Latest Answer: Sudarshan - The question really is can you stomach the torture you go through BBMP to get the katha changed. Even after paying a bribe if you get a B katha and one day if the Court gives approval for Akrama-Sakrama and you need to pay say around 10-20 lakhs for regularization - Can you stomach the bill ? After 5 or 10 years, If you want to sell the property and the buyer says, it has B katha and illegal so the offer would be 40% down from market - So can you stomach that ? In the end, it is you who will go through hell - not the builder, BBMP or any other guys. So think about it and make your choice. Your are responsible for your health, wealth and happiness :-) All these three would be greatly affected. That's my 2 cents.
