Divorce in Australia:
the formal process.

Divorce is the legal dissolution of a marriage. The marriage legally continues until the divorce takes effect, even if the parties have lived apart for years. Many people remain separated for a substantial period before applying for divorce, and they may resolve parenting and financial matters during that time. Divorce is only available to people who are legally married.

De facto separation does not involve a divorce application. De facto financial issues are dealt with under a separate framework and are not the subject of this guide.

Australia's divorce system is no-fault. The Court does not investigate adultery, abandonment, unreasonable behaviour, who initiated the separation, or moral blame for the relationship ending. The relevant question is whether the marriage has broken down irretrievably, demonstrated by the required period of separation and no reasonable likelihood of resuming married life.

This does not mean conduct is irrelevant in every other family-law context. Family violence, for example, may remain highly relevant to parenting, safety, evidence and financial issues considered in separate proceedings.

Spouses generally must have lived separately and apart for a continuous period of at least 12 months immediately before filing. The application cannot ordinarily be filed before the separation period is complete.

Separation involves more than physical distance. One or both spouses must form and communicate the intention that the marital relationship has ended, and that intention must be acted on in some way. The precise date of separation may become important, particularly for related financial time limits. For more on what separation means before the divorce process begins, see the dedicated guide.

No single fact decides the date of separation. Matters that may be relevant include:

• Communication between the spouses about the relationship ending.
• Telling family or friends.
• Changes to sleeping arrangements.
• Financial separation.
• Changes to domestic arrangements.
• Government or institutional notifications.
• Counselling or professional records.
• Correspondence.
• Subsequent conduct.

Where dates are disputed, evidence and advice may become important.

Spouses may be separated while continuing to live in the same home. Reasons commonly include housing costs, caring responsibilities, children, health, difficulty finding alternative accommodation, safety planning or practical transition arrangements.

Where the parties remained under one roof during any of the relevant period, additional affidavit evidence is generally required. Matters that may be addressed include changes to sleeping arrangements, household duties, finances, social presentation, the emotional relationship, communication and whether family or friends were told of the separation. This guide does not provide affidavit drafting instructions.

Where spouses resume cohabitation once for a period of less than three months and then separate again, the periods of separation before and after the reconciliation may potentially be added together. The reconciliation period itself is not counted toward the 12 months.

The facts must meet the statutory requirements. Repeated or longer reconciliations may affect the calculation, and advice may be useful where dates are disputed.

At a high level, at least one spouse must have the required connection with Australia at the time of filing. That may arise through Australian citizenship, regarding Australia as home and intending to live here indefinitely, or ordinarily living in Australia for the required period before filing. This guide does not provide migration or citizenship advice.

A divorce application may be made jointly by both spouses or by one spouse alone.

Joint application

Both spouses apply together. They cooperate in preparing the application; formal service on the other spouse is generally unnecessary; and neither spouse is labelled as opposing the divorce merely because the relationship has ended.

Sole application

One spouse applies and the other becomes the respondent. The application must generally be formally served, the applicant ordinarily cannot personally serve it, proof of service is required, and additional steps may be necessary if the respondent cannot be located.

A joint application does not imply agreement on parenting or property matters. It only means both parties are willing to apply together for the divorce itself.

An application may require, depending on the circumstances:

• Marriage details.
• The separation date.
• Information about any children of the marriage under 18.
• The jurisdictional connection with Australia.
• A marriage certificate.
• Evidence concerning separation under one roof, where applicable.
• Translated documents and translator material where documents are not in English.
• Information explaining name differences, where relevant.

The Court's online portal and forms change from time to time, and this guide does not reproduce them.

An Australian divorce may be available for an overseas marriage where the jurisdictional requirements are satisfied and the marriage is legally recognised. Additional requirements may include an official marriage certificate, certified translation, an affidavit or other material from the translator, and evidence linking different names. Foreign-law recognition questions can be technical and may require specific advice.

Divorce applications are generally filed electronically through the Court's online portal. At a high level, the process includes preparing the application, uploading supporting documents, paying the filing fee or applying for a reduction where eligible, filing, arranging service where required, attending a hearing where required, and downloading the final order once available. Specific filing steps and screens change over time and are not reproduced here.

A filing fee applies and changes from time to time. A reduced fee or exemption may be available in qualifying circumstances, for example where the applicant holds certain government concession cards or is experiencing financial hardship. The current fee and reduction criteria should be confirmed from the Federal Circuit and Family Court of Australia website at the time of filing.

Where one spouse applies alone, the respondent generally must be served within the required timeframe. The applicant ordinarily cannot serve the documents personally; another adult or a professional process server may perform service. Service within Australia and overseas may involve different timing requirements. Proof of service must be filed.

Where ordinary service is not possible, the Court may consider substituted service or dispensing with service. These applications require evidence and are not granted as a matter of course.

The applicant may need to demonstrate reasonable attempts to locate the respondent. Possible steps include enquiries through known addresses, family or friends, employers where appropriate, electronic communications, publicly available information and other reasonable channels.

The Court may consider substituted service or dispensing with service where appropriate. An application is not automatically granted simply because a respondent cannot be located.

