A ‘prenuptial agreement’ or cohabitation agreement, also referred to as a Financial Agreement, is a legal contract made by two individuals prior to their marriage or de facto relationship. The purpose of a prenup is to establish the financial arrangements that will apply in the event of separation or divorce. It covers the distribution of assets, liabilities, and other financial matters, ensuring that both parties are clear about their rights and responsibilities.
In Australia, where more than one in three de facto relationships and marriages end, prenuptial agreements have become increasingly important. They serve as a precautionary measure, offering financial security and reducing the potential for disputes in the unfortunate event of a relationship breakdown.
Who Can Enter Into A Prenuptial Agreement In Australia?
Under the Family Law Act 1975, both heterosexual and same-sex couples are able to make legally binding financial agreements regarding their property. A couple does not need to have significant financial assets to enter into a prenuptial agreement. Even individuals with modest property or financial interests can benefit from the clarity and protection that a prenup offers.
A prenuptial agreement helps establish a clear understanding of how assets and liabilities will be divided in case of separation. It is particularly useful for couples entering a marriage or de facto relationship where one or both partners have substantial assets, a family business, or other complex financial matters. However, the benefits are not limited to such circumstances—any couple can use a prenup to protect their interests and avoid potential conflict.
What Should Be Included In A Prenuptial Agreement?
A prenuptial agreement typically addresses both separate property and joint property. Separate property refers to assets that each partner owned before entering the relationship and any assets acquired during the relationship that are clearly designated as separate. This can include inheritances, family businesses or significant personal assets.
Joint property refers to assets that both partners have acquired during their relationship, such as a family home, investments or superannuation and retirement funds. A prenup outlines how these assets will be allocated in the event of separation or divorce.
In addition to property division, a prenup can address other important financial matters, such as spousal maintenance (also known as spousal support), which may include provisions for one partner to support the other financially in the event of separation. Prenups can also cover the distribution of debts, business interests and other financial matters, ensuring that all aspects of a couple’s financial life are addressed.

The Legal Status Of A Prenuptial Agreement
Prenuptial agreements are legally recognised under the Family Law Act 1975 – as family law financial agreements. However, for a prenup to be legally binding, both parties must meet certain conditions.
Both partners must receive independent legal advice before entering into a prenup. This means that each person must consult with their own lawyer, who will explain the legal implications and ensure that their rights are adequately protected.
Both parties must fully disclose their financial situation, including assets, debts, and any businesses owned. Non-disclosure of significant assets or financial interests can render a prenup unenforceable.
Furthermore, for a prenuptial agreement to be considered legally binding, it must be fair and reasonable. The terms must not be unduly biased in favour of one party, and the agreement must reflect the financial realities of both partners. If a court deems that a prenup is unfair or one party was coerced into signing it, the agreement may not be enforceable.However, a prenup can reflect the fact that one party brought more assets than the other into the relationship.
Creating A Legally Binding Prenuptial Agreement
It is essential to work with an experienced family lawyer to ensure that a prenuptial agreement is legally sound. A lawyer will help ensure that the terms of the agreement comply with the technical requirements of the Family Law Act and that both parties’ rights are fully protected. A prenup must be in writing, signed by both parties and executed voluntarily—free from any undue influence.
The agreement should be signed well in advance of the commitment to the wedding or de facto relationship. Rushed decisions or last-minute changes can lead to disputes over its fairness later on, particularly if one party feels pressured into signing.

Potential Consequences Of Not Having a Prenup
Without a prenuptial agreement, the division of assets and financial matters following a divorce or separation will be subject to the Family Law Act, and the outcome may be decided by a court. This can be a lengthy and costly process, and the distribution of assets may not align with each party’s expectations or intentions.
If no prenup is in place and an agreement cannot be reached, the courts will use the principles outlined in the Family Law Act to determine how property is divided. This process can lead to uncertainty, disputes and emotional stress, particularly if one partner feels that the distribution of assets is unfair.
Having a prenup in place helps to avoid such disputes and ensures that both parties have a clear understanding of how their assets will be divided. It can also help streamline the process if the relationship breaks down, allowing for a more amicable and efficient separation.
Seeking Professional Advice
Because prenuptial agreements are legally binding contracts with significant financial implications, seeking professional advice is crucial, and a legal requirement. A family lawyer who specialises in prenuptial agreements can guide you through the process, ensuring that your prenup is fair, enforceable, and tailored to your specific needs.
Each person must receive independent legal advice to ensure they fully understand the terms of their premarital agreement and their rights under the Family Law Act. If either party fails to receive independent legal advice, the agreement will not be considered valid.

Tips For A Successful Prenuptial Agreement
- Start Early: It is essential to begin the process of drafting a prenup well in advance of the wedding or relationship commencement. This will give both parties time to carefully consider their financial situation and discuss the terms of the agreement without feeling rushed.
- Be Transparent: Full disclosure of assets, debts, and financial interests is a critical part of the process. Both parties must be open and honest about their financial situation to ensure the prenup is legally enforceable.
- Seek Legal Advice: Engage an experienced family lawyer who specialises in prenuptial agreements to ensure the agreement is legally sound and reflects both parties’ interests.
- Customise the Agreement: Each couple has unique financial needs and circumstances. Tailor the prenup to your specific situation, considering factors such as children, businesses owned, and spousal maintenance.
- Prenuptial Agreements and Estate Planning: A prenuptial agreement can also be useful in estate planning. By addressing the division of assets in the event of a divorce or separation, a prenup can help protect individual property and ensure that each partner’s wishes are respected. It can also provide clarity on matters such as spousal maintenance, ensuring that both parties have a clear understanding of their financial rights and obligations.
Additionally, it is important to review and update a prenuptial agreement regularly, especially if your financial circumstances change significantly, such as the acquisition of new assets or the birth of children.
