Available evidence from Mamluk Egypt indicates that talaq was not the principal means of divorce. Talaq was considered to be disastrous for the woman because it deprived her of long-term protection and financial support, preventing her from remarrying, since this would cause her to lose child custody. This led to repudiation without good reason being considered socially improper. Studies of the Ottoman Levant showed that women could invalidate a declaration of talaq by stating that the husband had shown signs of "diminished rationality" when he made it, while others used a husband's unrevoked declaration of talaq to obtain divorce at a later date if they could prove that he made it.
