Hi Krishna.. I had also received a letter from the ICAI saying that I need to make the required changes in the original deed of articles as I had registered my extension even before any letter from the ICAI.
I spoke to a person in Kanpur as my regn no. is CRO.. So they said that I am not required to send orginal deed of articles as there has been no break in my articleship period. In your case, there is a break and you have to re-execute form 102 & 103 as I wrote earlier. Please re-confirm about the req. of Form 107 because as per my knowledge it is compulsory for any extension.
