British parliament accepts registration of births, marriages and deaths.

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body of the United Kingdom, and may also legislate for the Crown Dependencies and the British Overseas Territories. It meets at the Palace of Westminster in London. Parliament possesses legislative supremacy and thereby holds ultimate power over all other political bodies in the United Kingdom and the Overseas Territories. While Parliament is bicameral, it has three parts: the sovereign, the House of Lords, and the House of Commons. The three parts acting together to legislate may be described as the King-in-Parliament. The Crown normally acts on the advice of the prime minister, and the powers of the House of Lords are limited to only delaying legislation.

The Marriage Act 1836, also known as the Act for Marriages in England 1836 or the Broomstick Marriage Act, was an act of the Parliament of the United Kingdom that legalised civil marriage in what is now England and Wales from 30 June 1837.
