Transfer of Property Act, 1882
34. Transfer conditional on performance of act, time being specified
Where an act is to be performed by a person either as a condition to be fulfilled before an interest created on a transfer of property is enjoyed by him, or as a condition on the non-fulfillment of which the interest is to pass from him to another person, and a time is specified for the performance of the act, if such performance within the specified time is prevented by the fraud of a person who would be directly benefited by non-fulfillment of the condition, such further time shall as against him be allowed for performing the act as shall be requisite to make up for the delay caused by such fraud. But if no time is specified for the performance of the act, then, if its performance is by the fraud of a person interested in the non-fulfillment of the condition rendered impossible or indefinitely postponed, the condition shall as against him be deemed to have been fulfilled.
