Similarly to Prince William and Kate Middleton's ceremony, the couple have chosen not to pledge Meghan to 'obey' Prince Harry.
Instead, they are set to pledge themselves to one another "for better, for worse, for richer, for poorer, in sickness and in health, to love and to cherish, till death us do part".
They will also use 'you' instead of 'thee' and 'though' during the ceremony.
Prince Harry will break royal tradition and wear a wedding ring, as confirmed by Kensington Palace.
They tweeted details of the rings, writing, "Ms. Markle's ring has been fashioned from a piece of Welsh Gold, gifted by Her Majesty The Queen. Prince Harry's ring will be a Platinum Band with a textured finish."
Meghan and Harry kept their relationship a secret when they began dating, before going public with their relationship and then getting engaged in November.
