Prior to 1753 and under English common law, a marriage was valid if each spouse had simply expressed to each other an unconditional consent to the union. This was a binding contract which the courts would enforce if necessary. No particular words were necessary and the marriage was legal if the male was over fourteen years of age and the female was over twelve years of age. There was no requirement for a clergyman to conduct a ceremony, for witnesses to be present or for an actual record to be made of the event.
This all changed in 1753 with the implementation of Hardwicke's Marriage Act which required all marriages to accord to canon law in a Church of England church after publication of banns or obtaining a licence. An exception was made for Jews and Quakers. Prior to 1754 marriages which did not comply with ecclesiastical law were known as irregular or clandestine marriages.
This subsequently led to a huge number of marriages being conducted in places like the Fleet Prison and Liberty of the Fleet in London as well as many recognised parish churches including:
The chapel of the Tower of London
King’s Bench prison
Holy Trinity Minories
St James' Duke’s Place
Fledborough, Nottinghamshire
Keith’s Mayfair Chapel
The Mint, Southwark
To some extent the Savoy Chapel in the Strand and the parish of Temple in Cornwall were also centres for clandestine marriages.
The Fleet registers alone contain details of around 250,000 marriages most being recorded in the officiators' notebooks. Many such officiators were those incarcerated in the prison as insolvent debtors, working to pay off their debt.
Those parties who married in the Fleet came from all over England although most marriages were between couples who came from the area we now class as the Home Counties. The majority of Fleet marriages were for honest purposes when couples simply wanted to get married quickly or at low cost. Both rich and poor alike availed themselves of this facility.
It is known that not all the Fleet registers have survived. Most were in private hands until the early 1800s when the government purchased them and ultimately transferred them to the General Register Office. The original notebooks are now held by The National Archives and can be viewed online via The Genealogist website.
Many clergymen were conducting irregular or clandestine marriages in other areas for a suitable fee. A clandestine marriage also allowed a man who had deserted his wife to remarry bigamously with no questions being asked. Such marriages were not subject to banns waiting time and were undertaken at speed.
The Marriage Duty Act 1695 put an end to many irregular marriages at parish churches by penalising clergy who married couples without proper publication of banns or licence. The cases may appear within ecclesiastical court records. In the 1740s, over half of all London marriages took place within the environs of the Fleet Prison.
