In that case, let us wait for others to comment on it. I too heard that name change requests are acknowledged every 6 months, but practically, it didn't work for me. Name or surname can be changed only at the time of withdrawal. I did this for my employee, and it worked; prepare an application for a name change and submit it to the PF department. Keep the acknowledged copy with the stamp for your records. At the time of withdrawal, you can attach this letter with the withdrawal forms. I did so because there was an error in the entire name, and in another case, the spelling was wrong. But I suggest in your case, do not fall into such things, else you might end up spoiling everything for the employee. The withdrawal process might take long, resulting in numerous follow-ups in the PF department. Ideally, what difference would it make if the middle name is not mentioned (not to hurt anybody's feelings) in the PF account until the amount is deposited correctly?
