Will I face any problem during NRC as my father's name is different in my document? His name is Md.Mumtaj Ansari and in my document father's name is Md Mumtaj

First of all, please note that NRC is not implemented across India.

Even if anyone's name, age etc. is wrongly recorded in any of the documents, there would be ample scope for citizens to prove their linkage with the correct person during field verification. Affidavits if submitted will be received but corrections mentioned there in would be effected only after satisfactory verification of its particulars by verifying officials.
