Traditionally, brides guests and relatives are seated on the left, grooms on the right. It depends on the venue. More modern weddings allow for general seating.

If using ushers to seat guests, front seats should be filled first to prevent a scattered look.

Ushers would normally offer their right arm to female guests and guide them to their seats. The male companion follows behind

If the bride has a father and a stepfather, it is perfectly okay to have both walk her down the aisle.

This is the usual and traditional processional order. This can be modified without a doubt, but is a good basic starting point.

The groom, the best man and an other male wedding attendant enter and stand facing toward the guests.

The usher leads the grandmother(s) of the bride to be seated.

The usher leads the grandmother(s) of the groom to be seated.

The usher takes the mother of the groom to be seated.

The usher takes the mother of the bride to be seated.

The bridesmaids walk down the aisle and take their place next to the groomsmen.

The maid of honor walks down the aisle.

The ring bearer walks down the aisle, followed by the flower girl.

Wedding march begins.

The father of the bride escorts the bride down aisle.

The Introduction : The Officiant may greet the guests and introduce the couple.

Question of Intent/Declaration of Intent:  In traditional weddings, the Officiant may ask something like: Will you have this women to be your wedded wife, to have and to hold forever? Will you love her, provide for her and keep her, in sickness and in health? With the declaration of intent, the officiant would ask  "Who gives this woman to be married today?" The Bride's father replies, "I do".

Songs and/or Prayers: There may be a singer at this point who might sing for the couple, or the Officiant my lead the guests and couple in prayer.

Wedding Vows: This would be the part that goes:

"Do you ________ take ________ to have and hold from this day forward, for better, for worse, for richer, for poorer, in sickness and health, to love and to cherish from this day forward"?

Rather than being asked by the Officiant, this is often done as a statement from one to the other:

"Julie, I take you this day to have and to hold, from this day forward... etc."

There is also a great opportunity here for the couple to exchange further vows to each other, which is covered further in Chapter 18.

The Rings:  Bride and Groom place rings on each other's fingers. They also will usually further their vows: "Please take this ring as a symbol of my commitment... "

Marriage Pronounced: Officiant declares: "I hereby pronounce you husband and wife... "

Further Acts of Tradition:  lighting of candles, etc.. Possibly more prayers which would be led by The Officiant. There may be another song by the singer at this point also.

The Final Presentation:  The Officiant presents the new couple as: "Mr. and Mrs. ________" The new husband and wife...:-) 

Usually the order of the Recessional is the excact inverse of the Processional, whatever the processional was... In other words, in the example above the Recessional would be:

Music playing gently

Bride and Groom Exit

Flower Girl & Ring Bearer Exit

Maid of Honor & Best Man Exit

Bridesmaids Exit... And so on.
