Contracts II
Restatement Second of Contracts § 116
Main Purpose; Advantage to Surety
A contract that all or part of a duty of a third person to the promisee shall be satisfied is not within the Statute of Frauds as a promise to answer for the duty of another if the consideration for the promise is in fact or apparently desired by the promisor mainly for his own economic advantage, rather than in order to benefit the third person. If, however, the consideration is merely a premium for insurance, the contract is within the Statute.
