The U.S. billionaire has won a battle against 400-year-old heraldic law to show his very own coat of arms at a new golf resort in Aberdeenshire.

US property tycoon Donald Trump has fallen foul of ancient Scottish heraldic law for failing to register a coat of arms to promote a luxury golf resort he hopes to build, British media said Saturday.

His mother is Scottish, but the Trump surname is German. And that meant Trump was in violation of an ancient Scottish heraldic law dating back to 1672, which prohibits unregistered coats of arms.
