Hi

There's no age limit for EWS certificate. So, you don't need to be 18 years old, you need EWS certificate on your name for jee/neet and for ews reservation anywhere.

you can apply for ews  if you qualify for eligibility criteria which is

1. You should be a ‘general’ candidate (not covered under reservation for SC, ST or OBC).
2. Your family’s gross annual income should be below Rs. 8 lakhs. This includes income from all sources such as agriculture, salary, business, etc. for the financial year before you apply for the exam.
3. Your family should not own agricultural land of size 5 acres or more.
4. Your family should not own a residential flat of area 1000 square feet or more.
5. Your family should not own a residential plot (in notified municipalities) of area 100 square yards or more.
6. Your family should not own a residential plot (other than in notified municipalities) of area 200 square yards or more

Hello candidate,

Ews certificate is been made with the help of the income certificate of the earing person of your family then you can use it for yourself. So its not like you and your father have different ews certificates to be made. Hope this helps.

Thankyou!
