Understanding de facto relationship rights in Australia
Most de facto relationship rights in Australia are contained in Part VIIIAB of the Family Law Act 1975 (Cth). These rights cover property settlements, spousal maintenance and parenting arrangements after separation. Western Australia uses the Family Court Act 1997 (WA) for de facto property and maintenance, but the overall approach is similar and superannuation splitting is available.
To bring a property or maintenance application you generally need to show either: (1) a relationship of at least 2 years; or (2) a child of the relationship; or (3) substantial contributions by one partner with a serious injustice if orders are not made; or (4) a registered relationship in a state or territory that offers registration.

Your de facto rights at a glance
What rights can apply
- Property settlement: division of assets and debts in a just and equitable way, including superannuation splitting.
- Spousal maintenance: support where one person cannot adequately support themselves and the other can pay.
- Parenting arrangements: orders about who a child lives with, spends time with and decision-making responsibility.
- Child support: usually assessed by Services Australia, separate from property orders.
- Financial agreements: binding agreements before, during or after the relationship.
- Family violence protections: safety orders and court safeguards if there is risk or abuse.
Key differences from marriage
De facto partners generally have similar rights to married couples for property, maintenance and parenting. The main differences are the threshold to prove a de facto relationship and the time limit to start a case. Evidence of the relationship and separation date often matters more in de facto matters.
Property and money after a de facto separation
Courts use a structured approach to decide a fair outcome. While each case is unique, the common steps are:
- Identify the property pool: assets, liabilities and superannuation of both partners (net position) at the time of settlement.
- Assess contributions: direct and indirect, financial and non-financial (income, inheritances, care of children, homemaking, renovations, gifts).
- Consider future needs factors: age, health, earning capacity, care of children and other circumstances.
- Ensure the result is just and equitable: the outcome must be fair in all the circumstances.
Financial agreements (de facto “prenups”)
Binding financial agreements can be made before, during or after a de facto relationship. Each person must receive independent legal advice for the agreement to be enforceable. These agreements can reduce uncertainty and cost if you separate later.
Parenting and children
Parenting matters are determined by what is in the child’s best interests, regardless of whether the parents were married or de facto. The court can make orders about living arrangements, time with each parent, and decision-making. Family dispute resolution (mediation) is usually required before starting a court case, unless an exemption applies (for example, urgency or family violence).
- Focus on the child’s safety, needs and meaningful relationships.
- Parenting plans can be made informally or converted to consent orders to make them enforceable.
- Child support is assessed separately by Services Australia.
Proving a de facto relationship
Courts look at all the circumstances to decide if a de facto relationship existed (Family Law Act s 4AA). Useful indicators include:
- Length of the relationship and periods of living together
- Whether there was a sexual relationship
- Financial interdependence: joint accounts, bills, loans, tax returns
- Ownership and use of property
- Mutual commitment to a shared life
- Care and support of children
- Public aspects: how you presented the relationship to others
- Whether the relationship was registered (where available)
Evidence to collect: leases, bank and super statements, bills, photos, travel records, messages, statutory declarations from friends/family, and documents that show the separation date.
States, territories and WA differences
Most of Australia
NSW, VIC, QLD, SA, TAS, ACT and NT use the Family Law Act 1975 (Cth). Property, maintenance and parenting apply similarly for married and de facto couples.
Some jurisdictions allow relationship registration at the Registry of Births, Deaths and Marriages (e.g. NSW, VIC, QLD, ACT, TAS and SA). Registration can help establish the relationship and eligibility for orders.
Western Australia
De facto property and maintenance are dealt with in the Family Court of Western Australia under the Family Court Act 1997 (WA). Superannuation splitting for de facto couples is available. Time limits and key factors broadly align with the federal approach, but the legislation and court pathway differ.
Time limits that matter
- Property and spousal maintenance: generally start your case within 2 years of separation. After this, you need the court’s permission (leave), which is only granted in limited hardship situations.
- Parenting: no strict limitation period, but act promptly to avoid risk to the child or evidence issues.
- Urgency and safety: seek urgent advice if there is family violence, asset disposal risk or relocation concerns.
Options to resolve your de facto issue
| Option | What usually happens |
|---|---|
| DIY agreement + consent orders | You agree on terms, then file consent orders with the court to make the deal enforceable. Low cost if terms are clear. |
| Family dispute resolution (mediation) | An independent mediator helps you reach a property or parenting agreement. Often faster and cheaper than court. |
| Lawyer‑led negotiation | Lawyers identify the pool, exchange disclosure and negotiate a settlement. Can finalise by consent orders or a financial agreement. |
| Arbitration (property) | A private arbitrator decides property issues. Faster than court in many cases. Parenting cannot be arbitrated. |
| Court proceedings | Used where agreement is not possible, there is risk, or complexity requires orders. The court manages disclosure, interim issues and a final hearing if needed. |
Typical costs and how to save
Legal costs depend on complexity, cooperation and whether court is required. Indicative ranges:
- Initial consult: often free or low‑cost with many family lawyers.
- Consent orders (fixed fee): approximately $1,500–$4,000 depending on documents and complexity.
- Mediation: about $1,500–$3,500 per person; some services offer lower fees or legal aid funding if eligible.
- Negotiated settlements: vary widely based on disclosure and issues.
- Court litigation: frequently $15,000–$60,000+ for property or parenting; complex matters can exceed this.
Ways to reduce cost
- Organise disclosure early: asset/liability list, super, bank statements and key relationship documents.
- Set clear goals and your best alternative if no agreement.
- Attempt mediation before filing, where safe to do so.

De facto rights FAQ
When do de facto relationship rights apply?
Generally if you lived together on a genuine domestic basis and meet one of the eligibility thresholds: 2 years, a child, substantial contributions or a registered relationship.
Do de facto matters always go to court?
No. Many are resolved through disclosure, negotiation, mediation or arbitration (for property). Agreements can be finalised with consent orders or a binding financial agreement.
How is superannuation treated?
Super is part of the property pool and can be split by court order or a financial agreement. In WA, super splitting is available for de facto couples through the Family Court of WA.
What strengthens my case early?
A clear asset/debt list, super statements, evidence of contributions, proof of relationship and separation date, and defined goals for settlement or parenting.
Can I get de facto spousal maintenance?
