Renewal vows may be worded in a way that is very personal to the couple and their particular relationship. Vows typically include references to the couple's life together and why they've decided to have a renewal ceremony. They can be written down and read aloud or recited from memory.
When couples decide to have a renewal ceremony, they usually write their own vows. They may write them together and come up with the exact way they want the ceremony to flow, or they may choose to each work on their own vows individually. Since vow renewals often happen after the couple has been together for a significant amount of time, there are many ways to honor their bond and reference their shared lives. Some couples talk about specific incidents or turning points in their lives that helped them to realize how much they mean to each other.
People who have children together typically spend some time talking about the children and how they've impacted their lives. Couples with large families may also choose to make space during their vow recital to have family members speak. For help with specific words or phrases that can be used in vow renewal ceremonies, wedding and bridal websites may have some useful suggestions.
