Prenuptial Agreements in Australia

What is a prenup?


A prenuptial agreement in Australia, commonly known as a prenup, is a document that governs how your assets will be distributed in the event that you and your partner separate.

It lists all the property and any debts that each person owns, and then each person’s property rights after the marriage.

Essentially, it is a written contract, establishing each person’s financial standing and how finances will be split after a separation.

In Australia, the legal term for a prenup is a binding 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 would not be able to enter into a prenup with a mistress if you already have a prenup with your wife.


When can a binding financial agreement be made?


A binding financial agreement can be created at any time.

It can be made before you enter into a relationship, to protect your assets in the event that you break up, or it can be during the relationship or at the termination of the relationship.

Despite the familiar “prenuptial” name, financial agreements do not 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.

However,  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.


Why would you make a binding financial agreement?


Couples do not create binding financial agreements because they expect a separation or divorce, rather they prepare one just in case, to avoid any confusion or problems later in the future.

With the increasing rate of divorces, couples are aware that they may have long and expensive legal disputes in the future, so they arrange binding financial agreements in advance, to avoid these legal costs and any lengthy and expensive interference from the court.

Furthermore, people are generally marrying later in their lives now, choosing to focus on their careers and accumulate assets before they settle down.

By the time they do marry, parties usually have a portfolio of assets or property that they may wish to protect, and they create binding financial agreements to do so.


What can be included in a binding financial agreement?


There are several things that can be included in a binding financial agreement:

  1. Firstly, what is included in a binding financial agreement is disclosure of financial resources, assets, and liabilities that each party brings to the marriage.
  2. Secondly, a binding financial agreement details how these assets and debts would be divided between the parties in the event that they separate 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.
  3. 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.
  4. The agreement can include provisions for spousal maintenance as well. 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.
  5. The agreement can also include options relating to possible future events. 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 is all good and well to write out and sign a prenup, but if it is not legally valid then the court still has the power to make different financial orders.

There are strict legal guidelines relating to binding financial agreements:

  1. The first begins with advice from a lawyer. Each party must obtain independent legal advice from a lawyer practicing in the Australian jurisdiction. This is a requirement for the binding financial agreement to be valid.
  2. Secondly, the prenuptial agreement must be in writing.
  3. 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.
  4. The prenup must contain a full disclosure, including all assets and their full value, of each party’s financial position.
  5. 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.

Different types of financial agreements

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:

  1. If you are a couple who is wanting to live together in a de facto relationship but are not living together yet, you would enter into a Section 90UB Cohabitation Agreement.
  2. If you are a couple living together in a de facto relationship, you would enter into a Section 90UC Cohabitation Agreement.
  3. If you are a couple who is intending to marry, you would enter into a Section 90B Pre-Nuptial Agreement.
  4. If you are a couple who is already married, regardless of whether you intend to stay married or separate, you would enter into a Section 90C Post-Nuptial Agreement.
  5. If you are a couple who has 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
  6. If you are 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 you should look for when hiring a prenup lawyer Sydney


When hiring a prenup lawyer, you will want to know that if they are a specialised divorce lawyer that has previous experience drafting prenups.

Prenups don’t have the best reputation in Australia.

This is largely because many legal practitioners may ‘dip their toes’ in the world of prenups and offer it as a service, but aren’t familiar with the latest laws surrounding them.

It is really important that you engage a law firm that is proficient in prenups, and have the experience to assure you that the agreement will be binding.

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 binding financial 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:

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

What Legislation Covers binding financial agreements in Australia?

Binding Financial 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.
