On what grounds can I apply for divorce?

The only ground for divorce is the irretrievable breakdown of the marriage. A marriage is taken to have broken down irretrievably when both parties to the marriage have not been living as a married couple for at least 12 months and there is no chance of getting back together again. It does not matter who was at fault or whether both parties want a divorce.

From when does the 12 month period begin to run?

The 12 month period begins the day one or both parties leave the marriage.

Do I need to tell the other party that I am leaving the marriage?

You do not necessarily need to tell the other party, but you must make sure that you are leaving the marriage by your actions and at least in that way, you are clearly communicating it to them. Your actions might involve moving out of the same bedroom or accommodation or, if you are already living in separate accommodation, ceasing regular communication and commencing another relationship.

This is particularly important where you intend to separate under one roof (see Separation under one roof). In this case, although it is not necessary, it may be a good idea for you to tell the other that you are leaving the marriage, so there is no confusion and the other party does not hold out hope of you getting back together.

What if we tried to get back together, but then separated again?

After you separate you can try to get back together once (for up to 3 months), without having to start the whole 12 month separation period again. For example, if you separate for 3 months then get back together for 2 months, you only have to separate for a further 9 months before you can be considered to have been separated for at least 12 months [Family Law Act 1975 (Cth) s 50].

Isolated acts of sexual intercourse do not break the separation period [Feltus (1977) FLC 90-212].

Are there any other requirements?

Brief marriages

Until 10 June 2025, people married less than 2 years could not apply for divorce until they had either:

This requirement no longer applies. From 10 June 2025, those seeking a divorce need only show a separation period of at least 12 months, regardless of the length of their marriage.

Children of the marriage

If there are children of the marriage, the Court must be satisfied that proper arrangements have been made for the care, welfare and development of the children before granting divorce [Family Law Act 1975 (Cth) s 55A]. Children of the marriage includes any children under the age of 18 years who were living with the parties at the time of the separation.

Details about the children must be provided to the Court, including:

The Court has been reluctant to find that proper arrangements have been made where one party is not meeting their obligation to provide financial support for the children [see Opperman and Opperman (1978) 33 FLR 248].

The Registrar may ask further questions about these arrangements at the divorce hearing and, if completely satisfied, will make a declaration that, in all the circumstances, proper arrangements for the children's care, welfare and development have been made. In special circumstances, such as where the other party or the children cannot be found, these details are not needed for the divorce.

Although the Registrar has to approve the arrangements, they do not become court orders and are not enforceable as court orders. Separate applications must be made for parenting and child support orders.

What if we had to live together after we separated?

The law understands that sometimes following a separation, you and the other party may still have to share the same accommodation and one party may still perform some household services for the other, such as washing or ironing, for example, where it is necessary for the running of the home and the convenience of others who live there [Family Law Act 1975 (Cth) s 49(2)]. This is called separation under one roof.

As long as you can prove that one or both of you left the marriage and you began living independently of each other, the 12 month separation period can start to run and will not stop merely because you continue or resume sharing the same accommodation.

As each marriage is different, the facts tending to prove a separation under one roof may vary from case to case. Usually it is necessary to provide evidence (in an affidavit) to prove that you do not share any of the usual activities of marriage, such as:

It will be easier to prove separation under one roof if:

If you were to intend to continue living under one roof indefinitely, the Court might think there is a chance of you getting back together.

Is there anything we should do?

Yes. If you intend to rely on separation under one roof for the purposes of divorce, you should make sure that others know about it from the beginning of your separation, as the Court usually requires evidence (in an affidavit) from a neighbour, friend or relative (corroborative evidence) that there was a separation [see Pavey and Pavey (1976) 25 FLR 450].

To which court should applications be made?

All divorce applications should be made to Division 2 of the Federal Circuit and Family Court [see Family Law Practice Direction – Divorce proceedings (issued by the Federal Circuit and Family Court)].

Who can apply for divorce?

Before the Court can hear a divorce application there must be proof that either you or the other party have some link with Australia [Family Law Act 1975 (Cth) s 39(3)]. At the date of application, one of you must be:

Do we have to apply together?

No. Either party to a marriage can apply for divorce. It does not matter whether both parties want a divorce.

If both parties do want a divorce, it is possible to apply together. The main advantage of applying together is that there is then no need for one party to serve the divorce application on the other party.

Do I need a lawyer to apply for divorce?

No. You do not usually need a lawyer representing you to apply for divorce. For most people divorce is simple and they can apply for it themselves. See How do I apply for a divorce? for more information.

Divorce applications are now lodged electronically. Instructions on how to register to lodge electronically are available at the Federal Circuit and Family Court's webpage How do I register for the Commonwealth Courts Portal?

The Federal Circuit and Family Court webpage How do I apply for a divorce? also explains what to do if you are unable to electronically file your application.

If you will have difficulty applying for divorce yourself (such as if English is not your first language) or your application is complicated, you may be eligible for a grant of legal aid to pay for a lawyer to represent you.

If you need advice and help to fill in the divorce application or service forms or legal aid application form, call the Legal Helpline on 1300 366 424 during business hours.

What else will I need?

