Thank you very much V.G.Rao and Bhart.
Only last month we identified this mistake(The person who was interested in purchasing this flat, found this issue and he denies to purchase this flat since he is affraid of the legal issues which might come during future reconstruction).
So far , for the past 25 years, all our property taxes , water taxes we have filed against flat number 10 only(note: in our sale deed flat number is mentioned as 14).
We discussed with the builder also to help us in correcting this issue. He denied. I am affraid to file a case sine in my view it will be time consuming and money consuming.
Other than rectification deed, is there any option to legaly correct this issue ?
Can not we mention during this resale agreement(future registration), something like (old number 14 and new number 10) ??
What kind of risks that you foresee in one person purchasing this flat?
Thankyou in advance in helping me out.
