Russian Law in US Litigation: Rule 44.1, Declarations and Expert Evidence
Practical guide for US litigators, trial counsel and arbitration lawyers on Russian law issues in US litigation, Rule 44.1, expert declarations, affidavits, depositions and foreign law evidence.
Russian Law in US Litigation: Rule 44.1, Declarations and Expert Evidence
Russia-related disputes often reach US litigation even when the underlying facts, documents or parties are located far from the United States. A contract may be governed by Russian law. A Russian company may be a defendant, borrower, guarantor, shareholder or counterparty. A disputed transaction may depend on Russian corporate authority. A limitation issue may turn on Russian civil law. A sanctions-affected payment may require analysis of Russian legal consequences. Parallel Russian proceedings may affect enforcement strategy or litigation risk.
For US litigators, trial counsel, federal court practitioners and arbitration lawyers, the practical question is not simply: “What does the Russian statute say?” The more important question is: how should Russian law be presented to the US court, tribunal or legal team in a form that is accurate, independent and useful?
This article explains, from the perspective of a Russian law expert assisting US counsel, when a Russian law expert declaration or affidavit may be needed, how Federal Rule of Civil Procedure 44.1 works, what topics Russian law evidence may cover, and what counsel should send before requesting an expert opinion.
This article does not provide advice on US procedural law. US counsel should determine procedural strategy, court filings, disclosure obligations, admissibility issues, privilege, deposition strategy and compliance with local rules. The role of the Russian law expert is to provide independent analysis of Russian law.

Why Russian Law Issues Arise in US Litigation
Russian law may become relevant in US litigation for many reasons. The dispute may involve a Russian party, Russian assets, a Russian-law contract, Russian court proceedings, Russian corporate documents, Russian regulatory measures or performance affected by sanctions and counter-sanctions.
Common examples include:
In these situations, US counsel may need more than translated excerpts from the Russian Civil Code or other legislation. The issue may require case-specific analysis of Russian statutes, court practice, corporate documents, procedural history and factual assumptions.
A useful Russian law opinion explains how Russian law applies to the actual dispute.
Common examples include:
- a supply, loan, guarantee, settlement or share purchase agreement governed by Russian law;
- a US proceeding involving a Russian company or individual;
- disputed authority of a Russian company’s general director, representative or attorney-in-fact;
- Russian limitation periods or time-bar issues;
- validity, invalidity, termination or enforceability of contracts under Russian law;
- Russian insolvency, bankruptcy or asset recovery issues;
- parallel proceedings in Russian arbitrazh courts;
- sanctions-affected payment, performance or non-performance;
- enforcement risk involving assets, judgments or arbitral awards connected with Russia.

Rule 44.1 in Plain English
Federal Rule of Civil Procedure 44.1 provides the basic framework for determining foreign law in US federal civil litigation. The rule states that a party intending to raise an issue about foreign law must give notice by a pleading or other writing. It also states that, in determining foreign law, the court may consider any relevant material or source, including testimony, whether or not submitted by a party and whether or not admissible under the Federal Rules of Evidence. The court’s determination is treated as a ruling on a question of law.
For US litigators, three points are especially important.
First, foreign law is not simply a factual issue presented to the jury in the same way as ordinary fact evidence. Under Rule 44.1, the court determines foreign law as a question of law.
Second, the court has flexibility. It may consider relevant materials or sources, including expert testimony, legal materials, translations, declarations, affidavits and other sources that assist the foreign law determination.
Third, notice matters. Counsel should identify early whether Russian law will be raised and how the issue will be presented.
This does not mean that every Russian law issue requires a lengthy expert report. Some issues may be narrow, agreed or capable of being addressed through limited materials. But where Russian law is contested, material or complex, an independent Russian law expert declaration may be essential.

