De Facto Relationship Eligibility Checker
Wondering if your relationship qualifies as a de facto relationship under Australian law? Answer a few questions based on the factors courts consider under Section 4AA of the Family Law Act 1975.
What is a De Facto Relationship in Australia?
A de facto relationship is a legally recognised partnership between two people who live together on a genuine domestic basis but are not married. Under Section 4AA of the Family Law Act 1975 (Cth), de facto relationships in Australia are afforded similar legal protections to marriages, including rights relating to property settlement, spousal maintenance, and parenting arrangements.
De facto relationships apply to both opposite-sex and same-sex couples. Importantly, a person can be in a de facto relationship even if they are legally married to someone else, meaning Australian law recognises that complex relationship situations can exist simultaneously.
According to data from the Australian Institute of Family Studies, the proportion of couples in de facto relationships has increased significantly over the past three decades. In 1986, only 6% of all couples were cohabiting without marriage. By 2016, this figure had risen to 18%, reflecting changing social attitudes toward relationships and the increasing legal recognition of de facto partnerships.
Legal Definition: Section 4AA of the Family Law Act 1975
The Family Law Act 1975 provides the legal framework for determining whether a de facto relationship exists. Under Section 4AA, a de facto relationship is defined as a relationship between two people who:
- Are not legally married to each other
- Are not related by family (such as parent-child, siblings, or other family relationships)
- Live together on a genuine domestic basis as a couple
Factors Courts Consider When Determining De Facto Status
When deciding whether two people are in a de facto relationship, the Federal Circuit and Family Court of Australia considers the following circumstances under Section 4AA(2):
| Factor | Description |
|---|---|
| Duration of relationship | How long the couple has been together |
| Nature of common residence | Whether they share a home and how they live together |
| Sexual relationship | Whether a sexual relationship exists or existed |
| Financial interdependence | The degree of financial dependence or support between parties |
| Property ownership | Joint ownership, use, and acquisition of property |
| Mutual commitment | The degree of commitment to a shared life together |
| Relationship registration | Whether the relationship is registered under state or territory law |
| Care of children | Responsibilities for caring for children |
| Public reputation | Whether the relationship is publicly acknowledged |
Important Legal Principles
The law recognises several key principles regarding de facto relationships:
- No single factor is determinative — Courts weigh all circumstances and attach appropriate weight to each
- Cohabitation is not strictly required — Following the High Court decision in Fairbairn v Radecki [2022], living at the same address is not mandatory; couples may maintain separate residences while still being in a de facto relationship
- Multiple relationships can exist — A person can be in more than one de facto relationship at the same time
- Same-sex relationships are recognised — The Family Law Act explicitly recognises de facto relationships between people of the same sex
The Two-Year Rule: When Does a De Facto Relationship Exist?
Under Australian family law, couples who have lived together for a minimum of two years will generally meet the threshold for a de facto relationship under the Family Law Act 1975. However, this is not an absolute requirement.
Exceptions to the Two-Year Rule
The Federal Circuit and Family Court of Australia can make property settlement and maintenance orders for de facto relationships of less than two years if:
- A child was born from the relationship — If there is a child of the de facto relationship
- Substantial contributions were made — One party made significant financial or non-financial contributions, and refusing to make orders would result in serious injustice
- The relationship was registered — The relationship was registered under a prescribed state or territory law
Time Limits for Filing Claims
De facto couples must apply for property settlement or spousal maintenance orders within two years of the breakdown of their relationship. If this deadline is missed, special court permission (leave) is required, which is not always granted.
De Facto Relationship Rights and Entitlements in Australia
De facto couples in Australia enjoy many of the same legal rights as married couples, particularly in relation to property division, spousal maintenance, parenting arrangements, and superannuation splitting.
Property Settlement Rights
When a de facto relationship ends, both parties have the right to seek a property settlement under the Family Law Act 1975. The process mirrors that for married couples and involves:
- Identifying the asset pool — All assets, liabilities, superannuation, and financial resources of both parties
- Assessing contributions — Financial and non-financial contributions made during and before the relationship
- Considering future needs — Factors such as age, health, earning capacity, and care of children
- Determining a just and equitable division — The court ensures the overall outcome is fair
Property included in settlement negotiations typically encompasses:
- Real estate (including the family home)
- Bank accounts and investments
- Vehicles and personal property
- Business interests
- Superannuation entitlements
- Debts and liabilities
Spousal Maintenance
De facto partners may be entitled to spousal maintenance if they cannot adequately support themselves after separation and their former partner has the capacity to pay. Maintenance orders consider:
- The financial needs of the applicant
- The capacity of the other party to provide support
- Age and health of both parties
- Duration of the relationship
- Impact on earning capacity due to the relationship
Parenting Arrangements
Children of de facto relationships have the same legal status as children of married couples. The Family Law Act 1975 provides that:
- Both parents share parental responsibility
- The best interests of the child are the paramount consideration
- Parents are encouraged to reach agreements through mediation before court proceedings
- Child support obligations apply equally to de facto couples
Superannuation Splitting
Superannuation is treated as property under Australian family law and can be split between de facto partners as part of a property settlement. This includes:
- Accumulation funds
- Defined benefit schemes
- Self-managed superannuation funds (SMSFs)
According to the Australian Taxation Office, superannuation splitting laws enable super interests or payments to be divided by agreement or court order when a relationship breaks down.
