The lawful heir is he whom the marriage shows to be so.

Explanation

Inheritance follows lawful marriage — at common law, only those born within wedlock possess inheritable blood.

Where this applies

• A child claims inheritance and the question is whether they are the lawful heir.
• Someone born in wedlock asserts their right to inherit.
