Refinancing a home loan in Australia surged by 18.4% in the first quarter of 2026 compared to the same period last year, according to the Australian Bureau of Statistics. With over $22.3 billion in owner-occupier loans refinanced during that quarter alone, the mortgage discharge process has become a critical step for thousands of borrowers. The mortgage discharge form is the legal document that severs your existing loan from the property title, enabling a seamless transition to a new lender. A single error on this document can trigger refinance settlement delays of up to two weeks, potentially costing you a lower interest rate lock. This guide breaks down the discharge requirements for CBA, Westpac, NAB, and ANZ, providing precise instructions on how to fill in each discharge authority correctly and what processing times to expect in 2026.
Understanding the Mortgage Discharge Process
A mortgage discharge releases the lender’s security interest over your property. When you refinance, your incoming lender must coordinate with the outgoing lender to exchange the title and funds simultaneously through the Property Exchange Australia (PEXA) electronic settlement platform. The outgoing lender cannot release the mortgage without a properly completed discharge authority form, which authorises the removal of the mortgage from the Certificate of Title. In 2026, approximately 94% of all refinance settlements now occur electronically, reducing manual processing errors but increasing the importance of accurate form submission upfront.
The discharge process involves three key stages. First, you notify your current lender of your intention to refinance by submitting the discharge form. Second, the lender calculates your discharge payout figure, which includes the outstanding loan balance, accrued interest, and any discharge fees. Third, on the settlement date, your new lender transfers the payout amount to your old lender, and the mortgage is released. Processing times vary significantly between lenders, with mortgage discharge processing time ranging from 10 to 21 business days depending on the institution and the complexity of your loan structure.
CBA Discharge Form: Step-by-Step Completion Guide
The Commonwealth Bank discharge form CBA is officially called the “Discharge Authority” and can be accessed through the CBA online portal or by contacting their mortgage discharge team directly. CBA processed over 87,000 refinance discharges in the 2025-2026 financial year, making it the most frequently encountered discharge form in Australia. The form requires your full legal name exactly as it appears on the mortgage documents, the property address, and the loan account number. You must also indicate whether you are discharging one loan or multiple loans secured against the same property.
When completing the discharge authority for CBA, pay special attention to Section 3, which asks for your nominated settlement agent or incoming lender details. This section must match the information provided in your new loan application precisely. CBA will reject any discharge form where the incoming mortgagee name does not match their records. The form must be signed by all borrowers listed on the loan. For joint borrowers who are separated, CBA requires a court order or written consent from both parties before processing the discharge. CBA’s standard mortgage discharge processing time is 15 business days from receipt of a correctly completed form, though this extends to 20 business days during peak periods in March and November.
Westpac Discharge Form: Key Requirements and Common Pitfalls
Westpac’s discharge form is integrated into their broader “Request to Discharge Mortgage” document, which also serves as the discharge authority for St.George, Bank of Melbourne, and BankSA under the Westpac Group umbrella. In 2026, Westpac introduced a digital discharge submission option through their online banking platform, reducing paper-based processing delays by approximately 40%. The form requires your BSB and account number, the property security address, and a clear indication of whether you are performing a full discharge or a partial release of security.
The most common error on the Westpac discharge authority is omitting the discharge reason code. Westpac requires borrowers to select from a predefined list: refinance to another financial institution, sale of property, or internal product switch. Selecting the incorrect code can route your application to the wrong department, adding 5 to 7 business days to the processing time. Westpac also requires that any outstanding redraw balance be formally acknowledged by the borrower in Section 4 before the discharge can proceed. If you have a fixed-rate loan, Westpac will calculate break costs at the time of discharge, and these must be paid before settlement can occur. The standard turnaround time for Westpac is 12 to 15 business days, with the digital submission option typically processing within 10 business days.
NAB Discharge Form: Documentation and Processing Timeline
The NAB discharge form NAB is formally titled the “Discharge Authority and Request to Discharge Mortgage.” NAB processed a 22% increase in refinance discharges in early 2026, driven by competitive variable rates in the post-RBA adjustment environment. The NAB discharge form differs from other lenders in that it requires two separate signatures: one authorising the discharge and a second confirming that you understand any break costs associated with fixed-rate loans. NAB will not process a discharge if there is a pending direct debit within 3 business days of the requested discharge date.
For borrowers with an offset account linked to their NAB mortgage, the discharge form must be accompanied by a separate “Offset Account Closure Request” if you wish to close the offset simultaneously. NAB’s mortgage discharge processing time is 15 to 18 business days, but this can extend to 21 business days if the loan has multiple security properties or guarantors. The form must be witnessed by an authorised person, such as a Justice of the Peace or solicitor, if the loan amount exceeds $1 million or if the borrower resides overseas. NAB’s discharge team can be contacted directly on their dedicated refinance hotline, which operates from 8am to 7pm AEST Monday to Friday.
ANZ Discharge Form: Navigating the Authority and Settlement Process
The ANZ discharge form ANZ is part of the “ANZ Discharge Authority” package, which includes a direct debit cancellation form and a credit contract discharge request. ANZ requires borrowers to complete all three components for a complete discharge application. In 2026, ANZ updated their forms to include a specific field for the PEXA workspace ID, which your incoming lender must provide before the discharge can be lodged. This integration with the electronic settlement platform has reduced settlement failures by 28% compared to the previous manual process.
