Right of Set-Off in Israel: Cancelling Mutual Debts Under Israeli Contract Law

Imagine you are a foreign company that supplied software services to an Israeli technology firm. The Israeli firm owes you NIS 300,000 in unpaid invoices. At the same time, you owe the Israeli firm NIS 120,000 in unused advance payments under a separate support contract that was cancelled. Rather than paying the NIS 120,000 and then suing for the NIS 300,000, Israeli law offers a more direct route: exercise the right of set-off, extinguish the NIS 120,000 by notice, and demand only the net NIS 180,000 that remains.

This mechanism, the right of set-off (זכות הקיזוז in Hebrew), appears in many commercial and consumer situations in Israel. Foreign creditors, importers, real estate investors, and business partners operating across borders frequently find themselves holding both a payable and a receivable with the same Israeli counterparty. Understanding when set-off applies, what notice is required, and what limits exist can determine whether a dispute is resolved efficiently or escalates into expensive litigation.

1. What Is the Right of Set-Off Under Israeli Law?

The right of set-off is the mechanism by which a party who both owes and is owed a monetary obligation by the same counterparty can extinguish one debt against the other without going to court. The result is that both debts are cancelled to the extent of the smaller one, and only the net difference (if any) remains owing.

The core provision is Section 53 of the Contract Law (General Part) 5733-1973 (chok haChozim, Chelk Klali). It states that where a party has a monetary obligation toward another party, and that other party has a monetary obligation toward the first, either party may set off the obligation owed to it against the obligation owed by it, by giving notice. After notice is given, to the extent of the set-off, both obligations are extinguished.

A few things are worth noting about how this works:

• Unilateral action: The party exercising set-off does not need the other party's agreement. Valid notice is sufficient; the legal effect is automatic.
• No court order required: Set-off under Section 53 is extrajudicial. The court's role is only to verify, after the fact, whether the conditions for a valid set-off existed when notice was given.
• Mutual extinction: Once a valid set-off is exercised, both obligations are legally extinguished (up to the amount of the smaller debt). They do not merely suspend; they disappear.
• Currency alignment: Israeli courts generally require that both debts be in the same currency, or that one be converted at the prevailing exchange rate on the date of the set-off notice, before the netting can be computed.

2. The Four Requirements for a Valid Set-Off

Not every pair of mutual obligations qualifies for set-off under Israeli law. The following conditions must all be satisfied at the time the set-off notice is given:

1. Both Obligations Must Be Monetary

Set-off under Section 53 applies only to monetary obligations — debts expressed in a sum of money. You cannot set off a money debt against an obligation to deliver goods, provide services, or perform a specific act. If the cross-obligation is not monetary, it cannot be set off; the party may still file a counterclaim for damages, but that is a different remedy.

2. The Obligation to Be Set Off Must Be Due and Payable

The debt the exercising party wants to offset must have matured: it must be legally due for payment. Future obligations, contingent debts, or amounts whose payment date has not yet arrived cannot be set off under Section 53. This is a common trap: a party who wants to set off a debt that falls due in three months cannot do so today; they must wait until the payment date arrives.

3. The Amount Must Be Capable of Determination

The set-off works only if the amount of the cross-obligation is liquidated — either fixed or capable of being calculated without further adjudication. A claim for unliquidated damages (for example, a pending claim for consequential losses whose amount has not been assessed) cannot be set off unless the parties agree on the amount or a court has already quantified it.

Partial set-off is permissible. If you owe NIS 500,000 and are owed NIS 180,000 that is liquidated, you can set off the NIS 180,000 and the remaining NIS 320,000 stays outstanding. You do not need to wait until all cross-claims are quantified before exercising set-off on the ones that are already liquidated.

4. No Defense Available Against the Set-Off Claim

The obligation to be set off must not itself be subject to a defense that would prevent its enforcement. For example, if the cross-debt is barred by the statute of limitations, it cannot be set off. Similarly, if the cross-debt arose from an illegal transaction or was already extinguished by payment, it cannot be used to exercise set-off. The party asserting set-off is effectively saying "I owe you X, but you owe me Y and I am offsetting Y against X." That Y must itself be a valid, enforceable, unextinguished obligation.

