A contract of guarantee is a contract to perform the promise, of discharge the liability,of a third person in case of his default. Anything done,or any promise made,for the benefit of the principal debtor may be a sufficient consideration to the surety for giving the guarantee.In every contract of guarantee there is an implied promise by the principal debtor to indemnify the surety, and the surety is entitled to recover from the principal debtor whatever sum he has rightfully paid under the guarantee,but no sums, which he has paid wrongfully. Any guarantee,which has been obtained by means of misrepresentation made by the creditor, or with his knowledge and assent, concerning a material part of the transaction,is invalid.Any guarantee,which the creditor has obtained by means of keeping silence as to material circumstance, is also invalid.
