Granny Flat Agreements in Victoria: Legal, Tax and Elder Law Considerations
Granny flat arrangements can be a sensible alternative to residential aged care — but they involve significant sums, real elder-law risk and specific Centrelink and tax rules. This guide sets out the legal structure and the safeguards that should be in place before assets change hands.

Key points
- A granny flat arrangement commonly involves an older person transferring money, property or other assets in exchange for a right to live in a specified home. To qualify as a granny flat interest for Centrelink purposes and for the federal CGT exemption, the right generally must be for life.
- It is not simply a family understanding — for Centrelink and CGT purposes, a granny flat interest is a defined concept with specific evidentiary requirements.
- From 1 July 2021, a formal granny flat interest that meets the Commissioner's requirements is CGT-exempt on creation, variation and termination; without a formal arrangement, CGT can apply to transfers of property.
- For Centrelink means-testing, a properly documented granny flat interest generally is not treated as a deprived asset, but the "reasonableness test" limits how much can be paid before deprivation rules apply.
- Written granny flat agreements should record the parties, consideration, the older person's rights of residence, contributions to outgoings, exit arrangements, dispute-resolution and what happens on the family member's death, divorce or bankruptcy.
- Granny flat arrangements are a known elder-law risk area — independent legal advice for the older person, and consideration of Wills, powers of attorney and family provision exposure, should occur before money changes hands.
A granny flat arrangement is not a casual family understanding. It is a legal arrangement where an older person typically transfers a large portion of their wealth to a family member in return for a right to live in a home. When the paperwork is done properly, it can suit both sides. When it is not, the older person can lose their home, their capital, or both. This article sets out how granny flat agreements work in Victoria and the legal, tax and elder-law issues that should be considered before any money moves.
General information only, not legal, financial or tax advice. Independent legal advice for the older person is essential.
What a granny flat agreement is
A granny flat arrangement (sometimes called a granny flat agreement) is an arrangement under which the older person transfers money, property or other assets to a family member. In return, the older person receives a right to live in a specified home, together with related rights such as access to shared areas, contributions to outgoings and support arrangements.
A private family agreement can provide a fixed-term occupation right. However, a qualifying granny flat interest for Services Australia purposes and for the federal CGT exemption generally requires a lifetime right of occupation. A fixed-term right may still be enforceable as a matter of contract or equity, but it does not automatically qualify for the statutory Centrelink or CGT treatment.
The home may be owned by the family member, or it may be built or renovated with money contributed by the older person. The right of occupation does not have to be registered on title; typically it is not.
Centrelink treatment
Services Australia separately considers whether the amount transferred is reasonable and how the granny flat interest is treated under the assets test. In relevant cases, the reasonableness test determines whether any part of the transfer is treated as a gift or deprived asset.
The entry contribution also affects whether the person is treated as a homeowner. If it exceeds the applicable extra allowable amount, the person will generally be treated as a homeowner and the value of the granny flat interest will not be counted as an assessable asset. If it is equal to or below that amount, the person will generally be treated as a non-homeowner and the entry contribution may remain assessable. The outcome should be checked with Services Australia before assets are transferred.
Tax and CGT
From 1 July 2021, eligible CGT events arising from the creation, variation or termination of a qualifying granny flat arrangement are disregarded, provided the statutory eligibility requirements are met. In outline:
- the arrangement must be in a written agreement;
- it must give the individual the right to occupy the property for life;
- it must be entered into because of family or other personal ties; and
- the individual must have reached age pension age or have a disability.
The concession does not exempt unrelated CGT events, including a later sale of the property by the owner. Tax advice should be tailored to the parties' circumstances.
The written granny flat agreement
A written agreement is required for the federal CGT exemption and is strongly advisable for Centrelink purposes and for preventing disputes. Although Services Australia may accept an unwritten arrangement, proving its existence and terms can be considerably more difficult. Well-drafted granny flat agreements record:
- the parties, and the property involved;
- the consideration provided by the older person (money, property or both);
- the right of residence — the exact area, exclusive-occupation rights, shared access, and duration;
- contributions to outgoings — rates, utilities, insurance, maintenance;
- what happens if the older person needs to enter residential aged care;
- what happens if the family member wants to sell;
- what happens if the family member dies, separates or becomes bankrupt;
- dispute-resolution steps; and
- refund or exit arrangements.
Ownership structures and title
Granny flat arrangements are structured in several different ways, each with different consequences:
- Cash contribution. The older person contributes to the purchase price, extension or building of the property. Title remains with the family member. The older person has a contractual right of occupation.
- Transfer of the family home. The older person transfers their home to the family member. This is the highest-risk structure for the older person and requires the most careful advice.
- Proprietary or title-based protection. Some arrangements give the older person a life estate, lease or other proprietary interest capable of protection through the land-title system. Other arrangements create only contractual rights. The available protection, and any duty and tax consequences, depend on the structure selected.
- Joint ownership. The older person and the family member hold the property as tenants in common. Family law risk on the family member's separation is a particular concern here.
