A lien is a legal right or interest a creditor holds in someone else's property—real or personal—to secure payment of a debt or performance of an obligation. Put simply, a lien gives the creditor an enforceable claim over property until the underlying debt is satisfied. Liens can operate as an encumbrance on land, a possessory right over goods, or an equitable interest recognised by court order or statute.
Understanding what a lien is and how liens work is essential for anyone buying property, taking security over assets, hiring trades, or lending money. This guide covers how liens arise, the main types, how to record and enforce liens (PPSR, land titles, ASIC), and practical steps to challenge or remove a lien.
A lien can be created in several ways:
Examples:
Liens appear in different forms. Below are the core categories with practical examples.
A statutory lien is created by legislation. Common examples include building-and-construction security regimes that give contractors or subcontractors a lien-like claim over the land or contract funds until payment. These schemes often set fast timelines and notice requirements for making and enforcing claims. See construction liens for related rules and procedures.
A possessory lien arises when a service provider or bailee retains possession of goods supplied or repaired until payment is made. Typical examples are repairers, mechanics and storage operators. The lien generally ends if the lienholder voluntarily surrenders possession, or where statutory or contract rules restrict retention.
An equitable lien is imposed by a court where justice requires it — for example, when a person advances funds to improve property and a proprietary right should secure repayment. Equitable liens are not normally registrable on land titles by themselves but can be enforced through court orders.
A contractual lien is created by agreement between parties. A common form is a retention-of-title clause: a supplier retains ownership of goods until the buyer pays. Contractual liens can interact with the personal property register: where goods become part of business assets, the supplier should consider registering a security interest on the PPSR.
A maritime lien is a specialised in rem claim against a vessel for services, salvage, crew wages or damage. Maritime liens rank highly and can survive changes in vessel ownership until discharged by court or settlement.
Understanding where and how to record a lien is central to protecting priority and enforcing rights.
Interests affecting land are usually registered at the applicable land titles office as easements, mortgages or caveats. A caveat is a notice of interest that serves to warn third parties of a claimed interest in land and can prevent registrable dealings while it remains effective. A caveat does not itself determine priority — courts and the registry rules assess competing claims. For practical caveat guidance, see caveat.
The Personal Property Securities Register (PPSR) records security interests in personal property and goods. Registering (perfecting) a security interest on the PPSR is often essential to preserve priority against other creditors and receivers. Perfection methods include registration, possession (for some types of collateral) or control (for certain financial collateral). A timely PPSR registration generally beats later unregistered claims.
External guidance: the AFSA provides PPSR search tools and registration information at https://www.ppsr.gov.au/ and https://www.afsa.gov.au/
When companies create charges over their assets, sections of the Corporations Act require lodgement of charges with the companies register. Filing with ASIC secures public notice of the charge and affects priority against unsecured creditors or new financiers. See ASIC guidance at https://asic.gov.au/ and further detail in our company charge guide.
Priority typically follows:
Example: A supplier who ships specialised equipment to a buyer but fails to register a PPSR security interest risks losing priority if the buyer grants a subsequent registered charge to a financier.
For interactions between retention-of-title clauses and security registration, see security interest and consider registering on the PPSR. For insolvency interactions and priorities, see insolvency and our charge registration guidance.
Lienholders have several enforcement options; the availability depends on the lien type, registration status and statutory limits.
Key constraints:
See our debt recovery and judgment debt guides for practical steps when enforcing a judgment or lien.
If you're a debtor, or a third party affected by a lien, remedies and steps include:
To clear a PPSR registration, ask the secured party to lodge a discharge statement; if they refuse, there are dispute procedures including lodging a verification statement and seeking court orders. For company charges, ASIC's registry holds the lodgement and discharge records; search at https://asic.gov.au/.

If you are a creditor:
A registered caveat or charge often prevents registrable dealings until resolved. A possessory lien can hinder transfer of goods while the lienholder holds them. The practical effect depends on the lien's nature and whether it is registrable.
Duration varies. Some statutory liens expire if not enforced within set times; registered security interests last until discharged; possessory liens end when possession is surrendered or goods are lawfully sold under procedure. Check the specific legislative scheme.
A mortgage is a legal interest in land granted as security and is registered on the land title. A lien is a broader category of claim that can be possessory, equitable or statutory and may not require registration on land titles. See mortgage charge for comparison.
Perform a PPSR search (PPSR), land title search for caveats, and an ASIC company search for company charges. Use official registry websites for up-to-date records and consider a professional search via a conveyancer for land title matters.
Costs include legal fees, registry fees for discharges, potential security to obtain release, and court costs if litigation is required. The exact amounts depend on the process and complexity.
Yes: you can seek removal or stay by agreement, provide security, or apply to court to have the lien removed, particularly if the claimant failed to comply with statutory notice or registration requirements.
Payment may settle the debt and remove the lien; whether you can recover funds paid under protest depends on circumstances, contractual rights, and potential counterclaims.
A lien is a legal claim that creditors can place on property or goods to secure payment of a debt. Liens can be statutory, possessory, equitable, contractual, or maritime, and their enforcement and removal depend on how they are registered—via the PPSR for personal property, land title registers for real property, or ASIC for company charges. If you discover a lien affecting your assets, search the relevant registers, gather supporting documents, contact the claimant to negotiate discharge, and seek professional legal advice to protect your interests and comply with statutory notice requirements.
