To marry in South Australia, both parties must be at least 18 years old (or 16–17 with a court order and parental consent), must not be in a prohibited relationship, must give a Notice of Intended Marriage (NOIM) to an authorised celebrant no less than one month before and no more than 18 months before the ceremony, and must be married by an authorised celebrant in front of two adult witnesses. The marriage is then registered with Births, Deaths & Marriages (Consumer and Business Services, SA). These obligations flow from the Marriage Act 1961 (Cth), which applies uniformly across Australia, including South Australia.
Your immediate next steps:
- Check age and consent. Both parties must be 18 or older, or have a court order if aged 16–17.
- Gather identity documents. Passport or birth certificate showing place of birth, plus current photo ID.
- Book an authorised celebrant and lodge the NOIM at least one month before the ceremony date.
- Confirm two adult witnesses (18+) who will attend the ceremony and sign the marriage certificate.

Who is legally allowed to marry in South Australia?
The standard rule under the Marriage Act 1961 (Cth) is straightforward: both parties must be 18 or older. A person aged 16 or 17 may marry only with written parental consent and a court authorisation from the Magistrates Court. No one under 16 may marry under any circumstances.
Neither party can already be married to someone else. A marriage entered into while a previous marriage is still legally in force is void, and the parties may face criminal consequences.
Prohibited relationships are defined in Section 23B of the Marriage Act. A marriage is void if the parties are related as ancestor and descendant (parent, grandparent, child, grandchild) or as siblings, whether of the whole or half blood. These prohibitions extend to relationships created through adoption. Cousins, however, are not prohibited from marrying under Australian law.
Real, voluntary consent is also a legal requirement. A celebrant has a duty to meet each party separately before the ceremony to confirm that both understand what they are agreeing to and are marrying freely. A marriage obtained by duress, fraud, or where one party lacks mental capacity is not valid.
What is the Notice of Intended Marriage and when must you lodge it?
The NOIM is the formal document that starts the legal marriage process in Australia. Under the SA government’s marriage guidance, the timing rules are fixed:
- Earliest lodgement: No more than 18 months before the intended ceremony date.
- Latest lodgement: No less than one calendar month before the ceremony date.
- Give the NOIM to your celebrant. The form goes directly to the authorised celebrant who will solemnise the marriage, not to a government office. The celebrant then manages lodgement with the state registry.
- Signing in Australia. Both parties must sign the NOIM in the presence of an authorised witness — typically the celebrant, a justice of the peace, a medical practitioner, a pharmacist, a police officer, a lawyer, or a teacher.
- Signing overseas. If a party is outside Australia when signing, the NOIM must be witnessed by an Australian consular officer or a notary public. Confirm this with your celebrant before travelling.
- Audio-visual witnessing. In specific circumstances, a party who cannot be physically present may sign via audio-visual means, but this must be confirmed with the celebrant early, as not all celebrants are set up to facilitate it.
If your circumstances mean you cannot give the NOIM a full month before the ceremony, do not simply proceed. Contact an authorised celebrant immediately, as there is a formal process for urgent weddings covered later in this guide.
What documents do you need to provide with the NOIM?
Gathering the right documents is where many couples lose time. The South Australian Law Handbook and the Attorney-General’s Department set out the following requirements.
Proof of birth and identity:
- A passport showing your date and place of birth is the most straightforward option.
- A birth certificate is also accepted, but you must also bring current photo ID (driver’s licence or passport) when presenting it.
- Passports must show your place of birth, not just your nationality. A passport that lists only nationality may not satisfy registry requirements, so check yours before the appointment.
If born overseas without a birth certificate:
You may provide a statutory declaration of your date and place of birth, supported by any other available documents. Any document not in English must be accompanied by a certified translation prepared by a NAATI-accredited translator.
If previously married:
- A divorce decree absolute is required if your previous marriage ended in divorce.
- A death certificate is required if your previous spouse has died.
- In some cases, an earlier marriage certificate is also needed to trace name changes through official records.
Certified copies:
Your celebrant will advise whether they need original documents or certified copies. A Justice of the Peace, lawyer, or police officer can certify copies in South Australia.
