Congratulations my friends, you've sealed the deal and you're officially, legally, gloriously married! If you were married in NSW and you're taking your partner's surname, giving them yours, or joining the two together into a very fancy double-barrelled moniker, here's the good news first… changing your surname after marriage in NSW is free, you don't need to register a formal change of name, and the whole thing starts with one piece of paper: your official marriage certificate from NSW Births, Deaths and Marriages.
I'm Bec, a Cert IV qualified marriage celebrant who has married more than 200 couples across the Central Coast, Hunter Valley, Newcastle and Sydney, and I've walked an awful lot of newlyweds through this exact bit of life admin. So pop the kettle on (or raise that leftover Mojito to your lips, honeyoomners) and let me show you the order that makes it all fall into place.
How to change your name after marriage in NSW: the quick answer
Get your official marriage certificate from NSW Births, Deaths and Marriages (not the pretty one you signed on the day, that’s the commemorative Form 15).
Update your NSW driver licence at a Service NSW centre.
Update your Medicare card by phone or at a Services Australia centre.
Use those three documents to change your name everywhere else, including your passport, ideally once you're home from the honeymoon.
That's the whole recipe, and the NSW Government's own name change guidance lays it out in that same order. Now let's walk through each step properly.
Step 1: Order your official NSW marriage certificate
Your official marriage certificate is the only certificate that proves your marriage for a name change. The beautiful certificate you sign during the ceremony (celebrants call it the Form 15) is a lovely keepsake for the frame on the hallway wall, but it's ceremonial, and no government department will accept it as proof of your new name.
After your wedding, your celebrant has up to 14 days to register your marriage with NSW Births, Deaths and Marriages. Once it's registered, you can order the official certificate, and it'll arrive folded in an envelope looking a little less glamorous than the one from your big day, but with all the legal muscle you need.
Here's what it costs and how long it takes, according to the NSW Registry's marriage certificate page:
Standard certificate: $70, including $11 postage and handling.
Priority service: $105 for online applications.
Ordered by your celebrant at registration (within 2 months): up to 3 weeks to process, plus 5 to 7 days for Australia Post to deliver.
Ordered online yourself: up to 3 weeks standard, or up to 2 weeks priority.
When I register a marriage I do it online, which is the quickest way, and if your package includes it I'll order your official certificate for you at the same time, or send you the link so you can order it in your own sweet time.
Step 2: Update your NSW driver licence at Service NSW
Take your official marriage certificate and your current driver licence to any Service NSW centre and ask them to update your licence to your married name. Tell them you just got hitched, show them your wedding highlights reel, offer them a slice of leftover cake… on second thoughts maybe keep the cake, they may not like chocolate. Once it's approved, your new licence is posted to you within 1 to 2 weeks.
If your licence was issued in another state, head to that state's licensing authority instead.
Step 3: Update your name with Medicare
Call the Medicare program line on 132 011 with your official marriage certificate handy, or visit a Services Australia centre, and they'll update your name and post you a new card. You'll need to prove your identity on the phone, and just like everywhere else, a ceremonial certificate won't cut it. Services Australia's Medicare personal details page has the full list of documents they'll accept.
A little honesty from me: older name change guides (including an earlier version of my own, cheeky me) mentioned emailing Medicare to do this. That’s old. Services Australia now points you to the phone line or a service centre, so that's the way to go.
Once you've got your official certificate, new licence and new Medicare card, you're holding the golden trio, and most organisations will happily update your name when they see them.
Step 4: Your name change after marriage checklist
Work through a few of these each week, or use each bill and letter that lands in your inbox as your prompt to update that company. Some will want to see your golden trio, and plenty will take your word for it with a quick online form.

How to change your passport name after marriage
If your family name changed because you got married and your current Australian passport expires more than 2 years from now, the Australian Passport Office will waive the application fee for a replacement passport in your new name. The replacement keeps the same expiry date as the passport it replaces, so it's a straight swap rather than a fresh 10 years.
To link your old and new names you'll generally show your Australian birth certificate or citizenship certificate along with your official marriage certificate. The Australian Passport Office name change page explains it all, and their advice is to allow at least 6 weeks for your new passport to arrive.
My honeymoon advice: travel in your pre-marriage name
If your overseas honeymoon is coming up soon, I recommend booking and travelling in your pre-marriage name for everything: passport, flights, hotels, visas… I repeat, EVERYTHING. Your bookings need to match the passport you're actually holding at the airport.
I can tell you this from personal experience. I got very excited and booked some of our honeymoon in my shiny new name (couldn’t wait to turn that Page… get it?), and without proof of that name that was acceptable in that country, it was a genuine pain in the butt. Learn from my enthusiasm, lovebugs, and apply for the new passport once you're home with a tan and a camera roll full of sunsets.
Your surname options after marriage in NSW
In NSW, your official marriage certificate covers three surname options, and anything else needs a formal change of name. Here's how it breaks down:
Take your partner's surname: covered by your marriage certificate, free.
Your partner takes your surname: works exactly the same way, for every couple, free.
Hyphenate your names: combining both surnames with a hyphen is covered by your marriage certificate, free.
Anything else: a brand new surname (hello Mrs Abso-Legend and Mr Chumpy-Champ), or changing your first name, needs an official change of name through NSW Births, Deaths and Marriages. There's a fee, and you can only do it once in any 12-month period and 3 times in your lifetime, so choose that superhero name wisely… and please tell me all about it when you do.
Married overseas? NSW says you'll need an official change of name to update your surname, which is one of the reasons I always suggest couples sort the legal side at home before a destination wedding.
And just quietly, you don't have to change your name at all. Keeping your own name is just as valid and just as romantic.
One more thing: update your will
In NSW, getting married generally revokes an existing will, unless that will was made in contemplation of your marriage, under section 12 of the Succession Act 2006 (NSW). It's a very unsexy item to add to your newlywed to-do list, but a quick chat with your lawyer about a fresh will in your new name is one of the most loving bits of admin you'll ever do for each other.
Name change after marriage FAQs
Is it free to change your name after marriage in NSW?
Yes. If you were married in Australia, you can change your surname using your official marriage certificate without paying for a formal change of name. You'll just pay for the certificate itself, which is $70 for a standard NSW certificate.
How long does it take to get a marriage certificate in NSW?
Up to 3 weeks to process on the standard service (up to 2 weeks priority if you order online), plus 5 to 7 days for postage. Your celebrant has up to 14 days after the wedding to register your marriage first.
Can I use the certificate we signed at our wedding to change my name?
No. That's the ceremonial certificate. Every department needs the official certificate issued by NSW Births, Deaths and Marriages.
What should I update first after getting married?
Your official marriage certificate first, then your NSW driver licence, then Medicare. Those three documents make every other update much easier.
Can a husband take his wife's surname in NSW?
Absolutely. Either partner can take the other's surname, and you can hyphenate both, using the same marriage certificate.
Can I change my first name when I get married?
No, a marriage certificate only covers your surname. To change your first name you'll need to apply for a formal change of name with NSW Births, Deaths and Marriages.
Do I have to change my name after marriage?
Not at all. It's entirely your choice, and there's no deadline if you'd like to decide later.
Still planning the wedding part?
If you're reading this ahead of time (gold star for organisation), I'd love to help with the bit that comes before all the paperwork. Every Full Page ceremony includes all the legal bits handled properly, from your Notice of Intended Marriage right through to registering your marriage, so the only name you'll be worrying about on the day is the one you're about to share.
Check if I'm free for your date and let's make your ceremony everyone's favourite part of the day.
So much love,
Bec xx
