Divorce in England and Wales is allowed on the ground that the marriage has irretrievably broken down. The Matrimonial Causes Act 1973 specifies that the marriage may be found to have irretrievably broken down if one of the following is established:
Civil remarriage is allowed. Religions and denominations differ on whether they permit religious remarriage.
A divorce in England and Wales is only possible for marriages of more than one year and when the marriage has irretrievably broken down. Whilst it is possible to defend a divorce, the vast majority proceed on an undefended basis. A decree of divorce is initially granted 'nisi', i.e. (unless cause is later shown), before it is made 'absolute'.
Prior to the Matrimonial Causes Act 1857, divorce was governed by the ecclesiastical Court of Arches and the canon law of the Church of England. As such, it was not administered by the barristers who practised in the common law courts but by the "advocates" and "proctors" who practised civil law from Doctors' Commons, adding to the obscurity of the proceedings. Divorce was de facto restricted to the very wealthy as it demanded either a complex annulment process or a private bill leading to an act of parliament, with great costs for either. The latter entailed sometimes lengthy debates about a couple's intimate marital relationship in public in the House of Commons.
The Matrimonial Causes Act 1937 made divorce easier to access, particularly for women, who until then could not get a divorce merely on grounds of adultery, as men could: women needed to show more causes than adultery, such as incest, sodomy, or cruelty. The need for the reforms was illustrated in the best-selling satirical novel Holy Deadlock (1934).