When completing the ANZ discharge authority, you must list all current registered proprietors exactly as they appear on the Certificate of Title. ANZ cross-references this information with the Land Titles Office records, and any discrepancy will result in an immediate rejection. The form also requires your ANZ customer reference number, which is distinct from your loan account number and can be found on your internet banking dashboard. ANZ’s standard processing time is 15 business days, but discharges involving company borrowers or trust structures require an additional 5 business days for verification. Fixed-rate loan discharges with ANZ will attract break costs calculated on the day of settlement, and ANZ recommends requesting a payout figure within 24 hours of your expected settlement date to ensure accuracy.
How to Fill Discharge Authority Correctly: Universal Best Practices
Completing a discharge authority correctly is the single most effective way to prevent refinance settlement delay reasons from derailing your new loan. Start by downloading the correct form directly from your lender’s website or secure messaging portal. Using outdated forms from third-party websites is a primary cause of rejection, as lenders updated their forms in January 2026 to comply with new ASIC disclosure requirements. Enter all names exactly as they appear on your mortgage statement, including middle names that may have been omitted in informal correspondence.
The incoming mortgagee details section must be completed by your new lender or their solicitor. Never attempt to fill in this section yourself, as it requires specific settlement instructions that only the incoming lender can provide. Verify that the property address matches the Certificate of Title, not your postal address. For investment properties with a different mailing address, this mismatch is a frequent source of error. Sign the form using the same signature style used on your original loan application. If you signed digitally for your original loan, request a digital signing option for the discharge form as well. Finally, submit the form at least 20 business days before your intended settlement date to accommodate any corrections or additional documentation requests.
Common Refinance Settlement Delay Reasons and How to Avoid Them
Understanding refinance settlement delay reasons can save you thousands in additional interest payments at your old lender’s higher rate. The most prevalent cause of delays in 2026 is incomplete discharge forms, accounting for 34% of all settlement postponements according to industry settlement data. Missing signatures, especially from joint borrowers who are no longer in contact, can halt the discharge process entirely. Lenders cannot partially discharge a joint mortgage without all parties’ consent unless a court order is provided.
Discrepancies in loan payout figures represent the second most common delay factor. If your discharge form is processed early but settlement occurs days later, the payout figure may be insufficient to cover accrued interest and fees. Request a payout figure valid for the specific settlement date, and build a buffer of at least $500 to cover daily interest accrual. Third, credit card or personal loan defaults with the same lender can trigger an internal hold on the discharge. Lenders have the right to retain discharge proceeds to offset other outstanding debts under the banker’s right of set-off. Check your entire banking relationship with the discharging lender before initiating refinancing. Finally, title document availability can cause delays if your lender holds a physical Certificate of Title. While most titles are now electronic, older loans may still have paper titles that require physical retrieval and lodgement.
Lender-Specific Discharge Fees and Payout Figure Calculations
Each major lender charges a discharge fee that must be included in the final payout figure. CBA charges a $350 discharge fee for standard residential mortgages, plus a $250 government registration fee to remove the mortgage from the title. Westpac’s discharge fee is $350, with an additional $120 settlement attendance fee if a physical settlement is required. NAB charges $350 for the discharge processing fee, and ANZ charges $350 plus a $112 title lodgement fee. These fees are deducted from the loan balance at settlement and do not require separate payment.
The discharge payout figure includes more than just the outstanding principal balance. Accrued interest from the last repayment date to the settlement date is calculated daily. If you have made advance payments or have a redraw balance, this will reduce the payout figure. Conversely, any unpaid fees, such as annual package fees or late payment fees, will increase the amount required. Fixed-rate loan break costs can be substantial, sometimes exceeding $10,000 for large loans with significant remaining fixed terms. Request a detailed breakdown of the payout figure from your lender and verify that all components are accurate before confirming the settlement date.
FAQ
What is the typical mortgage discharge processing time for each major lender in 2026? CBA processes discharges in 15 business days, Westpac in 12 to 15 business days (10 days for digital submissions), NAB in 15 to 18 business days, and ANZ in 15 business days. These times assume correctly completed forms and no outstanding documentation. Peak periods in March and November can add 3 to 5 business days to all lenders’ processing times.
How do I fill in a discharge authority if I have a joint borrower who is uncontactable? If a joint borrower cannot be located, you must obtain a court order authorising the discharge without their consent. This process typically takes 6 to 8 weeks and requires legal representation. The lender cannot waive the joint signature requirement without a court directive, regardless of the circumstances.
Why would a refinance settlement be delayed even after the discharge form is accepted? Settlement delays after form acceptance commonly occur due to payout figure shortfalls if the settlement date shifts, unmatched settlement instructions between incoming and outgoing lenders, or internal credit holds triggered by other debts with the discharging lender. Build a 48-hour buffer between form approval and settlement to resolve last-minute issues.
Can I cancel a mortgage discharge after submitting the form? Yes, you can cancel a discharge by submitting a written cancellation request before the settlement date. However, if the discharge has already been registered electronically in PEXA, cancellation may incur a $150 to $300 administrative fee depending on the lender. Contact your lender’s discharge team immediately if you change your mind.
