Yes, Im using M+, direct CDS. Actually I don't really care direct or nominee since I don't hold stocks for long (i.e generally not more than 2 years), but the low fees form M+ actually attracted me. If you want to open up an M+ account can let me know. I can ask the processing team to reach you out directly. Processing is fast and foc.

None from Bursa. If you want to safeguard the inheritance of your shares after you have passed away, you'll require a will (your shares will be part of your estate).

While waiting for others with better experience to comment, attached PDF is Bursa Malaysia's SOP on dealing with the shares of a CDS account holder in the event of death/bankruptcy.
