Dear Anjanatanay
It may happen that while becoming member of PF for the first time, that time he opted other person(s) as his nominee, once he gets married, he want to change the nominee for that he has to submit form 2 (revised). As an HR person, you may ensure that every employee has filled in form 2 and nominated his spouse and children. Any change in the family due to child birth shall also be communicated with due submission of form 2.
With Regards
