How to look for records of... Criminal trials in the assize courts 1559-1971

1. Why use this guide?

Use this guide for advice on how to find records of criminal trials held at the assize courts in England and Wales, to understand how they are arranged and what information you may find in them.

From 1559 assize courts tended to deal with the more serious criminal offences, although this was not always the case. If you are looking for records of a trial for any of the following crimes you may find you will need to look at assize court records:

• homicide
• theft (stolen goods were often under-valued as worth less than 12d to avoid making it a capital offence)
• highway robbery
• rape
• assault
• coining
• forgery
• witchcraft
• trespass
• vagrancy
• recusancy
• infanticide

For advice on similar records prior to 1559, see our guide on General eyres. For advice on locating records from 1972 onwards see our guide to records of Criminal courts in England and Wales from 1972.

Up to 1733 most assize records are in Latin.

2. The criminal court system in England and Wales until 1971

The criminal court system in England and Wales has always been divided into several categories of court, in a hierarchical structure, though courts themselves have changed and evolved. For most of the period covered by this guide the following hierarchy was in place:

• Petty sessions where minor offences were dealt with by mostly unpaid, non-professional judges known as Justices of the Peace (also known as magistrates)
• Quarter sessions were held four times a year and were also presided over by Justices of the Peace
• Assize courts where the more serious criminal trials tended to be heard, taking place at least twice a year and presided over by professional judges
• Court of King’s Bench was a central royal court sitting at Westminster with an overriding jurisdiction over the other lower courts – it was dissolved in 1875 and replaced by the King’s Bench Division (or Queen’s Bench Division) of the High Court of Justice

Originally the assize courts dealt predominantly with property disputes, but their remit gradually widened to include criminal cases as well as cases passed on from the central Westminster courts.

The counties in England and Wales were grouped into assize ‘circuits’ where cases were heard:

• Home, Norfolk and South-Eastern Circuits
• Midland Circuit
• Northern and North-Eastern Circuits
• Oxford Circuit
• Welsh Circuits including Chester
• Western Circuit

In 1956 the assizes and quarter sessions were replaced by Crown Courts in Liverpool and Manchester. This was extended to the rest of England and Wales in 1971.

3. The range of assize court records and the information they contain

Not all assize records have survived as the assize clerks sometimes destroyed them when they ran out of space. Earlier records are less likely to have been kept than later ones.

In terms of information about people, assize records, most commonly, give details of the accused. Typically this includes the name, occupation and place of abode of the accused, but some or all of this information can be unreliable as aliases were often used and other false details were given. The place of abode mentioned is often where the crime took place rather than where the accused lived.

3.1 Crown and gaol books (aka minute books or agenda books)

The best place to begin a search in the assize records is in the Crown and gaol books, also known as minute books or agenda books. These usually list:

• names of the accused
• charges against the accused
• plea
• verdict
• sentence

There may be a separate series of minute books for offences such as the failure of local communities to keep local roads and bridges in a good state of repair.

3.2 Indictments

These are the formal statements of the charge against the accused, usually annotated with plea, verdict and sentence.

Each indictment usually gives:

• name of the defendant together with any aliases
• his or her occupation
• a parish of residence
• the date of the alleged offence (by regnal year)
• details of the alleged offence, together with the name of the victim
• a list of prosecution witnesses

The details of the defendant should be treated with caution, especially before the late 19th century. The defendant’s occupation was normally given as ‘labourer’ and the parish of residence is invariably the parish in which the alleged offence took place. The alleged offence is defined by lengthy and formal phrases and some, especially in cases of serious misdemeanour, such as perjury or libel, are several membranes long.

Indictments were filed in large unwieldy bundles together with other related records, depending on the period and the circuit, such as those containing details of jury panels, coroners’ inquisitions, examinations and depositions, gaol calendars, trial minutes, commissions, presentments of non-criminal offences and recognizances (which give names, parishes of residence and occupation and are usually far more accurate than those given on the indictments themselves).

Until 1916, assize indictments were either handwritten or partly printed and partly written on parchment. After 1916 all indictments were prepared using standard, usually pre-printed, forms. These give the jurisdiction and venue, the name of the defendant, the plea, a summary statement of the charge or charges and particulars of the charges.

