In order to entitle the plaintiff to the relief of specific performance the contract sought to be enforced must as a general rule have at least all the elements that make a contract enforceable at law.1 To discuss this branch of the subject in detail would require a repetition of all that has been said of the formation of simple contracts. Some illustrations of this doctrine will be all that will be attempted. It will be observed that equity requires, so to speak, a higher standard for specific performance than the law requires for enforcement by money damages.
