Goddard attended Marlborough College, where he decided on a career in law. In later life he vigorously denied the frequent claims of Lord Jowitt that he had amused his school contemporaries by reciting, word for word, the form of the death sentence upon those whom he disliked. He later attended Trinity College, Oxford and graduated with an upper second-class degree in jurisprudence in 1898, and gained a Blue in athletics. He was called to the Bar by the Inner Temple in 1899.
