Me and my brother are co owners of a 2BHK flat in Mumbai. We bought the flat in 2011 and paid off the complete home loan in 2016. Th flat has been loan free since then. In 2020 my brother was in need for money to start a new business with a partner. He requested me to sign documents for a loan against the flat. He assured verbally that he would pay the EMI along with his business partner. Thinds were running fine untill kid of 2024. His business partner cheated on him. He now does not pays the EMIs. Bank has declared the account as NPA. I was told about this only when the loan account was declared NPA. The amount to be paid to bank including all charges and penalties is approx. 50 Lacs. The property value today is approx. 1 Crore. Now I want to sell the flat, take 50% property value as my share and give him his 50% share from which he can repay the loan. But he is demanding additional additional 20 Lacs for signing the sale deed. This means I would get only 30 Lacs from the property sale. Kindly suggest a way to help me claim my share in the sale price.
