Prenuptial Agreements in Australia


What is a prenup?

For many couples, a prenuptial agreement in Australia, commonly known as a prenup, is a document that explains how your assets will be distributed in the event you’re separate from your partner or spouse.

A prenup lists all of the property and all of the debts that each person owns. It then specifies what each person’s property rights will be after the marriage.

They can be created before you enter into a relationship before you enter into a marriage, whilst you are in a relationship or marriage, or at the end of a relationship or marriage.

It is a written contract that sets out each person’s financial standing and the way they have decided their finances would be split in the event of a relationship breakdown.

The correct term for a prenuptial agreement in Australia is a binding financial agreement.

Despite the familiar “prenuptial” name, financial agreements do not actually have to be signed prior to the wedding. They can be signed by couples intending to be married, couples already married, de facto couples moving in together and de facto couples who have already been in a relationship for a long time.

Couples do not make prenups because they expect to divorce; rather, a prenuptial agreement provides a certain level of assurance for the “just in case” scenario.


Are prenuptial agreements in Australia a good idea?

Prenuptial agreements in Australia are becoming more popular for a whole range of reasons.

With an increasing divorce rate, couples are wary of the possibility that they may have long and expensive legal disputes in the future.

Another reason is that people are generally marrying later in their lives, choosing to focus on their careers and accumulate assets before they settle down.

By the time they do marry, the parties may have a portfolio of property that they would like to protect.

Prenuptial agreements make this easy to do.

One of the biggest dilemmas in a divorce is deciding how to divide property and assets.

Many prenuptial agreements are entered into to make this process a lot simpler.

Couples do not want any interference from the courts, and would rather determine their own future.

What can be included in a prenuptial agreement?

Prenuptial agreements in Australia start with a disclosure of the financial resources, assets, and liabilities that each party is bringing to the marriage.

The prenup then details how these assets and debts would be divided in the event of separation or divorce. This hypothetical division of assets can include several different types of assets, such as cash, property, superannuation savings, inheritances, monetary gifts, pension entitlements, and businesses.

A prenup, therefore, protects the assets that each person wants to keep.

The agreement can also outline any obligations one or both parties might have to resolve debts and liabilities, both personal ones and those of the relationship.

Couples making a prenup may also choose to include provisions for spousal maintenance. This is the money that one spouse pays to the other after their relationship has ended.

When all of this is agreed to and signed in a valid financial agreement, the prenup will prevent the court from making orders regarding the division of property if the two people separate or divorce.

However, one of the essential components of a prenup is the way it addresses all possible outcomes.

Couples should include options relating to possible future events in their prenuptial agreement.

The most obvious of these possible future outcomes is having children.

Having children in the relationship is considered a “material change” to the couple’s finances and poses a risk to the validity of the prenup if it has not already been addressed.

Mentioning children in a prenup, even by just mentioning the possibility of having children, improves the likelihood that the agreement will remain valid in the event of separation or divorce.


Binding financial agreements – are they really binding?

It’s all well and good to write out and sign a prenup, but if it is not legally valid then it becomes a waste of time and the court has the power to make different financial orders.

There are strict legal guidelines relating to prenups.

The process of getting a prenup begins with advice from a lawyer.

Each party must obtain independent legal advice from a lawyer practicing in the Australian jurisdiction.

The prenuptial agreement must be in writing.

It must be signed voluntarily by both parties, without coercion or duress. An example of coercion or duress would be one person in the relationship telling the other that they will not marry them if they do not sign the prenup. If someone signs the prenup on the day of the wedding, this is also considered as under duress.

The prenup must contain a full disclosure, including all assets and their full value, of each party’s financial position.

It must not be made on a fraudulent basis.

If any of these requirements are not fulfilled, the court has the authority to overturn the financial agreement.

As mentioned in the previous section, the court has the authority to overturn a prenuptial agreement if it made no provisions for children of the relationship.

Depending on the circumstances, the court may choose to enforce only part of the financial agreement.


Who can get a Binding Financial Agreement

Couples at any stage of their relationship can enter into a binding financial agreement.

Heterosexual or homosexual (de facto) couples can both enter into a prenup.

The types of Agreements and their relevant sections are the same for opposite or same-sex couples.

Both parties intending to enter into a prenup must ordinarily reside in Australia.

Each party must also get Independent Legal Advice from different lawyers working in different law firms.

The lawyers must also sign a certificate confirming that the advice, as required by the Family Law Act 1975 (Cth) was given to their client before their client signed the Agreement.

You cannot enter into a prenup if you are already in a valid prenup with another person.

For example, you wouldn’t be able to enter into a prenup with a mistress if you already have a prenup with your wife.


When can I enter into prenuptial agreements in Australia?

You may enter into prenuptial agreements in Australia at any point in your relationship.

Having a financial agreement in place ensures that you make your own rules about how you would like to split your assets in the event that you decide to separate in the future.

You do not need to have entered into a financial agreement before a relationship or marriage.

You can see a lawyer at any point to get it done.

This means you can get it done during a relationship, after your marriage, even after you separate.

Be mindful that both people in the relationship will need to receive independent legal advice to ensure that the financial agreement is valid.

