In Singapore, Muslims and non-Muslims are subjected to different sets of inheritance law. Faraid is the Islamic law on inheritance and deals with how a deceased Muslim’s assets are distributed, and is under AMLA and the Syariah Court in Singapore manages it.
How your assets will be distributed under Faraid depends on your family composition. For example, a son gets twice the share of daughter and in the absence of what’s considered a male heir (eg. son or uncle), a portion of the estate will be given to Baitulmal.
Not everything falls under Faraid. Hibah, CPF and insurance nomination, Joint Tenancy, and Deed of Family Arrangement, are some of the alternative estate planning tools suggested by Muis that you can use if you don't want to distribute through Faraid.
