Family Law in Australia: A Complete Guide for Separating Couples

Separation and Divorce

Separation is a question of fact, not a question of form. Under the Family Law Act, a couple is separated when at least one party has formed and communicated an intention to end the relationship and the nature of the relationship has changed accordingly. There is no requirement to file anything; no requirement that either party leave the home; no requirement that the other party agree. The date of separation is, however, decisive: it starts the clock for divorce, it commonly fixes the date for property valuation, and it begins the limitation periods for de facto property and spousal-maintenance claims. Where the date is contested, contemporaneous evidence — texts, emails, statutory declarations from family or friends — is decisive.

Couples who cannot or do not wish to live apart can be 'separated under one roof'. Section 49(2) of the Family Law Act expressly contemplates it, and the Court accepts properly evidenced separation in shared accommodation provided the marital relationship has clearly ended. Evidence typically includes separate bedrooms, separated meals, separated finances, separated social activities and a clear communication of intention. For a divorce application based on separation under one roof, the Court requires affidavit evidence from both parties and a corroborating affidavit from a friend or relative. The mechanics are set out in our companion guide on divorce after twelve months separation.

Divorce is the formal termination of the marriage. It is available after twelve months and one day of separation, on a no-fault basis, on the single ground of irretrievable breakdown. The application is procedural rather than substantive — the Court is not interested in why the marriage failed, only that it has. Joint or sole applications are equally available. Marriages of less than two years require evidence of counselling or an explanation of why counselling is impracticable. Divorce does not deal with property or parenting and it does not extend the limitation period for property settlement; on the contrary, the date the divorce order becomes final starts a strict twelve-month window for property and spousal-maintenance applications. The procedural detail is in our companion guide on how to apply for divorce in Australia.

De Facto Relationships

Since 2009 (Victoria 2010) de facto couples, including same-sex couples, have substantially the same property and spousal-maintenance rights as married couples under Part VIIIAB of the Family Law Act. The threshold question is whether a de facto relationship exists. Section 4AA asks whether the parties were 'living together on a genuine domestic basis' having regard to the duration of the relationship, the nature and extent of common residence, whether a sexual relationship exists, the degree of financial dependence and interdependence, the ownership, use and acquisition of property, the degree of mutual commitment to a shared life, the care and support of children and the reputation and public aspects of the relationship.

Jurisdiction under Part VIIIAB requires at least one of four gateways: cohabitation for at least two years; a child of the relationship; substantial contributions making non-recognition seriously unjust; or registration of the relationship under the Relationships Act 2008 (Vic) or equivalent state legislation. Where jurisdiction is established, the Court applies the same four-step property analysis used in married-couple cases (see below). The most important practical difference is the limitation period: de facto applications must be brought within two years of separation, not twelve months from divorce, and out-of-time applications require leave on stringent grounds. See our companion guide on de facto property claims.

Parenting Arrangements and Parenting Orders

Parenting decisions after separation are governed by Part VII of the Family Law Act. The paramount consideration is the best interests of the child, assessed by reference to the primary considerations (the benefit of a meaningful relationship with both parents and the need to protect the child from harm) and the additional considerations in section 60CC (the child's views, the child's relationships, the practical effect of separation from a parent, the capacity of each parent to provide for the child's needs and the family-violence history). The former presumption of equal shared parental responsibility has been significantly modified by the 2024 amendments; decision-making is now case-specific rather than presumption-driven, with safety the dominant consideration.

Most separated parents reach parenting arrangements without court orders. A 'parenting plan' is a written, signed agreement — not enforceable as an order, but persuasive evidence of intention and a useful framework. Consent parenting orders are a parenting plan lodged with the Court and approved by a Registrar; they have the force of court orders and can be enforced. Contested parenting orders are made after litigation, usually following Family Dispute Resolution. The categories of parenting orders are: live with orders, spend time orders, communicate with orders, parental responsibility orders, specific issue orders (schooling, religion, medical treatment) and overseas-travel orders.

