What Makes a Foreign Law Declaration Persuasive in Court

By: Adv. Eli Shimony

Foreign law issues in Israeli proceedings are rarely academic. The way a court understands and applies foreign law can decide who wins a contract dispute, whether a will is enforced, how a cross-border real estate deal is interpreted, or how corporate rights are allocated. When that foreign law is disputed, what often tips the balance is the quality of the Israeli law expert declaration that explains the foreign rules to an Israeli judge.

In our experience as an Israeli lawyer team working on international matters, foreign law declarations are frequently treated as a formality or left to the last minute. That is a mistake. We want to explain what actually makes such a declaration persuasive, how courts look at these documents, and how a coordinated approach between local and foreign counsel can significantly strengthen your case.

Why Foreign Law Declarations Matter so Much

Israeli courts generally do not take judicial notice of foreign law. Foreign law is treated as a matter of fact, which means it has to be proven. This often arises in cross-border contracts, inheritance disputes involving heirs abroad, real estate investments involving foreign companies, and corporate or shareholder conflicts where foreign law governs the company or transaction.

An Israeli law expert declaration on foreign law serves as a bridge between legal systems. The court needs help understanding not only the wording of foreign statutes, but also how courts in that country interpret them in practice, what procedures apply, and how judges there resolve similar disputes. Without that bridge, the court may struggle to apply the correct rules or may even default to Israeli law.

What is at stake is significant. A weak declaration can lead to misinterpretation of foreign law, give more weight to the opposing expert, or, in some cases, result in dismissal of key claims for lack of proper proof. A clear, balanced, and well-reasoned declaration, on the other hand, can give the court confidence in your legal theory and support a favorable ruling.

Legal Framework and Core Requirements in Israel

Under Israeli procedure, foreign law is something you must prove, like any other factual issue. That proof typically consists of:

1. An expert declaration on foreign law.

2. Clear references to statutes and regulations.

3. Selected foreign judgments or academic commentary.

4. Sometimes, supporting pleadings that explain how the foreign rules fit the facts.

Courts expect a foreign law declaration to be quite specific. It should identify the relevant foreign jurisdiction, define the exact legal questions, cite the applicable statutory provisions, and discuss case law that is binding or persuasive in that legal system. Vague references to “general principles” are rarely enough.

Timing also matters. Foreign law issues should usually be flagged in the pleadings, not introduced late in the process. Submitting an expert declaration only at an advanced stage, or changing positions about which foreign rules apply, can damage credibility both in the eyes of the judge and of the Israeli lawyer presenting the case. Early, consistent presentation allows the court to understand from the outset that foreign law is central and needs structured evidence.

What Makes a Foreign Law Expert Witness Credible

Israeli judges look closely at the person behind the declaration. The expert must appear independent and objective. A persuasive Israeli law expert declaration reads like a legal analysis prepared for the court, not like a partisan brief dressed up as expertise.

Credibility is supported by clear credentials, such as:

1. Admission to the bar in the relevant foreign jurisdiction.

2. Significant practical experience with the subject area in that foreign system.

3. Academic positions or teaching roles related to that law.

4. Published articles or treatises on the relevant topic.

5. Prior experience giving expert testimony on the same foreign law.

Another important feature is the expert’s familiarity with Israeli procedure and evidentiary rules. An expert who understands how Israeli courts read affidavits, evaluate credibility, and manage cross-examination can structure the declaration so it is easy for an Israeli judge and for the Israeli lawyer arguing the case to rely on it. This often means anticipating questions the court is likely to ask and answering them directly in the text.

How to Structure a Persuasive Declaration

Form matters almost as much as substance. A well-organized declaration usually follows a clear pattern:

1. Background of the expert and summary of qualifications.

2. Explanation of the instructions received and materials reviewed.

3. Definition of the foreign legal issues the court must decide.

4. Presentation of relevant statutes, case law, and secondary sources.

5. Application of those rules to the facts as assumed or established.

6. A reasoned conclusion, explaining not just what the law is, but why.

Transparent legal reasoning is essential. The expert should quote key statutory provisions, explain the hierarchy of sources in the foreign system, and describe how courts there have applied the rules, including any important exceptions. If there is contrary or unsettled authority, the declaration should confront it head-on and explain why one line of cases is more persuasive or more likely to be followed.

Because the court and the parties may not be familiar with foreign legal terms, drafting should be as clear as possible. That means plain language, short explanations of technical concepts, and careful translations. Consistent terminology makes it easier for everyone involved to follow the argument from section to section.

Common Substantive and Procedural Pitfalls

We often see foreign law declarations weakened by avoidable errors. On the substantive side, typical problems include:

1. Oversimplifying complex foreign rules.

2. Ignoring recent legislative or case law developments.

3. Selecting only favorable cases without explaining opposing decisions.

4. Presenting personal views as if they were established law.

Procedurally, courts may give less weight to a declaration that suffers from:

1. Missing or incomplete exhibits of statutes or judgments.

2. Lack of certified or reliable translations when needed.

3. Failure to link each legal principle to specific disputed facts.

4. Poor coordination with pleadings or other evidence.

Tone can also harm credibility. An expert who attacks the opposing expert in sharp or personal language, or who writes in an obviously argumentative style, risks being seen as an advocate instead of an objective guide. When that happens, the court may give both experts less weight and rely more heavily on its own interpretation, which may not favor either party.

Coordinating Local and Foreign Counsel for Strategic Impact

The most persuasive foreign law declarations are usually the result of careful coordination between local Israeli litigators and foreign counsel. The foreign expert understands the substantive law, but the Israeli lawyer knows how the court thinks, what issues are decisive, and which facts are likely to be accepted as proven.

To keep everything aligned, it helps to:

1. Engage the foreign expert early, ideally at the pleadings stage.

2. Agree on the factual assumptions that the declaration will use.

3. Ensure consistency with witness statements, documents, and pleadings.

4. Conduct mock cross-examinations to test the clarity and resilience of the opinion.

When more than one foreign jurisdiction is involved, or when several experts are needed for different areas of law, planning becomes even more important. Conflicting assumptions or inconsistent terminology between experts can be exploited by opposing counsel and may confuse the court.

Treating the foreign law declaration as a strategic tool rather than a formal requirement shifts the mindset. A carefully designed Israeli law expert declaration can support interim motions, help structure settlement discussions by clarifying risk, and create a thorough record that an appellate court can later review with confidence.
