How to change your last name once you’re married

A common question that crops up with newly-married brides relates to the hassle of changing their last name. In New Zealand we are actually pretty lucky – the marriage certificate itself is proof enough, so there’s not too much paperwork to do. The main thing that takes a bit of time and paperwork is getting your name changed with all the different organisations you’re associated with.

How to change last name once you’re married?

Simply put – it’s done for you when you sign on the dotted line (the marriage license that is). You are free to use both your maiden name and your married name. Just remember which name you’re using for what government departments and different things as it can be confusing for them and you.

What documents need changed over to my married name?

The two forms that you, your witnesses and your celebrant sign on your wedding day are called ‘The Particulars of Marriage’.  Some places, even some banks, will let you use this when you want to go in and change your name. You don’t even need to send the form in for your Passport, you just tell them your wedding date! (You do have to pay for it to be reissued, at $180 though).

If you are needing to change your name on your driver’s licence, you will need to order an actual ‘Marriage Licence’, using the form on the back of your Particulars of Marriage (and for an additional cost of just over $20). 

Tips for changing your last name when you get married:

Your driver’s license and passport are two of the big ticket legal documents with your maiden name on them (if you have them). You can either wait till they expire, and update them with your married name at that point. Or, you can pay for them to be reissued with your new name, if you just can’t wait.

Be really careful with the names you book any flights under – if you book your honeymoon under your married name but your passport still uses your maiden name, you will have trouble travelling.

For your household bills and correspondence, I recommend giving the companies a ring or flicking them an email as the need arises. Some places want a certified copy of your marriage certificate. I simply copied my marriage certificate 5 or so times, then took it to a JP to get them to certify it was a true copy. That way, I had copies on hand to send out to organisations who needed that extra bit of paperwork. A couple of places even accepted a scanned version, so ask if that’s ok.

One bit of documentation that’s still in my maiden name is my house title and rates bills. The names listed on your rates bills come directly off your Certificate of Title, which (very simply put) is the paperwork which states who owns a house. To get your name changed on the Certificate of Title, you need to go through your lawyer. Not something I’ve worried about doing, since it’ll incur extra fees. Next time we buy a house I can sort it out.

  1. I’ve recently got married and want to take on my husband’s last name. We have a marriage certificate. Do I need to change my name before I apply for a passport or can I just use the marriage certificate as proof? Also do I need to change my name on my drivers license aswell for this??

    1. You use the marriage certificate as proof of changing your last name and no, you don’t need to change your name on your drivers license xx

    2. Hi I just redid my passport online. All they need is Yr wedding details date place etc and they will sned u a new one for $191

  2. What about your signature? Can you keep using your old one, or if you want to change it to reflect your married name can you do this?

  3. I want to take my husbands last name and not my maiden name anymore. Do I have to go in and change it myself and pay for it or is it legal for me to just use it? Do I need to change my ird number?, If I want nothing to do with my maiden name anymore?
    I have to change everything includes my bills and anything else that’s under my name right?

    1. Hi Faailoga, you can just use your maiden name. You don’t need to change your IRD number. You’ll need to contact each place with your maiden name listed, and ask for them to change it (you may have to provide proof, such as your marriage certificate – they’ll let you know what they need) xx

    1. When you renew your passport, the form asks you if you’ve changed your name and then talks you through it. It’s pretty easy x

  4. Great info – just one correction. As a wedding celebrant, I need to clarify something. The two forms you sign on your wedding day are strictly-speaking, known as The Particulars of Marriage. While many places, even some banks, will let you use this as the documentation to prove you are married when you want to change the name you use, many (including the Passport Office and the NZTA) require you to have your actual Marriage Licence. This has to be ordered, for an additional $20+, using the form on the back of your Particulars of Marriage. Why this is so baffles me, but such is life!

    1. Thanks Honor, that’s something new since I had to change my last name – I have added your new information into the article. Many thanks, Amanda