Family Dispute Resolution (FDR) is, with limited exceptions, a precondition to filing parenting proceedings. A registered FDR practitioner attempts to assist the parents to reach agreement; where agreement is not reached (or where a party refuses to attend or does not attend in good faith), the practitioner issues a section 60I certificate that is required to file in Court. Exceptions to FDR include urgency, family violence or child abuse, undue delay and lack of capacity to participate. Our companion guide on parenting arrangements after separation covers the practical decisions about residence, time, and communication; the related guide on parental financial responsibility covers the financial obligations that operate alongside parenting time.

Child Support

Child support is the financial contribution made by a parent for the support of a child. It is administered by Services Australia (the Child Support Agency) under the Child Support (Assessment) Act 1989 (Cth) and is separate from parenting orders and from property settlement. The formula assessment uses both parents' adjusted taxable incomes, the percentage of nights of care that each parent provides, and the statutory costs-of-children table. The assessment is updated annually with tax data; either parent can apply for a 'change of assessment' on specified grounds where the formula produces an unfair result.

Parents who prefer to set their own arrangements may enter a limited child support agreement (which can be reviewed and varied) or a binding child support agreement (which requires independent legal advice on both sides and is enforceable as a contract). Binding agreements should be used with caution: they bind both parents even where circumstances change dramatically. The detailed mechanics, including the formula percentages, the change of assessment process and the choice between limited and binding agreements, are in our companion guide on child support assessments and agreements.

Property Settlements

Property settlement is the division of the parties' assets, liabilities and superannuation after separation. For married couples it is governed by section 79 of the Family Law Act; for de facto couples by section 90SM. The Court applies a four-step process, which is also the framework used in every properly conducted negotiation, mediation or consent-order exercise.

Step one — identify and value the asset pool. All property, in joint and sole names, in either party's name and in any controlled entity, is brought into the pool. This includes the family home, investment properties, businesses, professional practices, shares, cryptocurrency, superannuation, vehicles, jewellery and redundancy entitlements; liabilities (mortgages, personal loans, tax debts, credit cards) are deducted. The pool is generally valued as at the date of trial or settlement, not the date of separation; significant post-separation acquisitions and disposals are tracked separately and adjusted in step two. Hidden, transferred or dissipated assets can be added back. Where a former spouse becomes bankrupt mid-process, the trustee in bankruptcy steps into the proceedings — see our companion guide on former spouse bankruptcy and property settlement. Digital assets present specific identification challenges — see our guide on cryptocurrency and divorce.

Step two — assess contributions. The Court weighs financial contributions (income earned, assets brought into the relationship, gifts and inheritances received during the relationship, redundancy payouts), non-financial contributions (renovation, home maintenance, business support) and contributions in the capacity of homemaker and parent. Initial contributions are commonly given less weight in long marriages than in short ones; late-stage contributions (post-separation work, post-separation mortgage payments) are tracked separately. The exercise is impressionistic rather than mathematical — the Court is producing a percentage assessment rather than adding up dollar amounts.

Step three — assess future needs. Under section 75(2) (married) or section 90SF (de facto), the Court considers the age, health, income and earning capacity of each party, the care and support of children, standard of living, the financial circumstances of any new relationship and a basket of other factors. The future-needs adjustment commonly shifts the contributions outcome by five to fifteen percentage points in favour of the lower-earning party (often the primary carer) but larger adjustments are not unusual where disparities are pronounced.

Step four — just and equitable. The Court stands back from the arithmetic and asks whether the proposed division produces a just and equitable outcome in all the circumstances. The step is not a formality: in Stanford v Stanford (2012) 247 CLR 108 the High Court held that the threshold question is whether it is just and equitable to make any order altering existing property interests at all. In practice the step almost always confirms the arithmetic, but its existence is a reminder that family-law property settlements are exercises of discretion, not formulae.

The myth of automatic 50/50 division is one of the most damaging misconceptions in family law. Equal division is common in long marriages with broadly equal contributions and similar future needs, but it is not the default and it is not the most common outcome. The reasons why equality is not assumed are set out in detail in our companion guide on why property is rarely split 50/50, and the full mechanics of the four-step process are in our guide on the four-step property settlement process in Australia. Business and professional interests present specific valuation and structural issues — see our companion guide on business interests in divorce property settlements. For an end-to-end walkthrough — asset pool, contributions, future needs, superannuation, businesses, trusts, real estate, consent orders and time limits — see our complete guide to property settlement after separation.

