Goddard built a strong reputation in commercial cases on the Western Circuit and was appointed as Recorder of Poole (a part-time Judgeship) in 1917. Goddard was appointed a King's Counsel in 1923, transferred to be Recorder of Bath in 1925, and eventually Recorder of Plymouth in 1928. He was elected a Bencher of his inns in 1929 and undertook work for the Barristers' Benevolent Association. In the general election of 1929, Goddard agreed, against his better judgement, to contest the Kensington South constituency as an unofficial Conservative candidate. The sitting Conservative MP, Sir William Davison, had been a defendant in a divorce case, and a local committee thought the newly enfranchised young women voters would refuse to support him. In the end, Goddard, running under the slogan "Purity Goddard", came last in the poll, winning only 15 per cent of the vote, and the sitting member was returned.
