Why did same-sex marriage become legal?

Answered by the UK Wedding Websites editorial team · Updated 2026-10-12 · For parents

Short answer

Same-sex marriage became legal because Parliament decided all couples should have equal access to marriage and the law should treat same-sex and opposite-sex couples the same.

Same-sex marriage became legal because Parliament decided that all couples should have equal access to marriage. The law was changed so that same-sex and opposite-sex couples are treated the same. This followed years of debate, public discussion and campaigning by many people who wanted equal rights.

The change means same-sex couples can marry in a register office, an approved venue or a registered religious building that chooses to host them. It also gives couples the same legal rights around property, inheritance, pensions and next of kin.

Religious organisations still decide for themselves whether to hold same-sex weddings. The law does not force a church or other faith building to do so. Some have chosen to offer it, while others have not.

If you are planning a same-sex wedding, you may want to talk to your families and friends about what this means to you. Many couples find it helpful to explain their choice of ceremony and how they want to include their communities.

For the current rules on notice, venues and ceremonies, check GOV.UK or speak to your local register office. They can tell you exactly what you need for your wedding.