Superannuation Splitting

Superannuation is property for family-law purposes and can be split between the parties under Part VIIIB of the Family Law Act. The split is implemented by an order or financial agreement served on the trustee of the superannuation fund; the trustee is then bound to give effect to the split when a condition of release occurs. The receiving spouse's split is generally rolled into their own superannuation account; it is not paid out as cash unless the receiving spouse has independently satisfied a condition of release.

Three categories of fund present specific issues. Accumulation funds (industry and retail funds) are the most straightforward: the member balance is the value, a percentage or dollar split is straightforward, and the trustee process is well-established. Defined-benefit funds require actuarial valuation under the family-law regulations and have rigid rules on the form and timing of any split. Self-managed superannuation funds (SMSFs) require particular care: the same individuals are commonly trustee, member, custodian and counterparty; the asset mix may include illiquid property and limited recourse borrowing; and the trustee changes and rollover mechanics need to be implemented in lock-step with the split order. See our companion guide on superannuation splitting in divorce.

Spousal maintenance — distinct from property division — is the periodic or lump-sum financial support paid by one spouse to the other where the receiving spouse cannot adequately support themselves and the paying spouse has capacity to pay. The application is means-tested on both sides. Most maintenance orders are short-term, supporting the receiving spouse through a period of retraining or re-entry to the workforce; long-term maintenance is rare but is awarded where age, health or care responsibilities make self-support impossible. The detail is in our companion guide on spousal maintenance in Australia.

Binding Financial Agreements

A binding financial agreement (BFA) is a private contract under Part VIIIA (married) or Part VIIIAB (de facto) of the Family Law Act recording how the parties have agreed to divide their property in the event of (or after) separation. BFAs can be entered before a relationship (the colloquial 'pre-nup'), during a relationship, or after separation. Where validly executed they oust the Court's section 79 / section 90SM jurisdiction over property and avoid the need for a court order or settlement filed as consent orders.

The procedural requirements are strict. Each party must obtain independent legal advice from an Australian legal practitioner before signing. The lawyer must provide a signed statement that the advice covered the effect of the agreement on the party's rights and the advantages and disadvantages of entering it. The agreement itself must satisfy the statutory formalities. The grounds on which a BFA can be set aside include non-disclosure, fraud, duress, unconscionable conduct, material change in circumstances relating to the care of a child, and impracticability. Strict drafting and documentation discipline is the only protection against later challenge. See our companion guide on binding financial agreements in Australia.

Family Violence

Family violence is both a free-standing safety issue and a substantive consideration in family-law property and parenting cases. In Victoria the primary protective mechanism is a family violence intervention order under the Family Violence Protection Act 2008 (Vic), made by the Magistrates' Court on application by the affected family member or the police. The application can include exclusion conditions (excluding the respondent from the family home), no-contact conditions, conditions restricting communication and conditions for the protection of children. Police can issue a Family Violence Safety Notice in urgent cases as an interim measure before a Magistrate is available.

In family-law proceedings, family violence engages multiple considerations: it is a primary consideration for the protection of children under section 60CC; it is an additional factor in property settlement (significant family violence can constitute a contribution-stream adjustment under the principles in Kennon v Kennon(1997) 22 Fam LR 1); and it dispenses with the FDR precondition for parenting applications. The intersection with intervention orders, parenting orders and property proceedings is fact-specific and benefits from coordinated advice. See our companion guides on family violence intervention orders in Victoria and on personal safety intervention orders, and our practical guides on changing locks after separation and caveats over property after separation.

Consent Orders and Litigation

Most family-law matters resolve by agreement, either recorded informally (parenting plans), formally by way of a binding financial agreement, or formally by way of consent orders. Consent orders are a written agreement between the parties presented to the Federal Circuit and Family Court for sealing as orders of the Court. A Registrar reviews the orders for jurisdiction, propriety and (in property matters) for whether the proposed outcome is just and equitable. Consent orders are particularly common for parenting and property settlement after separation; they carry the certainty and enforcement options of a court order with the procedural simplicity of an uncontested filing. See our companion guide on consent orders in family law in Australia.

