Jewish marriage is not an indissoluble sacrament, but rather a contract that for a number of reasons can be dissolved.
Thus the possibility of divorce, the dissolution of marriage, comes into view. The Hebrew word for divorce is gherushim; it is formalised before the rabbinical court, the bet din. Originally, as the Hebrew word reveals, divorce was conceived essentially as the repudiation of the wife by the husband; even today, the essential element is the get, the bill of divorcement, the document that sanctions the end of the union and is handed to the wife by the husband. In reality, the woman can also request this document. There are many reasons for which the Talmud justifies divorce: the inability to procreate, incompatibility of character, unseemly conduct by either party. As a guarantee for the woman, there is the ketubbah, the marriage contract.
