Prozbul

A prozbul (also spelled prosbul or pruzbul) is a legal instrument in Jewish law that allows a lender to collect a debt after the sabbatical year, when debts would otherwise be cancelled. By signing a prozbul, the lender places the outstanding loans in the hands of a rabbinical court, and because debts owed to a court are not released by the sabbatical year, the lender can still collect them afterwards. The device is attributed to Hillel the Elder, who lived in the first century BCE.

The prozbul is one of the oldest documented examples of a legal mechanism designed to keep credit flowing in the face of a religious rule that, applied literally, discouraged lending. It is still used in observant communities today.

The Torah sets a seven-year agricultural cycle, the shmita. Deuteronomy 15 adds that at the end of the seventh year every creditor must release what he has lent to his neighbor. The release covered ordinary personal loans between Jews; it did not, according to later rabbinic interpretation, extend to every kind of obligation, and wages, sale price balances and certain secured debts were treated differently.

The same chapter warns lenders not to refuse a loan because the seventh year is near. The rabbinic tradition reports that people did exactly that: as the sabbatical year approached, those with money stopped lending, and the poor, who most needed credit, were left without it. The release that was meant to protect debtors was cutting them off from credit.

The Mishnah (tractate Shevi'it, chapter 10) records that Hillel instituted the prozbul when he saw that people were refraining from lending. It relies on a rule drawn from the wording of Deuteronomy: the release applies to a creditor's personal claim against a neighbor, not to debts already handed over to a court for collection. A creditor who delivers his loans to the beit din before the year ends is therefore not exercising a personal claim when the debt is collected later. The court, in effect, collects on his behalf.

The name is usually explained as coming from the Greek pros boule, "before the council", reflecting the court's role. The Mishnah preserves the core wording, in which the lender declares to the named judges that any debt owed to him may be collected whenever he wishes.

Later rabbinic authorities debated how Hillel could adjust a biblical rule. A widely held view is that, after the destruction of the First Temple and the end of the jubilee cycle, the debt release applied only by rabbinic enactment, which gave the sages room to create an exception. These questions belong to the wider body of halacha and are argued in the Talmud and its commentators.

The Talmud and later codes set several conditions:

• The prozbul must be made before the end of the sabbatical year, so lenders sign it in the final weeks of that year, before Rosh Hashanah.
• It is executed before a court of three, often represented in modern practice by three qualified witnesses or by a recognized rabbinic court, sometimes led by a dayan.
• The borrower is traditionally required to own some land, however small, to which the debt can attach; authorities developed ways to satisfy this condition, such as the lender giving the borrower a token piece of land.
• One document can cover all debts owed to the lender at that time, and many communities circulate standard forms.

Debts that come into being after the prozbul is signed are not covered, which is why the document is signed as late in the year as practical.

Observant lenders, including individuals, community loan funds and the free-loan societies known as gemach, sign a prozbul at the end of each sabbatical year so that outstanding loans remain recoverable. Rabbinic authorities, often the posek a community follows, publish guidance and forms as the year closes. The most recent sabbatical year ended in September 2022, and the next is due to run from autumn 2028 to autumn 2029.

The prozbul sits alongside other devices that reconcile Jewish law with commercial credit. The heter iska restructures a loan as a partnership investment to avoid the prohibition on ribbit (interest), drawing on the older iska partnership. Interest-free lending itself is closely linked to the ideal of tzedakah, and comparisons are often drawn with the Islamic qard hasan, a benevolent loan made without return.

Historians of law cite the prozbul as an early, explicit instance of a legislator adjusting a rule to protect its purpose. The debt release aimed to relieve the poor; enforced without the prozbul, it starved them of credit. Hillel's enactment kept the institution of the sabbatical year intact while restoring the willingness to lend, a pattern of reasoning that appears in many later attempts to reconcile religious or social limits with working credit markets.
