If you run a business, you’re constantly dealing with “rights” - the right to be paid, the right to use a name, the right to stop someone copying your work, or the right to take back goods if a customer doesn’t pay.
Some of these rights are proprietary rights, which (in simple terms) are rights you have in relation to property. Understanding what a proprietary right is can help you protect your assets, negotiate better contracts, and reduce risk when you buy, sell, lend, or invest.
In this guide, we’ll break down what a proprietary right means in an Australian business context, how it’s different from a personal (contractual) right, and what practical steps you can take to protect what your business owns and controls.
What Is A Proprietary Right?
A proprietary right is a legal right that relates to property - meaning something you can own, control, transfer, or use to secure an obligation.
In most cases, a proprietary right:
- can be enforceable against people generally (not just one specific person);
- can often be transferred or dealt with (for example, sold or assigned, or you might grant a licence or give it as security, depending on the type of right); and
- may continue to affect the property even if the property changes hands (for example, where the right is registered or otherwise legally recognised as binding on third parties).
When people ask what a proprietary right is, they’re usually trying to work out whether they truly have something like “ownership” (or an ownership-like interest), or whether they simply have a promise from someone else.
From a small business perspective, proprietary rights can show up in areas like:
- ownership of business assets (equipment, stock, vehicles);
- intellectual property (like brand names, logos, designs and software);
- shares and other interests in a company;
- security interests over assets (for example, when finance is involved); and
- rights connected to land (though land has its own “real property” rules and registers).
Because proprietary rights can be powerful, it’s important to get clear on what you actually have before you rely on it - especially when money, growth, or disputes are on the line.
Proprietary Rights vs Personal Rights: Why The Difference Matters
A practical way to understand a proprietary right is to compare it to a personal right (also called a contractual right).
Personal Rights (Contractual Rights)
A personal right is usually a right you have against a particular person, because they promised something in a contract.
For example:
- If a customer agrees to pay your invoice, your right to be paid is a personal right against that customer.
- If a supplier agrees to deliver goods next week, your right to delivery is a personal right against that supplier.
If the other party doesn’t do what they promised, your remedy is usually to enforce the contract (for example, recovering damages). Whether a contract is enforceable will depend on the usual contract principles, including offer, acceptance and intention - which is why it helps to understand what makes a contract legally binding.
Proprietary Rights (Rights In Property)
A proprietary right is closer to having a legal interest in the asset itself (or an asset-like right). That often means you can have stronger protection if things go wrong, particularly where third parties are involved (for example, if someone becomes insolvent or tries to deal with the property in a way that harms you).
For example:
- If your business owns equipment, you may have proprietary rights in that equipment (ownership).
- If you hold a registered trade mark, you can often stop others using a confusingly similar brand (rights in that IP).
- If you take a security interest over a customer’s equipment to secure payment, you may have a proprietary-style right that can give you priority over other creditors (if done correctly).
Why it matters for your business: if you assume you have a proprietary right when you only have a personal right, you may find you have far less protection than you expected - particularly in a dispute, a business sale, or an insolvency scenario.
Common Proprietary Rights In Australian Business (With Examples)
Proprietary rights aren’t a single “one size fits all” concept. They show up in different ways depending on what your business does and what assets you rely on.
1. Ownership Of Physical Assets
This is the most familiar type of proprietary right - ownership of “things” your business uses to operate, such as:
- stock and inventory;
- tools and equipment;
- vehicles;
- computers and devices; and
- furniture and fit-out items.
In day-to-day operations, ownership sounds straightforward. But ownership can get complicated if:
- assets are financed or leased;
- you buy goods on terms where title passes later (retention of title clauses);
- assets are purchased in one entity but used by another (common in group structures); or
- you’re buying a business and need to confirm what is actually included in the sale.
2. Intellectual Property (IP) Rights
For many small businesses, your most valuable assets aren’t physical - they’re brand and know-how. Proprietary rights can exist in intellectual property, such as:
- trade marks (brand names, logos, slogans);
- copyright (written content, software code, marketing materials);
- designs (product appearance); and
- confidential information (trade secrets, formulas, customer lists).
If your brand is part of how customers find and trust you, protecting it early is usually worth it. A common step is to register your trade mark so you’re not relying solely on informal “I used it first” arguments.
Also, when you share business plans, product concepts, or financials with third parties, protecting confidentiality is key. In many situations, a Non-Disclosure Agreement can help clarify what information is confidential and what the other party can (and can’t) do with it.
3. Shares And Ownership Interests In A Company
If your business is a company, shares are another example of a proprietary right. A share generally represents a bundle of rights (which can include voting rights, dividend rights and rights on winding up).
This becomes especially relevant when:
- you bring on a co-founder or investor;
- you want clear rules around decision-making;
- someone exits the business; or
- you’re planning for future fundraising.
A Shareholders Agreement is often used to record the commercial deal between shareholders and reduce the risk of disputes that can threaten control of the business.
4. Security Interests Over Personal Property (Finance And “Who Gets Paid First”)
Security interests are a common area where proprietary rights become very practical for businesses.
For example, if you supply goods on credit, you might try to retain rights over those goods until you’re paid (often through contractual terms). If your business lends money, you might want rights over an asset until the loan is repaid.
