The short answer

NAB calls it a mortgage discharge authority form. You complete it online, all borrowers sign it (printed and signed, or e-signed as a PDF), and you email it to discharge.authority@nab.com.au. NAB says it needs at least 10 business days to process a discharge form, so allow that before your proposed settlement date.

Step by step

How to discharge your NAB mortgage

NAB calls it the mortgage discharge authority form.

NAB’s personal banking checklist sets out three steps. If you have a banker or broker, NAB asks you to contact them before you start.

  1. Complete the form online in one sitting. NAB says you can’t save an incomplete form and come back to it, and to allow around 10 minutes.
  2. Read and sign the document. Once all borrowers sign, NAB has your authority to discharge the mortgage. You can print and sign it, or sign the PDF with an e-signature.
  3. Email the completed, signed form to discharge.authority@nab.com.au, at least 10 business days before your proposed settlement date.

Have these ready: the borrowers, properties and home loan account numbers; any authorised representatives for the discharge (for example your solicitor or broker); the account for any refund; and the NAB transaction account to debit any fees or government charges. NAB’s page says not to use this online form if your home loan is with ubank. Business customers have a separate checklist.

Refinancing

Refinancing away from NAB?

When you refinance, your new lender pays out your NAB loan at settlement, and NAB releases its mortgage at the same time. Your new lender, or your broker, will tell you when to lodge the discharge form. NAB’s form also covers releasing a family guarantee, so check which option fits your situation.

Before you lodge, some lenders may offer to review your rate. You can compare any offer with the new loan, including the costs of switching, before you decide. See NAB home loan rates, each with its comparison rate, and how refinancing works with us.

We can help you find what your lender asks for.