You will need to provide a copy of your marriage certificate to the Court, unless the Court already has it through other proceedings. If you are unable to do so, you must provide an affidavit with your application setting out the reasons why or give an undertaking to the Court, satisfactory to the Court, that you will provide it within a certain time.

If you were married in South Australia, you can obtain a copy of your marriage certificate through the Births, Deaths and Marriages Registration Office which is part of Consumer and Business Services.

If you were married interstate or overseas, you will need to apply to the relevant authority in that state or country.

If your marriage certificate is not in the English language, you will also need to arrange for its translation by an accredited translator. The translation and an affidavit by the translator will need to be provided to the Court with your marriage certificate.

The translator must complete the Affidavit: Translation of Marriage Certificate and sign it before a Justice of the Peace or a lawyer.

Translation services are listed in the Yellow Pages.

How much does it cost?

Current family law fees are best checked on the Federal Circuit and Family Court website. The filing fee for a divorce application is $1,100 (as at 1 July 2024). If you hold a concession card or you cannot afford to pay the fee without financial hardship, you can apply for the fee to be reduced to $365 (as at 1 July 2024).

To apply for a fee reduction you need to fill in either an:

I have applied for divorce so that I can re-marry. Is it safe to set a date for my wedding?

You cannot remarry until your divorce is final and has taken effect [Family Law Act 1975 (Cth) s 59]. Therefore, it is best not to set dates for your wedding until then.

In most cases, a divorce order becomes final one month and one day after it is made. However, you do not know exactly when your application will be heard and whether the divorce order will be made at the first hearing or at a further hearing. A further hearing may be required, for example, if you are applying on your own and you have been unable to successfully serve the other party (see Serving a divorce application) or if the other party opposes the divorce order.

There may also be a delay with the order taking effect if the other party appeals it (see The making of a divorce order).

Before remarrying in Australia, the parties must also lodge a Notice of Intended Marriage, together with certificates of divorce (if the parties were previously married) with the celebrant at least one month and one day before the marriage.

Do I need to give the other party a copy of my application?

Unless you make the application together, you must make sure the other party receives a stamped copy of your application and the brochure called Marriage, Families and Separation at least 28 days before the hearing date (or 42 days if the other party is overseas) [Federal Circuit and Family Court of Australia (Family Law) Rules 2021 (Cth) r 2.28]. This is called service.

An explanation of what you need to do to satisfy the Court can be found on the Federal Circuit and Family Court website.

The Court will only be satisfied that you have served the other party if you file either an:

If you are confident that the other party will sign an Acknowledgment of Service (Divorce) and return it to you, you can post the documents with the Acknowledgment to the other party.

Once the other party has returned the Acknowledgment to you, you will need to complete an Affidavit of Service by Post (Divorce), sign it before a Justice of the Peace or lawyer and file it, together with the Acknowledgment.

If you are not confident the other party will sign an Acknowledgment and return it to you, you should arrange for a friend or relative over the age of 18 years, or a professional process server (listed in the Yellow Pages) to personally hand the documents to the other party.

Whoever serves the documents must ask the other party to sign the Acknowledgment and if they do so, take the Acknowledgment and an Affidavit of Service by Hand (Divorce) to sign in front of a Justice of the Peace or lawyer.

If you recognise the other party's signature on the Acknowledgment, you can also take the an Affidavit Proving Signature (Divorce) and a copy of the Acknowledgment to sign in front of a Justice of the Peace or lawyer.

All of the service documents must be filed in Court. See Federal Circuit and Family Court of Australia (Family Law) Rules 2021 (Cth) rr 2.45-2.46.

What if the other party is overseas?

If the other party is overseas the method of service will depend on whether the country is a party to the Hague Service Convention. The Attorney-General's Department keeps a copy of the convention, a list of all convention countries and the details of their central authority. This information is also available from the website for the Hague Conference on Private International Law.

If the country is a Hague Convention country the documents can only be served in a certain way. The Registrar may be able to, and in some cases must, forward the documents to that country which can take many months.

If the country is not a Hague Convention country, normal service is allowed, either personally or by post.

See Family Law Regulations 2024 (Cth) Part 10.

What if I do not know the other party's whereabouts?

If you do not know where to find the other party or for whatever other reason are unable to serve the other party, the Court can order that:

The Court does not usually require you to go to great expense in trying to track down the other party, especially if you are experiencing financial hardship. It is not necessary, for example, to hire a private detective. The following inexpensive inquiries are often sufficient:

To apply for substituted service or dispensation from service, you need to file a separate Application in a Proceeding and an Affidavitsetting out the efforts you have made to find the other party and what, if any, financial hardship you are experiencing. These documents may be filed at the same time as your application or at a later time when it becomes clear that you cannot find the other party.

If you are not represented by a lawyer, it is best to seek legal advice before making either of these applications. Call the free Legal Helpline for advice on 1300 366 424 during business hours.

On what grounds can I oppose a divorce?

There are only very limited grounds for opposing a divorce. It is not enough that you do not want a divorce or you want to get back together. As the only ground for divorce is the irretrievable breakdown of marriage, the only way to stop the divorce is to show that this has not occurred. You must prove either that you have not yet been separated for 12 months or that there is a chance you will get back together.

