The Legal Side of Saying "I Do" — What Every Australian Couple Needs to Know

So, you're engaged — congratulations! You've got the ring, maybe a Pinterest board that's growing by the hour, and a heart full of excitement. But before you dive headfirst into florals, venues, and the perfect dress, there's one part of wedding planning that every couple in Australia absolutely needs to get right: the legal side of your marriage. Don't worry, though, it's not as daunting as it sounds, and with the right wedding celebrant by your side, it can actually be a beautifully smooth part of your journey together.

Whether you're dreaming of an intimate wedding at home in New Farm, a lush garden ceremony in Toowong, a celebration overlooking the water at Southport, or something gloriously simple, this guide walks you through everything you need to know about the legal considerations for your wedding ceremony in Australia.

The Notice of Intended Marriage (NOIM) — Your First Step

The very first legal step in getting married in Australia is completing a Notice of Intended Marriage, commonly known as a NOIM. This document must be lodged with your celebrant at least one calendar month before your wedding date, but no more than 18 months prior.

Your marriage celebrant will provide you with the NOIM form, and it needs to be signed in front of an authorised witness, such as your celebrant, a Justice of the Peace, a police officer, or an Australian Consular Officer if you're overseas. You'll also need to provide proof of identity (such as a passport or birth certificate) and, if applicable, evidence that any previous marriage has ended, whether through divorce or the death of a former spouse.

For couples planning ahead, especially those booking popular dates across Brisbane City, Windsor, Chermside, or popular Gold Coast locations like Helensvale and Coomera, lodging your NOIM early is always a great idea.

The Declaration of No Legal Impediment to Marriage

On the day of your wedding ceremony, both you and your partner will be asked to make a verbal declaration that you know of no legal reason why you cannot marry each other. This is a standard part of every registered marriage in Australia and your celebrant will guide you through it, gently and naturally, as part of your ceremony.

The Marriage Monitum — Words Required by Law

Australian law requires that your celebrant speak specific words, known as the monitum, during the ceremony. Your celebrant is legally required to say something along the lines of: "I am duly authorised by law to solemnise marriages according to law. Before you are joined in marriage in my presence and in the presence of these witnesses, I am to remind you of the solemn and binding nature of the relationship into which you are now about to enter."

At Let's Marry, these words are woven into your ceremony in a way that feels warm and personal, not like a legal disclaimer read from a form. It's one of the many reasons why working with a caring, experienced celebrant makes all the difference.

The Vows — What the Law Requires

Your vows are the heart of your wedding ceremony, and while you absolutely have the freedom to personalise them, Australian law does require that certain words are included. Each partner must say words to the effect of: "I call upon the persons here present to witness that I, [name], take you, [name], to be my lawful wedded wife/husband/spouse."

Everything else? That's yours to craft. From deeply personal promises to a touch of humour, your celebrant can help you write vows that are entirely and beautifully you.

Witnesses — Who Needs to Sign?

Every marriage in Australia requires two adult witnesses (aged 18 or over) to be present at the ceremony and to sign the marriage documents. They don't need to be related to you — they simply need to be present and willing to sign. Most couples choose close friends or family members, but if you're planning a very small or private wedding, your celebrant can sometimes help arrange witnesses.

This is especially relevant for couples planning a legals only wedding in Brisbane or a legals only wedding on the Gold Coast, where the ceremony is intentionally intimate and the witness list is often kept to just two people.

The Marriage Certificate — What Happens After the Ceremony

After your wedding ceremony, three copies of the marriage certificate are signed: one for you, one for your celebrant, and one that is registered with the Births, Deaths and Marriages registry in your state. Your celebrant handles the registration process on your behalf, which is one less thing you need to think about.

Please note that the certificate signed on the day is the official celebrant's copy for registration purposes. The decorative certificate often displayed in homes is a keepsake, not a legal document. If you need an official certificate for legal name change purposes or other administrative matters, you'll need to order one through the Births, Deaths and Marriages registry in Queensland (or the relevant state).

Legals Only Weddings — Simple, Intimate, and Still Completely Official

Not every couple wants a big production, and that is perfectly wonderful. A legals only wedding is a simple, intimate ceremony that fulfils all of the legal requirements of a registered marriage in Australia without the fanfare. It's often chosen by couples who want to make it official privately before celebrating with family and friends at a later date, or by those who simply prefer something quiet and deeply personal.

At Let's Marry, legals only weddings are conducted with just as much care and warmth as any full celebration. Whether you'd love a quick and beautiful ceremony in your backyard in Auchenflower, a quiet moment in a park in Kedron, or a private exchange at a venue in Eight Mile Plains or Rochedale, every couple deserves a ceremony that feels meaningful.

Weddings Without Reception — A Growing Trend

Closely related to the legals only concept is the idea of a wedding without a reception. More and more couples, particularly those aged in their late twenties and early thirties, are choosing to skip the traditional reception entirely, directing their budget instead toward a stunning honeymoon, a first home deposit, or a celebration that feels more authentically them. A private wedding, perhaps at home, in a garden, or at a low-key venue, followed by a relaxed dinner with close family and friends, is fast becoming one of the most popular ways to tie the knot.

If this sounds like you, a wedding celebrant who truly listens and crafts a ceremony that reflects your personalities is the most important booking you'll make.

Celebrant Fees — What to Expect

One question couples often ask is: what are the typical wedding celebrant fees in Australia? Fees can vary depending on the experience of the celebrant, the complexity of the ceremony, travel requirements, and whether you're booking a full ceremony or a legals only package.

As a guide, marriage celebrant fees in Australia generally range from a few hundred dollars for a simple legals only ceremony through to well over a thousand dollars for a fully customised, ceremony-only experience with rehearsal, personalised vows, and ceremony coordination.

At Let's Marry, there are packages to suit a range of needs and budgets, including celebrant, Emcee, and DJ packages that bundle everything beautifully together. It's also worth knowing that Let's Marry is proud to be a finalist in the 2025 Australian Bridal Industry Awards in the Wedding Celebrant Division, as well as a national finalist in the 2025 Bx Business xCellence Awards in the Wedding Division — recognition that speaks to the heart and dedication that goes into every single ceremony.

Choosing the Right Wedding Celebrant for You

Your celebrant is the person who will guide your ceremony, hold the legal documents, tell your love story, and set the tone for one of the most significant moments of your life. Choosing someone who genuinely connects with you as a couple is so important.

If you're searching for a wedding celebrant in Brisbane, across suburbs like Newstead, Teneriffe, Sunnybank, Mount Gravatt, Carindale, or Loganholme, or looking for a wedding celebrant on the Gold Coast in areas like Upper Coomera, Labrador, or Southport, Let's Marry brings warmth, professionalism, and genuine joy to every ceremony.

As a Brisbane wedding celebrant and Gold Coast wedding celebrant who truly believes that love deserves to be celebrated, Let's Marry is here to make sure the legal side of your big day feels just as beautiful as everything else.

A Quick Legal Checklist for Your Wedding

To summarise the key steps for a legally recognised marriage in Australia:

Provide proof of identity documents to your celebrant.

Provide evidence of any previous marriage ending, if applicable.

Arrange two adult witnesses to be present on the day.

Say the required monitum and vow wording during the ceremony.
