Whether you've been married for a year, a decade, or half a century, a vow renewal can be a beautiful way to honor the bond you and your spouse share. What is a vow renewal, exactly? Essentially, it's exactly what it sounds like: A vow renewal is celebratory ceremony during which a married couple reaffirms their commitment to one another, either alone or in the presence of family members and friends. Vow renewals are especially popular on milestone anniversaries (10, 25, or 50 years), but there's no rule that says you have to wait to have one. If you are thinking about planning your own vow renewal ceremony, know that a joyous celebration of your marriage can be easily and confidently orchestrated with a little guidance, and you can plan one whenever the mood strikes.
