Getting Married in Australia: Legal Requirements, Notice of Intended Marriage and Paperwork

To get married legally in Australia, you give an authorised celebrant a Notice of Intended Marriage (NOIM) at least one month before the wedding, show proof of identity and your date and place of birth, and then marry in front of that celebrant and two witnesses using the words the law requires. That is the whole legal skeleton. Everything else, the venue, the vows, the music, the marquee on the lawn, is yours to design. This guide walks through the paperwork in the order you will meet it, so nothing surprises you six weeks out.

A quick note on how to use it. The rules described here are the general picture, and they can change or have exceptions for individual circumstances. Treat this as your map, and confirm the detail with your celebrant and with the official sources at the end of the article before you rely on any single point.

Who makes the rules for marriage in Australia?

Marriage is regulated by federal law, the Marriage Act 1961. In practice this means the core legal requirements do not change when you cross a state border: a couple marrying in a Tasmanian garden and a couple marrying in a Queensland church are subject to the same basic framework.

What does differ by state and territory is the administrative side. Each has its own Births, Deaths and Marriages registry (BDM), which records marriages and issues official certificates. Councils and land managers also set their own rules for using parks, beaches and public spaces. So the law of the marriage is national, while the paperwork afterwards and the permission to use a particular spot are local.

What is a Notice of Intended Marriage and when do we lodge it?

The Notice of Intended Marriage, usually shortened to NOIM, is the form in which you tell your celebrant that you intend to marry. It is the document the whole legal process hangs on. You complete it and give it to your authorised celebrant, who checks it and keeps it.

The timing rule is simple to state. The celebrant must receive the NOIM no later than one month before the ceremony, and no earlier than eighteen months before it. That window is why couples who book a venue two years out cannot lodge the form at the same time: the earliest you can lodge is eighteen months ahead of the date.

What documents and ID do we need?

Your celebrant must be satisfied of who you are and that you are free to marry. The general requirements are proof of your identity, and proof of your date and place of birth. If you have been married before, you also need documents showing how that marriage ended.

• Proof of identity for each of you, using the forms of identification your celebrant accepts.
• Evidence of your date and place of birth, such as a birth certificate or equivalent. Ask what your celebrant accepts if you were born overseas.
• If you were previously married, the document that ended the earlier marriage, such as a divorce order or a death certificate.
• If a document is in a language other than English, ask your celebrant whether a certified translation is needed.
• Your full legal names exactly as they appear on your documents, because the NOIM should match them.

Different celebrants have different ways of sighting and certifying documents, so ask for their checklist on your first call. It is much easier to order a missing document the week you book than the week before the wedding.

How old do we have to be to marry in Australia?

The minimum age is 18. There is a narrow exception: in some circumstances a court can authorise the marriage of a person who is 16 or 17. That is a legal process with its own requirements, not something a celebrant can simply approve, so anyone in that position should read the official guidance and take proper advice.

Can same-sex couples marry in Australia?

Yes. Marriage between two people of the same sex has been legal in Australia since December 2017, following a change to the Marriage Act. Couples of any gender combination go through the same steps described here: the same NOIM, the same documents and the same ceremony requirements.

What does the ceremony itself legally require?

On the day the law asks for a few specific things, and they are easy to meet. You need an authorised celebrant, two witnesses who are over 18, and the legally prescribed words, which must be spoken during the ceremony. Your celebrant will tell you exactly what they are and where they sit in the order of service.

1. Choose your authorised celebrantThe person who officiates must be authorised to solemnise marriages. A celebrant can also help you draft the ceremony itself.
2. Lodge the Notice of Intended MarriageComplete the NOIM and hand it over with your identity and birth documents, inside the one to eighteen month window.
3. Choose two witnesses over 18Brief them in advance so they know they will sign. Many couples choose a sibling, a close friend or a parent.
4. Say the legal wordsAlongside any personal vows, the prescribed words must be spoken. Your celebrant will guide you through them.
5. Sign the paperworkYou, your witnesses and your celebrant sign the marriage documents at the ceremony.
6. Receive your commemorative certificateThis is the keepsake presented on the day.
7. Order the official certificateApply to the BDM registry of the state or territory where you married.

Who can be our witnesses?

Two people over 18 who are present at the ceremony, can see and hear what is happening, and are willing to sign. Beyond that, you choose. Some couples use the best man and maid of honour, some prefer a parent or grandparent, and some ask guests who have a special place in their story.

Practical tip: ask your witnesses to bring photo ID in case your celebrant wants to confirm their details, and make sure the names they will sign match what is on their ID. Check with your celebrant on any specific requirements, because it is a small detail that causes a delay on the day if it is wrong.

Do we have to say the legal words, and can we write our own vows?

Yes to both, and they are not in conflict. The prescribed legal words are a required part of the ceremony. Your personal vows, readings, music and rituals are on top of that. A good celebrant will fold the legal part into the flow so it feels like part of your story rather than a form being read out.

If you have a strong view on tone, such as keeping it short or having a humorous ceremony, say so at the first meeting. The legal part takes only a few moments, and the rest of the ceremony can reflect you.

What is the difference between the certificate on the day and the official one?

People often assume the pretty certificate handed over at the ceremony is the one the bank will accept. It is not. The certificate presented on the day is commemorative. The official marriage certificate is obtained from the Births, Deaths and Marriages registry of the state or territory in which the marriage took place, normally after your celebrant has lodged the paperwork.

If you plan to change your name, update records or deal with overseas authorities, order the official certificate soon after the wedding. Each BDM registry sets its own fees and processing times, so check the registry website for the state or territory where you married.

What if one of us is from overseas, or we are marrying a long way from home?

Plenty of couples include at least one person who is not an Australian citizen, or who lives overseas. The general steps above still apply, but the details of documents, translations and what your home country will recognise can differ. This article makes no statement about visas or residency, because those are matters for the relevant government authority and your own circumstances.

• Contact your embassy or consulate and ask what documents they want for a marriage abroad, and how the marriage will be recognised at home.
• Tell your celebrant on the first call that a partner is from overseas, so they can list any extra documents.
• Ask about certified translations of any documents not in English.
• Allow extra time for ordering overseas documents, as they can be slow to arrive.
• Keep any immigration questions separate and direct them to the official source.

What paperwork do we deal with after the wedding?

A few small jobs follow the ceremony. The celebrant will send the signed marriage documents to the relevant authority within the time the law specifies, which is part of why you choose someone organised. After that the order of work is straightforward.

1. Check your celebrant has lodged the paperworkAsk them when you can expect the registry to have the record.
2. Order the official certificateFrom the BDM registry of the state or territory where you married.
3. Update your name if you are changing itUse the official certificate for banks, licences, passports and so on, following each organisation’s own process.
4. Update records that matterThink superannuation, insurance, wills, bank accounts and your employer.

A paperwork checklist you can copy

• Book your celebrant and confirm they are authorised to solemnise marriages.
• Ask the celebrant for their document checklist and fee schedule in writing.
• Gather ID and birth documents, and order any that are missing.
• If previously married, find the divorce order or death certificate.
• Lodge the NOIM inside the one to eighteen month window.
• Choose two witnesses over 18 and brief them.
• Talk through the legal words and your personal vows with your celebrant.
• Confirm any venue or council permit separately from the legal paperwork.
• After the wedding, order the official certificate from the BDM registry.

Once the legal side is settled, the question left is how to keep everybody informed. A Weddtap wedding page can hold the date, the location, the timings and the practical information for your guests in one place, which saves repeating the same answers in a dozen messages.
