In this article, I explained what is a Ketubah. I explained that a Ketubah is a contract and a deed of ownership. I also explained that a Ketubah is a viable document, by virtue of which a woman can file a legal action against her husband during divorce. Written claims are submitted to the Rabbinic Court, which is solely authorized to deal with matters of marriage and divorce. Beyond that, there are cases where a woman can lose her right to her Ketubah. In conclusion, I would like to recommend going to a divorce lawyer regarding the Ketubah and advice on cases related to it.
