Wedding anniversaries are special events in a family and especially if the anniversary is of a close family member. Marriage is a special bond of love, friendship and commitment between two individuals. Every year this special date is a reminder of the moments shared and the journey embarked on so far.

While the wedding date is special for the couple, it is of equal significance and value for their close relatives. Anniversary wishes are not just words, but they are love, emotions and good wishes conveyed to the couple for a strong and everlasting bond.

Sisters are full of love and mostly pampered. When it comes to a special occasion like her anniversary, you do not want to miss an opportunity to send a special anniversary wish to her and your brother-in-law.  


  • Keep your wishes short and sweet – Anniversary wishes are special messages for the couple. So keep in mind that whatever you write should be from your heart and real. The tone of your message should be heartfelt and warm.
  •  You should address the pair as a couple – The wedding card will be read both by your sister and brother in law. So, you should ensure that your wedding wishes address both of them. If you have something special to write to your sister, you can send it later or as a separate message.
  •  Plan your wedding wish in advance – It takes time to write the perfect wish and to choose the desired words. You want your wish to convey your thoughts and that’s why it is important to plan earlier. Take some time out to write the message and re-craft if required. You can rectify any errors and make sure that you have crafted the desired message. This will also help you save time and relieve some pressure on the D-day.


  • Don’t be over enthusiastic. Wishes must be genuine.
  • Don’t go overboard with your messages.
