A and B are two siblings and their father had a self acquired immovable property. A and B's father has died intestate and their mother expired before their father. Due to whatever reasons, A had gifted his share to B by a registered gift deed after their father's death and it has now been more than ten years since this gifting was done. B has also mutated his name in the property. Later A has realised that this was a mistake and now wants to cancel this gift deed.
Now my questions are:
1. Is this an ancestral property and is A a coparcenor?
2. Is this gift deed null and void or not?
3. If it is void how to proceed to reclaim possession? Will a declaration suit do? This is because A is already planning to file a declaration suit about his father's other properties. Can this gifted property be also included in the suit?
4. Are there any statute of limitations to cancel this gift deed?
