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

Thanks for being such a cool brother in law. I couldn’t have asked for a more chill and welcoming brother in law! Thanks for all the cool tricks and treats.

I never had a brother growing up, so it’s great to have one finally. Thanks for making my life more fun than ever.

Just because we are getting older doesn’t mean we can’t have fun. Let’s party it up all night and have some fun on your birthday dear brother in law! Love ya so much.

Your birthday is a good time to remind you that even though you are my brother-in-law, I consider you a blood brother. I’ve always got your back if you need anything.

I hope your birthday is filled with all the things you enjoy and love and also the year following is filled with all the luck you deserve.

Thanks for being such a great addition to our family! I hope your birthday is fantastic and the year following it is even better. May God bless you forever and always.

You are an incredible person. I hope you have a fantastic birthday.

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!

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!

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.
