Dear Mr. Deepan Babu,
The evidence that you have indicated will only prove about the existence of a particular property, and the registration that has taken place on 13.6.2018 and the particulars of the seller and buyer.
But what is the evidence that you have to prove that the sale consideration was in reality Rs. 39 lakhs ?
In any case, you can send your written complaint through REGISTERED POST, without delay (as any delay will help the seller to hide his cash) to the following Income Tax Authorities, who have jurisdiction over Sathyamangalam.
Joint Commissioner of Income Tax, Range-II, No.15, Gitanjali Road, Erode-638001 and
Assistant Commissioner of Income Tax, Circle-2, No.15, Gitanjali Road, Erode-638001
