What should a Filipino woman, who recently converted to Islam, do after marrying an Arab man for one night in the Philippines, then he traveled and refrained from communicating with her, knowing that she does not have an official marriage contract and does not know his full name, and how can she be released from this contract?

If the aforementioned contract fulfills the Islamic legal conditions, then it is a valid marriage contract, and all its legal implications apply, even if it is not registered with the court. If the husband is lost and it is unknown whether he is alive or dead, then the rulings concerning the wife of a missing person apply to her. She has the right to request separation if she is harmed by his absence, such as the unavailability of financial support or her fear of falling into Zina (unlawful sexual intercourse). In this case, she can refer her matter to the nearest specialized Islamic center in her country.