De Facto Relationships in Western Australia: Key Differences
Western Australia operates under a separate family law system for de facto relationships. While the Family Law Act 1975 (Cth) applies to married couples in WA, de facto relationships are governed by the Family Court Act 1997 (WA).
Key Differences for WA De Facto Couples
| Aspect | Other States/Territories | Western Australia |
|---|---|---|
| Governing legislation | Family Law Act 1975 (Cth) | Family Court Act 1997 (WA) |
| Court jurisdiction | Federal Circuit and Family Court of Australia | Family Court of Western Australia |
| Superannuation splitting | Available since 2009 | Available since September 2022 |
| Definition of de facto | Section 4AA, Family Law Act | Section 13A, Interpretation Act 1984 (WA) |
Recent Changes: Superannuation Splitting in WA
The Family Law Amendment (Western Australia De Facto Superannuation Splitting and Bankruptcy) Act 2020 introduced superannuation splitting for de facto couples in Western Australia, bringing them in line with the rest of Australia. This change addresses what was previously a significant disadvantage for WA de facto couples, particularly women who often have lower superannuation balances.
Geographical Requirements
For the Family Court of Western Australia to make property orders for de facto couples:
- At least one party must be residing in Western Australia when the application is filed
- At least one-third of the relationship must have occurred in WA, OR
- Substantial contributions must have been made while residing in WA
Registering Your De Facto Relationship in Australia
While de facto relationships do not require registration to be legally recognised, many Australian states and territories offer relationship registration through their Registry of Births, Deaths, and Marriages. Registration provides formal evidence of your relationship and can simplify property claims and entitlements.
Where Can You Register a De Facto Relationship?
| State/Territory | Registry Name | Residency Requirement | Processing Time |
|---|---|---|---|
| New South Wales | Registry of Births, Deaths and Marriages | One partner must reside in NSW | 28 days |
| Victoria | Births, Deaths and Marriages Victoria | 3 months residency for one partner | 28 days minimum |
| Queensland | Queensland Registry of Births, Deaths and Marriages | 6 months residency for one partner | 10 days |
| Tasmania | Tasmania Department of Justice | Both partners must reside in TAS | 28 days |
| ACT | Access Canberra | One partner must reside in ACT | Varies |
| South Australia | Consumer and Business Services | One partner must reside in SA | Varies |
| Western Australia | Registry of Births, Deaths and Marriages | Available but limited recognition | Varies |
Benefits of Registering Your De Facto Relationship
- Simplified proof — A certificate provides clear evidence of your relationship for legal matters
- Property settlement access — Registration is one of the “gateway” criteria for court applications
- Centrelink and government benefits — Easier verification of relationship status
- Immigration purposes — Useful for partner visa applications (except WA registration)
- Inheritance rights — Clearer rights if your partner dies without a will
- Superannuation beneficiaries — Stronger entitlement to death benefits
When a De Facto Relationship Ends: Your Options
When a de facto relationship breaks down, couples have several pathways for resolving property and parenting matters. Understanding your options early can save significant time, stress, and legal costs.
Option 1: Private Agreement
Couples who can communicate effectively may reach a private agreement about property division and parenting arrangements without formal intervention. However, informal agreements are not legally binding and cannot be enforced by a court.
Option 2: Family Dispute Resolution (Mediation)
Family dispute resolution, commonly known as mediation, is a structured process where a neutral, accredited mediator helps separating couples reach agreements. At Mediations Australia, our nationally accredited mediators specialise in helping de facto couples resolve disputes efficiently and cost-effectively.
Benefits of mediation for de facto couples:
- Cost-effective — Significantly cheaper than litigation
- Faster resolution — Matters can often be resolved in weeks rather than months or years
- Control over outcomes — Parties make their own decisions rather than having a judge decide
- Confidential — Discussions remain private
- Less adversarial — Preserves relationships, especially important where children are involved
- Flexibility — Sessions can be arranged at convenient times, including online mediation
Did you know? The Federal Circuit and Family Court of Australia requires parties to make a “genuine effort” to resolve disputes before filing court applications. Attending mediation demonstrates this effort and may be required to obtain a Section 60I certificate for parenting matters.
