- Property Law
Most people meet property law by accident. A landlord raises the rent with a fortnight’s notice. A fence turns out to sit half a metre inside a neighbour’s land. A contract for sale mentions an easement nobody explained.
None of these are exotic legal problems. They are ordinary situations, governed by a body of rules that quietly shapes where you live and what you can do there.
Here is what property law actually covers and why the basics deserve your attention, whether you are renting a unit or buying your first home.
What Is Property Law in Plain Terms?
Strip away the terminology, and this area of law answers three questions. Who holds rights over a piece of property? What do those rights allow? And how do they move from one person to another?
What it covers
Property law governs ownership, use, and transfer. It decides who holds rights over land and buildings, what those rights allow, and how they pass from one person to another.
That transfer can happen through a sale, a lease, a gift, an inheritance, or a mortgage. Each is a different mechanism with its own rules, which is why buying a house and inheriting one follow completely different paths.
What counts as property in law
So what is property in law? The definition is broader than most people expect. It stretches well past the house itself, taking in the land beneath, anything permanently fixed to it, and the various rights other people may hold over the same parcel.
Lawyers tend to describe ownership as a bundle of rights rather than a single thing you hold in your hand. Own a house, and you hold the right to live in it, rent it out, sell it, borrow against it, and leave it to someone in your will.
How those rights get divided
Here is the part that surprises people: the strands in that bundle can be separated and handed to different parties at the same time.
A landlord keeps ownership while a tenant holds the right to occupy. A bank registers an interest without ever setting foot inside. A neighbour may hold an easement letting them cross the driveway. All of these can sit over one property simultaneously, each perfectly valid.
Once you picture property as separate strands rather than one solid block, the rest of the subject gets much easier to follow.
How Australian Property Law Works
Ask what is Australian property law built on, and the answer begins in England. It descends from English common law, but the day-to-day rules now sit with the states and territories. New South Wales, Victoria, Queensland and the rest each run their own legislation on sales, leases, and land titles.
Every state and territory operates a Torrens title register. Ownership is recorded centrally rather than traced through a stack of historical deeds, and once an interest is registered, it is generally secure against competing claims. Lawyers call that principle indefeasibility. It is the reason buying property here is far safer than it was in the days of paper title chains.
Federal law plays a narrower role, mostly around foreign investment approval and tax. The things that affect renters and buyers directly, including leases, contracts, settlement, and disputes, are state matters.
Real property and personal property
Property splits into two broad categories, and the distinction shows up constantly.
- Real property covers land and anything permanently attached to it, such as houses, sheds, and fences.
- Personal property covers movable things, from furniture to vehicles to shares.
So what is real property law? It is the branch dealing with land and fixed structures. It is where conveyancing, leasing, mortgages, and boundary disputes all live, and it accounts for most of what a property law team handles day to day.
You will also come across two ways of holding land. Freehold means you own the property outright, subject to anything registered against it. ‘Leasehold’ means you hold the right to use it for a fixed term under a lease.
Where property law regulations come from
Clients often ask what is the law of property act that applies to them, and the honest answer is that there is no single national statute. Each state legislates separately, supported by property law regulations that fill in the technical detail. In New South Wales, the Conveyancing Act 1919 governs how property is sold and transferred, while the Residential Tenancies Act 2010 and the Retail Leases Act 1994 cover renting and commercial leasing, respectively.
These rules set out how contracts must be drafted, what a seller has to disclose, and how settlement is meant to run. Almost nobody reads them directly. A solicitor’s job is to turn them into advice you can act on.
Property Law Basics: The Terms That Catch People Out
A handful of concepts cause more confusion than the rest combined. Each one has cost someone money.
Fixtures in property law
What is a fixture in property law? It is an item attached to land or a building in a way that makes it part of the property itself. A built-in oven qualifies. So does a fitted kitchen or an in-ground pool.
Courts weigh two things: how firmly the item is attached and why it was put there. Australian courts generally treat the second question as the more important one. A heavy item can still count as a chattel if it was never meant to stay.
The distinction matters at settlement, because fixtures usually transfer with the property while loose items do not. A portable air conditioner stays with the seller unless the contract says otherwise. Arguments over dishwashers and light fittings are more common than you would think, and the fix is simple: list the grey items in the contract.
Charges and mortgages
Buyers frequently ask what is a charge in property law when one turns up on a title search. It is a claim registered against the title, almost always to secure a debt. A mortgage is the everyday example.
If a borrower defaults, the charge lets the lender recover what it is owed, sometimes by forcing a sale. Buyers should always confirm what is registered against a property before settlement. A title search reveals any charge that needs to be paid out or discharged first.
Contingent interests
What is contingent interest in property law? It is a right that only takes effect if something specific happens. A will might leave a house to a grandchild once they turn twenty-five. Until that birthday, the interest is real but not yet certain.
