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

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.

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

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.
