Explanation:
Let us understand the meaning of tenancy: It is the "possession of any property which might be land or building and get connected as tenant".
In contrast, ownership means the property belongs that person alone or in partnership.
Understanding the above terms, We can say, Jack and Jill have been a tenant and after ten years, Jill dies. So the rest of the interest in the property will definitely go to his heirs only.
It cannot be passed to Jack because Jill's interest will not be paid by other person except for Jill's heirs. Jack heirs are no way responsible or own the property of Jack.
