La. Civ. Code art. 3067
Current with changes from the 2024 legislative session effective on or before 7/1/2024, from Acts 2,3, 6-535, and 580-647
A surety is not liable for a sum in excess of that expressly stated in his contract. A legal suretyship may contain terms more favorable to the creditor than those required by the law or order pursuant to which it is given, but it may not provide for a time longer than is provided by law for bringing an action against the surety.