Rule 44.1 Is Not a Substitute for Good Expert Work
Rule 44.1 gives the court flexibility, but flexibility does not remove the need for clear analysis.
A weak Russian law submission may quote translated statutes without explaining context. It may ignore Russian court practice. It may use English legal labels that do not map accurately onto Russian concepts. It may assume that Russian company law, contract law or limitation principles operate like US law. It may present advocacy rather than independent legal analysis.
A strong Russian law declaration does the opposite. It identifies the questions, states the assumptions, reviews the relevant Russian sources, explains the legal framework, applies Russian law to the facts assumed by US counsel, and identifies any material uncertainty.
The goal is not to overwhelm the court with Russian legal materials. The goal is to make the Russian law issue understandable and reliable.

Declaration, Affidavit, Report or Legal Memorandum?
US counsel may use different formats depending on the procedural setting and strategic purpose.
Russian Law Legal Memorandum
A legal memorandum is usually an internal document for counsel or the client. It may help assess pleadings, strategy, settlement, motion practice or whether Russian law is likely to be material.
A memorandum can be fast and practical. It is often useful before deciding whether to prepare a formal declaration.

Russian Law Expert Opinion
An expert opinion is a structured analysis of Russian law. It may be used for case assessment, arbitration, settlement discussions, client advice or preparation for litigation filings.
It may be less formal than a declaration, but should still be reasoned, sourced and based on clear assumptions.

Rule 44.1 Declaration
A Rule 44.1 declaration is commonly used when US counsel wants to submit Russian law analysis to a federal court. It should be written in clear English, explain the expert’s qualifications, identify the materials reviewed, and answer the specific Russian law questions.
The declaration should not read like a party brief. It should assist US counsel and the court by explaining Russian law independently.

Affidavit
An affidavit may be required in some procedural contexts. The formal requirements should be determined by US counsel. From the Russian law expert’s perspective, the substance should remain accurate, complete and independent.
Expert Report
In some US cases, the Russian law expert may be treated procedurally as an expert witness whose opinions may be disclosed under Rule 26. Rule 26(a)(2) addresses disclosure of expert testimony, including disclosure of the identity of an expert witness and, for certain retained experts, a written report containing the expert’s opinions, the basis and reasons for them, facts or data considered, exhibits, qualifications, prior testimony and compensation.
US counsel should decide whether Rule 26 expert disclosure requirements, local rules, scheduling orders or evidentiary rules apply to a particular Russian law expert engagement.

When a Russian Law Expert Declaration May Be Needed
A Russian law expert declaration may be useful whenever the court or opposing party needs a reliable explanation of Russian law. The following categories are common.
Russian Contract Law
Russian contract law issues may arise where a contract is governed by Russian law or where Russian legal consequences affect performance.
The expert may be asked to address formation, interpretation, validity, termination, breach, damages, penalties, interest, assignment, set-off, force majeure or mandatory provisions.
For example, a US court may need to understand whether a notice of termination was effective under Russian law, whether a contractual penalty is enforceable, whether a party’s non-performance has a recognised legal consequence, or how Russian law treats a payment obligation affected by external restrictions.

Corporate Authority and Russian Companies
Disputes involving Russian companies often raise authority and capacity issues.
A Russian law expert may analyse whether a Russian company’s general director had authority to sign, whether a power of attorney was valid, whether corporate approval was required, whether a transaction was major or interested-party in nature, or whether charter documents affected the analysis.
These issues often require review of Russian-language corporate documents, register extracts, resolutions, powers of attorney and transaction documents. A translation may show the words used. It will not necessarily explain the Russian legal consequences.

Limitation Periods
Limitation can be a decisive Russian law issue.
A declaration may address the applicable limitation period, when it begins, whether it was suspended or interrupted, whether acknowledgement of debt affected the period, or whether prior proceedings changed the analysis.
US counsel should raise limitation issues early. If Russian limitation law affects pleadings, motions, settlement leverage or enforcement strategy, waiting until late in the case may create avoidable risk.

Russian Proceedings and Arbitrazh Court Procedure
Russian court procedure may become relevant where there are parallel proceedings, prior judgments, appeals, enforcement steps, bankruptcy proceedings or interim measures in Russia.
A Russian law expert may explain the status of Russian proceedings, the role of arbitrazh courts, procedural stages, appeal periods, finality, service, jurisdiction, enforcement mechanisms or the practical meaning of Russian procedural documents.
This is a frequent area where literal translation is not enough. Russian procedural terminology can be misleading if interpreted through US litigation concepts.