These show up regularly in wills and family arrangements. Left unidentified, they can stall a sale at the worst possible moment, which is one more reason to keep a will current. See, Do I Need a Will? if you are not sure where you stand.
The law on property boundaries
Neighbours argue over this constantly, so what is the law on property boundaries? It relies on the registered plan lodged with the state land titles office. Not the fence. Not the hedge. Not where the previous owner told you the line was.
Fences drift over decades. Driveways creep. Trees grow over the line and drop branches on someone else’s roof. A licensed surveyor can re-establish the true boundary, and separate dividing fence legislation then determines who pays for what.
Why Property Law Matters When You Rent
Renters deal with this area of law constantly, usually without noticing. The protections are real, and they exist because the law recognises tenants and landlords do not start from equal footing.
- Your lease has to comply with your state’s residential tenancy legislation, whatever the agreement says.
- Your bond is held by a government authority rather than the landlord. In New South Wales that is, NSW Fair Trading, through Rental Bonds Online.
- Rent increases are limited in frequency, generally to once every twelve months, and require written notice.
- A growing number of states now require a valid reason to end a tenancy. New South Wales abolished no-grounds evictions in May 2025.
- The property must be liveable, which covers working locks, functioning plumbing, and timely repairs.
- A landlord cannot simply turn up. Entry requires notice, with narrow exceptions for emergencies.
Knowing these exist changes how you respond when something goes wrong. Plenty of tenants accept conditions they were never obliged to accept.
Three situations catch renters out repeatedly. The first is repairs, where urgent problems such as a burst pipe or a gas leak carry far shorter response times than general maintenance. The second is termination, because a notice that fails to meet the statutory requirements may not be valid at all. The third is the bond. Photographs taken at the start and end of a tenancy settle more of those arguments than any amount of correspondence.
Why Property Law Matters When You Buy
A purchase is likely the largest transaction of your life, and legal rules shape almost every stage of it. If this is your first purchase, our guide for first-time property buyers walks through each of these steps in more depth.
- The contract for sale must disclose specific information before the property can be marketed.
- A cooling-off period applies in most states, though not all, and never at auction. New South Wales allows five business days on residential purchases, extended to ten for off-the-plan contracts.
- Title searches confirm the seller genuinely owns the property and reveal anything registered against it.
- Settlement is a formal legal process with strict timing, not just an exchange of keys.
- Transfer duty, usually called stamp duty, applies in every state and territory, though first home buyer concessions vary widely between them.
Most expensive mistakes happen when someone skips advice at one of these points.
Buying with someone else
Purchasing with a partner, a sibling, or a friend raises a question people often answer without thinking: how will you hold the title?
Joint tenancy means equal shares, with one significant consequence. If a co-owner dies, their share passes automatically to the survivors regardless of what their will says. Tenants in common work differently. Each owner holds a defined share, equal or unequal, and that share passes under their will.
The choice carries genuine estate planning and tax consequences. It is one of the property law basics worth settling before you buy rather than after, because changing it later means fresh paperwork and sometimes duty. We’ve set out the trade-offs between the two structures in more detail in Joint Tenants vs Tenants in Common Explained.
Where Commercial Property Law Differs
So what is commercial property law? It applies to premises used for business: offices, shops, warehouses, and industrial sites. It overlaps with the residential side, but the protections are far thinner.
Commercial leases are lightly regulated by comparison. Retail lease legislation gives small business tenants some safeguards, though many consumer protections built into residential tenancies simply do not apply. Terms are negotiated rather than assumed, which is why a specialist leasing team reviews them clause by clause rather than relying on a standard form.
Development approvals, planning conditions, strata schemes, and joint venture structures also feature heavily on the commercial side. A lease over a warehouse and a lease over a flat are legally quite different animals.
Real Estate and Property Law: Who Does What
Real estate and property law are related but distinct. An agent markets the property, finds a buyer, and negotiates the price. A lawyer handles the legal machinery underneath, making sure the deal survives contact with reality.
What property lawyers actually do
- So what do property lawyers do day to day?
- Review and negotiate contracts before anyone signs
- Run title and property searches
- Advise on stamp duty and any available concessions
- Prepare and lodge the documents that transfer ownership
- Attend settlement on your behalf
- Act in disputes over contracts, boundaries, or ownership
Conveyancers handle straightforward transfers competently and often cost less, and CLS Legal’s own conveyancing team covers exactly that ground. A lawyer becomes worth the difference once a matter turns complicated, because they can also run the dispute if one develops.
Before You Sign Anything
Nobody expects a renter or a first-time buyer to master this material. What matters is recognising the moments that carry risk and knowing when a second opinion is worth paying for.
Read the lease. Get the contract reviewed before exchange, not after. Ask what is registered against the title. Those three habits prevent most of the problems people bring to a solicitor too late.
