Possession of the brother in fee-simple makes the sister to be heir.

Explanation

(English-origin maxim.) Where a brother dies seised in fee simple, his sister becomes his heir — seisin in the brother at death is what vests the right of inheritance in the sister.

Where this applies

• A brother dies owning a farm in fee simple, and his sister inherits because his seisin at death vests the right of descent in her.
• An only brother passes away with clear title to a house, and his sister becomes his heir by operation of law because he was seised at death.
• A man dies holding land in fee simple with no children, and his sister inherits the estate because his possession at death is what makes her the heir.
