You would be required to self-attest all these documents and also on these forms. For children, you need to submit the passbook copy. The company will do the rest (fill up the required remaining forms like form 5, 10 and 3A) and submit the same at the appropriate PF Office. Do not forget to mention your mobile number so that you get the message from the PF Office regarding the status of your claim. Ask for the acknowledgement copy (for the submission of these claim forms to the PF Office) from the company officials, which you should keep it with you for future reference. (all these forms can be directly downloaded from the PF website Epfo (Govt. of India)).
