A more thorough explanation:

INHERITOR

An inheritor is a person who receives something, usually property or money, from someone who has died. They are also known as heirs.

When John's grandfather passed away, he became the inheritor of his grandfather's estate.

After her mother's death, Jane was the only inheritor of her mother's savings account.

These examples illustrate how an inheritor is someone who receives something from a deceased person. In both cases, John and Jane received something from their deceased relatives, making them the inheritors or heirs.
