I want to discontinue my practice, but i have not received my original Certificate of Practice. Please guide me how to proceed further as i read on icai website that i need to surrender my original COP.
It seems a bit strange that you were practicing without collecting original COP. But requirement is requirement. So I would suggest you to visit your nearest ICAI branch and ask them to provide original copy of COP.
Or alternatively they can suggest you if you can surrender COP on the basis of COP number.
