This is the answer to what a humanist celebrant is licensed to do, and it depends entirely on where you are standing. In Scotland humanist marriage has been legally recognised since 2005 and now accounts for over twenty per cent of all marriages, more than any single religious denomination. The Republic of Ireland recognised it in 2012; Northern Ireland in 2018 after a court challenge brought by Laura Lacole and Eunan O'Kane, reaching fifteen per cent of all marriages there by 2024 and a five-thousandth legally recognised ceremony in 2025, with a Marriage and Civil Partnership Bill to put it on a statutory footing introduced to the Assembly in March 2026. Jersey recognised it in 2018 and Guernsey in 2021. In England and Wales it is still not legally valid: couples hold the humanist ceremony and register the marriage separately, which the Law Commission recommended changing in July 2022 and which had not been legislated by the time of writing.