3. How to Exercise the Right: Giving Notice

Section 53 requires that the exercising party give notice to the other party. The law does not prescribe a specific form for the notice, but Israeli legal practice treats this requirement seriously. To make the set-off effective and provable in any subsequent dispute:

• Written notice: Send a written set-off notice — by registered mail, email with read receipt, or through a licensed Israeli lawyer. Verbal set-off, while theoretically possible, is difficult to prove and should never be relied upon for significant sums.
• Identify both obligations: The notice should clearly state (a) the amount and nature of the debt you owe, (b) the amount and nature of the cross-debt owed to you, and (c) the fact that you are setting off one against the other, up to the lower amount.
• State the net result: Indicate the net balance remaining after the set-off, if any. This prevents any ambiguity about what is still outstanding after the notice.
• Date the notice: The date of the notice is legally significant, because it fixes the moment from which both obligations are extinguished. Interest and CPI linkage on the extinguished portion stop accruing as of that date.

The set-off takes effect at the moment the notice is received by the other party, not when it is sent. For notices sent by email or registered mail to an Israeli address, the practical assumption is that receipt occurs within two to three business days of sending.

Once a valid set-off notice has been given, the exercising party does not need to pay the extinguished portion of its debt. If the other party sues for the full original debt, the set-off notice (and the existence of the cross-debt at the time of the notice) is a complete defense to the extent of the set-off amount.

4. Contractual Modification and Waiver of Set-Off Rights

Section 53 of the Contract Law is a default rule, not a mandatory one. Parties to a contract may agree to modify or exclude set-off rights. This is common in certain commercial contexts:

• Bank loan agreements: Banks routinely include provisions stating that the borrower may not set off any claim against amounts owed to the bank under the loan. This prevents a borrower from withholding loan repayments on the grounds of a disputed service issue with the same bank.
• Construction contracts: Contractors and sub-contractors sometimes agree that payment obligations under the contract are independent of any cross-claims, so that work proceeds and payment flows without interruption pending resolution of disputes.
• International sale of goods: Some cross-border supply agreements specify that payment is unconditional and cannot be set off against other amounts, particularly where letters of credit or bank guarantees are involved.

If a contract contains a waiver or exclusion of set-off rights, the waiver is generally enforceable under Israeli law, provided it is clear and unambiguous. Courts will not lightly imply a waiver of set-off; the contractual language must be explicit. Where a contract is silent on set-off, Section 53 applies by default.

Israeli consumer protection law adds one important limit: in contracts with consumers (tzarchanim — defined broadly to include individuals who contract outside their business or professional capacity), terms that exclude the consumer's right to raise defenses or set-offs against a creditor may be treated as oppressive standard-form terms under the Standard Contracts Law 5743-1982. Such terms may be void even if they were signed by the consumer. This is relevant for foreigners who take personal loans, buy goods on credit, or sign residential leases in Israel.

5. Set-Off as a Defense in Israeli Court Proceedings

Set-off has both an extrajudicial dimension (exercised by notice under Section 53 before or during litigation) and a procedural dimension (raised as a defense within court proceedings).

Under the Civil Procedure Regulations 5744-1984, a defendant who is sued for a money debt may raise an existing set-off as a full or partial defense in the pleadings. The court will then assess whether a valid set-off existed and, if so, reduce the plaintiff's judgment or dismiss the claim to the extent of the set-off.

Raising set-off in court does not require that the set-off notice was given before the lawsuit was filed. A defendant can exercise set-off for the first time in the defense pleadings. However, courts do look at whether the conditions for set-off existed at the relevant time, and a defendant who sat on a known cross-claim and raised it only as a litigation tactic may face costs consequences.

There is an important procedural distinction here: defensive set-off (offsetting within the existing lawsuit to reduce the plaintiff's claim) is different from a counterclaim (a separate affirmative claim brought alongside the defense). Defensive set-off is capped at the amount of the plaintiff's claim; it can reduce the judgment to zero but cannot produce a net judgment in the defendant's favor. A counterclaim is necessary where the defendant wants a positive judgment in excess of the plaintiff's claim. Many defendants raise both a set-off defense and a counterclaim in the same pleadings.

6. Set-Off in Insolvency: Broader Rights and Different Rules

When an Israeli party enters insolvency proceedings (whether individual rehabilitation or corporate liquidation), the ordinary rules of set-off are supplemented by a separate insolvency set-off regime under the Insolvency and Economic Rehabilitation Law 5778-2018 (which replaced the older Bankruptcy Ordinance and Companies Ordinance insolvency provisions).

Insolvency set-off is broader than general contractual set-off in one important way: it can apply even where the cross-obligation was not yet due and payable at the time the insolvency proceedings commenced. The rationale is that an unsecured creditor who also owes money to the insolvent estate should not be forced to pay the estate in full while receiving only a fraction of their own claim along with other unsecured creditors. By allowing insolvency set-off, the law effectively gives that creditor priority over unsecured creditors to the extent of the mutual obligation.

