law: Specific Relief Act, 1963
  12. Specific performance of part of contract
  (1) Except as otherwise hereinafter provided in this section the
  
  court shall not direct the specific performance of a part of a contract.
  (2) Where a party to a contract is unable to perform the whole
  
  of his part of it, but the part which must be left unperformed by only a small
  
  proportion to the whole in value and admits of compensation in money, the court
  
  may, at the suit of either party, direct the specific performance of so much of
  
  the contract as can be performed, and award compensation in money for the
  
  deficiency.
  (3) Where a party to a contract is unable to perform the whole
  
  of his part of it, and the part which must be left unperformed either-
  (a) forms a considerable part of the whole,
  
  though admitting of compensation in money; or
  (b) does not admit of compensation in money;
  he is not entitled to obtain a decree for specific performance;
  
  but the court may, at the suit of other party, direct the party in default to perform
  
  specifically so much of his part of the contract as he can perform, if the
  
  other party-
  (i) in a case falling under clause (a), pays
  
  or has paid the agreed consideration for the whole of the contract reduced by
  
  the consideration for the part which must be left unperformed and a case
  
  falling under clause (b), 2[pays or had paid] the consideration for the whole
  
  of the contract without any abatement; and
  (ii) in either case, relinquished all claims
  
  to the performance of the remaining part of the contract and all right to
  
  compensation, either for the deficiency or for the loss or damage sustained by
  
  him through the default of the defendant.
  (4) When apart of a contract which, taken by itself, can and
  
  ought to be specifically performed, stands on a separate and independent
  
  footing from another part of the same contract which cannot or ought not to be
  
  specifically performed, the court may direct specific performance of the former
  
  part.
  Explanation: For the purposes of this section, a party to a
  
  contract shall be deemed to be unable to perform the whole of his part of it if
  
  a portion of its subject matter existing at the date of the contract has ceased
  
  to exist at the time of its performance.
