Marriage certificates in England and Wales have traditionally left space for the names and professions of just one parent: the fathers of the couple tying the knot.

That changed on Tuesday, with couples now allowed to add mothers’ names to their official marriage record. The change corrects “a historic anomaly” and is part of a larger overhaul of how marriages are registered in the two nations, the government said. Unions will also now be recorded in a single electronic registry instead of in registry books.

The changes are the biggest to the registration system since the Marriage Act came into effect in 1837, the Home Office said, and they have been in the works for several years. In 2014, David Cameron, then the prime minister, said the system did not reflect “modern Britain” and pledged to make modifications.

But the final stages of legislation to include both parents did not come before Parliament until last month, spurred by a larger bill that passed in 2019. The earlier bill included the changeover to an electronic marriage registry and the extension of the right to civil partnerships to all couples.
