Period of articleship and excess leave ??

1) 2-1-14 to 18-3-15 (Your present CA can certify for only that period, for which you have served under him)

2) 15 days (logic is same as above)

3) No, you didn't. Maximum leave allowed to an article is 180 days during his 3/3.5 yr of training. In your case it is 97+15=112 days. https://icai.org/new_post.H T M L?post_id=792

wait for more views on point no. 3. Consult your regional ICAI office. And please NOTE a very very important thing- don't overwrite/use whitener in form 108. Fill the form in one go. don't make any mistake. Even writing over the text to make them more clear or visible is considered as overwriting by ICAI. Use separate form in case you have made an error. Else they will reject the application and afterwards its very difficult to get completion certificate from ICAI as you will be scuttling between institute and your home for repeated times. I have made this mistake hence a caution of word for you

Thank you Rubul
