On your birthday, I just wanted to say that you are the best thing that happened to my sister and I hope you have a wonderful birthday. It’s been great getting to know you over the years.

It’s been great to have you as a brother. Thanks for being so nice!

Having you as my brother-in-law is a blessing, we are all gathered here for you, this is your Big Day, and we hope that we all can make it amazing!

You are a year older, but I hope you will stay as jolly as ever. Happy birthday to you, my dear brother.

To my friend and brother, happy birthday. I wish the best for you because you’re an amazing human being.

We may not be related by blood, But you are truly loved. Happy birthday to you, my dear brother in law.

I hope that you have an amazing day today filled only with happiness, laughter and joy because there is nothing as important in life as being happy!

Sweetest birthday to you, my extended brother. I wish you all the best in life. And I hope my sister will let you party with me tonight. Kidding! Stay a good man and take care of my sister.

You are my wife’s sister’s husband but that doesn’t stop me from calling you a brother of my own.

I wish you a very happy birthday and I hope that you have a great day today, it may be raining outside, but I can tell that the sun is shining inside you!

The best wishes to my dear brother-in-law and my true friend! I feel lucky to have you in our family and wish you only the best things in life!

My dear brother-in-law, as long as you keep taking my side when I argue with your sister, you will keep receiving cool gifts on your birthday.

Sometimes, a brother-in-law can be just as good as a brother by birth. Thanks for being a great brother to me. I really hope your birthday is amazing as you are!

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.
