Need suggestion to buy the plot or not

Dont buy this property as the GPA is null & void in the eyes and all the rights of the property is inherited by the Class 1 heirs of the deceased original owner.

you can take action to recover your money even till 3years from the date of expiry of your agreement by filing Suit for Recovery, do file a police complaint as well for fraud committed by the GPA holder

I partially appreciate the advice of Mr Chabra,

In this case you have not mentioned any where that in who's physical possession is the property, as the physical possession is a must in case of any sale deed. As with out the transfer of the physical possession there is no sale complete.

In case the GPA holder gets sale deed done in the favour of his wife and his wife takes possession of the property in her hand you are advised to stay calm for at least a year and only than after go for a sale deed with her, meanwhile you get prepare a new agreement with the party that in case the subject property will be registered in the name of the wife of GPA holder you are ready to get it purchased the same property after a year on such an such amount and for which you already have given you as an advance of Rs 4 Lac to his wife as a real owner of the property.

Otherwise you are not advised to purchase the property in any circumstances as limitation required for getting cancel the fraudulent  deed of sale is three years from the date of its knowledge. 

The GPA deed is invalid and infructuous as on date because the principal has died. Therefore the sale deed proposed to be made in favor of the wife of the GPA holder now will also be invalid in the eyes of law.  If the class I legal heirs file a case claiming the property,the same will be ordered to return to them.  Better shed away the deal and take back the money.  If he is refusing to return, you may issue a legal notice to the GPA holder stating that since his principal has already died the holder is not having power anymore to proceed with the execution of sale deed on behalf of the dead person hence instruct him to refund the advance amount subsequent to which you may file a money recovery suit.

My agreement with owner is getting finished in 3 days, since last week he is saying that he will return the paid advance of 4 Lakhs. Till now I haven’t received the advance.

My concern do I need to file a Suit for Recovery & police complaint before my agreement expires. Does the agreement valid after the expired date of 3 Months?

Earlier it was mentioned by nitesh chhabra that I have 3years from the date of expiry of the agreement by filing Suit for Recovery. One of my friend said the legal action has to be taken before the agreement expires.
