Can a Divorced Woman Remarry Without Written Divorce Papers in Islam?

No, the marriage does not remain valid merely because the husband is not providing a written divorce—what matters in Shariah is the verbal divorce.

If your husband clearly pronounced divorce even once while you were pregnant, then the divorce took effect at that time, and your waiting period (ʿiddah) lasted until the birth of the child. With the birth of the baby, the ʿiddah was completed and the marriage ended.

After that, any repeated divorces he gave (even 20 times) have no legal effect in Shariah, because the marriage had already ended.

Therefore, if this is indeed the case, you are now Islamically free and may marry another person. A verbal nikah is also valid, provided there is offer and acceptance (ijāb and qabūl), two witnesses are present, and the mahr is agreed upon.

However, as a precaution, it is better to have your full situation reviewed by a qualified scholar or a Darul Ifta to avoid any doubt in the future.
