As a business owner, understanding what a security interest is and how to utilise it correctly could be vital for the business in protecting certain assets. Whenever your business provides loans, enters into hire-purchase agreements, or leases goods, registering a security interest is crucial for protecting your capital. Failure to do so may expose your businesses to significant risks. For example, being unable to recover the full value of lost property if the grantor is insolvent or bankrupt. This article explains a security interest and why it should be registered.
What is the PPSR?
The Personal Property Securities Register (PPSR) is a crucial tool for individuals and businesses in Australia. It is the official government register for security interests in personal property. The PPSR, launched in 2012, helps resolve challenges in identifying whether an asset is secured and determining creditor priority when multiple security interests exist over the same asset.
What is a Security Interest?
A security interest is a legal right in property granted by one person (the grantor) to another (the secured party) to secure a debt or other obligation. In most cases, security interests are valid only if they are created by a consensual transaction or agreement that secures debt repayment or the performance of an obligation on the other party.
The Personal Property Securities Act (PPSA) defines a security interest in Section 12(1) as:
- a transaction that grants an interest in personal property; and
- secures payment or the performance of an obligation, regardless of the transaction’s form.
This definition covers traditional security transactions such as fixed and floating charges and assignments. Additionally, it extends to:
- retention of title clauses;
- hire purchase agreements;
- conditional sale agreements;
- leases (whether or not they are PPS leases); and
- flawed asset arrangements;
Registering Security Interests
These interests are registered on the PPSR, which acts as a public platform that provides people access to the following:
- Register Security Interests: Individuals and businesses can protect their claims by registering their security interests in personal property. This ensures that their interest is recognised and enforceable in case of default by the debtor.
- Search for Security Interests: The register allows users to search for existing security interests in specific personal property. This helps determine whether the property can be repossessed due to a prior security claim.
A common example of a security interest that would be registered on the PPSR is a Purchase Money Security Interest (PMSI). This typically arises when a business sells goods to a customer on credit terms, with the retention of title remaining with the seller until the goods are fully paid for. Registering a PMSI on the PPSR allows the seller to assert a super-priority claim over the goods if the buyer becomes insolvent or bankrupt before paying.
Another example is a company taking out a loan or finance to purchase equipment, vehicles or other assets. The lender will often require the borrower to grant them a security interest over those assets as collateral for the loan. Registering this interest on the PPSR protects the lender’s rights if the borrower defaults on repayments.

Many secured parties discover too late that their security interest are invalid and unenforceable, even if there are security agreements or retention of title clauses. The easiest way to avoid this issue is to register the security interest on the PPSR in accordance with the PPSA.
Using the PPSR to Protect Your Interests
Registering a security interest on the PPSR can protect your business when:
1. Buying or Acquiring Goods
Before finalising the purchase or acquisition of goods, it’s crucial to search the PPSR to determine if someone else has already registered a security interest over the items. This step is essential because:
- a search can reveal if the goods you intend to buy are already subject to a registered security interest;
- knowing about prior interests helps you assess the risk of repossession. If the goods have an existing security interest, the secured party may have the right to repossess them if the original owner defaults on their obligations; and
- purchasing goods with a registered interest without due diligence can lead to legal disputes and potential financial losses.
2. Selling, Hiring, or Leasing Goods
When you are on the other side of the transaction—selling, hiring, or leasing goods—it’s equally important to register your security interests on the PPSR. Doing so offers several benefits, such as:
- by registering your security interest, you publicly declare your claim over the goods. This protects you in cases where customers fail to pay or go bankrupt;
- a registered security interest gives you legal priority over other creditors. If your customer defaults, you stand first in line to recover the goods or their value; and
- having a registered interest mitigates the risk of financial loss, as it ensures you have a legal claim to recover your assets or their equivalent value.
Importance of a Well-Drafted Security Agreement
When conducting business transactions, it’s essential to have well-drafted security agreements in place. While these agreements offer legal protection, they may not safeguard your interests if the other party goes insolvent before payment.
In such cases, registering your security interests on the PPSR becomes crucial. Ultimately, this registration provides the secured party with an avenue for recovery, underscoring the importance of properly drafted security agreements to facilitate the necessary PPSR registrations.

Before buying a business, it is important to undertake due diligence, to verify the information supplied by the seller. This guide will walk you through the due diligence process.
Key Takeaway
Registering security interests on the Personal Property Securities Register (PPSR) is essential for protecting your business assets. This ensures that your claims are recognised and enforceable, reducing the risk of financial loss if a debtor defaults or goes insolvent. The PPSR provides a transparent platform to register and search for security interests, helping businesses safeguard their interests and make informed decisions. Properly utilising the PPSR and having well-drafted security agreements are crucial for maintaining priority and recovering the value of your assets in case of disputes or insolvency.
