Hi, My wife is working in mnc company, prioir to her marriage she was working in NIIT Smart Serve at trainee in 2003-4. her surname has got changed, through i have read discussion under same topic that marriage certificate along with bank account details with new name need to be submitted, but we have not applied for marriage certificate and her passport, voter id card, aadhar card has my name mentioned in the spouse column. We have passport of her son where both of us details are mentioned. Kindly let me know any other proof can be submitted in place of marriage certificate for withdrawl of PF in maiden name,

Dear Alok,