Pro Tip: Start gathering documents at least three months before your wedding date. Overseas birth certificates, certified translations, and divorce decrees can take weeks to obtain, and a delay in documents means a delay in lodging the NOIM, which can push back your ceremony date.
Who can solemnise a marriage in South Australia, and where can you marry?
Under the Marriage Act 1961 (Cth), only certain people are authorised to solemnise a marriage. In South Australia, these are:
- Authorised civil celebrants registered with the Attorney-General’s Department
- Ministers of religion registered under the Marriage Act
- The Registrar of Marriages (Consumer and Business Services, SA)
- Persons specially authorised by the Attorney-General in prescribed circumstances
Marriages can be solemnised at any location and at any time, provided the legal requirements are met. There is no requirement to marry in a church, registry office, or any particular type of venue. A beach, a winery, a heritage building, or a private garden are all legally valid settings, as long as two adult witnesses are present and the prescribed words are spoken.
Registry office vs independent authorised celebrant
| Feature | Registry office (CBS, SA) | Independent authorised celebrant |
|---|---|---|
| Who solemnises | Registrar of Marriages | Authorised civil celebrant of your choice |
| Location | Registry office premises | Venue of your choice |
| Booking flexibility | Set appointment times, limited availability | Flexible; celebrant works around your schedule |
| Ceremony style | Standard civil ceremony | Fully personalised |
| NOIM lodgement | Lodged with the registry directly | Lodged by the celebrant with the registry |
| Fees | Government fee schedule applies | Celebrant sets their own fee |
The registry office wedding service through Consumer and Business Services is a practical option for couples who want a simple, low-cost ceremony. Independent celebrants offer more flexibility in location, timing, and ceremony content, which suits couples who want a personalised experience at a venue of their choosing.
What must happen during the ceremony for the marriage to be legal?
A valid marriage ceremony in South Australia requires several specific elements, all set out in the Marriage Act 1961 (Cth).
- Two adult witnesses (both aged 18 or older) must be present throughout the ceremony and must sign the marriage certificate immediately after the solemnisation.
- Prescribed declarations must be spoken by both parties. The celebrant will guide you through the exact wording, but both parties must state that they know of no lawful impediment to the marriage and must take each other as lawful spouses.
- The celebrant must have met each party separately before the ceremony to verify identity and confirm genuine, voluntary consent.
- Three copies of the marriage certificate are prepared: one for the couple (the commemorative certificate), one for the registry, and one retained by the celebrant.
- The celebrant signs the certificate along with both parties and both witnesses immediately after the ceremony.
After the ceremony, the celebrant is legally required to forward the official paperwork to the Registrar of Births, Deaths and Marriages within 14 days.
Pro Tip: Choose your two witnesses carefully and confirm their attendance well before the wedding day. If a witness cannot attend, you will need a replacement who is 18 or older. Keep your signed commemorative certificate in a safe place, but remember it is not the official registered certificate — you will need to order that separately from Births, Deaths & Marriages.
What happens after the ceremony: registration and ordering your certificate
The celebrant’s obligation
Under the Attorney-General’s Department guidance on the NOIM process, the celebrant must forward all required paperwork, including the official marriage certificate and declarations, to the Registrar of Births, Deaths and Marriages within 14 days of the ceremony. This is a statutory obligation, not a courtesy.
Commemorative vs registered certificate
The certificate you receive on the day is a commemorative certificate. It is a meaningful keepsake, but it is not the document that government agencies, banks, or immigration authorities will accept as legal proof of marriage. For those purposes, you need an official registered marriage certificate issued by Births, Deaths & Marriages (CBS, SA).
You can order the registered certificate directly from Consumer and Business Services once the celebrant has lodged the paperwork. Allow time for the celebrant to lodge and for the registry to process the registration before ordering.
Key statutory timeframes
| Milestone | Timeframe |
|---|---|
| Earliest NOIM lodgement | 18 months before the ceremony |
| Latest NOIM lodgement | 1 calendar month before the ceremony |
| Celebrant lodges paperwork with registry | Within 14 days after the ceremony |
Can someone aged 16 or 17 get married in South Australia?
Yes, but the legal path is more involved. The Marriage Act 1961 (Cth) permits a person aged 16 or 17 to marry under strict conditions:
- The proposed spouse must be 18 or older.
