If u not the only child then there might be an issue.
Which post are you referring to?
In my case, definitely my only child will have a very trying time, with or without a will. I see no need for a will as I am fine with the intestate succession act.
I have bank accounts in my sole name and a 2 joint bank accounts with my child. I also have a joint account with a third party. Not only that, I have a joint bank account with my father who died 4 years ago and the bank account is still not closed. I also have 3 existing estate bank accounts in the estate of a, b and c. In addition, I have 2 bank accounts in Malaysia in my sole name. Balances in the accounts are not much, but they are still money
Then I also have shares under CDP in my sole name and another CDP in joint names with my deceased father and shares under CPFIS

Some, not all, shares under my CDP are mutually held on behalf of third party on shared basis and some belong to third party and some delisted/suspended. The third party also have some shares under CDP on in the same manner i.e. belong to me and some on shared basis. Besides I have shares in a inactive private limited company with some bank balance.
There is also an almost empty safe box with CISCO in my name and a deceased person.
The above are some of issues/assets excluding liabilities and contingencies. I have made CPF nomination but my siblings will not be happy with it, though my child is non-chalant when told about it as the bulk of it will go to my child. My fully paid up flat is in my sole name and no issue is expected.
My only child will surely face many many issues which may be contested legally and I am trying to regularise and simplify the idiosyncrasies though it will take some time. In the meantime, I have a huge worksheet listing all the assets (and wishes) and the manner in which they are held and which would require LOA and another worksheet listing all my passwords, including account numbers/contact and ATM pins. Those who owe money to me, god bless them as there is no record. My singpass will be frozen the day I uplorry just like my father's singpass when I tried to use it the next day.
What a mess I got into over the years