Where agreement cannot be reached, contested litigation follows. Property proceedings begin with an Initiating Application and supporting financial statement and affidavit; parenting proceedings with an Initiating Application, a Notice of Risk and a section 60I certificate (or evidence of an exception). The litigation pathway involves directions hearings, interim hearings (commonly for interim parenting, interim spousal maintenance or interim property orders), a compulsory conciliation conference (property) or Child Dispute Conference (parenting), a Family Report (in most parenting cases), and ultimately a final hearing. The average time from filing to final hearing in a defended matter remains twelve to twenty-four months; complex property matters often run longer. Costs orders are the exception rather than the rule in family law; each party ordinarily pays their own costs.

Time Limits in Family Law

Two limitation periods dominate family-law property practice. For married couples, an application for property settlement or spousal maintenance must be filed within twelve months of the date the divorce order takes effect. For de facto couples, the period is two years from the date of separation. Out-of-time applications require the leave of the Court and are granted only where the applicant would suffer hardship if leave were refused and there is a reasonable case on the merits — a substantial hurdle. Parenting applications are not subject to a limitation period, but the longer the delay, the more deeply embedded the current arrangements become and the more difficult any substantial change is to obtain. See our companion guide on time limits for property settlement in Australia.

Beyond limitation periods, family law is laced with procedural deadlines: time for filing evidence in response, time for serving subpoenas, time for completing financial disclosure, time for serving expert reports. Missing a substantive limitation period is a potentially fatal procedural mistake; missing an evidentiary or directions deadline is a routine but often consequential one. Early engagement and active case management is the only effective protection.

Practical Steps After Separation

The first thirty days after separation set the tone for everything that follows. Practical priorities for any separating party include:

• Personal safety. Where family violence is a concern, secure the residence (or relocate), consider an intervention order, and notify trusted support people of the position. Safety planning is the precondition to every other step.
• Children. Agree (or, if necessary, court-order) interim parenting arrangements quickly. A consistent week-on / week-off or schedule-of-nights arrangement is generally better than an ad hoc arrangement that becomes a flashpoint each week.
• Banking. Cancel joint cards where appropriate; open an account in your sole name; ensure salary is paid into an account the other party cannot access; agree (in writing) how the mortgage, rent and joint outgoings will be paid in the interim.
• Housing. Decide who is staying in the family home (or whether both will remain temporarily); if one party is leaving, document the date of departure, the inventory taken and the access arrangements going forward.
• Documents. Collect copies (not originals) of all financial records, tax returns, superannuation statements, business records, loan agreements, leases and the marriage certificate. Take dated photographs of household contents. Disclosure obligations in family law are extensive; early collection prevents disputes later.
• Estate planning. Update your will and powers of attorney immediately. Separation does not revoke gifts to a spouse under a will, and the estranged spouse remains entitled until either the will is updated or, for married couples, a divorce order takes effect. Update superannuation binding nominations and life-insurance beneficiary designations — these are often missed for years.
• Digital security. Change passwords on email, banking, social media and shared cloud accounts. Consider two-factor authentication. Family violence increasingly has a digital dimension; basic digital hygiene is part of post-separation housekeeping for everyone, not only those experiencing violence.
• Communication. Establish a single, written channel of communication with the former partner — ideally email, ideally limited to parenting and finance, ideally polite and brief. Verbal arrangements become disputed; written arrangements rarely do.

When to Obtain Legal Advice

The most valuable family-law advice is the advice obtained earliest. A single conference with a family lawyer in the days after separation typically covers the shape of the asset pool, the realistic range of outcomes, the immediate practical priorities, the time limits in play, and the choice between consent orders, BFA and litigation. The cost of that conference is invariably a small fraction of the cost of remedying a decision made without it.

Specific triggers for advice — none of which are optional — include: any allegation or risk of family violence; any intention to relocate with children; any intention to enter a new significant relationship; any substantial financial transaction (sale of a property, withdrawal of superannuation, refinance of the mortgage); any approach from the former partner's lawyer; any communication suggesting consent orders or a BFA; any proposed agreement reached at mediation; any tax event (including the disposal of an asset for property- settlement purposes); and any indication that the limitation period is approaching.
