No need to submit any separate documents pertaining to nomination of Form 2 of EPF. You just need to fill the details your legal nominees. Yes, you may include your family members details (along with the nomination details) to ensure "either-or survival" benefit can be given to any of your family members in absence of the "registered nominee".
Hope this will help.
All the best.
The person who told you to do this kindly tell him to go to Epfo (Govt. of India) & inquire also tell him to go through "Provident Fund Act 1952" & ask him where its written to submit the ID proof.
PF department only want proof when its a withdrawal form submission Form No 19 & 10C. A cancel cheque is to be attached with this two forms to get the funds deposited to the said bank account. Even in this PF department not ask for any ID proof.
So take the suggest step & revert if you face any query.
Form 2 submission does not require any additional documents to be submitted.
However, the verification of the nominee details should be done by the company/employer as the company authorized personnel is required to sign on the form 2. Hence, you may ask for the documents to ascertain the accuracy of name/details mentioned pertaining to the nominee.
