In 1973 Professor Simpson announced the discovery of a puzzling reference to the Outer Temple in a manuscript year-book account of the serjeants' call of 1425. In addition to two new serjeants from the Inner Temple and one from the Middle Temple, one new graduand (William Halle) was described as being of the Outer or Utter Temple (‘de exteriori Templo’). Simpson posed the question whether this last was merely a geographical address or the name of a hitherto unknown institution, and concluded that it was most likely to have indicated an institution. It was presumably established within the bounds of the Temple but outside the city bars, and might perhaps be the same as ‘lostel du Templebar’ mentioned in a letter of 1426. The present writer, while cautiously treating the mystery as unresolved, has been inclined until now to favour the mere-address theory. Only two other references had been found to individuals described as ‘of the Outer Temple’: one of them a John Brown (not certainly identifiable) in 1480, and the other Anthony Wood in 1535. Now, Wood was a member of the Middle Temple, where he read in 1540, and so by his time the Outer Temple can only have been an address. It is evident from the records of the Inner Temple that the place was inhabited in the early sixteenth centuries by members of both the Temple inns.
