Does divorce take effect merely by adopting an opinion that makes it take effect for a period, then retracting it for an opinion that does not make it take effect, with prior knowledge of all opinions? And what is the guideline for not considering someone who doubts whether he divorced or not to have divorced, and is a preponderance of suspicion sufficient, or is investigation necessary? And what is the degree of doubt that is considered actual doubt? And what is the guideline for duress in marriage, and is the wife's shyness or fear considered duress?

Whoever adopted a particular opinion regarding the issuance of a divorce cannot then revert to another opinion that it did not occur in the same incident. Some scholars, however, permit such a reversion. If doubt arises concerning the occurrence of divorce, it should be disregarded, because the default is the continuation of the marriage. This doubt includes mere suspicion and delusion. The criterion for duress in marriage is the conclusion of the contract without consent and choice, due to a threat of killing or severe harm from someone capable of carrying it out. Mere shyness or fear is not considered valid duress.
