The Ketubbah is a Jewish written marriage contract by which a man commits himself to specific obligations (including financial) towards his wife, during their marriage and in the event of divorce or widowhood. In essence, it was more of a prenuptial agreement. Not many other religions make provision for women in a marriage contract for divorce or widowhood.
Jewish exiles from Portugal and Spain illustrated the marriage contract n and elevated the art to a highly elaborate level. This tradition of decorated marriage contracts spread around the work with differing local styles and motifs.
The Ketubbah was considered legal and binding.