- Written parental consent must be provided by the appropriate parent or guardian, witnessed in accordance with the Act’s requirements (Schedule 1 sets out who must consent).
- A court authorisation from the Magistrates Court is required in addition to parental consent.
If a parent refuses consent, the minor or the other party may apply to a magistrate or judge, who has the power to give consent in place of the parent if satisfied the marriage is in the minor’s best interests.
Consequences of skipping these steps are serious. A marriage involving a minor that proceeds without the required consent and court order is void. The celebrant and any other parties involved may also face criminal penalties under the Act.
If you are in this situation, the practical steps are: obtain written parental consent first, then file an application with the Magistrates Court. An authorised celebrant can guide you through the documentation required for the court application.
What if you need to marry in less than a month?
The one-month minimum NOIM period can be shortened in prescribed circumstances. These are set out in the Marriage Act 1961 (Cth) and include:
- Medical necessity, where one party has a serious illness or is facing imminent death.
- Employment or travel obligations, such as a party being deployed overseas or required to relocate for work at short notice.
- Legal proceedings that require the parties to be married before a specific date.
- An error in giving notice, where the NOIM was lodged with the wrong celebrant or contained an error that requires a fresh notice.
To apply for a shortened notice period, contact an authorised celebrant immediately and explain the circumstances. The celebrant will direct you to the appropriate prescribed authority, which in South Australia is typically a magistrate or a person authorised under the Act. You will need to provide documentary evidence supporting the urgent reason.
Pro Tip: Do not wait until you are within a week of the intended date to raise an urgent situation with your celebrant. The application process takes time, and the prescribed authority needs to be satisfied by the evidence. Raise it as soon as you know the circumstances, and bring every relevant document you have.
A practical timeline for getting married in South Australia
Following a clear timeline keeps the legal steps manageable and avoids last-minute pressure. Use this as your planning framework alongside the wedding planning checklist for South Australian couples.
- Three months before the wedding. Start gathering all identity and birth documents. If you were born overseas, request certified copies and arrange NAATI-accredited translations now. If previously married, obtain your divorce decree absolute or death certificate.
- Six to eight weeks before. Confirm your authorised celebrant is booked and has received or is ready to receive your documents. Finalise your venue and confirm it can accommodate two adult witnesses and the ceremony requirements. Check your passport shows your place of birth.
- At least one month before (mandatory). Lodge the NOIM with your celebrant. Both parties must sign in front of an authorised witness. Do not leave this step until the last possible day.
- One to two weeks before. Confirm your two witnesses, their full names, and their attendance. Provide any outstanding documents to your celebrant.
- Ceremony day. Both parties and both witnesses sign all three copies of the marriage certificate immediately after the ceremony. You receive the commemorative certificate on the day.
- Within 14 days after the ceremony. The celebrant lodges the official paperwork with Births, Deaths & Marriages (CBS, SA). Once lodged, you can order your registered marriage certificate from the registry.
Pro Tip: Scan and save digital copies of every document you provide to your celebrant, including your NOIM, birth certificates, and any divorce or death certificates. Store them in a secure cloud folder. If originals are lost or damaged, having clear scans speeds up any replacement process significantly.
A note on common pitfalls from local wedding professionals
The legal framework for getting married in South Australia is clear, but a handful of practical mistakes come up repeatedly among Adelaide couples.
The most common is the passport place-of-birth issue. Many couples assume their passport covers all identity requirements, only to discover it does not list a place of birth, just a nationality. The SA registry requires place of birth to be documented, so check your passport the moment you start planning, not the week before the NOIM is due.
Late NOIM lodgement is the second recurring problem. Couples who book their venue first and their celebrant second sometimes find their preferred celebrant is unavailable, which pushes the NOIM lodgement dangerously close to the one-month minimum. Book your celebrant as early as you book your venue.
Foreign document certification is the third area where delays happen. A birth certificate from another country needs a NAATI-accredited translation and, in some cases, an apostille. Both take time. Couples who leave this until six weeks out regularly find themselves scrambling.
Finally, if one party will be signing the NOIM remotely, confirm with your celebrant early whether they can facilitate audio-visual witnessing. Not all celebrants offer this, and finding out late can require switching celebrants entirely.