The choice of structure has significant Centrelink, CGT, stamp duty and estate consequences. It is not a "documentation" question — it is a design question that should be worked through before any contract is signed.
Elder-law risks and safeguards
Granny flat arrangements are a known area for suspected elder financial abuse. The older person often transfers most of their liquid wealth to a family member they trust and then depends on that family member for housing. If the relationship deteriorates, or if the family member's circumstances change, the older person can be badly exposed.
The essential safeguards are:
- independent legal advice for the older person, separately from the family member receiving the benefit, is strongly recommended;
- capacity considered and documented at the time the arrangement is entered;
- the arrangement documented in a written agreement that addresses exit;
- Wills and powers of attorney reviewed at the same time;
- consideration of family provision (TFM) exposure to other children; and
- a contingency plan for residential aged care, if the older person's needs change.
Where an existing arrangement is showing warning signs of misuse, see our guide to elder financial abuse in Victoria.
What happens if the older person needs residential care
Older people who enter granny flat arrangements sometimes later need residential aged care. The written agreement should address:
- whether the older person is entitled to a refund of some or all of the consideration paid;
- how any refund is calculated;
- timing of payment; and
- how the funds will be used (for example, to pay a Refundable Accommodation Deposit).
Where the older person still has capacity, they can decide whether to invoke the exit provisions. Where capacity has been lost, decisions typically fall to an attorney or an administrator — which is why a valid enduring power of attorney is so important.
Wills, TFM claims and equalisation
Granny flat arrangements often involve one child receiving a significant benefit compared with other children. This can complicate estate planning. Where the older person's Will divides the residue equally between children, the child who received the granny flat benefit will have received a substantial extra benefit. Where the Will is adjusted to compensate other children, family provision (TFM) claims can still be a concern. The estate plan and the granny flat arrangement should be considered together, not separately.

Frequently Asked Questions
What is a granny flat agreement?
The term is used in two different ways. First, an ordinary granny flat or family occupation agreement is a private family arrangement under which an older person is given a right — for life or for a fixed term — to live in a specified home, usually in return for money, property or other assets. Second, a statutory granny flat interest is a narrower concept used for Centrelink means-testing and for the federal CGT concession, and generally requires a lifetime right of occupation together with other eligibility requirements. The two arrangements can overlap, but they are not the same and should not be treated as interchangeable.
Is a granny flat interest treated differently for Centrelink?
Services Australia applies two separate tests. Under the reasonableness test, the amount transferred is compared with a reasonable value calculated from the person's age-based life expectancy factor and the age pension rate; anything above that amount can be treated as a gift or deprived asset for five years. Separately, the entry contribution affects whether the person is a homeowner for the assets test. If it exceeds the applicable extra allowable amount, the person is generally treated as a homeowner and the granny flat interest itself is not counted as an assessable asset. If it is equal to or below that amount, the person is generally treated as a non-homeowner and the entry contribution may remain assessable. The outcome should be checked with Services Australia before any assets are transferred.
What is the CGT position?
From 1 July 2021, eligible CGT events arising from the creation, variation or termination of a qualifying granny flat arrangement are disregarded, provided the statutory eligibility requirements are met. The concession does not exempt unrelated CGT events, including a later sale of the property by the owner. Tax advice specific to the parties' circumstances should be obtained before the arrangement is documented.
Should the granny flat agreement be in writing?
A written agreement is required for the federal CGT exemption and is strongly advisable for Centrelink purposes and for preventing disputes. Although Services Australia may accept an unwritten arrangement, proving its existence and terms can be considerably more difficult. The written agreement records the parties, the money or property transferred, the right of residence, contributions to outgoings, exit arrangements, dispute resolution and what happens if the family member dies, separates or becomes bankrupt.
What happens if the family member's marriage ends?
This is one of the most important risks. If the family member's marriage or de facto relationship ends, the family home in which the older person lives can become an asset in a family law property settlement. A well-drafted granny flat agreement, and consideration of ownership structures, help but do not eliminate this risk. Legal advice should address it explicitly before assets change hands.
What happens if the arrangement breaks down?
Family relationships change. The granny flat agreement should set out what happens if the older person needs to leave the home for aged care, if the family member wants to sell, if the relationship deteriorates, or if a party becomes bankrupt or dies. Without these terms, disputes can result in costly civil, equitable or family-law proceedings and the older person can be badly exposed.
Is a granny flat arrangement an elder-law risk?
It can be. Granny flat arrangements are a known area for elder financial abuse concerns because they typically involve the older person transferring a significant portion of their wealth to a person they trust, often without independent advice. Independent legal advice for the older person, separately from the family member receiving the benefit, is strongly recommended.
How does a granny flat interest interact with a Will and estate?
The older person's Will should be reviewed alongside the granny flat arrangement — for the treatment of the transferred assets, for the position of other children and dependants who may bring family provision (TFM) claims, and for the equalisation between beneficiaries. Powers of attorney should also be reviewed, so that the arrangement is honoured if capacity is later lost.