Option 3: Binding Financial Agreement (BFA)
A Binding Financial Agreement is a legally enforceable contract that sets out how property will be divided. BFAs can be made:
- Before a de facto relationship begins
- During the relationship
- After separation
Both parties must receive independent legal advice, and each lawyer must sign a certificate confirming advice was given.
Option 4: Consent Orders
Consent orders are court orders that formalise an agreement reached between the parties. They are legally enforceable and provide certainty about property division and parenting arrangements. The Federal Circuit and Family Court must be satisfied that the proposed orders are “just and equitable” before approving them.
Option 5: Court Proceedings
If agreement cannot be reached through negotiation or mediation, either party can apply to the court for orders. Court proceedings should generally be a last resort due to:
- High legal costs (often tens of thousands of dollars)
- Lengthy timeframes (cases can take 12-24 months or longer)
- Loss of control over outcomes
- Emotional toll on all parties, including children

De Facto Relationship Property Settlement: The Process
Property settlement following the breakdown of a de facto relationship follows a structured four-step process established by the Family Law Act 1975.
Step 1: Identify and Value the Property Pool
All assets, liabilities, superannuation, and financial resources of both parties must be identified and valued. This includes:
- Assets acquired before the relationship — Properties, savings, investments
- Assets acquired during the relationship — Family home, joint accounts, vehicles
- Assets acquired after separation — May still be included depending on circumstances
- Liabilities — Mortgages, credit card debts, personal loans
- Superannuation — All superannuation interests of both parties
- Financial resources — Interests in trusts, expected inheritances
Step 2: Assess Contributions
The court assesses contributions made by each party throughout the relationship:
Financial Contributions:
- Income and earnings
- Inheritances and gifts
- Assets brought into the relationship
- Financial support from family
Non-Financial Contributions:
- Homemaking and parenting
- Renovations and property improvements
- Supporting a partner’s career development
- Caring for elderly relatives
Step 3: Consider Future Needs
Section 75(2) (or Section 90SF for de facto couples) sets out factors that may justify an adjustment to recognise future needs:
- Age and health of each party
- Income-earning capacity
- Care responsibilities for children
- Duration of the relationship
- Financial circumstances and resources
- Standard of living during the relationship
Step 4: Determine Just and Equitable Division
The court must be satisfied that the proposed division is “just and equitable” in all the circumstances. This does not necessarily mean a 50/50 split—the division depends on the specific facts of each case.
Death of a De Facto Partner: Inheritance Rights
If your de facto partner passes away, your legal rights depend on whether they left a valid will and the nature of your relationship.
Intestacy (No Will)
If your de facto partner dies without a will, you may be entitled to a share of their estate under intestacy laws. The specific entitlements vary by state and territory, but generally, a de facto partner is treated similarly to a married spouse.
Contesting a Will
If your partner’s will does not adequately provide for you, you may be able to make a claim for further provision from the estate under family provision legislation (sometimes called “testator’s family maintenance”).
Superannuation Death Benefits
De facto partners are typically recognised as dependants for superannuation death benefit purposes. However, ensuring your partner has made a valid binding death nomination in your favour provides greater certainty.
Workers’ Compensation
If your de facto partner dies from a work-related injury or illness, you may be entitled to compensation as a dependent under workers’ compensation legislation.
Protecting Your Assets: Binding Financial Agreements for De Facto Couples
A Binding Financial Agreement (BFA) allows de facto couples to specify how property and financial matters will be handled if the relationship ends. Often referred to as a “prenup” or “cohabitation agreement,” a BFA can provide certainty and protection.
Types of Binding Financial Agreements
| Type | When Made | Purpose |
|---|---|---|
| Cohabitation Agreement | Before moving in together | Protects pre-relationship assets and sets expectations |
| De Facto Relationship Agreement | During the relationship | Documents current financial arrangements and future intentions |
| Separation Agreement | After separation | Records agreed property division |
Requirements for a Valid BFA
For a Binding Financial Agreement to be enforceable:
- The agreement must be in writing and signed by both parties
- Both parties must receive independent legal advice from separate lawyers
- Each lawyer must sign a certificate confirming advice was given
- The agreement must not have been obtained by fraud, duress, or unconscionable conduct
- There must have been full financial disclosure
When Courts May Set Aside a BFA
Courts can set aside a BFA in limited circumstances, including:
- Fraud or misrepresentation
- Failure to disclose material matters
- Unconscionable conduct
- Impracticability due to changed circumstances
- Material change affecting the care of children
De Facto Relationships and Children
Children of de facto relationships have the same legal rights and protections as children of married couples under the Family Law Act 1975.
