3. Savings.—Except as otherwise provided herein, nothing in this Act shall be deemed—
(a) to deprive any person of any right to relief, other than specific performance, which he may have under any contract; or
(b) to affect the operation of the Indian Registration Act, 1908 (16 of 1908), on documents.
Text of the Specific Relief Act, 1963 (Act No. 47 of 1963), as amended up to the Specific Relief (Amendment) Act, 2018. Source: India Code, Government of India.
This is a saving provision. Unless the Act says otherwise, it does not take away any right to relief, other than specific performance, that a person has under a contract. So a person can still pursue other contractual remedies. The Act also does not affect how the Indian Registration Act, 1908 operates on documents. Registration rules therefore continue to apply to documents as before.
