It is an absolute honor to have you as a part of our family. May God bless you today and tomorrow.

I hope your birthday is as happy and fun as you are my dear brother-in-law! You are a great guy and I hope you have a wonderful birthday! May Lord bless you.

All of us at our family are very pleased to wish you a very happy birthday! May the Lord bless you and keep you.

I’m not really great at birthday wishes, but I just want to say that you are a pretty amazing brother-in-law. I hope you have a great birthday ahead.

You’re not just my brother-in-law; you’re more than that. Wishing you the best on your birthday, lovely brother.

You’re such a cool friend, and I wish you the best in your life.

Our family get-together has gotten much more entertaining since you joined the family. Thank you for existing.

Happy birthday, dear brother-in-law. I hope you have a colorful birthday!

To my beloved brother-in-law, happy birthday. I hope your life is filled with love, joy, and happiness.

I hope this upcoming year is even better than the last! May this birthday marks the beginning of the best time of your life.

Happy birthday brother-in-law. We are blessed to have you as our family member.

My dear, I guess you know that it is all downhill from here onwards?! But happy birthday all the same!

My brother has done a lot of crazy things in his life, but the moment he brought an amazing person like you into this family, all his ‘sins’ were forgiven.

Wishing my amazing sister-in-law an amazing birthday celebration. I swear I didn’t need Facebook to remind me of your birthday!

Dear sister-in-law, as you blow the candles on your birthday cake, take note of the fact that I love you more than Queen Elizabeth II loves to wear gloves.

On this day, I want to congratulate you on turning a new age and surviving another year of my brother. Keep it up!

In the world of sisters-in-law, you would certainly win a Nobel Prize because you are such an awesome individual! Have a wonderful birthday celebration.