Parenting Arrangements After Separation
When de facto parents separate, they must make arrangements for:
- Who the child lives with — The child’s primary residence
- Time spent with each parent — Regular contact schedules
- Parental responsibility — Decision-making for major issues like education, health, and religion
- Communication — How parents will communicate about the child
Parenting Plans
A parenting plan is a written agreement about parenting arrangements. While not legally enforceable, parenting plans:
- Demonstrate cooperation between parents
- Provide a framework for parenting arrangements
- Can be varied as circumstances change
- Are considered by courts if disputes arise later
Mediations Australia offers dedicated parenting plan mediation services to help de facto couples create comprehensive, workable arrangements.
Parenting Orders
If parents cannot agree, either party can apply to the Federal Circuit and Family Court for parenting orders. Before applying for parenting orders (except in cases involving family violence or urgency), parties must attempt family dispute resolution and obtain a Section 60I certificate.
Child Support
De facto parents have the same child support obligations as married parents. The Child Support Agency administers child support payments based on:
- Income of both parents
- Care arrangements
- Number of children
- Ages of children
- Costs of raising children
Evidence of a De Facto Relationship
Proving the existence of a de facto relationship can be crucial for property settlement claims. Documentary evidence strengthens your position.
Types of Evidence
Financial Evidence:
- Joint bank account statements
- Shared credit cards or loans
- Joint ownership of property or vehicles
- Joint household bills (electricity, gas, internet)
- Tax returns listing your partner as a spouse
Social Evidence:
- Photos of the couple together
- Social media posts showing the relationship
- Statements from family and friends
- Joint invitations to events
- Correspondence addressing you as a couple
Living Arrangement Evidence:
- Lease agreements or property titles
- Mail addressed to both parties at the same address
- Evidence of shared household responsibilities
Relationship Evidence:
- Relationship registration certificate (if applicable)
- Joint wills naming each other
- Superannuation beneficiary nominations
- Insurance policies naming your partner
De Facto vs Marriage: Key Legal Differences
While de facto couples enjoy many of the same rights as married couples, some important differences remain.
| Aspect | Marriage | De Facto Relationship |
|---|---|---|
| Formal recognition | Marriage certificate issued | Registration available but optional |
| Time limit for property claims | 12 months after divorce | 2 years after separation |
| Divorce required to end | Yes — formal divorce order needed | No — relationship ends upon separation |
| Court jurisdiction (WA) | Family Court of WA under FLA 1975 | Family Court of WA under FCA 1997 |
| International recognition | Generally recognised worldwide | May not be recognised overseas |
| Proof requirements | Marriage certificate | May need to prove relationship existed |
Frequently Asked Questions About De Facto Relationships
How long do you have to live together to be de facto in Australia?
While two years is the typical threshold for property settlement claims under the Family Law Act 1975, a de facto relationship can exist for shorter periods if there is a child of the relationship, substantial contributions were made, or the relationship was registered.
Can you be in a de facto relationship without living together?
Yes. Following the High Court decision in Fairbairn v Radecki [2022], couples do not need to physically cohabit to be in a de facto relationship. Courts will consider all circumstances, including the commitment to a shared life, financial interdependence, and public reputation as a couple.
Do de facto partners automatically inherit if there’s no will?
Generally yes, under intestacy laws de facto partners are typically treated similarly to married spouses. However, proving the existence of the de facto relationship may be required, and specific entitlements vary by state and territory.
How is property divided when a de facto relationship ends?
Property is divided following the four-step process: identifying the property pool, assessing contributions, considering future needs, and determining a just and equitable division. The division depends on the specific circumstances of each case and is not necessarily 50/50.
Do I need a lawyer for de facto property settlement?
While not legally required, obtaining legal advice is strongly recommended. For Binding Financial Agreements, independent legal advice is mandatory for each party. Mediations Australia can help you navigate the process and refer you to experienced family lawyers when needed.
Can de facto partners claim superannuation?
Yes. Superannuation is treated as property under the Family Law Act 1975 and can be split between de facto partners as part of a property settlement. This applies in all states and territories, including Western Australia since 2022.
What happens to jointly owned property after separation?
Jointly owned property forms part of the property pool and will be dealt with as part of the overall settlement. Options include selling the property and dividing proceeds, one party buying out the other’s share, or transferring ownership to one party with offsetting arrangements.
How long does a de facto property settlement take?
Timeframes vary depending on complexity and whether parties can reach agreement. Mediation through Mediations Australia can resolve matters in weeks to a few months. Court proceedings typically take 12-24 months or longer.
