Overview: What Is a Prenuptial Agreement in Australia?

A prenuptial agreement (or prenup) is a written agreement between two people about how their property, financial resources and spousal maintenance will be dealt with if their relationship breaks down. In Australia, a prenup is a type of binding financial agreement (BFA) made under the Family Law Act 1975 (Cth).

When a binding financial agreement covers a matter, the court's usual power to divide property and order maintenance does not apply to that matter (ss 71A and 90SA). Instead of a judge deciding what is fair, the agreement you both signed decides it.

Book a consultation to discuss whether a prenuptial agreement is right for your situation.

Prenup, BFA or Financial Agreement: One Document, Several Names

You will see several names for the same thing:

  • Prenuptial agreement or prenup: the everyday name for an agreement made before marriage.
  • Binding financial agreement or BFA: the common legal name. The Act itself calls it a "financial agreement".
  • Postnuptial agreement: an agreement made during a marriage.
  • Cohabitation agreement: the everyday name for an agreement made before a couple moves in together.

The section of the Act under which an agreement is made determines the applicable rules.

What a Prenup Can and Cannot Cover

A prenup can deal with:

  • Property each of you owns now, such as a home, investments or a business
  • Property either of you acquires later in the relationship, including a future inheritance (s 90B(2)(a))
  • Superannuation, which the agreement can treat in the same way as property (s 90XH)
  • Interests in family trusts and companies
  • Spousal maintenance during the relationship or after it ends

A maintenance clause must name the person it provides for and state the amount or value. Otherwise it is void (s 90E; s 90UH). A court can also still order maintenance if, when the agreement took effect, one of you could not support yourself without an income-tested pension or allowance (s 90F; s 90UI).

A prenup is not the place to settle where your future children will live. If a court is ever asked to make parenting orders, your child's best interests are the paramount consideration (s 60CA). Child support is dealt with under its own rules. You can read more on our child support page.

Book a consultation to discuss what your agreement should cover.

Who Should Consider a Prenuptial Agreement?

A prenup is worth considering whenever one or both of you is bringing something into the relationship you want to keep clear. Common situations include:

  • You own a home or investment property before the relationship begins
  • You own a business, or hold an interest in a family company or trust
  • You expect to receive an inheritance, or your parents have helped with a deposit
  • You have children from an earlier relationship and want to provide for them
  • You have been through a property settlement before
  • You and your partner have very different financial positions or incomes

Without an agreement, the court can make orders about all the property of either of you, including property owned before the relationship began (s 79). What you brought in is taken into account, but there is no rule that you keep it. You can read how that process works on our property settlement page.

A prenup is also not only for the person with more assets. Both of you get certainty, and both of you get independent legal advice before you sign.

Agreements Before and During Your Relationship

The Family Law Act has separate provisions for married and de facto couples, and for agreements made at different stages. This page covers agreements made before or during a relationship.

Book a consultation to find out which type of agreement suits your relationship.

Before Marriage: Prenuptial Agreements

Couples who are planning to marry can make a financial agreement under section 90B. It can deal with property you own when you sign, and property either of you acquires later, before any divorce.

If your agreement deals with superannuation, those terms only take effect once you marry. If the wedding does not go ahead, they never apply (s 90XH(4)).

During Marriage: Postnuptial Agreements

Married couples can make a financial agreement under section 90C. A postnuptial agreement suits couples who did not sign one before the wedding, or whose circumstances have changed. For example, one of you may have received an inheritance, started a business or bought property with help from family.

A section 90C agreement can also be made after a marriage has broken down. That is a property settlement, not a prenup, and it is covered on our property settlement page.

De Facto Couples: Cohabitation Agreements

De facto couples have the same ability to make a binding financial agreement, under Part VIIIAB of the Act:

  • Before you move in together: a section 90UB agreement, often called a cohabitation agreement or a de facto prenup
  • While you live together: a section 90UC agreement

You do not need to have been together for any set time before you can sign a cohabitation agreement. That matters because your partner can usually apply for a property settlement once you have lived together for 2 years, or sooner in some cases, such as where there is a child of the relationship or the relationship was registered (s 90SB). The simplest time to sign is before you move in, or soon after. Whether you are in a de facto relationship at all depends on the circumstances (s 4AA). Our de facto relationships page explains how that is decided.

If you later marry each other, your de facto agreement stops being binding (s 90UJ(3)). This is the step many couples miss. If you signed a cohabitation agreement and are now engaged, you need a new agreement made under the marriage provisions (s 90B or s 90C). Otherwise the agreement you relied on may not protect you once you are married.

