Tomorrow modern-thinking Miss Middleton will pledge to 'love, comfort, honour and keep' William. The vows are printed in full below.
The soon-to-be royal is following in the footsteps of the Prince's mother Diana who also opted not to 'obey' the Prince of Wales during their wedding ceremony in 1981.
The Queen, Princess Margaret and the Princess Royal all said they would obey their husbands.
William and his fiancee have selected the Series One Book of Common Prayer ceremony, from 1966, which allows the bride to drop 'obey him' and 'serve him' from the religious proceedings.

The programme also contains a hand-drawn colour map of the carriage procession route, as well as the history of the abbey and details of William and Kate's coats of arms.

Tom Bradby, ITN political editor and William's friend, told ITV's Daybreak that the couple were trying to foget so many people will be watching.
'I think there has been a really concerted attempt to block it out and just concentrate on their marriage,' he said.
'The church is going to be full of many, many people, a lot of whom they've never met, and they just want to think about themselves and what it means to them.'
Mr Bradby, a former royal correspondent, will attend the wedding as a guest.
Mr Bradby said William was determined to protect his fiancee from intrusion into their lives.
'I have really been struck over the last 10 years about how determined he has been to protect,' he said.
'He looked at his mother and what happened to her and it didn't take a genius to draw the lessons that he's obviously drawn from it - which is he doesn't want that sort of chaos in his life.
'He's tried to effectively create this iron wall around his friends and his girlfriend. You kind of worry for them that this is the moment the world gets let in.'
Mr Bradby described the young couple, who met as undergraduates at the University of St Andrews, as 'sophisticated' media operators.

William's father the Prince of Wales and stepmother the Duchess of Cornwall and Kate's parents Carole and Michael Middleton and sister Pippa will all act as witnesses and sign the historic marriage registers during the ceremony on Friday.
It also emerged that the bride will walk up the aisle to the dramatic sounds of a coronation anthem - the soaring choral masterpiece 'I was glad' by Sir Charles Hubert Hastings Parry from Psalm 122.
It was composed for the crowning of Prince William's great-great-great grandfather Edward VII at Westminster Abbey in 1902, but is also popular at weddings.
As the choir begins to sing, the bride will begin her three and a half minute procession through the Nave and Quire to meet her Prince on her father's arm.
The newlyweds will leave the Abbey to the sounds of the well-known rousing orchestral march Crown Imperial by William Walton, which was also played at Charles and Diana's wedding.
The three hymns - 'Guide me, O thou great Redeemer', 'Love divine, all loves excelling' and Jerusalem which begins 'And did those feet in ancient time' - are all favourites of the couple.

Royal bride vows to 'love, comfort, honour and keep' William
Here is the full Solemnization of Marriage conducted by the Archbishop of Canterbury from the Order of Service:
The Archbishop says to Prince William:
William Arthur Philip Louis, wilt thou have this woman to thy wedded wife, to live together according to God's law in the holy estate of matrimony? Wilt thou love her, comfort her, honour and keep her, in sickness and in health; and, forsaking all other, keep thee only unto her, so long as ye both shall live?
He answers:
I will.
The Archbishop says to Catherine:
Catherine Elizabeth, wilt thou have this man to thy wedded husband, to live together according to God's law in the holy estate of matrimony? Wilt thou love him, comfort him, honour and keep him, in sickness and in health; and, forsaking all other, keep thee only unto him, so long as ye both shall live?
She answers:
I will.
Royal fans: Enthusiasts sleep on the streets - one of them in a tent adorned with a Union Jack - outside Westminster Abbey as they guarantee themselves the best spots for tomorrow's ceremony
The Archbishop continues:
Who giveth this woman to be married to this man?
The Archbishop receives Catherine from her father's hand. Taking Catherine's right hand, Prince William says after the Archbishop:
I, William Arthur Philip Louis, take thee, Catherine Elizabeth to my wedded wife, to have and to hold from this day forward, for better, for worse: for richer, for poorer; in sickness and in health; to love and to cherish, till death us do part, according to God's holy law; and thereto I give thee my troth.
They loose hands.
Catherine, taking Prince William by his right hand, says after the Archbishop:
I, Catherine Elizabeth, take thee, William Arthur Philip Louis, to my wedded husband, to have and to hold from this day forward, for better, for worse: for richer, for poorer; in sickness and in health; to love and to cherish, till death us do part, according to God's holy law; and thereto I give thee my troth.
They loose hands.

The Archbishop blesses the ring:
Bless, O Lord, this ring, and grant that he who gives it and she who shall wear it may remain faithful to each other, and abide in thy peace and favour, and live together in love until their lives' end.
Through Jesus Christ our Lord. Amen.
Prince William takes the ring and places it upon the fourth finger of Catherine's left hand.
Prince William says after the Archbishop:
With this ring I thee wed; with my body I thee honour; and all my worldly goods with thee I share: in the name of the Father, and of the Son, and of the Holy Ghost. Amen.
The Congregation remains standing as the Couple kneels.
The Archbishop says:
Let us pray.
O eternal God, Creator and Preserver of all mankind, giver of all spiritual grace, the author of everlasting life: send thy blessing upon these thy servants, this man and this woman, whom we bless in thy name; that, living faithfully together, they may surely perform and keep the vow and covenant betwixt them made, whereof this ring given and received is a token and pledge; and may ever remain in perfect love and peace together, and live according to thy laws; through Jesus Christ our Lord.
Amen.
The Archbishop joins their right hands together and says:
Those whom God hath joined together let no man put asunder.
The Archbishop addresses the Congregation:
Forasmuch as William and Catherine have consented together in holy wedlock, and have witnessed the same before God and this company, and thereto have given and pledged their troth either to other, and have declared the same by giving and receiving of a ring, and by joining of hands; I pronounce that they be man and wife together, in the name of the Father, and of the Son, and of the Holy Ghost. Amen.
The Archbishop blesses the Couple:
God the Father, God the Son, God the Holy Ghost, bless, preserve, and keep you; the Lord mercifully with his favour look upon you; and so fill you with all spiritual benediction and grace, that ye may so live together in this life, that in the world to come ye may have life everlasting. Amen.
