Under Saudi law, based on KSA's procedural rules relevant to an Execution Law (Royal Decree No. M/53 dated 13/8/1433H), specifically in articles 46 and 47:
Article 46 suggest that "the Execution Judge shall immediately pass the decisions of non-deferred compulsory execution on the debtor in case of delay of payment of a mature debt" and
Article 47 states that "the Execution Judge may, in urgent cases, pass a decision of deferred compulsory execution subject to providing an immediate execution guarantee."
Considering these articles, your situation qualifies for the urgent case category. Though you can't keep missing payments, the law does understand situations where circumstances are beyond a person's control.
However, it is important you communicate your willingness and a definite plan to pay back your loan to the lender and the authorities. As per your situation, you can approach the Execution Judge with your situation and propose your repayment plan.
In case of insolvency, under 'The Bankruptcy Law' (Royal Deco M/05 dated 28/05/1439H; Article 144) "a natural person shall have the right to apply for financial restructuring or settlement after having settled his former obligations". This means if your financial situation worsens, there are still options for you to explore.
However, you should make every effort to fulfil your loan obligations to avoid any legal implications, which could include travel bans and potential penalties under KSA law. While this might not necessarily mean jail time, it would impact your credit rating and your ability to get loans in the future.
Remember, it's always best to address these issues head-on and approach the relevant authorities with honesty and sincerity. In any case, contacting your lender to discuss your situation is a good first step. If you and your lender can come to a mutual agreement, it may prevent the case from being escalated. This information is intended to help you understand your situation and it's advisable to consult with a legal expert directly for a personalized advice.