Opposition is limited because divorce is no-fault. A respondent may raise matters such as the 12-month separation requirement not being met, incorrect separation dates, jurisdictional requirements not being satisfied, procedural or service defects, or the marriage already having ended or not being legally valid in the asserted way. A respondent cannot ordinarily prevent the divorce merely because they want the marriage to continue.

Whether attendance is required depends on the circumstances, including whether the application is joint or sole, whether there are children of the marriage under 18, whether the respondent opposes or seeks to attend, whether the parties were separated under one roof, any service issues, deficiencies or questions identified by the Court, and current Court procedures. Hearings are not always required, and they are not always optional. The position should be checked for the particular application.

Where there are children of the marriage under 18, the Court must be satisfied that proper arrangements have been made for their care, welfare and development. Information addressed in the application may include living arrangements, time with parents, schooling, health, financial support and any special needs.

The divorce hearing is not a parenting case. The Court may adjourn the divorce application if the information is insufficient, but it does not decide parenting disputes through the divorce process. For a fuller treatment, see parenting arrangements after separation.

Parents may agree informally, record arrangements in a parenting plan, seek consent orders, or seek parenting orders where agreement is not possible. A divorce application cannot be used to obtain parenting orders, and a parenting dispute does not ordinarily delay a divorce that otherwise meets the requirements. For a closer look at the difference between parenting plans and consent orders, see the dedicated guide.

Divorce does not, by itself, divide the home, bank accounts, investments, businesses, debts, superannuation or personal property. Property arrangements may be resolved before or after divorce, and many parties resolve property before applying for divorce so that the post-divorce time limit is not a concern. For a wider treatment, see how property settlement deals with assets, debts and the family home, and on out-of-court options see property settlement without going to court.

Once a divorce takes effect, a married party generally has 12 months to commence proceedings for property adjustment or spousal maintenance. The 12 months begins when the divorce takes effect, not on separation. Applying outside that time may require the Court's permission or another legal basis, and permission is not automatic. Parties should not assume ongoing negotiations stop time running. For more detail, see the property-settlement time limit after divorce.

Divorce does not itself create, determine or end child-support obligations. Child support is administered separately and may involve an administrative assessment, a private agreement, collection arrangements, or court orders in particular circumstances. For an overview of how child support is assessed and collected, see the cornerstone guide.

Spousal maintenance is separate from divorce. A maintenance claim depends on matters such as need, capacity to pay, statutory considerations, timing, and any existing agreements or orders. Entitlement is not automatic, and this guide does not provide a calculator. Parties may also address property and maintenance privately through financial agreements before, during or after a relationship, subject to strict statutory requirements.

A divorce ordinarily becomes final one month and one day after it is granted, unless the Court makes a special order changing that period. The hearing or grant date is not the date the divorce takes effect. The final order should be downloaded and retained securely; it is the document used to prove that the divorce is final.

A person must not remarry until the divorce is final. Marriage plans should allow sufficient time, because service or evidence issues may cause delay and a divorce will not necessarily be granted on the first listed date. The final divorce order may be required by a celebrant. Notice-of-intended-marriage timing rules apply separately and should be checked with the celebrant.

Separation and divorce may affect, but do not necessarily resolve, wills, executor appointments, gifts to a former spouse, powers of attorney, superannuation death-benefit nominations, life insurance, jointly owned assets and guardianship arrangements. The effect varies by jurisdiction and document type, and is not uniform across the country. A review with a suitably qualified professional is generally appropriate around the time of separation and again after the divorce becomes final.

A divorce does not force either spouse to change their name. A person may choose to update records such as passport, driver licence, banking, taxation, Medicare, electoral enrolment, professional registrations and employment records. The processes vary by agency and are not addressed in detail here.

People experiencing family violence may need additional safeguards regarding service, address confidentiality, attending hearings, communication, safety planning and contact details. Where direct contact with the other spouse is unsafe, it should not be assumed. If a person is in immediate danger, contact emergency services.

• Filing before the separation period is complete.
• Inconsistent or unclear separation dates.
• Insufficient evidence of separation under one roof.
• Service not completed.
• Defective proof of service.
• Missing or unclear marriage certificate.
• Translation problems.
• Incomplete information about children.
• Jurisdictional information not established.
• Name discrepancies.
• The respondent cannot be located.
• Documents filed too late.

Not every defect causes dismissal. Many issues can be addressed by amendment, further evidence or an adjournment.

• “Divorce settles the property division.” It does not.
• “Divorce determines where the children live.” It does not.
• “The other spouse must agree to the divorce.” They do not, in a sole application.
• “Adultery changes whether divorce will be granted.” It does not.
• “You must live in separate homes for 12 months.” You may be separated under one roof.
• “A joint application means all family-law issues are agreed.” It does not.
• “The divorce is final on the hearing date.” It generally becomes final one month and one day later.
• “You can remarry as soon as the Court grants the divorce.” Not until it takes effect.
• “There is no deadline for property proceedings after divorce.” A general 12-month period applies.
• “A short marriage requires mandatory counselling before divorce.” The same Part VI divorce process applies regardless of the length of the marriage.
• “Divorce automatically revokes every will, nomination and financial arrangement.” The effect varies and should be reviewed individually.
