What Is a Beit Din? The Rabbinical Court Explained

A beit din is a rabbinical court. The Hebrew בית דין means house of judgment, and the plural is batei din. You will also see it written bet din or beth din — different transliterations of the same institution.

Most people meet the term in one context: someone tells them a beit din has to approve their conversion. This guide explains what the body actually is, who sits on it, where its authority comes from, and the question that matters most in practice — why one beit din's decisions are accepted everywhere and another's are not.

The short definition

A beit din is a court of three judges, called dayanim, that rules on questions of Jewish law. It is not a symbolic panel and not a committee. It is a court in the full sense: it hears the parties, examines evidence, deliberates, and issues a ruling that is binding within its jurisdiction.

Three is the baseline number, and it is the number you will meet. In the Temple period the system was larger — a court of twenty-three for capital cases, and the Great Sanhedrin of seventy-one in Jerusalem. What survives in practice today is the court of three.

What a beit din actually does

Conversion is only one part of the work. A functioning beit din handles several kinds of matter.

Conversion (giyur)

Approving candidates, supervising the immersion and issuing the certificate. If the whole subject is new to you, start with what giyur is.

Jewish divorce (get)

A get can only be written, delivered and recorded under the supervision of a beit din. Without one, a civil divorce has no effect in Jewish law.

Monetary and civil disputes (din Torah)

Two parties who prefer to be judged by Jewish law can bring a dispute — a contract, a partnership, a debt — before a beit din, which acts as a binding arbitration panel.

Verification of Jewish status

Confirming that a person is Jewish when the documents are incomplete: families from the former Soviet Union, communities whose records were destroyed, adoptions.

Communal questions

Kashrut supervision, annulment of vows, oversight of a local mikveh and burial society.

That range matters when you are choosing where to convert. A body whose only activity is converting people, with no divorces, no disputes and no community behind it, is not a beit din in the way the rest of the Jewish world uses the word.

Who sits on a beit din

Three dayanim. Classical law asks that they be qualified to judge — the sources speak of mumchin, men with real expertise in the relevant area of halacha, not merely observant men.

In practice today, for a conversion to be accepted outside the local community, the three have to be rabbis whose standing is recognised in the wider Orthodox world and who sit as a court regularly. Three respected men assembled for a single occasion may satisfy the letter of the requirement and still produce a certificate that nobody will honour.

Under Orthodox halacha the dayanim are men. A female candidate is attended at the mikveh by women, and the court confirms the immersion without being present in the room.

The beit din in a conversion

The court is not there to test how much you have memorised. It decides one question: whether your acceptance of the commandments is sincere, and whether the life you are already living is consistent with it.

Three acts take place under its authority.

Kabbalat mitzvot

The formal acceptance of the commandments, made in front of the three judges. This is the heart of the conversion, and it is the reason a court has to be present at all.

Brit milah or hatafat dam brit

For male candidates, circumcision — or the drawing of a single drop of blood where the candidate is already circumcised.

Tevilah

Immersion in a mikveh, confirmed by the court. What happens at the mikveh describes that stage in detail.

Because conversion is a judicial act, it follows the rules that govern judgments: it is done by day rather than at night, and not on Shabbat or a festival. That is also why it cannot be completed over a video call. The hearing itself is described question by question in a separate guide, and the standards the court applies are the same everywhere: what an Orthodox conversion requires.

Orthodox, Conservative and Reform batei din

All three movements convene batei din, and all three use the same vocabulary: three judges, acceptance, immersion. The difference is not the procedure but the standard applied to it. An Orthodox court requires acceptance of the commandments as binding halacha, and will not approve a candidate whose daily life does not already reflect that. Conservative and Reform courts apply their own movements' standards.

The practical consequence is recognition. The Israeli Chief Rabbinate does not recognise non-Orthodox conversions for marriage registration, and most Orthodox communities worldwide follow the same line. Aliyah runs on a separate legal track, governed by the Law of Return and decided by the state rather than by the Rabbinate, and the rules there have been shaped by Supreme Court rulings. That gap is why people sometimes hear that a non-Orthodox conversion counts in Israel and are then surprised at the marriage registry. Orthodox and Reform conversion compared sets out the difference in full.

What makes a beit din recognised

There is no single global registry of valid courts, which is exactly why this question causes so much damage. Recognition rests on three things: the personal standing of the three dayanim, meaning whether other rabbis accept their rulings; the court's record, meaning whether its conversions have been accepted before and by whom; and, for anyone whose plans involve Israel, whether the court appears on the Chief Rabbinate's list of batei din whose conversions it accepts from abroad. Converting in order to marry in Israel explains what the registry actually checks.

Questions worth asking before you begin

Do these three judges sit as a standing court, or were they assembled for conversions only? Have conversions from this court been accepted by the Israeli Rabbinate, and can the court name a case? Will you receive a written certificate, a teudat giyur, and can the court confirm its authenticity years later? Does the court handle divorces and disputes as well, or only conversions?

Ask at the start, not at the end. A conversion completed before a court that turns out not to be accepted is not partly valid. The person is told to do it again.

Common questions

Is a beit din a real court?

Within Jewish law, yes. In civil law it is generally treated as an arbitration panel: where both parties agree in advance to be bound by its ruling, secular courts in many countries will enforce the award.

How many judges sit on a beit din?

Three, for conversion and for almost everything else you are likely to encounter.

Can three friends form a beit din?

For some limited matters three qualified men can constitute a court. For a conversion it is a serious mistake: the certificate will not be accepted.

What is the difference between a beit din and the Rabbinate?

A beit din is a court. The Israeli Chief Rabbinate is a state institution which, among other things, decides whose rulings it will accept for marriage registration in Israel.

Will I meet the beit din more than once?

Usually yes. Most courts meet a candidate early on and again at the end, and some meet several times over the course of the process.

What language is the hearing in?

The language the candidate speaks. Hebrew is not required. Understanding what you are accepting is.

What if the beit din says no?

A refusal is almost never final. It usually means the court wants to see more time, more consistent observance, or a firmer connection to a community. The sponsoring rabbi is normally told what is missing.
