law: Transfer of Property Act, 1882
  37. Apportionment of benefit of obligation on severance
  When, in consequence of a transfer, property is divided and held
  
  in several shares, and thereupon the benefit of any obligation relating to the
  
  property as a whole passes from one to several owners of the property, the
  
  corresponding duty shall, in the absence of a contract, to the contrary amongst
  
  the owners, be performed in favor of each of such owners in proportion to the
  
  value of his share in the property, provided that the duty can be severed and
  
  that the severance does not substantially increase the burden of the
  
  obligation; but if the duty cannot be severed, or if the severance would
  
  substantially increase the burden of the obligation the duty shall be performed
  
  for the benefit of such one of the several owners as they shall jointly
  
  designate for that purpose:
  PROVIDED that no person on whom the burden of the obligation
  
  lies shall be answerable for failure to discharge it in the manner provided by
  
  this section, unless and until he has had reasonable notice of the severance.
  Nothing in this section applies to leases for agricultural
  
  purposes unless and until the State Government by notification in the Official
  
  Gazette so directs.
