The study states that existing laws do not reflect the diversity of faiths and beliefs in contemporary society.
Ash Patel from the Nuffield Foundation, which funded the research, said it highlighted the discrepancy between outdated wedding laws and the preferences of modern society.
He said: “It makes a clear case for urgent reform to wedding law so that it better reflects the cultural and social diversity and richness of the individuals and communities that make up the population of England and Wales.”
Researchers spoke to 170 people via focus groups and interviews, of whom 82 were involved in conducting non-legally binding ceremonies and 88 had gone through such a ceremony.
Under the current law in England and Wales, a civil wedding can only be conducted in a register office or “approved premises”, such as a hotel or stately home.
There are special rules for Anglican, Jewish and Quaker weddings, but other religious weddings can only be conducted in a registered place of worship and must include words prescribed by statute.
And despite growing demand, there is no current option for a couple to have a legal wedding led by a Humanist or independent celebrant.
Now, The Law Commission is considering reforms that the authors of the report support, including removing the need for prescribed words in wedding ceremonies and allowing a wider range of locations.
Lead researcher Dr Rajnaara Akhtar said: ”Our findings suggest that reform of weddings law is not only important but also achievable and is long overdue.
“Our participants believed the Law Commission's proposals for reform would make it easier, more inclusive, and cheaper for couples to have a legal wedding that was meaningful to them.”
The news comes as the bill to increase the legal age of marriage from 16-years-old to 18-years-old has passed through the Commons and is awaiting consideration by the Lords.
Unlike most of its neighbours, Britain allows 16-year-olds to wed with parental consent.
It is hoped that the new bill will help prevent forced marriages and has been welcomed by campaigners.
“Child marriage is child abuse,” said the health secretary, Sajid Javid.
Data published by the Office of National Statistics in August 2021 revealed that marriage rates between men and women had dropped to the lowest numbers on record.
Opposite-sex marriages had fallen by 47 per cent since 1972, largely because of people delaying marriage or couples choosing to cohabit instead.
