In a sentence
The NOIM is the legal notice that you and your partner intend to marry. It must reach an authorised celebrant or state registry at least one calendar month and one day before the ceremony, signed by both partners in front of a prescribed witness, with valid identity and prior-marriage documents.
The six-step process.
Same process whether you marry in a backyard, a winery, a registry office, or on a beach. The only thing that changes is who you choose as your celebrant.
Choose your celebrant or registry office
Your NOIM must be lodged with the same authorised marriage celebrant who will conduct your ceremony, or with the state Registry of Births, Deaths and Marriages if you are marrying through the registry. You cannot lodge with one celebrant and marry under another without re-lodging.
Complete the form
The official form is published by the Attorney-General's Department. Most celebrants will email or hand you a fillable PDF. Both partners must complete their sections — full legal names, dates and places of birth, current addresses, parents' names, occupations, and any prior marriages.
Sign in front of an authorised witness
Each partner signs the NOIM in front of one of the prescribed witnesses: an authorised marriage celebrant, a Justice of the Peace, a barrister or solicitor, a medical practitioner, or a member of the police force. If you are overseas, an Australian Consular Officer or Notary Public can witness it.
Submit at least one full calendar month before the ceremony
The NOIM must be received by your celebrant or registry no later than one calendar month and one day before the ceremony. Submit early — the only thing the one-month rule cannot do is shorten itself, even by a single day.
Provide identity and prior-marriage documents
Your celebrant will verify your identity (passport, birth certificate, or driver's licence) and proof of the end of any prior marriage (divorce certificate, decree absolute, or death certificate of a former spouse). Keep originals — the celebrant only needs to sight them.
Sign the Declaration of No Legal Impediment
On or shortly before the wedding day, both partners sign a separate document — the Declaration of No Legal Impediment to Marriage — confirming nothing has changed since lodging the NOIM. Then comes the ceremony itself.
Documents required.
| Document | Notes |
|---|---|
Birth certificate OR passport | For each partner. Must show current legal name. Driver's licence accepted only if you also show another evidence-of-age document. |
Photo identification | Passport or driver's licence — required even if you also show a birth certificate. |
Divorce certificate (if applicable) | Required if either partner was previously married. The court-issued decree absolute or divorce order. Foreign divorces may need additional verification. |
Death certificate of former spouse (if applicable) | Required if either partner was widowed. Original or certified copy. |
Permission of court (under-18s) | A person aged 16 or 17 cannot marry without an order from a magistrate. The other party must be over 18. |
Common mistakes.
Most NOIM problems land in the final fortnight before a wedding. Avoiding them is mostly about lodging early and double-checking documents long before you need to.
Lodging less than one calendar month out
The one-month rule is enforced by federal law. Only the Registrar of Births, Deaths and Marriages can shorten it, and only in narrow circumstances (employment, defence, medical, religious, or other). A simple "we forgot" is not grounds.
Missing or out-of-date identity documents
A driver's licence on its own is not enough — you also need either a passport or a birth certificate. If your name on the NOIM does not match your ID exactly, the celebrant cannot proceed.
Forgetting prior-marriage paperwork
Even an overseas marriage that ended decades ago requires evidence of dissolution. Couples often discover this two weeks out. Sourcing certified foreign divorce records can take 4-12 weeks.
Lodging with the wrong celebrant
If you change celebrants after lodging, you must re-lodge with the new celebrant — and the one-month clock restarts. Pick your celebrant before lodging the NOIM.
Skipping the Declaration of No Legal Impediment
This is a separate document from the NOIM, signed close to the wedding. Couples often think the NOIM covers it. Your celebrant will prompt you, but check.
Frequently asked questions.
Up to 18 months before the ceremony. There is no penalty for lodging early. Most couples lodge 3-6 months out, alongside booking their celebrant.
