Can siblings force the sale of an inherited property in Australia?

Yes. A co-owner can apply to the court to force a sale - in New South Wales under section 66G of the Conveyancing Act 1919, which allows trustees to be appointed to sell, and through equivalent processes in the other states. Courts grant these applications readily, but the costs of getting there are significant.

Do you pay stamp duty when buying out a sibling on an inherited house?

Usually yes on the portion you acquire beyond your entitlement under the will. Transfers made strictly in conformity with the will can attract concessional duty, but a cash buyout of another beneficiary is generally dutiable at market value. Check your state revenue office, as the rules differ.

Does a sibling living in an inherited house have to pay rent?

Not automatically. Each co-owner generally has a right to occupy the whole property, so an occupying sibling is not required to pay rent by default. Occupation rent can be brought into account in a dispute or when the property is sold, but the reliable fix is agreeing the arrangement in writing in advance.

What is the two-year rule for inherited property?

Where the property was the deceased person's main residence, a sale settled within two years of the date of death is generally exempt from capital gains tax. Beyond that window the exemption can be lost or apportioned, though the Commissioner has discretion to extend the period in some circumstances.

How do you value an inherited house fairly between siblings?

Appoint one valuer jointly, before anyone has a number in mind, and agree in advance that the result binds everyone. Agreeing on the valuer is far easier than agreeing on the valuation after the fact.

Inheriting a House With Siblings in Australia: Your Options

You and your siblings now co-own a house nobody chose to buy together. Here are the five ways it usually goes, what each one costs in duty and CGT, and how to stop the one where somebody just lives there.

This article is general information only and is not legal, financial, tax, or property advice. Consider advice from a qualified professional for your circumstances.

Co-owners by accident

Most people who co-own property in Australia decided to. They found a place, agreed a split, signed something. Inheriting the family home with your siblings works the other way around: the arrangement lands on you fully formed, usually in equal shares, usually while everyone is grieving and nobody wants to be the one who mentions money.

The result is a co-ownership with no agreement, no agreed exit, and no rules about who pays the rates. It's the single most common way Australians end up owning property together badly.

The good news is that the decisions are finite. There are really only five things you can do, and the families that come out of this intact are the ones who pick one deliberately and early.

First: you don't own it yet

Before any of the options are live, the estate has to be administered. The executor applies for probate, and the property is transferred out of the deceased's name — either into the beneficiaries' names by a transmission application, or into the executor's name so it can be sold from the estate.

That gap matters more than people expect. Until the transfer happens, you're a beneficiary with an entitlement, not a registered owner, and you can't sell, mortgage or transfer anything. It also creates a useful pause: decisions made before the transfer can sometimes be structured more cleanly than the same decision made two years later, particularly around duty. Ask the estate solicitor about this early rather than after everyone has dug in.

Option one: sell it and split the proceeds

The cleanest ending, and the one most estates take. The property is sold, costs come out, and the net proceeds are divided according to the will.

Selling from the estate, before the property is transferred into individual names, is usually the simplest path administratively. There's also a capital gains consideration that rewards not dithering: where the property was the deceased's main residence, a sale settled within two years of the date of death is generally exempt from CGT. Miss that window and the exemption can be lost or apportioned, which turns a delay into a tax bill. Commissioner discretion to extend the period exists in some circumstances, but planning to need it's not a plan.

Option two: one sibling buys the others out

Very common where one person has a genuine attachment to the house, or already lives there.

The mechanics are straightforward and the arguments are always about the same two things. Start with a valuation everyone agreed to in advance — one valuer, appointed jointly, before anyone has a number in their head. Agreeing the valuer is much easier than agreeing the valuation. Then the buying sibling needs finance, and this is a normal enough transaction that most lenders and brokers have done it before.

The buyout calculator will run the equity maths, and how to buy out a co-owner covers the process in detail.

Duty is the part that catches people. A transfer made strictly in conformity with the will can attract concessional duty in most states. A buyout is usually a different animal: one beneficiary is paying cash to acquire more than their entitlement under the will, and the portion they acquire beyond that entitlement is generally dutiable at market value. Revenue NSW publishes worked examples of exactly this scenario, and the other state offices have their own rules. Get the numbers from your state revenue office or the estate solicitor before you shake hands, because duty on half a house isn't a rounding error.

