Records of the Inner London Juvenile Courts, 1910-1997. These court registers are the only surviving records of the juvenile courts to have been transferred to the Greater London Record Office (now London Metropolitan Archives). For a short period after 1909 two sets of registers were kept by each court, Part 1s and Part 2s. This mirrors the practice of the adult courts. Part 1s were cases arising mainly from arrests and charges by the police; Part 2s were normally cases brought by means of summonses. From the early 1920s most juvenile courts began to keep one series only containing both types of cases.

The information contained in registers includes: date of hearing, name of informant/complainant (often the police), name and age of the defendant, nature of the offence, the adjudication by the magistrate, and the latter's name.

These registers are not indexed. No other supporting papers have survived.
