Land owner denying to register after taking 90% of money

In the absence of registered sale agreement, it will be difficult to file a suit for specific performance of contract to enforce the execution of registered sale deed. Have you entered atleast with a sale agreement?; however on the basis of sale agreement, you can issue a legal notice asking to comply with the conditions of contract to enforce the sale deed by performing his part of contract to receive the balance of sale consideration amount and execute the registered sale deed in your favor. If he commits to it, you may file a suit before the civil court.  Even otherwise, you can file a suit for specific performance of contract with an alternative prayer to refund the advance amount paid to him with interest.  Consult a local lawyer and with his help proceed legally against the vendor.

Thanks Kalaiselvan for your time to read my case and replying We have sale agreement in place with Owner and his son (Gazette Officer) its been acknowledged and certified by (I think with Tahasildar/Munasub) now they are ready to pay back the money but the land price almost hiked to 60-70% We also dont want to loose the land, please advise how to proceed, can we approach Court for this ? if so what are the actions Court will take and how much time will it takes for the process Thanks for your kind Ashok

If you have a valid sale agreement, you proceed through court to enforce the sale agreement. First issue a legal notice demanding him to perform his part of contract by expressing your ready and willingness to perform your part of the contract, if he denies or is not complying with the demand, you may proceed through court of law for enforcement of sale agreement through court for specific relief and other remedies.