Already Separated?

If your relationship has already ended, the agreement you need is a property settlement. We cover binding financial agreements made after separation, and how they compare with consent orders, on our property settlement page.

What Makes a Prenup Legally Binding

A financial agreement is binding only if every one of these steps is completed (s 90G for married couples; s 90UJ for de facto couples):

  1. It is in writing and signed by both of you, and by anyone else who is a party to it.
  2. Each of you receives independent legal advice before signing. The advice must cover how the agreement affects your rights, and its advantages and disadvantages to you at the time.
  3. Each lawyer signs a statement confirming that advice was given.
  4. A copy of each statement is given to the other party or to their lawyer.
  5. The agreement has not been ended or set aside by a court.

The agreement must also state the section of the Act it is made under.

When the Agreement Takes Effect

Signing a prenup does not usually change who owns what today. The parts that divide property on a breakdown have no effect until one of you signs a separation declaration (s 90DA; s 90UF). This is a written statement that you have separated and there is no reasonable likelihood of getting back together. For a married couple that requirement falls away on divorce. For any couple, it falls away if one of you dies.

Why Prenups Fail

A prenup can be challenged, but a court can set one aside only on the grounds listed in the Act (s 90K; s 90UM). Many of those grounds come down to how the agreement was made:

  • Formalities missed: a missing or unexchanged advice statement can leave the agreement not binding (s 90G; s 90UJ).
  • Pressure or poor timing: an agreement signed under duress or undue influence, or obtained by unconscionable conduct, can be set aside (s 90K(1)(b), (e); s 90UM(1)(e), (h)).
  • Incomplete disclosure: failing to disclose something material counts as fraud under the Act (s 90K(1)(a); s 90UM(1)(a)).
  • Changes involving children: a material change affecting a child's care that would cause hardship (s 90K(1)(d); s 90UM(1)(g)).
  • Drafting that cannot be carried out: terms that have become impracticable, or superannuation that cannot be split (s 90K(1)(c), (g); s 90UM(1)(f), (j)).

We draft every agreement to reduce these risks. No lawyer can promise a prenup will never be challenged, but a well-made agreement gives the person challenging it far less to work with.

Book a consultation to have your agreement prepared or reviewed.

Prenups, Wills and Protecting an Inheritance

A prenup decides what happens to your property if your relationship ends. Your will decides what happens when you die. Most people who need a prenup should look at their will too.

  • Your agreement binds your estate: a binding financial agreement continues to operate after the death of either of you, and binds that person's executor or administrator (s 90H; s 90UK). Your agreement and your will need to be consistent.
  • Blended families: a prenup can provide that the property you want your children to receive stays yours if your relationship ends. Only your will can leave it to them.
  • Future inheritances: a prenup can deal with an inheritance you have not yet received (s 90B(2)(a); s 90UB(2)(a)).

Family Law and Wills Specialists Under One Roof

VRT Lawyers has Accredited Family Law Specialists, including Partner Daniella Ruggero, and an Accredited Wills and Estate Law Specialist in the same firm. When you make a prenup with us, we can review your will and estate plan at the same time, so both documents work towards the same result. You can read more about making a will and estate planning.

Been Asked to Sign a Prenup?

If your partner has given you an agreement to sign, you need your own lawyer. The law requires each of you to receive independent legal advice before signing (s 90G; s 90UJ), and the lawyer who prepared the agreement acts for your partner, not for you.

We can advise you on:

  • What the agreement means for you, in plain English
  • What you would be giving up compared with a property settlement without one
  • Whether the financial disclosure is complete
  • Changes to ask for before you sign

Take the time you need. If you feel pressured, or the wedding date is close, tell your lawyer. That is exactly the situation the law on unconscionable conduct and undue influence is designed for.

VRT Lawyers can act for only one of you. Your partner will need to see a lawyer from another firm.

Our Prenuptial Agreement Process

  1. Initial consultation. We discuss your circumstances and what you want the agreement to achieve, and confirm which section of the Act applies.
  2. Financial disclosure. You and your partner each set out your assets, debts, income, superannuation and expected inheritances, and exchange them through your lawyers.
  3. Drafting and negotiation. We prepare the agreement and negotiate the terms with your partner's lawyer.
  4. Independent advice and signing. Each of you receives written advice from your own lawyer. You sign, the lawyers sign their statements, and the statements are exchanged.
  5. Storage and review. Keep the signed agreement somewhere safe, with your will. We recommend reviewing both after major life events such as marriage, children, an inheritance or a new business.

FAQs

Are prenups legally binding in Australia?

