I am a salaried person earning Rs.20,000 per month. I am married and I have a six month old daughter. My wife has jewellery which is quite more than the zakat value and comes up to Rs1,20,000 which I was supposed to take on Ramazan- September 2011. But until now I am taking zakat amount every month based on my expenses. Till now I had taken only Rs 60,000 and we are a joint family. My dad has his own business and pays the Qurbani amount for a sheep.
My question is: for these years, can my father pay for the Qurbani of me and my wife, and can I give qurbani for my 6 month old daughter from my own money?
In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
It will be permissible for your father to pay for your Qurbāni and the Qurbāni of your wife. The condition is that they you and your wife have to explicitly give permission to your father to sacrifice on your behalves. It is also be permissible for you to do Qurbāni on behalf of your daughter even though Qurbāni is not wājib on her. 
And Allah Ta’āla Knows Best