In Australia, security interests over many types of personal property are often recorded on the Personal Property Securities Register (PPSR). While the law here can get technical, the business takeaway is simple: if you want priority over an asset, you generally need to make sure the security interest is properly documented and (where required) registered.
If your business uses security arrangements, it’s also worth understanding what a general security agreement is, because this document is commonly used to secure obligations over a broad range of assets.
5. Equitable Interests (Where The “Paperwork” Doesn’t Tell The Full Story)
Sometimes, rights that look “property-like” can arise even when someone isn’t the “registered owner” on paper.
These situations can involve what the law calls “equitable interests” - for example, where:
- property is held by one party on trust for another; or
- someone has contributed to an asset and claims an interest even if their name isn’t on the title.
These issues can be particularly relevant in business purchases, disputes between founders, or informal arrangements where ownership was never properly documented.
How Do You Create, Transfer Or Protect Proprietary Rights?
One of the most useful ways to think about proprietary rights is as a lifecycle:
- creation (how the right comes into existence),
- evidence (how you prove you have it),
- transfer (how you sell, assign, or license it), and
- enforcement (how you stop others interfering with it).
Creation: How Proprietary Rights Arise
Proprietary rights can arise through different mechanisms, including:
- Purchase (you buy an asset and ownership transfers to you);
- Registration (for example, registering a trade mark);
- Creation of work (for example, copyright in original materials);
- Agreement (for example, security interests, assignments, licences); and
- Equity (for example, trusts and other equitable arrangements).
What matters for your business is that different types of proprietary rights have different “rules”. You can’t treat a customer list the same way as a forklift, and you can’t treat a logo the same way as cash in the bank.
Evidence: Proving Your Rights
If a dispute happens, you’ll want clear evidence of what you own (or what rights you have). Useful evidence often includes:
- purchase invoices and receipts;
- asset registers;
- IP registrations (where applicable);
- signed contracts showing transfer, assignment or licensing; and
- records of who created work, and when (especially for copyright-heavy businesses).
It’s a good habit to keep these documents organised from day one. It’s much harder to “rebuild” ownership records when you’re already in a dispute or trying to sell the business.
Transfer: Selling, Assigning Or Licensing Proprietary Rights
Businesses deal with proprietary rights all the time - even if they don’t call it that.
Common examples include:
- selling equipment to another business (transfer of ownership);
- licensing software to customers (permission to use IP without transferring ownership);
- assigning IP created by a contractor to your business (so the business owns it); and
- selling shares to a new shareholder (transfer of a proprietary interest in a company).
The key point is that these arrangements should be documented clearly, because unclear transfers (or unclear licences and permissions) can create disputes about who owns what - and that can reduce business value or derail a deal.
Protection: Reducing The Risk Of Losing Control
Protecting proprietary rights usually involves a mix of:
- contracts (clear terms about ownership, permitted use, and consequences of breach);
- registrations (where relevant, like trade marks);
- internal processes (asset registers, access controls, staff training); and
- enforcement (acting early when someone infringes your rights).
Many business owners only focus on protection when a problem appears - but you’ll usually be in a stronger position if you set things up properly before you scale, hire, raise capital, or expand into new markets.
What Legal Documents Help Protect Proprietary Rights?
Because proprietary rights often sit at the heart of business value, it’s worth making sure your documents match your commercial reality.
Not every business needs every document below, but these are some of the most common legal tools that help protect proprietary rights in a practical way.
- Customer Terms and Conditions / Service Agreement: helps set out payment terms, ownership of deliverables (especially for creative or software work), and what happens if a customer doesn’t pay.
- Supply Agreement: can clarify when title and risk pass, and whether any retention of title arrangements apply.
- Non-Disclosure Agreement (NDA): helps protect confidential information when you’re sharing sensitive material with potential partners, contractors, or buyers.
- IP Assignment or IP Licence: critical if you hire contractors or collaborate, so your business clearly owns what it needs to own (or has the right to use it).
- Shareholders Agreement: helps manage ownership and control rights in the company, including what happens if someone wants to exit or transfer shares.
- Company Constitution: can set baseline rules for governance and share issues/transfers (particularly important as you grow and bring on investors).
- Privacy Policy: if you collect personal information (for example, via your website, subscriptions, or marketing), a clear Privacy Policy helps explain how you handle that data and reduces compliance risk.
One practical tip: when you’re drafting contracts, pay close attention to ownership clauses, assignment clauses, and restraints around use of information. These clauses are often where proprietary rights are created, limited, or accidentally given away.
If you’re ever unsure whether a document actually protects your position (or creates the proprietary right you think it creates), it’s worth getting legal support early - it’s usually cheaper than fixing the issue after a dispute or failed deal.
Key Takeaways
- A proprietary right is a right relating to property, and it can often be enforceable beyond just one contracting party.
- For business owners, the difference between proprietary rights and personal (contractual) rights matters most when there’s a dispute, insolvency, business sale, or power imbalance.
- Common proprietary rights in business include ownership of physical assets, intellectual property rights, shares, security interests, and (in some cases) equitable interests.
- Protecting proprietary rights usually comes down to getting the structure and documentation right - including registrations (where needed) and clear contracts that deal with ownership and permitted use.
- Strong legal documents (like NDAs, IP assignments/licences, and shareholders arrangements) can prevent costly misunderstandings and help preserve business value.