To prove that there is a chance you will get back together, you must show that both of you want to do so. Of course, this will be difficult if the other party has applied for divorce to end the marriage. You will have a better chance of getting the other party to reconsider if you can arrange, and they agree to attend, a counselling session with a counselling organisation.

What is required to oppose a divorce?

To oppose a divorce you need to prepare, file and serve a Response to Divorce form within 28 days of being served with the Application for Divorce (unless you were served outside of Australia, in which case you have 42 days).

What if I do not oppose the divorce, but there are mistakes in the application?

If you do not oppose the divorce, but there are mistakes in the application, seek legal advice. Call our free Legal Helpline on 1300 366 424 during business hours.

It may be possible to prepare and file an affidavit explaining what facts are wrong in the application, what the true facts are and what evidence supports this. Such an affidavit must be filed at least 7 days before the divorce is listed for hearing.

How much does it cost?

There is currently no fee to file a response opposing a divorce.

Do I have to attend the hearing?

Yes. If you file a Response to Divorce both you and the other party must then attend the hearing.

Who will hear my application?

Divorce applications are usually heard by sessional registrars engaged by the Federal Circuit and Family Court. A registrar is a court lawyer who has been given the power to perform particular tasks, such as grant divorces.

Unless otherwise advised, all divorce hearings will occur via electronic means. Parties will be notified of the details for the electronic hearing in advance of their allocated Court date [Family Law Practice Direction – Divorce proceedings para 4.1].

When will my application be heard?

If either party applies for divorce on their own, it will be listed at least:

[Family Law Practice Direction – Divorce proceedings para 2.21]

Depending on the business of the Court, it may be listed more than 42 or 56 days after you file it. If the Application for Divorce is eFiled, the applicant(s) can choose the next available date on the Commonwealth Courts Portal.

Do I need to attend the hearing?

Generally, if you do not attend the hearing of your application (either electronically or in person), it may be dismissed in your absence.

Parties who have filed for divorce jointly can request that the application be heard without attendance of the parties or their legal representatives. A party who has filed for divorce on their own may also request that it be heard in the absence of the parties, and the Court may grant this request if the proceedings are undefended and the other party does not object to the hearing going ahead without party attendance [Family Law Act 1975 (Cth) s 98A].

If there are children of the marriage under the age of 18 years, the Court must be satisfied that proper arrangements have been made for the care, welfare and development of those children before granting divorce [see s 55A].

Is there anything else I should do before the hearing?

You can double check the date and time of the hearing of your divorce in the Commonwealth Courts Portal or by calling the National Enquiry Centreon 1300 352 000.

What should I do at the hearing?

Information on attending the Court via an electronic hearing can be found on the Federal Circuit and Family Court's Electronic Hearings website.

If the Court requires physical attendance, you should arrive at least 15 minutes early. When you arrive at the court building you should look for the name and number of your case and the number of the courtroom, as there are a number of courtrooms where cases are heard. A list of the cases being heard is displayed in the foyer of the court building. If possible, notify court staff when you arrive at the courtroom. Sit close by the courtroom so that you can hear when your case is called. When your case is called, you will go into the courtroom and sit at the long table (the bar table) facing the Registrar.

The hearing of the divorce is not likely to take more than a few minutes. The Registrar must be satisfied that the other party has been correctly served and that the 12 month separation period and other requirements have been proved.

When will the divorce order take effect?

Once the Registrar is satisfied that the other party has been served and the 12 month separation period has passed (and any other requirements have been met) the Registrar will grant a divorce order.

The divorce order automatically becomes final and takes effect one month and one day later and is usually posted to each of the parties. Technically the parties are still married until the order becomes final, and they cannot remarry until it becomes final. [See Family Law Act 1975 (Cth) s 55(1)(a)]

Can the divorce order take effect any faster?

The one month waiting period can be shortened in special circumstances [Family Law Act 1975 (Cth) s 55(2)(b)].

What if we get back together?

The Court may rescind (cancel) a divorce order before it becomes final if the parties get back together. The parties would need to jointly file an Application in a Proceeding. See Family Law Act 1975(Cth) s 57 and Federal Circuit and Family Court of Australia (Family Law) Rules 2021 (Cth) r 1.09.

What if the other party gave false evidence or forged my signature?

The Court may rescind (cancel) a divorce order before it becomes final if there has been a miscarriage of justice and, if it thinks fit, order that the proceedings be re-heard. See Family Law Act 1975 (Cth) s 58 and Federal Circuit and Family Court of Australia (Family Law) Rules 2021 (Cth) r 1.09.

Can I appeal against a divorce order?

Yes, you can appeal a divorce order by filing an Application for Review within 28 days of the date of the order.

If either party appeals against the terms of a divorce order, the order will be automatically delayed in taking effect until one month after the appeal is heard and determined [see Family Law Act 1975 (Cth) s 55(3)].

No appeal can be made after a divorce order has taken effect and become final [see Family Law Act 1975 (Cth) s 60].

If you are thinking about appealing your divorce order, seek legal advice. Call the free Legal Helpline on 1300 366 424.
