The Orthodox Jewish Prenuptial Agreement: A Complete Guide

For Orthodox Jewish couples preparing for marriage, "prenup" can mean two very different documents. The first is the halachic prenup — a short agreement, now standard across much of the Orthodox world, designed to prevent Get-refusal and the agunah problem. The second is the civil financial prenup — the agreement New York law recognizes for defining property rights, support, and inheritance. Many couples need one; many need both; nearly all benefit from understanding how the two work together. This guide walks through the halachic prenup from start to finish — what it says, how to sign it correctly in New York, how it pairs with a financial prenup, and what to do if you are already married.

What the Halachic Prenup Is — and Is Not

The standard document, the Binding Arbitration Agreement of the Beth Din of America, does exactly two things:

• It commits both spouses, in advance, to resolve any dispute over the Get before a designated Beis Din — typically the Beth Din of America — whose ruling is enforceable in civil court as an arbitration award.
• It obligates the husband to pay a fixed daily support amount — $150 per day under the standard form, indexed to inflation — from separation until the marriage ends under Jewish law. Giving the Get ends the obligation; withholding it becomes very expensive.

Just as important is what it does not do. The halachic prenup does not divide property, waive or fix maintenance, protect a business, address inheritance, or touch any of the financial questions a divorce raises. It is agunah prevention, not asset protection. For the full mechanics of how it deters Get-refusal — and why it satisfies both halacha and New York contract law — see our companion article on agunah prevention and the halachic prenup.

Why Rabbis Now Expect It

The Rabbinical Council of America resolved in 2016 that its member rabbis must require a rabbinically sanctioned prenuptial agreement, where available, at every wedding at which they officiate, and surveys of Modern Orthodox rabbis show near-universal adoption. Many mesadrei kiddushin will simply not perform a wedding without one. Customs differ in other communities — including in parts of Brooklyn, Monsey, and Kiryas Joel — so couples should raise the question with their own rav early, alongside their attorney.

Signing It Correctly in New York

The halachic prenup is a marital agreement, and New York imposes real formalities on marital agreements. Under DRL § 236(B)(3), an agreement between prospective spouses is enforceable in a matrimonial action if it is in writing, subscribed by the parties, and acknowledged or proven in the manner required to entitle a deed to be recorded. Getting this wrong is the most common — and most avoidable — way these agreements fail. In practice, we recommend:

• Sign well before the wedding. Weeks, not hours. Signing at the wedding itself invites later claims of haste or pressure and creates logistical mistakes (missing notary, wrong version, unsigned counterpart).
• Use a notary and proper acknowledgment. A witness table at a chassunah is not an acknowledgment. Deed-level acknowledgment before a notary protects the document's enforceability in a New York matrimonial action.
• Choose the right version. The standard form comes in variants — prenuptial and postnuptial, with and without provisions extending the Beis Din's authority beyond the Get. The choice has consequences; make it deliberately, with counsel.
• Keep the original safe and give a conformed copy to a trusted third party or counsel.

Pairing It with a Civil Financial Prenup

Couples with assets to protect — a business, real estate, family wealth, expected inheritances, or children from a prior marriage — should consider a full New York prenuptial agreement alongside the halachic prenup. A few drafting principles matter when the two coexist:

• Keep them consistent. The financial prenup should acknowledge the halachic prenup and avoid provisions that conflict with the daily support obligation or the Beis Din's role regarding the Get.
• Scope the arbitration clauses carefully. Decide which disputes go to the Beis Din and which stay in Supreme Court. Many couples reserve financial and custody issues for the civil courts while committing Get-related disputes to the Beis Din.
• Full disclosure and independent counsel. New York courts scrutinize financial prenups for fair disclosure and voluntariness; each party should have their own attorney. These protections strengthen both documents.
• Include a severability clause. If any provision were ever held unenforceable, the rest of the structure should survive. We explain why in our article on severability clauses in prenuptial agreements.
• New Jersey couples: the analysis differs under the Uniform Premarital Agreement Act, and cross-state couples should plan for both jurisdictions.

Already Married? The Postnup Route

Every protection described above remains available after the wedding. The Beth Din of America form has a postnuptial version with the same arbitration commitment and support mechanism, and it can be signed on its own or together with a broader postnuptial agreement addressing finances. Communities periodically organize halachic postnup signing events; we also prepare and supervise individual executions with proper New York acknowledgment.

If the Marriage Ends

When a marriage with a halachic prenup breaks down, the documents do their work quietly: the Get is almost always arranged promptly through the Beis Din process, while the civil divorce resolves property, support, and parenting. Where there is no prenup and a Get is being withheld, New York's Get Laws — DRL § 253 and the 1992 amendments to DRL § 236(B) — and the reasoning of Avitzur v. Avitzur, 58 N.Y.2d 108 (1983), still give counsel meaningful leverage. Prevention is better; it is rarely the only option.

Frequently Asked Questions

How much does an Orthodox Jewish prenup cost?

Preparing and properly executing a standalone halachic prenup is a modest, fixed-fee matter. A combined package — halachic prenup plus a full financial prenuptial agreement — falls within our standard prenup pricing, which ranges from $2,500 for straightforward agreements to $6,000+ for high-net-worth matters. Both figures are far less than the cost of litigating a withheld Get or an unprotected estate.

Does signing a halachic prenup mean we expect to divorce?

No more than a Ketubah does. It is a communal standard precisely so that no individual couple's signing implies anything about their marriage — the same logic as insurance, and the reason many rabbis now require it of everyone.

Can we sign it if our rav has concerns?

Speak with your rav first — versions and customs differ among communities, and part of our role is coordinating the legal execution with your community's practice. The document only helps if it is both halachically acceptable to you and legally enforceable.

We were married abroad / in another state. Does New York formality still matter?

If you live in New York or may divorce here, executing (or re-executing) the agreement with New York deed-level acknowledgment is prudent. We regularly address prior out-of-state executions as part of a review.
