law: 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.
