Legal Marriage Requirements in South Australia

If you want to get married in Adelaide or elsewhere in South Australia, the legal requirements come from the Marriage Act 1961 and the current guidelines for authorised celebrants. Here are the essentials in plain English.

Basic Eligibility

Both parties must:

  • be at least 18 years old, unless a court has approved a marriage involving a person aged 16 or 17 in rare circumstances
  • not already be legally married
  • not be marrying a parent, child, sibling, or another prohibited close relative
  • understand the nature of marriage
  • give real consent freely

More detail is on our page about who can get married.

Notice of Intended Marriage

Before the ceremony, you must lodge a Notice of Intended Marriage with your celebrant.

The key rules are:

  • it must be lodged at least one month before the marriage
  • it can be lodged up to 18 months before the marriage
  • both parties must sign it
  • it must be witnessed by an authorised witness
  • the notice period starts when the completed notice is given to the celebrant

If you need help completing or downloading a NOIM, use NOIM Easy.

Identification and Supporting Documents

You must usually provide:

  • a birth certificate or current passport as proof of date and place of birth
  • photo ID
  • divorce papers if previously married and divorced
  • a death certificate if widowed
  • evidence of change of name if your current legal name differs from your birth record

See our guide to ID requirements for a fuller breakdown.

Overseas or Non-English Documents

If a document is not in English, you will usually need:

  • the original document
  • a proper English translation
  • a NAATI-accredited translator, where required

See translation requirements if this applies to you.

Ceremony Requirements

For the marriage ceremony itself, Australian law requires:

  • both parties to be physically present together
  • an authorised celebrant
  • two witnesses aged 18 or over
  • the legal words required by the Marriage Act
  • signatures on the marriage documents after the ceremony

The ceremony cannot be completed online or by proxy. If you are searching for the fastest route, read get married quickly in Adelaide.

Meetings with Your Celebrant

Current celebrant guidance also requires the celebrant to meet each party separately in person before solemnising the marriage. That is separate from the ceremony itself and helps the celebrant confirm identity, consent, and legal capacity.

If You Need to Marry in Less Than One Month

That is only possible if a prescribed authority approves a shortening of time. Approval is limited to specific categories and is never automatic.

After the Marriage

After the ceremony:

  • your celebrant lodges the completed marriage documents
  • you receive a ceremonial certificate on the day
  • the official legal certificate is ordered from South Australian Births, Deaths and Marriages

Our guide to South Australian marriage certificates explains that next step.
