(a) In order for fraud to prevent the possession of property from being the foundation of prescription, such fraud must be actual or positive and
not merely constructive or legal.
(b) When actual or positive fraud
prevents or deters another party from
acting, prescription shall not run until such fraud is discovered. (Civil Code 1895, § 3597; Civil Code 1910, § 4177; Code 1933, § 85-414.)
