Suggest leagal options for below dispute
I’ve purchased a resale apartment.
Token amount was paid in July 2024 and dastavej was done on 19th August 2025. After paying token amount I got to know from seller that he has taken a working capital loan against the property. He said he will payoff so we had decided to go ahead for dastavej. I had applied for housing loan from HDFC and they said in this condition we can only disburse 80% of loan amount which they deposited in seller’s loan account. All these time he was cooperating and given me possession in October. Since then I’ve been following up with him to pay balance 20% loan so I can get the previous agreement docs from his bank but he’s been fooling me with false promises since last couple of months. I got possession but name can not be transferred in the society as his chain agreements are with his bank. Also I’m paying interest as a pre-emi to bank as only partial disbursement has been done. I need your help to understand what are my options. I’ve paid all the amount by bank transfer. Basically all white.
