Agunah

Agunah (Hebrew:עגונה, plural: agunot (עגונות); literally "anchored" or "chained") is a halachic term for a Jewish woman who is "chained" to her marriage. The classic case of this is a man who has left on a journey and has not returned, or has gone into battle and is MIA. It also refers to a woman whose husband refuses, or is unable, to grant her a divorce document in Jewish religious law, known as a get.
