Article 1636. Obligation secured by suretyship

(1) The obligation secured by suretyship may be present or future, absolute or conditional. Suretyship may also secure the obligation of another surety.
(2) If the suretyship was assumed before the conclusion of the contract or other juridical act from which the secured obligation arises, it takes effect from the time of conclusion of that contract or act.
(3) Suretyship is global if it secures all the debtor’s obligations towards the creditor or an obligation to pay the debit balance of an account, without specifying the source of those obligations.
