Understanding Joint Accounts

Opening a joint account allows two or more people to share access to a single bank account, which can be useful for managing household expenses or shared savings goals. When you apply for a joint account with Westpac, both applicants must be identified and verified as individual account holders. This process ensures that both parties have legal rights to the funds and responsibility for the account's obligations.

Because these accounts involve multiple parties, the application process requires both individuals to participate. You can typically initiate the process online, but identity verification often requires that both applicants provide acceptable forms of identification, such as a passport or driver's licence. Ensuring you have your documentation prepared before starting will help prevent delays during the verification phase.

Key Application Details

Step-by-Step Guide: How to Apply

  1. Choose your account: Visit the Westpac website to select the transaction account that best suits your joint financial needs.
  2. Start the application: Select the option for a "Joint" account during the online application process.
  3. Provide personal details: Both applicants will need to enter their individual details, including full names, contact information, and current residential addresses.
  4. Complete identity verification: Follow the prompts to verify your identity. If applying online, you may need to provide details from your physical identification documents.
  5. Submit and finalize: Once all details are verified and the application is submitted, you will receive confirmation regarding the next steps for account activation.

Troubleshooting Common Issues

  • MFA and Login Issues
    Cause: Authentication may fail if one applicant's mobile number is not correctly recorded or if there is a mismatch in the details provided compared to existing bank records.
    Simple Fix: Ensure both applicants use their own registered mobile numbers for verification codes, and double-check all data entries for typos.
    Fallback: Visit a local branch with both applicants present; staff can manually verify identification if digital systems fail.
  • Browser or App Errors
    Cause: Complex multi-user application forms can stall due to outdated browser cookies or concurrent sessions trying to load on the same network.
    Simple Fix: Clear your browser’s cache and cookies, or try using an "incognito" window to ensure a clean session for the joint application.
    Fallback: If the browser continues to error, contact the bank's support team to have an application form emailed or to book a branch appointment.
  • Locked Account / ID / Access Issues
    Cause: If an applicant has an existing profile with incorrect or expired ID details on file, the system may flag the application for manual review.
    Simple Fix: Update your personal details (such as a new address or renewed driver's licence) through your individual banking profile before starting the joint application.
    Fallback: Speak with a branch representative who can update your profile information in person before you finalize the joint application.

Pro-Tip: Before starting your application, ensure both applicants have their identification documents (e.g., driver's licence or passport) within reach. In practice, having the correct document details ready on hand prevents the application from timing out while you search for information.

Frequently Asked Questions

Are both account holders liable for the debt on the account?

Yes, when you open a joint account, both parties are typically "jointly and severally liable" for any debts or overdrafts. This means that if one person spends money and the account goes into negative, the bank may hold both account holders responsible for repaying the balance. If your financial situation changes or you separate, contact the bank to discuss closing the account or converting it to an individual account to manage your liability.

Can I add a second person to my existing individual account?

Depending on the account type, you may be able to convert an existing individual account into a joint one, but this often requires both parties to visit a branch to verify their identities. Simply adding a name online is usually not possible due to strict anti-money laundering and identification laws. As a next step, call the bank or visit a branch to confirm if your specific account can be converted or if you need to open a new joint account.