Under the 2018 Law, insolvency set-off differs from general set-off in several concrete ways:

• Automatic operation: Insolvency set-off applies to any mutual dealings between the insolvent party and the creditor that existed before the commencement of proceedings, without requiring a separate notice.
• Future and contingent obligations: Unlike Section 53 set-off, insolvency set-off can encompass debts that were not yet due, as long as they arose from dealings that pre-dated the insolvency.
• No inequality of treatment: Insolvency set-off is not treated as a preference or a fraudulent transfer, even if one debt is extinguished before formal insolvency proceedings begin, provided it was a genuine pre-existing obligation.
• Currency conversion: The Law addresses currency mismatches in mutual obligations, using the exchange rate at the date of the insolvency order to convert foreign-currency obligations for the purpose of calculating the net balance.

For foreign creditors of Israeli companies, insolvency set-off is a powerful tool. A foreign supplier that is owed payment for goods it has delivered, but that also owes an advance deposit on future orders it will not now complete, can set off the deposit against the unpaid invoice and file only the net claim in the insolvency proceedings. This is significantly better than filing a gross claim as an unsecured creditor while also being obliged to pay the deposit in full to the insolvency estate.

7. Bank Account Combination: A Related Right

Israeli banks exercise a right to combine accounts (kibbuz cheshbonot), which is functionally similar to set-off but arises specifically in the banking context. When a customer has both a credit balance on one account and an overdue debit balance on another, the bank may combine the accounts — effectively using the credit to satisfy the debit — without court authorization.

This right derives from the standard terms and conditions that Israeli banks incorporate into every account agreement, reinforced by judicial recognition in Israeli commercial law. The Banking (Service to Customer) Law 5741-1981 governs the relationship between banks and customers but does not expressly limit account combination; courts have generally upheld banks' rights to combine accounts where the standard terms permit it, provided the bank gives reasonable notice.

Investors and companies with Israeli subsidiaries often hold multiple accounts at the same Israeli bank. If one account runs a debit, the bank can satisfy it from a credit balance elsewhere without prior warning. Worth knowing:

• Monitor all accounts with the same Israeli bank, not just the primary operating account.
• Keep credit balances and loan accounts at different banks if you do not want combination to apply.
• Review the bank's standard terms carefully when opening accounts in Israel; account combination rights are almost always included.

8. Practical Guidance for Foreign Parties Dealing with Israeli Counterparties

Foreign nationals and businesses doing business in Israel run into set-off questions more often than they might expect. The three scenarios below cover most of them.

When You Are Owed Money and Also Owe Money to the Same Israeli Party

Before paying an Israeli counterparty, check whether you also hold a cross-claim against them: an unpaid invoice, a deposit, a damages claim arising from a breach of contract, or any other monetary obligation they owe you. If the cross-claim satisfies the requirements of Section 53 — it is monetary, due, and liquidatable — you are entitled to set it off by notice before paying.

Send a written set-off notice identifying both obligations and stating the net balance. Keep a copy. If the counterparty disputes the cross-debt, you will need to defend the validity of the set-off in court, but you will have preserved your legal position.

When an Israeli Party Claims Set-Off Against You

If an Israeli counterparty sends you a set-off notice claiming that a debt you owe them is extinguished against a cross-debt they assert, review the notice carefully. Check whether the purported cross-debt:

• Is actually owed to them (is there a valid, enforceable obligation?)
• Was due and payable at the time of the notice
• Is for a liquidated, determinable amount
• Is not barred by limitation or already settled

If the set-off is invalid — for example, the cross-debt is disputed or not yet due — you can reject the notice and demand payment in full. Explain in writing which condition was not satisfied. The burden of proving a valid set-off rests on the party asserting it.

Drafting Contracts with Israeli Parties

If you want to prevent the other party from withholding payments by asserting disputed set-offs — common in construction, real estate, and software development projects — include an explicit set-off exclusion clause in the contract. Something to the effect of: "Payment obligations under this Agreement are independent and unconditional; no Party may set off any alleged claim against amounts due under this Agreement without the prior written consent of the other Party." Israeli courts will generally enforce such clauses in business-to-business contracts.

Conversely, if you want to preserve set-off rights, do not sign contracts containing broad set-off waivers without understanding their effect. Such waivers can leave you paying in full while having to litigate your cross-claim separately.
