Do not sign any registration papers or execute any further deeds under pressure.
Keep the original March 18 agreement for ₹61 lakh, the April 28 agreement for ₹50 lakh, and the subsequent ₹45 lakh agreement. This timeline of diminishing value perfectly documents the extortion.
Have a lawyer immediately send a formal legal notice to the broker and the third-party dummy buyer. The notice should state that the subsequent agreements (₹50 lakh and ₹45 lakh) are voidable under law because your consent was obtained through coercion and undue influence (Sections 15, 16, and 19 of the Indian Contract Act, 1872). Demand the fulfillment of the original ₹61 lakh agreement.
You may file a written complaint with your local Police Station, or directly to the Superintendent of Police (SP) if the local police hesitate to act.
Under Section 13(3A) of the SARFAESI Act, you have the right to object to the bank's notice within 15 days of receiving it. File a formal written representation explaining that you are in the process of liquidating an asset to clear the loan, but have fallen victim to a documented criminal fraud/extortion, which caused the temporary delay.
Request a temporary extension (e.g., 2–3 months) to clear the dues, or ask for a One-Time Settlement (OTS) restructure based on the genuine hardship you are facing. Banks prefer getting paid over going through the long hassle of auctioning a residential house.
If the bank aggressively pushes forward with taking possession, your lawyer can move the Debts Recovery Tribunal (DRT) to get a stay order on the auction, showcasing your bona fide intent to pay and the fraud committed against you.
Under Indian law, a contract signed when a person is deprived of their free will (due to absolute distress or blackmail) is not legally binding if challenged correctly in court. You have a very strong case of "Undue Influence." Take a deep breath—the law is on your side, but you must act now to change who holds the leverage.
