agreement to sell having been expired, their family members were produced in court, who identified their signatures, however, another fact, which cannot be lost sight off is that a perusal of the alleged agreement to sell dated 11.1.1970 shows that it was a sale deed, It mentions that the vendor is owner of the property, which has been sold by him to the vendee for a total sum of 3,500/-. Even possession had been handed over and none of the LRs or relative of the vendor will have any right in the property. It could not be disputed that transfer of an immovable property worth more than 100/is required to be registered. It is not in dispute that the alleged document dated 11.1.1970, is not registered. It is a simple writing on a plain paper. It is also not disputed that till such time respondents No.1 to 3 filed a suit for injunction, the appellant never thought of filing suit for specific performance, as even in the opinion of the appellant the alleged document was not an agreement to sell but a sale deed. It was only after respondents No. 1 to 3 filed suit for injunction that the counter claim was filed by the appellant claiming relief of specific performance.
