law: Transfer of Property Act, 1882
  51. Improvements made by bona fide holders under defective
  
  titles
  When the transferee of immovable property makes any improvement
  
  on the property, believing in good faith that he is absolutely entitled
  
  thereto, and he is subsequently evicted there from by any person having a
  
  better title, the transferee has a right to require the person causing the
  
  eviction either to have the value of the improvement estimated and paid or
  
  secured to the transferee, or to sell interest in the property to the
  
  transferee at the then market value thereof, irrespective of the value of such
  
  improvement.
  The amount to be paid or secured in respect of such improvement
  
  shall be the estimated value thereof at the time of the eviction.
  When, under the circumstances aforesaid, the transferee has
  
  planted or sown on the property crops which are growing when he is evicted
  
  there from, he is entitled to such crops and to free ingress and egress to
  
  gather and carry them.
