After my divorce, my ex-husband's name is still listed as my nominee and takaful beneficiary. Should I change it?

Yes, update it straight away, because old documents can send money to someone you no longer intend. A takaful nomination made as a hibah (gift) may still be paid to your ex-husband if it is not changed. Nominees for other savings usually act as trustees, but that still gives him a role in your financial affairs. List all your accounts, such as takaful, savings, EPF (KWSP), Tabung Haji and investments, and check the nominee on each one. Consider who is most suitable now, for example an adult child or a trustworthy sibling. Also update your will (wasiat) if it names your ex-husband as executor. See nominees and faraid.
