If you have legally changed your name—whether due to marriage, divorce, or another formal reason—it is important to update your bank account details. This ensures your records remain accurate and that your banking services, such as cards and chequebooks, match your current legal identification. For security and compliance, NAB requires verification of your identity to process a change of name, which typically involves providing specific supporting documentation.

Because your name is a primary identifier for your financial profile, these updates generally require a visit to a local branch. This allows staff to sight your original documents and securely update your records. Planning your visit in advance and having the correct paperwork ready helps ensure the process is completed without unnecessary delays.

Steps to Update Your Name

To change your full legal name with NAB, you are required to visit a NAB branch in person. This process involves a re-verification of your identity to maintain the security and integrity of your banking records.

Required Documentation

When visiting a NAB branch to update your name, please bring the following original documents:

  • Primary Identification: A government-issued photo ID such as a passport or driver's licence.
  • Supporting Documentation: An official document that links your previous and new names. This could include:
    • Marriage Certificate
    • Divorce Decree
    • Change of Name Certificate
    • Deed Poll

In some cases, if the supporting document does not clearly link your old and new names, NAB may also require a statutory declaration confirming that both names refer to the same individual.

Pro-Tip: Before you visit the branch, create a 'Name Update Checklist' for your other accounts, such as your utility providers, ATO, and employer. Updating your name with the bank first gives you the official documentation required to update other essential services, minimizing the risk of mismatched records across your financial life.

Frequently Asked Questions

Q: Why can't I update my legal name online or via the app?
Updating a legal name is a sensitive process because it changes the core identity linked to your financial assets. Banks perform this in person to ensure the person requesting the change is the authorized account holder and that the supporting government documents are authentic. This step protects you against potential identity theft. You will need to take your original documents to a branch so the staff can verify them face-to-face.

Q: What if my marriage or divorce certificate does not list my new name?
Some certificates serve as evidence of the event (marriage) but not as an official declaration of a new name. If your documentation is insufficient, you may need a Change of Name certificate issued by the Registry of Births, Deaths and Marriages. Before visiting the branch, call NAB to clarify if your specific document is accepted, or bring a secondary form of ID that already shows your new legal name to help bridge the gap.