It is not usually recommended that couples sign a financial agreement immediately before their wedding, as it could later be argued that the financial agreement was only signed because there was pressure on one side to pull out of the wedding.

In certain circumstances, if you enter into a financial agreement before having children, and separate and try to rely on the financial agreement after having children, a court may say that the financial agreement is no longer binding on both parties.

There are different types of financial agreements depending on the nature of your relationship.

It is important that you make an agreement that is suitable for your circumstances.

The different types of financial agreements depend on the type of relationship you have and at what stage you are making the financial agreement:

  • Wanting to live together as a de facto couple and are not yet living together, you would enter into a Section 90UB Cohabitation Agreement
  • Living together as a de facto couple, you would enter into a Section 90UC Cohabitation Agreement
  • Intending to marry, you would enter into a Section 90B Pre-Nuptial Agreement
  • Already married, regardless of whether you intend to stay married or separate, you would enter into a Section 90C Post-Nuptial Agreement
  • Separated, you would enter into a Separation Agreement. There are different forms of Separation Agreements.
  • Section 90UD is for a de facto separation
  • Section 90D is for separation if the parties were married
  • Already divorced, and you want to document property settlement matters in a Binding Financial Agreement, you would enter into a Section 90C Divorce Agreement

What sort of legal advice will you receive?

Making an appointment with a prenup lawyer is one of the legal requirements of drafting and signing prenuptial agreements in Australia.

Each party must obtain legal advice from a different lawyer that specialises in prenuptial agreements in Australia.

The lawyers will advise their respective clients of the prenuptial agreement’s effect on their rights, along with the advantages and disadvantages that signing the prenup will have for each party.

Furthermore, legal advice includes being told exactly how necessary the agreement is for that person and whether the proposed division of property detailed in the prenup is just and equitable for them.

In order to receive legal advice tailored to their situation from the very beginning, each party should prepare their basic financial and personal information for the lawyer they are seeing.

This information includes:

  • A list of their assets and liabilities (including superannuation, businesses, pension entitlements) with estimated values, and those of their partner
  • The details of their employment and salary, and those of their partner
  • Most recent tax return and bank statements
  • How they would want their property, superannuation, spousal maintenance and child support to be divided in the event of a relationship breakdown
  • Full name, date of birth, contact details

What Legislation Covers prenuptial agreements in Australia?

Prenuptial Agreements in Australia are covered separately in the Family Law Act 1975.

Sections 90B to 90KA set out the legislation for married couples and financial agreements.

There are different sections about agreements made before and during a marriage, as well as after divorce orders.

The legislation provides the rules for setting aside financial agreements, the elements that make them legally binding and enforceable and even what happens if one party to the financial agreement dies.

If a couple made a financial agreement and then one of the parties dies when the agreement is still in effect, the agreement continues to operate.

It is now binding on the legal personal representative of that person’s estate.

Sections 90UB to 90UN relate to financial agreements and de facto couples.

These sections are very similar to those relating to married couples. Legislation regarding financial agreements made after the breakdown of the de facto relationship is included instead of after divorce.

The Act is very specific, for example in relation to the mention of children in prenuptial and financial agreements.

Sections 90E and 90UH provide the information for married and de facto couples respectively about child support and spousal maintenance. Mentions of these in prenups are only legally valid if the person to be supported (the spouse or child) is named and the amount provided for them is specified.

Case Studies of prenuptial agreements in Australia

The following two cases show the very strict legal intricacies of making prenuptial agreements in Australia:

Sullivan & Sullivan 2011

In this case from Melbourne in August 2011, the husband, Mr Sullivan, sought a declaration from the court that the financial agreement signed between him and his former wife, Ms Sullivan, was valid and enforceable.

He sought a rectification to change an error in the document.

The signed document stated that it was “entered into under s90B” of the Family Law Act 1975. This section pertains to financial agreements signed before marriage. However, the husband had signed the agreement after the couple’s wedding day.

The husband wished this passage to be changed to “entered into under s90C,” which is the section for financial agreements made during a marriage.

The wife, on the other hand, opposed the orders her former husband sought.

She stated that she had been put under undue pressure to sign the agreement, which, as she detailed in her affidavit, had been presented to her ten days before the parties’ wedding.

According to the wife, the husband insisted that she sign the agreement, despite the fact that one of the solicitors she went to advised her against it, and threatened to cancel the wedding if she did not.

The wife signed the agreement on the 11th of April 2003.

The couple were married on the 13th of April and the husband signed the agreement three days later, on the 16th of April.

The judge hearing this case in 2011 ordered that the financial agreement is unenforceable as it is not a “financial agreement” under the definitions in s90B or s90C.

The agreement is not binding under s90G of the Act.

Raleigh & Raleigh 2015

In a similar case from Sydney in 2015, the court ordered the financial agreement to be set aside.

The wife had signed the agreement eight days before the birth of her and the husband’s first child, after conferring with a solicitor for 15 minutes.

She and the husband signed the agreement in October 2003.

The wife stated that she did not receive the requisite legal advice, that the husband had engaged in unconscionable conduct by exercising undue influence on her and that a material change in circumstances relating to the couple’s two children has made the agreement inequitable.

The judge dismissed the husband’s application and declared that the financial agreement was not legally binding.

The wife now is able to apply for property orders.
