A vow renewal, also known as a wedding vow renewal ceremony or wedding vow reaffirmation ceremony, is a ceremony in which a married couple renew or reaffirm their marriage vows. It is a celebratory ceremony during which a married couple reaffirms their commitment to each other. The ceremony usually takes the form of a ceremony similar to a marriage ceremony, in which the couple either exchanges the same vows from their wedding day or new vows they have written for the occasion. Couples may choose to have a vow renewal for various reasons, such as celebrating a significant anniversary, having passed through a difficult time in their relationship, or in order to have a religious ceremony if their original wedding had not been one. The beauty of a vow renewal is that theres no established format to follow, so couples should feel free to get creative with their plans.
