Your case involves various laws under the KSA legal system, which are important to consider:
1. KSA Labor Law: Article 11 states that “Upon the termination of the work relation, the employer shall provide the worker, upon his request, free of charge, with an end of service certificate indicating the service start date, service end date, total period of service, the nature of the work he was performing and the last remuneration he received. The employer shall return any certificates, documents, etc., belonging to the worker.”
2. KSA Law of Criminal Procedure: Article 2 states “Detention and imprisonment, searches of persons and places, and the restriction and monitoring of correspondence and the like, shall be conducted in accordance with this Law.”
3. KSA Law of Criminal Procedure: Article 102 states “A detainee or his representative may submit a request for his release to the investigator or the Bureau of Investigation and Prosecution. If he decides not to release him, he must give his reasons for doing so in writing.”
4. "In accordance with the Vienna Convention on Consular Relations (1963) to which KSA is a party, One of the duties of consular officials includes "safeguarding within the limits imposed by the laws and regulations of the receiving State, the interests of the sending State and of its nationals, both individuals and bodies corporate, within the limits of his consular district" (Article 5)
Given these laws, your fiancé, as a worker in KSA, has certain protections. Firstly, she should be able to request for her release (Law of Criminal Procedure, Article 102) and her employer is required to provide evidence of her service dates and the nature of her work (KSA Labor Law, Article 11).
You could consider reaching out to the Department of Overseas Labor in the Philippines as they might help you communicate with the Saudi authorities to ensure your fiancée's rights are protected according to these laws, as well as seek consular assistance (Vienna Convention on Consular Relations). Furthermore, consider also involving reputable NGOs or charity organizations that may assist in such cases.

Also note, that the Kingdom of Saudi Arabia has specific legal processes which must be respected and followed. It is also important to remember that she has the right to legal representation.
