I had a doubt for the supplication to be given on Eid on adha.
I just wanted to know if the qurbani is mandatory on both of us? Or just the husband as he is the head of the family.

Qurbani is only wajib for a person who has performed his / her Hajj. Other than that all the quranic we do at our homes is Mustahab ( recommended). Therefore anyone can do that.
