Ketuba and Prenup — The Difference and How They Work Together

Two Documents, Two Systems

In Jewish Israeli marriages, two documents often come up: the ketuba and the prenuptial agreement. They sound similar — both relate to marriage and money — but they are fundamentally different.

The Ketuba — What Is It?

The ketuba is an ancient halakhic document committing the husband to pay the wife a minimum amount at divorce, originating in Jewish law thousands of years ago. In modern marriages the traditional "200 zuz" amount is purely symbolic, and the ketuba does not define division of apartments, pensions, savings, or businesses accumulated during the marriage.

The Prenup — What Is It?

A prenuptial agreement is a modern civil-legal document under Israel's Property Relations Between Spouses Law, 1973, defining in detail who owns what before, during, and after marriage — covering apartments, pensions, savings, businesses, inheritances, and protection from a partner's debts, none of which the ketuba addresses.

Do You Need Both?

Jewish couples who want full protection need both documents. The ketuba provides halakhic and religious structure; the prenup provides civil-legal protection over actual assets under the Property Relations Law, 1973 — the part the ketuba leaves entirely uncovered. If any wording conflicts, a lawyer and rabbi should review both to ensure consistency.
