Text of the provision

Art. 2079. An extension granted to the debtor by the creditor without the consent of the guarantor extinguishes the guaranty. The mere failure on the part of the creditor to demand payment after the debt has become due does not of itself constitute any extension of time referred to herein.

What this article means

A creditor who grants the debtor an extension without the guarantor's consent extinguishes the guaranty — the guarantor was answering for the debt as it stood, not as the creditor later chose to reshape it. The article then draws a careful boundary: the creditor's mere failure to demand payment after the debt falls due is not, by itself, an extension.