Option three: keep it and rent it out

Sometimes the property is worth holding, or the market is wrong, or nobody can face selling the family home yet.

This works, but understand what you've just done: you've become property investors together, without any of the paperwork investors normally sign. Rental income and expenses must be split by legal ownership interest for tax purposes — a private agreement to share them differently has no effect on the ATO's view. Land tax may now apply where it didn't before, since none of you live there. Someone has to deal with the agent, the repairs and the tax returns, and "someone" quietly becomes one sibling doing all of it and resenting the others.

If you go this way, write an actual co-ownership agreement. Who approves a repair over $2,000, who holds the reserve, how a sibling exits, what happens when one of you needs the money. Our guide to co-ownership agreements covers what belongs in one.

Option four: one sibling lives there

This is where the real fights start, and it's the option families drift into rather than choose.

The default legal position surprises people. Each co-owner generally has a right to occupy the whole property, and a co-owner in occupation isn't automatically required to pay rent to the others. Your sister living in the house isn't, by default, doing anything wrong — and the others aren't, by default, entitled to anything for it.

Occupation rent can be brought into account, but usually only in specific circumstances: where the occupying owner has excluded the others, or as an equitable adjustment when the property is finally sold or divided, often alongside a claim by the occupier for the rates, insurance and repairs they have been covering. It's a remedy that surfaces during a dispute, not an automatic monthly invoice.

Which is exactly why you shouldn't rely on it. If one sibling is going to live there, agree in advance what they pay and what they cover — and get it in writing while everyone is still reasonable. When one co-owner lives in the property works through the fair models and the numbers.

Option five: do nothing

Not really an option, but it's the most popular one. Nobody wants to push, so the house sits, the rates get paid by whoever is most conscientious, and four years later the CGT exemption has gone and one sibling has moved in and everyone communicates through a solicitor.

When you can't agree

If one sibling refuses to sell and refuses to be bought out, the others aren't stuck forever. Australian law lets a co-owner apply to the court to force a sale.

In New South Wales, section 66G of the Conveyancing Act 1919 lets a co-owner apply to have trustees appointed to sell the property, and the courts grant it close to as a matter of course — a co-owner who wants out is generally entitled to get out. Victoria, Queensland and the other states have their own equivalents, with applications going to VCAT in Victoria and to the courts elsewhere. The details differ; the principle doesn't.

Understand the cost of getting there. Trustees charge, lawyers charge, and a court-ordered sale rarely achieves what a well-presented private sale would. It's the backstop that makes negotiation work, not a good outcome in itself. Knowing it exists is usually more valuable than using it — a sibling who understands that a sale can be forced tends to negotiate rather than stonewall.

The tax bits worth knowing

Three things do most of the damage:

The two-year rule. Where the property was the deceased's main residence, selling within two years of the date of death is generally CGT-exempt. This is the single most valuable deadline in the whole process.
Your cost base isn't what they paid. For a property the deceased acquired after September 1985 and used as their main residence, beneficiaries generally take a cost base equal to the market value at the date of death. Get a retrospective valuation as at that date and keep it, even if you aren't selling yet. Reconstructing it later is expensive and unconvincing.
Land tax. An inherited property nobody lives in isn't anybody's main residence, so land tax may apply, with thresholds and rules differing by state.

None of that's advice for your situation. Inherited property is one of the areas where an hour with an accountant pays for itself, and the hour is much cheaper before you act than after.

If you're keeping it, make it a real arrangement

The families that manage inherited property well treat it as what it now is: a co-owned asset with several owners who didn't choose each other. That means a written agreement, an agreed way to value a share, a first right of refusal, and one honest record of who has paid what.

That last part is where most of the resentment comes from. One sibling covers the insurance, another fixes the hot water, a third pays nothing for two years, and nobody is keeping score until suddenly everybody is. Laddered exists for exactly this — one shared ledger, every cost split by the shares you agreed, visible to all the owners — so that when someone does want out, the settling up is a report rather than an argument about 2024.

This is general information rather than legal or tax advice, and estate law and duty rules differ meaningfully between states. Talk to the estate solicitor and an accountant early. The families who fight about an inherited house rarely fight about the house itself. They fight because nobody wrote anything down while they still liked each other.