3.3 Depositions and examinations

Depositions, sometimes known as sessions papers, consist of pre-trial witness statements. However, the survival rate for these records is relatively poor and those that do survive have been heavily weeded. Only depositions in capital cases, usually murder and riot, tend to survive.

Deposition files, especially those from the mid-20th century or later, may also contain items used as trial exhibits, including:

• photographs
• maps
• appeal papers

3.4 Transcripts

Transcripts of what was actually said in court do not normally survive with the records held at The National Archives. A collection of contemporary pamphlet accounts of what was said in court during mostly celebrated trials for the period 1660-1908 is available on microfiche in the reading rooms at The National Archives.

The Old Bailey Online website provides detailed proceedings (although not complete transcripts of what was said) for trials at the London central criminal court.

3.5 Other records

Other assize records can include:

• pleadings
• statements of claim, defence and counterclaim
• draft minutes of trials
• correspondence of the assize clerks, mostly administrative
• coroners’ inquisitions
• jury lists
• financial business including fees and costs

4. How to find records

As most assize court records remain available only in their original paper or parchment form (copies are not available online), to search for them and see them you will need to visit us at our building in Kew. Alternatively, if you can establish the record series and document references within the series, you can use our record copying service to have copies sent to you for a charge. Either way, you will need to follow these steps to locate records:

Step 1: Establish when the trial took place

If you do not know the date or even the year of a trial you may find your search hits a dead end very quickly. Unless the records are available online (most are not), establishing the date of the trial is essential before you can make any progress with your search.

If you do not know when (or where) a trial took place, for trials between 1791 and 1892 you can search the Home Office criminal registers for England and Wales (HO 26 and HO 27) on Ancestry.co.uk (£) by name of the guilty party. The registers list people charged with indictable offences and provide the place of trial, verdict and sentence.

For trials that took place between 1868 and 1971, use the records of Crime, Prisons and Punishment on Findmypast.co.uk (£) to search by name for Home Office calendars (lists) of prisoners tried at assizes and quarter sessions (HO 140). The records can provide details of where and when a trial took place. Given the sensitive and personal nature of some of the material, not all of these records are available to the public.

Step 2: Establish which kind of court heard the trial

It’s not just assize courts that were used for criminal trials between 1559 and 1971. Some criminal trials were heard at lower or higher levels of the court hierarchy, at quarter and petty sessions or at the Court of King’s Bench (see section 2 and section 6). Furthermore, some cities, counties and regions have had their own separate courts at different times since 1559. The chief among them, the records of which are not covered by this guide, are as follows:

In London

Trials took place either at the Old Bailey, Guildhall (for crimes in The City) or Middlesex Sessions House. For advice on Old Bailey records see our guide to Old Bailey records; for advice on Guildhall or Middlesex Sessions records visit the London Metropolitan Archives.

In Middlesex

Trials took place at the Old Bailey or Middlesex Sessions House. For advice on Old Bailey records see our guide to Old Bailey records and for Middlesex Sessions visit the London Metropolitan Archives.

In Wales

Until 1830, cases in Wales were heard at the Court of Grand Sessions of Wales and records are held at the National Library of Wales. After 1830 Wales became part of the assizes circuit system and records are at The National Archives.

In Cheshire, Durham and Lancashire

In 1830 the palatinate of Chester (Cheshire) joined the assizes court system. Durham and Lancaster (Lancashire) merged into the assizes system in 1876. Prior to these years you will need to consult the Palatinate of Chester court records, the Palatinate of Durham court records or the Palatinate of Lancaster court records.

Step 3: Decide which type of record to look for

Usually, the best place to begin a search in the assize records is the crown and gaol books. To decide which kind of record will be most useful for your research see the information on record types in section 3.

Step 4: Identify the appropriate record series and piece number

* You can search by name and the term ‘assize’ for the calendars of Essex Assizes indictments in ASSI 35 (1558-1714) on the Essex Record Office catalogue.

** For Yorkshire there are two series of Crown & Gaol Books for the earlier period so you will need to check both.
