What happens to the sum of money in the joint account which is in five digits when the third joint holder party passed away?
There are 3 parties in a joint account. Only the main holder is contributing, the main holder's purpose of asking the other two parties are his elder relatives who he respected to safeguard the money to prevent him from spending.
Lately, he received a reply from the bank that says his joint account has become a deceased's account and he can not deposit or withdraw anymore. When he went to the bank personally to close the joint account providing the death certificate of his beloved aunt, they said cannot close, need to go to the public trustee to settle.
Blurred, how come he cannot close his joint account, why need to involve another party (public trustee)? He has never heard of them until the bank told him.

Is anyone aware of this, been in such scenario before?
Please advise..
Appreciated very much.
