Hello, 

1. As per the terms of your Agreement to sell, you can delay onlyless than a monthto get the registration done and your failure in doing so will set in motion his right to sue as you would have already informed him about obtaining the CR and title Deed.
2. In the absence of any specific clause in the Agreement that permits enhancing/ compensating the seller in case of chane in circumstances, you don't stand a chance to take a gamble.
3. Therefore, unless agreeable to the buyer, you cannot get through with refunding the whole amount and cancel the registered Agreement. As far as you have explained the terms of the agreement, the purchaser is at an advantage now to enforce the registration.

You have to honour the agreement signed by you 

2) terms of contract are sacrosanct 

3) if you fail to execute registered sale deed purchaser will file suit fir specific performance against you 

You can cancel the agreement by paying the amount to him including any damages if any

1.  Delay is caused due to circumstances out of control of seller and buyer. Even after delay buyer is ready to proceed with deal. 2.  If the seller fails to register sale deed within one month, buyer is entitled enforce the agreement and Court will enforce the agreement. Seller cannot take advantage of his default by dragging the registration beyond agree period. 3.  There is no way, the seller cannot come out of agreement.

- As per Supreme Court , all the agreements or Limitations extended for the period of the Covid-19 lockdowns 

- Hence, the one months of limitation as mentioned in the said agreement will be automatically extended limited to the lockdown periods only. 

- Further, if that buyer has delayed the registration even after the lockdown periods , then you can cancel the agreement after sending a legal notice and to refund the remaining amount as mentioned in the agreement. 

- Further, only due to increase the market price , you cannot cancel the agreement and even you cannot charge him more amount. 

The conditions of contract in the registered sale agreement deed is very clear.

Thus after obtaining the CR and the title deed the time limit is one month for execution of registered sale deed by vendor in favor of vendee.

The vendor cannot mention the escalation of price of the property to demand excess amount nor he can withdraw from his commitment made in the registered sale agreement. 

The vendor is obliged to honor the conditions of agreement if there is no fault or delay on the part of the vendee .

The vendor cannot get any relief through court of law also even if he is planning to approach court of law with his fancy idea  especially for the reason he relies upon.
