Article 579 of the Saudi Civil Transactions Law
المادة 579 من نظام المعاملات المدنية · الفرع الأول: إنشاء عقد الكفالة
Suretyship is concluded between the surety and the creditor, the creditor's silence counts as acceptance, and it does not depend on the debtor's acceptance, so it is valid without his knowledge and despite his objection.

1- تنعقد الكفالة بين الكفيل والدائن، ويعد سكوت الدائن إذا وجه إليه الإيجاب قبولًا للكفالة.
2- لا يتوقف انعقاد الكفالة على قبول المدين، وتجوز دون علمه، وتجوز أيضًا رغم معارضته.

Article 579 explained in plain English
This article identifies the two parties to the suretyship contract and how it is concluded, and contains two rules:
First: suretyship is a contract between the surety and the creditor
The parties to the contract are the surety and the creditor, which is consistent with the definition in Article 578, which makes the surety obliged to the creditor. The text provides that if the offer (the offer of suretyship) is addressed to the creditor and he is silent, his silence counts as acceptance of the suretyship. This is a notable exception, because suretyship is in the creditor's interest.
Second: the debtor is not a necessary party
- The conclusion of suretyship does not depend on the debtor's acceptance.
- Suretyship is valid without the debtor's knowledge.
- It is also valid despite his objection.
A person may volunteer to stand surety for the debt of a friend or relative without telling him, or even over his refusal, and the suretyship remains concluded.
Even so, the other conditions of suretyship remain required, including what Article 580 provides, that the surety must have full capacity.
Anyone who wants to know the effect of the debtor's knowledge or objection on the surety's rights later is advised to consult a lawyer who specializes in civil cases.
Practical example
Omar learned that his friend owed a debt to a merchant in Dammam, so he wrote to the merchant offering to stand surety for the debt without telling his friend, and the merchant stayed silent. The merchant's silence counts as acceptance, and the suretyship is concluded even though the friend did not know of it.
