In Australia, separation and divorce are two distinct legal processes: separation is the act of ending a relationship and living apart, while divorce is the formal legal dissolution of a marriage granted by the Federal Circuit and Family Court of Australia. You can be legally separated without ever applying for a divorce, but you must be separated for at least 12 months before a divorce application will be considered.
What Is Separation Under Australian Law?
Separation occurs the moment one or both partners decide the relationship is over and communicate that decision — there is no court order or paperwork required to be "separated" in Australia. This applies equally to married couples and de facto partners.
The date of separation matters enormously because it starts several legal clocks ticking. For married couples, you must wait 12 months from the date of separation before filing for divorce. For de facto couples, most property settlement claims must be commenced within two years of separation, while married couples have 12 months from the date a divorce order becomes final.
It is even possible to separate while still living under the same roof — a concept known as "separation under one roof." This is increasingly common given Australia's high cost of living; according to the Australian Bureau of Statistics (ABS), the median dwelling price in Sydney exceeded $1.4 million in 2025, making it financially impossible for many separating couples to immediately live apart. If you claim separation under one roof, the court will examine evidence such as sleeping arrangements, separate finances, and whether you still socialise as a couple.
Because there is no formal separation register in Australia, it is wise to document the date clearly — send an email, write a statutory declaration, or note it in communications with a solicitor. If you and your former partner disagree on the separation date, this can become a contested issue in later property or parenting proceedings.
What Is Divorce Under Australian Law?
Divorce is a formal court order that legally ends a marriage. Australia operates a no-fault divorce system under the *Family Law Act 1975*, which means neither party needs to prove wrongdoing — the only ground is irretrievable breakdown of the marriage, evidenced by 12 months of separation.
An application can be made sole (by one party) or joint (by both parties together). Joint applications are generally smoother and less adversarial. Once granted, a divorce order becomes final one month and one day after it is made by the Federal Circuit and Family Court of Australia.
Crucially, divorce does *not* automatically resolve property settlements, spousal maintenance, or parenting arrangements. These are entirely separate legal proceedings. Many Australians are surprised to discover they can be divorced yet still have unresolved financial ties to their former spouse — sometimes for years.
According to the ABS, Australia recorded approximately 49,200 divorces in 2023, the most recent full year of data, representing a crude divorce rate of 1.8 per 1,000 people. Working with best family lawyers in Sydney or in your local area can make the filing process significantly less stressful.
Key Legal Differences at a Glance
The table below summarises the three most common legal statuses and their practical implications for Australians in 2026.
| Legal Status | Who It Applies To | Formal Court Process Required? | Typical Cost (AUD, 2026) | Time Considerations | |---|---|---|---|---| | Separation | Married & de facto couples | No | $0–$500 (legal advice optional) | Starts the 12-month clock for divorce; 2-year property window for de facto | | Divorce | Married couples only | Yes — Federal Circuit and Family Court | $1,060 (court filing fee) + $1,500–$5,000+ (legal fees) | Application lodged after 12 months separation; order final after ~31 days | | Annulment (Nullity) | Married couples in specific circumstances | Yes — rare and complex | $3,000–$10,000+ (legal fees) | No time minimum — but grounds are strict (e.g., bigamy, duress) |*Court filing fees current as of January 2026; legal fee estimates based on average solicitor rates.

Property Settlements: Different Rules for Married vs De Facto Couples
One of the most consequential differences between separation and divorce relates to how property is divided — and the deadlines involved.
For married couples, the 12-month post-divorce deadline to commence property settlement proceedings is strict. Miss it, and you will generally need the court's permission (known as leave) to proceed, which is not guaranteed. For de facto couples, the two-year post-separation deadline applies, and de facto relationships are now recognised nationally under the *Family Law Act 1975* following legislative harmonisation.
The Family Court considers four main steps when dividing assets: identifying and valuing the asset pool, assessing contributions (financial and non-financial), adjusting for future needs, and ensuring the outcome is just and equitable. The ATO has become increasingly involved in family law matters — superannuation splitting orders, for instance, allow super to be flagged or split between parties, and the ATO administers the superannuation information-sharing scheme used in these cases.
Superannuation is treated as property in Australia, though it cannot simply be paid out as cash upon divorce. Instead, a superannuation splitting order must be drafted carefully in accordance with APRA-regulated fund requirements. APRA-regulated funds (which cover most industry and retail super funds) have specific procedures for implementing these orders that your solicitor must follow precisely.
Parenting Arrangements After Separation
Separation immediately raises questions about children — and the law is clear that parenting arrangements are entirely separate from divorce proceedings. The guiding principle under the *Family Law Act 1975* is the best interests of the child, not the rights or preferences of either parent.
Parents can formalise arrangements via a parenting plan (a written agreement, not legally binding) or consent orders (approved by the court and legally enforceable). If agreement cannot be reached, either party may apply to the court for parenting orders. Before doing so, most parents are required to attempt family dispute resolution (FDR) with an accredited mediator — a requirement waived only in cases involving family violence or child abuse.
Equal shared parental responsibility remains a presumption in law unless there are safety concerns, though it does not automatically mean equal time. The distinction matters and is frequently misunderstood. Legal advice at this stage can be invaluable; learn more about how we evaluate providers on our methodology page.
When Do You Actually Need a Family Lawyer?
Not every separating Australian needs a solicitor for every step, but there are situations where professional advice is essential:
- Contested property settlements, particularly those involving businesses, trusts, or self-managed super funds (SMSFs) - Parenting disputes where family violence, substance abuse, or relocation is involved - International elements, such as a spouse living overseas or assets held abroad - Short marriages or de facto relationships where contribution claims are complex - Domestic violence situations, where independent legal advice protects your safety and rights
For uncontested divorces with straightforward circumstances, some Australians use online legal services or court self-help resources. However, getting at least one consultation with a family lawyer before signing any agreement — including a binding financial agreement (BFA) — is strongly recommended.

FAQ
Q: Can I date other people after separation but before my divorce is finalised? A: Yes, legally. Once separated, you are free to enter new relationships. However, new relationships formed close to the separation date can occasionally be relevant to property proceedings if they involve significant financial entanglement. Q: Does separation affect my will or superannuation beneficiary nominations? A: In most Australian states, separation alone does not automatically revoke a will or change a superannuation beneficiary nomination — divorce typically does. You should update both documents as soon as possible after separating to reflect your current intentions. Q: How long does a divorce application take to process in 2026? A: Once your application is lodged, the Federal Circuit and Family Court typically lists a hearing date within approximately 8–12 weeks, though this varies by registry. If granted, the divorce order becomes final one month and one day later. Q: What if my spouse refuses to sign the divorce application? A: A sole application does not require your spouse's agreement or signature. Your spouse must be formally served with the application documents, but they cannot legally prevent a divorce from being granted once the 12-month separation period is established.---
