if you want to take a legal action towards company, you have a accepted copy of your resignation and Completed noc, or at least conditional relieving letter; F&F would be delay in most companies as it need so many signatures and approvals, if you think you may not get your F&F, take the papers to labor court and file a case on them.

I understand it may not be "No Dues" rather clearnce certificate where all the DH signed no dues means.......you owe nothing
Company would not pay any thing on head of F&F, until you finish clearance/nodues. Your complaint with labour department would stand void.

The No dues is different what you are thinking. During the course of your employment you might have provided with ID card, SIM card / Mobile, Laptop, data card, might have obtained advances from accounts & finance, reference books, tools etc., etc., in this context most of the companies will ask the resigned employee to obtain certification from each and every section / department confirming that there are no dues from the employee concerned so that the HR / Management can settle his account.
This is a mandatory document and in general this will be obtained on the last working day and with out submission of this the company will not provide the relieving / service certificate also but unable to understand why this particular company is asking for the same after 50 days. I suggest to discuss with the concerned HR, resolve the issue.
