Citibank Mortgage Discharge Authority: Form and Steps

A Citibank discharge now starts with NAB’s mortgage discharge route for a home loan transferred to NAB branding. Match the current account to the client’s statement before collecting signatures, then arrange the payout and security release through the team handling that account.

Read the Brand and Credit Provider on the Statement

Read the latest statement alongside the credit contract and any transfer notice to identify the current account and credit provider. An old Citi logo on the original contract doesn’t establish the current servicing route.

Citi’s transfer notice, available as at October 2026, says Citi-branded home loans transferred to NAB-branded home loans on 24 February 2024. National Australia Bank (NAB) became the provider of Citi’s Australian consumer products on 1 June 2022.

For a loan now shown under NAB branding, use the NAB mortgage discharge guide. Keep the old Citi account details with the transfer notice so the current account can be matched correctly. If the records conflict, give NAB broker support both account references and ask it to identify the account before lodging.

Find the Current Security Release Request

Start with NAB’s mortgage discharge page to select the request for the current account. As at October 2026, its personal banking route leads to the online Letter of Instruction – Mortgage Discharge. Its business banking route supplies a separate mortgage and business security authority.

A saved Citi Security Release Request is a historical document. Use the authority for the current NAB account instead of uploading that saved copy through an old Citi destination.

1. Match the current loan number and property address to the statement.
2. Select the personal or business banking route that applies to that account.
3. Record the form title and completion or download date. For a PDF, also retain its printed version code.
4. Complete the requested borrower and property-owner details. Add the settlement representative’s details and the account instructions.
5. Obtain all signatures required by the current authority. Match each borrower’s and property owner’s name and signing capacity to the loan records.
6. Complete and sign the personal form or business authority, then email it to discharge.authority@nab.com.au. NAB’s personal discharge checklist gives this email destination for the personal form. For the business authority, include the contract of sale for a property sale.
7. Retain the completed authority and submission receipt with the file.

As at October 2026, NAB’s business discharge checklist permits electronic or wet signatures and gives that email destination. It requires at least 10 business days to process the request.

The NAB personal form must be completed in one session, as at October 2026. Have all account details ready before starting because an incomplete form cannot be saved for later.

Full Payout, Partial Release and Signatures

A full payout repays the loan and releases its security, while a partial release removes one security and leaves a loan running. Identify every account being closed or reduced and every property being released. A partial release can require a new assessment or valuation because the lender must assess the debt against the security that remains.

For example, selling one of two secured properties while keeping the loan is a partial release. Record the proposed repayment from the sale and the property staying as security. Obtain the lender’s approval of that continuing arrangement before treating the release as ready for settlement.

Collect authorisation from every borrower and mortgagor required by the issued authority. A mortgagor is the property owner who gives the lender security, and can be different from the borrower.

For NAB’s business authority, as at October 2026, property or security owners must authorise the release. For a loan closure, borrowers who aren’t those owners also sign the borrower section. Its July 2024 form includes individual and company-signatory fields and authorisation where the borrower is a trust.

For a company, identify the authorised company signatories. For a trust, match the trustee’s legal name and signing capacity to the loan records. Where an attorney signs, arrange the lender’s acceptance of the power of attorney and signing format before submission.

Processing Time and the Payout Figure

Allow at least 10 business days for NAB to process the discharge request, according to its instructions as at October 2026. Work backwards from the proposed settlement date, excluding weekends and applicable public holidays. Lodge earlier where signatures, an entity authority or a partial-release approval must also be resolved.

Treat that calculation as the latest planning deadline, not confirmation that settlement is booked. Obtain acknowledgement of the completed authority and resolve missing information before relying on the proposed date. NAB’s broker, solicitor and conveyancer support number is 1300 622 276, as at October 2026.

Have the settlement representative obtain the payout figure for the agreed settlement date before funds are finalised. The figure must cover the accounts being paid out, interest to that date and applicable charges. If settlement moves, obtain an updated figure because interest and intervening transactions can change the amount due.

Use the current team’s payout arrangements for the NAB account. Historical Citi form timing doesn’t set the timetable for that transferred account. Keep an indicative balance separate from the settlement payout figure.

For a fixed-rate loan, allow for any applicable early repayment cost in the payout. Use the break costs guide for the calculation process. Record the actual discharge and registration charges from the applicable loan terms or settlement statement instead of applying an old Citi fee to the transferred loan.

Confirm Release and Close Linked Accounts

Confirm both settlement completion and mortgage removal from the title with the conveyancer or solicitor. A repaid loan balance alone doesn’t establish that registration has finished. Retain the settlement confirmation and evidence of the completed title change.

Check linked offset and transaction accounts separately. Record whether each account must stay open or close, where surplus funds go and which account funds a shortfall. Move direct debits and incoming payments before closing an account the client still uses.

If the authority is returned, correct the stated account, signature or capacity error before resubmitting. If settlement finishes but the mortgage remains on the title, ask the conveyancer to trace lodgement and registration through the settlement participants.

Use the mortgage discharge process guide for settlement and registration roles, or the lender discharge directory for another lender on the title. Close the file when the intended security is released and every continuing or closing account matches the client’s instructions.
