The Inheritance of the Hermaphrodite
Question :
What is the share of the hermaphrodite in inheritance? Does he take the share of a male, or the share of a female?
Answer:
The hermaphrodite is one whose sexual identity is unclear, whether male or female. So if he dies while (the hermaphrodite is) still a minor, then he reaches maturity and he is of indeterminate sex, he will be given half the share of a male and half the share of a female, or if (he has) not (reached maturity), he will be given the share of whichever is more obvious and it will be deferred until he reaches maturity, so that hopefully, his case will become clear.
