Bromley is variously stated to have been Reader at the Inner temple in 1566 for Lent, and autumn although the Inn's records only mention his selection as attendant on the Lent Reader, Francis Gawdy. ODNB states that he served in the autumn and lectured on the Statutes of Attaints. He is listed as a double reader, along with his brother George, in a state paper, probably from about 1579. In 1567 the parliament of the Inn had to rectify a number of anomalies relating to chambers held by Onslow, Bromley and Gawdy, making clear that Bromley had been admitting trainee lawyers of his own for some years, even before he became a bencher. On 25 October 1573 Bromley was chosen to be Lent Reader for the following year but the honour was deferred until 1575 because of the pressure of parliamentary business, with Edmund Anderson standing in for him.
