We love shooting solemnizations, especially personalised ones where the bride and groom would recite individually. It just makes the entire ceremony a lot of intimate rather than reading after the JP. It is perfectly alright to read if you cant remember! Just hold the card lower so that we do not get that in the frame. For those of you who are not as creative, below are some suggestions I have for you (credits to the website below)

Version 1:
I, (Bride/Groom), take you (Groom/Bride), to be my (wife/husband), to have and to hold from this day forward, for better or for worse, for richer, for poorer, in sickness and in health, to love and to cherish; from this day forward until death do us part.

Version 2:
I, (name), take you, (name), to be my [opt: lawfully wedded] (husband/wife), my constant friend, my faithful partner and my love from this day forward. In the presence of our family and friends, I offer you my solemn vow to be your faithful partner in sickness and in health, in good times and in bad, and in joy as well as in sorrow. I promise to love you unconditionally, to support you in your goals, to honor and respect you, to laugh with you and cry with you, and to cherish you for as long as we both shall live.

Version 3:
I (name), take you (name) to be my (husband/wife), my partner in life and my one true love. I will cherish our union and love you more each day than I did the day before. I will trust you and respect you, laugh with you and cry with you, loving you faithfully through good times and bad, regardless of the obstacles we may face together. I give you my hand, my heart, and my love, from this day forward for as long as we both shall live.

Version 4:
I, (name), take you, (name), to be my friend, my lover, the (mother/father) of my children and my (husband/wife). I will be yours in times of plenty and in times of want, in times of sickness and in times of health, in times of joy and in times of sorrow, in times of failure and in times of triumph. I promise to cherish and respect you, to care and protect you, to comfort and encourage you, and stay with you, for all eternity.

Version 5:
I, (name), take you, (name), to be my partner, loving what I know of you, and trusting what I do not yet know. I eagerly anticipate the chance to grow together, getting to know the (man/woman) you will become, and falling in love a little more every day. I promise to love and cherish you through whatever life may bring us.
