Accessory character of guarantee

Guarantee is void in law if it secures an obligation which is not valid, save where the nullity of obligation arises exclusively from the incapacity of the person. § 1 - In the last case, the guarantee subsists, even though the principal debtor may cause rescission of his obligation. § 2 - Such exception does not include the guarantee offered for the loan granted to the minor as explained in the respective title, covered by articles 1535 and 1536.
