Patel2019

My 489 family sponsor visa granted on 2017. I landed in Australia in2018 till 1 I camebebak to India to file joint divorce petition. As per rules we have to update change of circumstances to dibp. As the sponsor is my brother in law and if I will update dibp about divorce processing can this lead to my visa cancellation as after divorce I will not be a part of family members with my sponsor. I m the main applicant of 489 visa.. Can someone please guide me the possible situation?
