How Sarah changed her name after getting married overseas

Categories:

How to/resources

Sarah is an Australian citizen born in Western Australia. Sarah moved to Canada temporarily where she recently got married. Sarah has now returned to Perth and wants to update the name on her WA driver’s licence and other transport records.

Sarah received a Canadian marriage certificate, but she discovers that it can’t be used to prove her identity for a name change in WA. She needs to show documents that link her birth name to her new married name.

Next steps for Sarah to change her name

Step 1: Collecting the Right Documents

To meet DTMI requirements, Sarah needed to provide Primary and Secondary proof of identification documents. Sarah notes the documents she must bring must include a signature. After reading the list of documents Sarah chooses to bring in:

  • Her current Australian passport (primary POI)
  • Her bank debit card (secondary POI with her signature)

Sarah is also required to bring in a completed Change of Personal Details form and Linking Documents that connect her maiden name to her married name.

Form C4 – Change of Personal Details

Sarah completes a Change of Personal Details - Form C4 [PDF 261kb] to formally request her name change.

Linking Document

Because Sarah was born in WA, she contacted the WA Registry of Births, Deaths and Marriages to get a Change of Name Certificate. This document officially connects her birth name to her married name and is accepted by DTMI.

Step 2: Visiting a DTMI service centre

With all her documents ready, Sarah visited a DTMI service centre. She brought with her:

  • Her completed Form C4 Change of Personal Details
  • Her Primary and Secondary Proof of Identity documents
  • The WA-issued Change of Name Certificate 

After submitting everything in person, her name was successfully updated in the DTMI system.

There is no fee to process the name change itself, but Sarah is required to pay $33.30 for a replacement driver’s licence card.

The Outcome

Sarah's name was successfully updated in the DTMI system. She received a new driver’s licence showing her married name and updated signature.

Key Takeaways

  • If you were born in WA and got married overseas, you’ll need a Change of Name Certificate from the WA Registry to update your name.
  • You must complete the process in person at a DTMI service centre, regional DTMI office, or authorised agent.
  • Overseas marriage certificates alone aren’t enough to verify your identity for a name change.
