risks with personal guarantees continuing after completion.
What Laws Apply in Australia?
Several Australian laws and company rules come into play in a share sale. Here are the big ones to keep in mind.
Corporations Act 2001 (Cth)
The Corporations Act sets the framework for company governance, share capital and director duties. It also includes rules about execution of documents (for example, section 126 for agents and officers acting with authority and section 127 for company execution). Your constitution and shareholder approvals must align with these requirements.
Company Constitution and Shareholders Agreement
These documents are binding on the company and shareholders and often include pre‑emptive rights, transfer restrictions, drag/tag rights and approval thresholds. Always check them first - they can be more restrictive than the default legal position.
ASIC Lodgements
Private companies must keep ASIC’s records up to date. After the share transfer is registered in the company’s share register, lodge the shareholding changes with ASIC within the required timeframe, typically using Form 484 (or the current equivalent). Late fees can apply.
Australian Consumer Law (ACL)
Statements made during a sale process must not be misleading or deceptive. This includes claims about revenue, customer contracts and future performance. Warranties in the Share Sale Agreement should be accurate and supported by disclosures; otherwise, you risk an ACL claim. For the legal test and practical pointers, see the basics of misleading or deceptive conduct.
Employment Considerations
Because the employing entity stays the same in a share sale, employees usually continue on their existing terms with continuity of service. A share sale by itself does not ordinarily trigger redundancy. If you plan post‑completion changes (like restructures or role changes), get advice on Fair Work obligations, proper consultation and any entitlements that could arise.
Intellectual Property and Commercial Contracts
Confirm that key IP (trade marks, copyright, software) is owned by the company and that important contracts don’t contain change‑of‑control clauses that require consent. If something needs to move to a different entity as part of a broader restructure, a Deed of Novation is often the right tool for transferring ongoing obligations.
Tax and Duty
Share sales can give rise to capital gains tax for sellers. Certain state “landholder” regimes may impose duty if the company holds significant interests in land. Because these issues are fact‑specific, speak with a tax adviser before locking in the structure or signing the contract.
Common Pitfalls To Avoid
- Skipping the company’s rules: Proceeding without observing pre‑emptive rights or approval requirements can derail the deal.
- Thinking ASIC comes first: The transfer takes legal effect when the company updates the share register; ASIC must then be notified on time.
- Under‑scoping due diligence: Missing a key liability, licence gap or change‑of‑control clause can be costly for the buyer.
- Loose warranties and disclosures: Over‑promising without robust disclosures exposes sellers to claims and price chips.
- Guarantee blind spots: Personal guarantees don’t simply “assign” - plan for new guarantees or releases with lenders and landlords.
- Employee assumptions: A share sale doesn’t usually trigger redundancy, but planned post‑deal changes may - budget and consult accordingly.
- Missing completion mechanics: Unclear settlement statements, bank mandates or register updates lead to messy handovers.
Key Takeaways
- A share sale transfers ownership of the company itself; the company’s assets, contracts and employees stay with the same entity.
- Check your constitution and Shareholders Agreement early for pre‑emptive rights, restrictions and approval steps.
- Plan your valuation and diligence carefully, and protect information with a Non‑Disclosure Agreement before sharing documents.
- The Share Sale Agreement is the core contract - tailor it to your deal, including conditions, warranties, indemnities and completion deliverables.
- Legal title transfers when the company updates its share register; then lodge the change with ASIC (using Form 484 or its current equivalent) within the deadline.
- Personal guarantees generally cannot be assigned - expect to arrange new guarantees or releases, and use a Deed of Novation if obligations need to move to a different entity.
- Because tax and duty outcomes are specific to your circumstances, get advice from your accountant or tax adviser before you sign.
