I am not sure he had one and if he did, he doesn't own anything. Is it common in Korea that people worry about the will 2 days after death?

@tarazkp, Sorry if my clumsy English upset you.

In Korea, children are obligated to listen to their parents' wills before their parents die.

If children do not listen to their parents's dying words , they are criticized by people.
Is Korean custom different from Australia?

By the way, did your elder brother keep his father's deathbed?
What do you mean?

Did your elder brother hear your father's will?
