In-Law Birthday Wishes

You can't choose your in-laws but you can choose in-law birthday wishes, but selecting the best birthday greetings for your mother-in-law, father-in-law, brother-in-law, sister-in-law, son-in-law or daughter-in-law can be difficult.

To get started, choose the type of in-law birthday messages you need below.

Your birthday is not the time to be sad. You're much too wonderful a brother-in-law to feel anything less than wonderful on your birthday. Have a wonderfully special day!

Happy birthday, bro-in-law! I don't need a Facebook reminder to remember it's your birthday. You're way too special for that (your sister just called to remind me).

Very few people in my life are birthday message-worthy. A brother-in-law like you, though, is worthy of the finest birthday wishes. May you be blessed with only the finest of everything on your special day.

Wishing a gigantic HAPPY BIRTHDAY to my favorite (and only) bro-in-law and truly one of my best pals. You give all in-laws a good name.

You mean too much to me to call you my brother-in-law. I consider you my brother, my friend and my guardian angel. Today, I wish you only the best, because that's exactly what you deserve.

From Day 1, you've been like a brother to me, not a brother-in-law. And like family, we've had our ups and downs — mostly ups, though. So, it's with lots of love that I wish you "Happy Birthday."

You've always been a great brother to your sister. Now you're a great brother-in-law to me. In other words, you're a great guy — and great guys deserve the greatest of birthdays. So let's make this one great!

Show your father-in-law that you care
Father-in-law birthday wishes...

Today, your birthday wish is everybody's command, so wish for the best. Considering that you're the greatest father-in-law in the world, your birthday wishes may just come true. I hope they do!

I will have a great life blessed with joy, hope and peace...simply because I have a saint for a father-in-law. May your birthday be likewise blessed.

There's an incredibly special individual in my life — you, my dear father-in-law. You've been my mentor, my hero and my second Dad since I came into the family. Thank you and happy, happy, happy birthday!

Dear father-in-law, you have given me two of the greatest gifts ever, two men to love for a lifetime — you yourself and my darling husband. I can't thank you enough but I can start by wishing you a very, very special birthday.

Happy birthday to a wonderful father-in-law. Today, you should take a moment to think about your lifetime of accomplishments and give yourself the accolades you deserve. If you don't, I certainly will.

Thank you for going beyond the call of father-in-law duty and becoming like a second father to me. And like any father, you knew that was exactly what I needed.
Happy birthday,
Dad 2.0!
