Cohabitation Agreement (Australia)

A Cohabitation Agreement in Australia records how a couple agree to divide their property and finances if the relationship ends, intended to be binding under the Family Law Act 1975 (Cth) Part VIIIAB.

In Australia, cohabitation agreements are particularly important because of the legal rights that arise under Australian de facto relationship law. Under Part VIIIAB of the Family Law Act 1975 (Cth), de facto couples who have cohabited for at least two years — or who have a child together, or where one party has made a substantial contribution to the relationship — may apply to the Federal Circuit and Family Court of Australia for property division orders and maintenance orders. The Property (Relationships) Act 1984 (NSW) similarly grants property adjustment rights to de facto partners after two years in NSW.

A Cohabitation Agreement typically addresses: which property each party owns separately (including pre-relationship property and property acquired by gift or inheritance); how jointly acquired property during the relationship will be owned; how shared household expenses will be split; how any joint bank account will operate; and what happens to property and the shared residence on separation.

A Cohabitation Agreement that meets the requirements of a Binding Financial Agreement under sections 90UC or 90UD of the Family Law Act (including the requirement that each party receives independent legal advice from a separate solicitor) will be legally binding and can remove the court's jurisdiction to make property orders about the covered matters.

The legal framework governing the Cohabitation Agreement (Australia) in Australia draws on several key statutes and regulatory bodies. Under Australian law, the Privacy Act 1988 (Cth) and Australian Privacy Principles (APPs) govern personal data in this document. The Australian Consumer Law (Schedule 2, Competition and Consumer Act 2010) provides consumer guarantees under Sections 51-54. The Federal Circuit and Family Court of Australia has jurisdiction over family law matters under the Family Law Act 1975 (Cth). The Australian Financial Complaints Authority (AFCA) handles consumer financial disputes. State and territory Magistrates Courts handle small civil claims. Parties executing a Cohabitation Agreement (Australia) in Australia should confirm the document reflects current law, including any amendments enacted since the original drafting date. Part VIIIAB of the Family Law Act 1975 (Cth) sets the foundational requirements.

A Cohabitation Agreement is relevant for any unmarried couple who are moving in together or who are already living together and wish to clarify their financial arrangements.

Couples with significant separate assets — such as property, investments, a business, or superannuation — benefit from a clear written record of what they each own separately and how they intend to manage jointly acquired assets. Without clarity, these assets can become the subject of dispute if the relationship ends.

Couples who have children from previous relationships should consider a Cohabitation Agreement to protect each party's ability to provide for those children from their separate assets, and to prevent those assets from becoming subject to de facto property claims.

Couples at the start of their relationship who are moving in together benefit from addressing financial arrangements before any issues arise. It is easier to agree on fair terms at the beginning of a relationship than after years of cohabitation and intermingled finances.

Couples who have been living together for some time but have not addressed their financial arrangements formally can use a Cohabitation Agreement to document their existing arrangements and clarify their intentions for the future.

A Cohabitation Agreement becomes increasingly important after two years of cohabitation, because at that point de facto property rights under the Family Law Act 1975 (Cth) may be fully available to both parties. Any agreement entered into before or early in the relationship provides a clearer record of the parties' pre-relationship assets.

Parties in Australia should prepare a Cohabitation Agreement (Australia) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under Australian law, the Privacy Act 1988 (Cth) and Australian Privacy Principles (APPs) govern personal data in this document. The Australian Consumer Law (Schedule 2, Competition and Consumer Act 2010) provides consumer guarantees under Sections 51-54. The Federal Circuit and Family Court of Australia has jurisdiction over family law matters under the Family Law Act 1975 (Cth). The Australian Financial Complaints Authority (AFCA) handles consumer financial disputes. State and territory Magistrates Courts handle small civil claims. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A well-drafted Australian Cohabitation Agreement should contain the following key elements.

Identification of the parties and the effective date establishes who is bound by the agreement and when it takes effect. Both parties should be identified by their full legal names and residential addresses.

A clear description of the shared residence — including the address and the nature of the tenancy or ownership — is essential. If one party owns the property, the agreement should address what rights (if any) the other party has in relation to the property during and after the relationship.

Full and frank disclosure of each party's separate property is important for the agreement to have legal credibility. Each party's pre-relationship assets, and any assets received as gifts or inheritances during the relationship, should be scheduled in annexures. Failure to disclose material assets is a ground on which a court might disregard an agreement in subsequent proceedings.

The provisions about jointly acquired property should clearly state how property purchased together during the relationship will be owned — whether as joint tenants, tenants in common in equal shares, or in proportions reflecting financial contributions.

Financial arrangements covering joint accounts and shared expenses should specify what expenses are shared, how they are divided (equally, proportionately to income, or otherwise), and how any joint bank account is to be operated and divided.

Separation and termination provisions should address the notice period required to end the agreement, how long a party has to vacate the shared residence, and how property will be divided on separation.

A de facto relationship acknowledgment informs both parties of their rights under Australian de facto legislation, including the Family Law Act 1975 (Cth) Part VIIIAB. This acknowledgment demonstrates informed consent.

Independent legal advice is strongly recommended before signing. For the agreement to operate as a Binding Financial Agreement under the Family Law Act, independent advice is mandatory.
