How to write it

1. Thank him for something specific. Practical help, DIY, childcare — naming it beats any general compliment.
2. Skip the father-in-law jokes. They are a genre, and none of them belong in his birthday card.
3. Match your actual closeness. A polite, warm card is never wrong; overclaimed warmth reads as insincere.
4. Sign from both of you. A joint card avoids any suggestion that one of you forgot.

FAQ

What do you write in a birthday card for your father-in-law?

Thank him for something specific and wish him a good day. Specific gratitude works far better than general praise in this relationship.

Can it be funny?

Gently, if you have that kind of relationship — but avoid the standard in-law jokes entirely.

What if the relationship is difficult?

Keep it short, warm and true. A polite good wish is entirely sufficient and never reads badly.

Should I call him Dad?

Only if you already do. Using a name you never use in person makes the card feel like it came from someone else.

What is a good short message?

“Happy birthday! Wishing you a great day.”

Should the card come from both of us?

Yes, signing jointly is the norm and the safer option.
