In case your relationship ends, and you want to cancel your partner visa sponsorship, you will have to write a letter to the authorities mentioning your full name and date of birth, transaction reference number (TRN) or file reference number (FRN) for the application, and a statement that you withdraw sponsorship from the Partner visa application. You need to email this letter to the place processing your application. Some believe that removing an online application from ImmiAccount will withdraw their case. However, this isn’t true. In writing, you must inform the authorities that you no longer want to sponsor your former partner or spouse.
