Canceling Adoption

दत्तक ग्रहण निरस्त नहीं होता परंतु शुन्य हो सकता है यदि पहले से जैविक संतान हो तो दत्तक ग्रहण को चुनोती दे कर शुन्य घोषित करवाया जा सकता है

There is no relation between adoption and executing a will at will.

will be valid

please provide proper information

you have not mention the reason that why you want to do so.
