Cohabitation Agreements

Cohabitation Agreements (also known as “prenups”) are a type of Binding Financial Agreement that may protect your interests in the event of a separation. They offer individuals in de facto relationships an agreed-upon way to separate assets and financial responsibilities in the event of a relationship breakdown.

What's the purpose of a cohabitation agreement?

A cohabitation agreement is more than just a piece of paper—it’s a legally binding document that sets out how you and your partner will manage your finances during your relationship and if things don’t go as planned.

This agreement provides clear, legally binding instructions on how you both will handle your financial resources now and in the event of a future separation.

It’s all about making sure there’s no confusion, so both parties know exactly where they stand.

Minimising risk for de facto couples

In the event of a relationship breakdown, de facto couples will have to divide both assets, debts, and parental responsibilities between them. By signing a binding financial agreement, you can ensure that this division is done in a way that is just and equitable.

Avoid losing property

A binding financial agreement will cover both separate and shared assets, so you can feel confident in your financial future. The agreement should clearly define what belongs to each partner individually and what will be considered joint property. This clarity helps avoid disputes over property division in case of a breakup.

Avoid becoming responsible for your partner's debt

When you divide personal assets in a separation, you are also at risk of receiving a portion of their debt. Pre-nuptial agreements (rather than simple, informal agreements) can protect you from this reality, ensuring you don’t become responsible for the financial issues of your former partner.

Minimise impact on children

Cohabitation agreements are especially important when you have children and start a new relationship or marriage. You want to protect what you’ve built financially, ensuring that your assets are secured for your children if things don’t work out.

Simply having a Will isn’t enough—especially if the relationship ends before you pass away. A cohabitation agreement provides that extra layer of protection, ensuring your finances are safeguarded.

How to create a binding financial agreement

To make this financial agreement enforceable by law, it’s important that both parties receive separate legal guidance under the Family Law Act 1975. Having legal guidance ensures that the agreement holds up in court and that neither party can later claim they were pressured into signing.

How to make it binding

For these agreements to hold up legally, each person needs to receive independent legal advice and have their own lawyer sign a Certificate of Independent Legal Advice. This step is crucial in making the cohabitation agreement legally binding under the Family Law Act 1975.

Signing under pressure? Think again

It’s also important to remember that you can’t force the other party to sign. If someone feels pressured, the agreement might later be set aside by the Family Law Court on the grounds of “duress.”

So, while cohabitation agreements are powerful tools for protecting your finances and ensuring your children are looked after, they must be entered into freely by both parties to stand the test of time.

What should you consider when setting up your financial agreements?

Consider how the agreement will work out long-term

When thinking about a cohabitation agreement, it’s important to consider how it might play out over time. While these agreements can provide clear, legally binding terms to protect your monetary resources and separate assets, they can also have unintended consequences.

Take this example: if you start the relationship in a stronger financial position but end up worse off, you might look back and wonder if signing that cohabitation agreement was the right move. The agreement, while meant to protect, could end up working against you if the circumstances shift.

What could change?

That’s why it’s important to think about the long-term impact. How might your respective financial circumstances change over time?

Are there provisions in the binding financial agreement that account for shifts in your financial situation? Considering potential changes to shared assets and future debt obligations is also vital.

What about fidelity?

In some cases, these agreements even include a “fidelity” clause, which is becoming more popular as concerns about infidelity grow. This clause can mean there is a different financial outcome at the end of the relationship based on whether there has been infidelity during the relationship. 

To make sure you’re fully protected, always seek independent legal advice before signing. This advice ensures that the agreement under the Family Law Act 1975 is not just fair now but remains fair in the years to come.

Case Study: Safeguarding Assets with a Cohabitation Agreement

Background: A couple in a de facto relationship decided to move in together. One partner owned a business and a home, while the other had savings but was concerned about potential debt risks.

Solution: They drafted a cohabitation agreement to clearly define their separate and shared assets. The agreement ensured that the home and business remained separate property and outlined how they would handle joint expenses and any future debts.

Outcome: When the relationship ended, the agreement allowed for a smooth and conflict-free separation. Both parties retained their respective assets, and financial responsibilities were clear, demonstrating the agreement’s value in protecting individual interests.