Yes, if they meet the requirements of the Family Law Act 1975 (Cth). Both of you must sign, and each of you must receive independent legal advice before signing. Each lawyer must also provide a signed statement, which is given to the other party (s 90G; s 90UJ). An agreement that misses a step may not be binding.

Can a prenup be overturned?

Yes, but only on the grounds set out in the Act (s 90K; s 90UM). These include fraud or failure to disclose, duress or undue influence, unconscionable conduct, impracticability, and a material change in circumstances affecting a child that would cause hardship. No prenup is beyond challenge, which is why how it is made matters as much as what it says.

Can a prenup be changed or cancelled?

Yes, but not by simply agreeing between yourselves. A financial agreement can be ended only by a new financial agreement that terminates it, or by a written termination agreement (s 90J; s 90UL). Either needs the same independent legal advice and signed statements as the original. If your circumstances have changed, the usual approach is a new agreement that replaces the old one.

Can cheating void a prenup?

No. Infidelity is not one of the grounds for setting aside a financial agreement under s 90K or s 90UM. Australian family law is also "no fault": a divorce depends only on the marriage having broken down irretrievably (s 48).

Can de facto couples get a prenup?

Yes. De facto couples can make a binding financial agreement before moving in together (s 90UB) or during the relationship (s 90UC). If you later marry each other, the de facto agreement stops being binding (s 90UJ(3)), so you will need a new one.

Is a prenup signed overseas valid in Australia?

Not automatically. To be a binding financial agreement here, an agreement must state that it is made under the relevant section of the Family Law Act (s 90B(1)(b); s 90UB(1)(c)). It must also meet the signing and independent advice requirements in s 90G or s 90UJ. If it does not, it is not a binding financial agreement under Australian law.

For de facto couples there is a further rule. A de facto agreement can only be made under the Act if you both lived in a participating Australian state or territory when you made it (s 90UA). If you have an agreement from overseas, have it reviewed. You may need a new Australian agreement.

Can my partner claim the house I bought before we married?

Without an agreement, the house can be included in a property settlement. The court can make orders about all the property of either party, including property owned before the relationship (s 79; s 90SM for de facto couples). Your contribution in bringing it into the relationship is taken into account, but there is no rule that you keep it. A prenup can set out in advance that it stays yours.

Can a prenup protect a future inheritance?

Yes. A prenup can deal with property either of you acquires later in the relationship, including an inheritance you have not yet received (s 90B(2)(a); s 90UB(2)(a)). It should be drafted to cover what happens if the inheritance is later mixed with joint assets, such as being used to pay down the family home.

Can we make a binding financial agreement without lawyers?

Not one that is binding in the ordinary way. Independent legal advice for each of you, and a signed statement from each lawyer, are requirements of the Act (s 90G; s 90UJ). If a step was missed, a court can still declare the agreement binding, but only if it is satisfied it would be unjust and inequitable not to (s 90G(1A); s 90UJ(1A)). That means going back to court, which is what the agreement was meant to avoid.

What are the downsides of a prenup?

Each of you needs your own lawyer, and you will both need to make full financial disclosure. The agreement can turn out less favourable to one of you than a court-ordered settlement would have been, which is why independent advice is required. It also needs reviewing as your life changes, and it can still be challenged on the grounds in the Act.

Is asking for a prenup a red flag?

Not in itself. Many couples see it as an honest conversation about money before they commit. What causes problems is how it is raised. Raising it early, with time for both of you to get advice and ask for changes, makes the agreement fairer and much harder to challenge later.

How long before the wedding should we sign a prenup?

The Act does not set a minimum period. But an agreement signed close to the wedding is more exposed to a challenge for pressure or unconscionable conduct.

The leading case is Thorne v Kennedy [2017] HCA 49. About 11 days before the wedding, the bride was told it would not go ahead unless she signed. She first saw the terms of the agreement the next day. Her own lawyer advised her not to sign. She signed four days before the wedding, and signed a substantially identical agreement after it. The High Court set both agreements aside for unconscionable conduct, and a majority also found undue influence.

The High Court listed factors that may be prominent when deciding whether a prenup or postnup was signed under undue influence:

  • Whether the agreement was offered on the basis that it could not be negotiated
  • The emotional circumstances, including any threat to end the engagement or marriage
  • Whether there was time for careful reflection
  • The nature of the relationship
  • The relative financial positions of the couple
  • The independent advice received, and whether there was time to reflect on it

The lesson is that independent advice alone does not save an agreement signed under pressure. The time to start is well before the wedding is booked, not in the weeks before it.
