On pain of nullity of his undertaking, the natural person guarantor shall himself affix the statement that he undertakes as guarantor to pay the creditor what he is owed by the debtor in the event of the latter’s default, within the limit of an amount in principal and accessories expressed in words and figures. In the event of a discrepancy, the guarantee is valid for the sum written out in full.
If the guarantor is deprived of the benefits of discussion or division, he acknowledges in this statement that he cannot require the creditor to sue the debtor first or to divide his proceedings between the guarantors. Failing this, the guarantor retains the right to avail himself of these benefits.
A natural person who gives a mandate to another person to act as guarantor must comply with the provisions of this article.
