Can My Spouse Claim My Inheritance in a Divorce in Australia?
“Will my ex walk away with my inheritance?” It is one of the most common fears people bring to a family lawyer, and for good reason.
An inheritance often carries emotional weight and represents something a parent or grandparent intended for you. The honest answer is that it depends. An inheritance is not automatically protected, but it is not automatically up for grabs either.
This guide explains when an inheritance can be included in a property settlement in Australia, what factors the court looks at, and the practical steps you can take to protect what you have received.
Is an Inheritance Automatically Treated as Marital Property in Australia?
No. There is no rule in Australia that automatically includes or excludes an inheritance from a property settlement. Instead, the Federal Circuit and Family Court of Australia looks at the whole financial picture under the Family Law Act 1975 (Cth) and decides what is just and equitable.
This surprises many people who assume an inheritance is either always safe or always shared. In reality, an inheritance is treated as one contribution among many.
Whether it stays in your hands, gets divided, or affects the split of other assets depends on when you received it, how you used it, and the needs of both parties going forward. Because there is no automatic protection, the outcome is highly fact-specific.
When Can a Spouse Include Your Inheritance in a Property Settlement Claim?
A spouse can seek to include your inheritance when it has become part of the shared financial life of the marriage. It can also be included when the overall settlement would not be fair without accounting for it. The court has broad discretion here.
Several factors push toward inheritance being shared or kept separate:
| Factor | More likely to be shared | More likely to stay yours |
| Timing | Received early in a long marriage | Received late or after separation |
| Use of funds | Mixed into joint assets | Kept in a separate account |
| Family home | Used to pay down the mortgage | Never touched shared property |
| Other party’s reliance | Both benefited over the years | The other party never depended on it |
The key question is how connected the inheritance became to the joint financial life of the marriage. The more entangled it is, the harder it becomes to protect.
What Happens If You Spent or Invested the Inheritance During the Marriage?
If you spent or invested your inheritance in shared assets, it generally becomes much harder to protect. Once inheritance money is used for joint purposes, it loses its separate character and blends into the common asset pool the court divides.
Consider a common example. You inherit a sum and use it to reduce the mortgage on the family home. That money has now benefited both of you and is tied up in a shared asset.
The court is unlikely to hand it back to you dollar for dollar. Instead, it will usually recognise your inheritance as a significant financial contribution you made, which can weigh the split in your favour. It does not guarantee you get the full amount back.
The opposite is also true. If you kept the inheritance in a separate account, did not use it for shared expenses, and the other party never depended on it, you have a much stronger argument that it should be treated as yours.
How you handle the money after you receive it often matters more than the fact that you received it. This is a core part of any property division in separation, and it is where good record-keeping pays off.
How Can You Protect an Inheritance Before or During a Marriage?
The most reliable way to protect an inheritance is to put a formal agreement in place. A Binding Financial Agreement (BFA) lets you and your partner agree in advance how specific assets, including an inheritance, will be treated if the relationship ends.
When properly drafted with independent legal advice for both parties, a BFA can quarantine an inheritance from a future property settlement. You have options at different stages:
- Before marriage or cohabitation: a prenuptial agreement, which is a type of BFA, can set out that any inheritance you receive remains yours.
- During the relationship: a BFA can be entered into at any time to deal with an inheritance you have received or expect to receive.
- In how you manage the money: keep the inheritance in a separate account, avoid using it for joint assets, and keep clear records of where it came from.
Practical steps and legal agreements work best together. A BFA gives you legal certainty, while careful handling of the money supports your position if the agreement is ever tested. You can read more about how Binding Financial Agreements work and whether one suits your situation.
Does an Inheritance Received After Separation Count in a Property Split?
The short answer is, yes. Many people assume that once they have separated, anything they inherit is automatically theirs. That is not how it works in Australia.
An inheritance received after separation is generally treated more favourably to the recipient than one received during the relationship, but it is not automatically excluded from the property pool. The court’s approach is highly discretionary and depends on the facts of the case.
When determining a property settlement under the Family Law Act 1975 (Cth), the court first identifies the parties’ property at the date of the hearing, not the date of separation. That means an inheritance received after separation is ordinarily part of the property available for consideration.
However, inclusion in the property pool does not mean it will be divided equally—or at all.
An inheritance received after separation is generally viewed as a post-separation financial contribution made solely by the recipient. However, the court can consider it when assessing future needs. If one party has just received a substantial inheritance and the other has limited resources, that difference in financial position can influence how the remaining assets are divided. So while a post-separation inheritance is often better protected, it is not automatically off-limits.
What Should You Do If You Are Worried About Protecting an Inheritance?
If you are worried about protecting an inheritance, the most important step is to get advice early, before you make decisions that are hard to undo. Small choices, like which account the money goes into, can have a large effect on how the inheritance is treated later.
A few practical measures can strengthen your position:
- Keep it separate. Hold any inheritance apart from joint accounts and shared assets.
- Keep records. Document what you received, when, and from whom.
- Avoid joint use. Do not use the funds for shared purposes if you want to preserve their separate character.
- Get advice on a BFA. Speak with a family lawyer about whether a Binding Financial Agreement is right for you.
Every situation is different, and the earlier you act, the more options you tend to have. If separation is already on the horizon, understanding how property division works will help you make informed choices.