Sanctions-Affected Performance
Russia-related disputes often involve sanctions, counter-sanctions and regulatory restrictions.
US sanctions advice should be given by qualified US counsel. A Russian law expert’s role is different. The expert may explain Russian legal measures, Russian countermeasures, payment restrictions, regulatory approvals, Russian court practice, or the Russian law consequences of performance or non-performance.
The Russian law analysis should be carefully scoped so that it supports US counsel without crossing into US sanctions advice.

Enforcement Risk and Russian Assets
A Russian law declaration may be needed where US counsel is considering recognition, enforcement, asset recovery or settlement strategy involving Russia.
The expert may address whether a foreign judgment or arbitral award may face Russian law issues, whether parallel Russian proceedings create risk, whether Russian bankruptcy proceedings affect recovery, or what Russian procedural steps may matter.
The expert should not guarantee enforcement outcomes. The proper role is to identify Russian law rules, risks and practical considerations based on the documents and assumptions provided.

What to Send to the Russian Law Expert
A focused instruction pack helps the expert provide a faster and more useful response.
What to send | Why it matters |
Parties and related entities | Required for conflict check before sensitive documents are reviewed. |
Court, case number and procedural posture | Helps identify whether the matter involves motion practice, discovery, trial, arbitration or enforcement planning. |
Pleadings, complaint, answer or motion papers | Shows how Russian law is relevant to the live issues. |
Scheduling order or procedural timetable | Determines deadlines for declarations, rebuttal materials, deposition or trial preparation. |
Contracts and amendments | Essential for Russian-law contract issues. |
Corporate documents | Relevant to authority, capacity, approvals, powers of attorney and company status. |
Correspondence and notices | May affect termination, acknowledgement, limitation, performance and factual assumptions. |
Russian court documents | Important for parallel proceedings, procedural status, enforcement risk and Russian litigation history. |
Sanctions context | Helps separate Russian law analysis from US sanctions advice handled by US counsel. |
Proposed questions | Keeps the declaration focused and avoids unnecessary cost. |
Required format | Clarifies whether counsel needs a memo, opinion, Rule 44.1 declaration, affidavit, expert report or deposition support. |
How to Frame Questions for the Expert
The best questions are neutral, precise and tied to factual assumptions.
Poor question:
“Please confirm that the Russian company lacked authority.”
Better question:
“Under Russian law, assuming the facts set out in the instructions, did the general director of the Russian company have authority to sign the agreement? What corporate documents, approvals or registry materials are relevant to that analysis?”
Poor question:
“Please support our argument that the claim is time-barred.”
Better question:
“What limitation period would apply under Russian law to the claim described in the complaint? When would that period begin, and what facts could affect suspension, interruption or expiry?”
Poor question:
“Please explain why Russian law excuses non-performance because of sanctions.”
Better question:
“What Russian law rules or measures may be relevant to the party’s ability or obligation to perform the payment obligations described in the contract, assuming the sanctions context summarised by US counsel?”
Good questions avoid advocacy. They ask for Russian law analysis, not a litigation slogan.

Preparing for Deposition
A Russian law expert may be deposed if counsel identifies the expert for testimony or if the procedural posture requires it. Rule 26 also provides that a party may depose a person identified as an expert whose opinions may be presented at trial, and where a report is required, the deposition may be conducted only after the report is provided.
Deposition preparation should focus on clarity, sources and assumptions.
US counsel and the expert should review:
The expert should be ready to explain Russian law clearly, but should not become an advocate. If a question concerns US law, US procedure, witness credibility or disputed facts outside the expert’s role, the expert should identify that limit.
Deposition preparation should focus on clarity, sources and assumptions.
US counsel and the expert should review:
- the declaration or report;
- the Russian legal sources cited;
- the documents reviewed;
- the factual assumptions used;
- any translations relied on;
- possible areas of disagreement with the opposing expert;
- the limits of the expert’s opinion;
- issues outside the expert’s expertise.
The expert should be ready to explain Russian law clearly, but should not become an advocate. If a question concerns US law, US procedure, witness credibility or disputed facts outside the expert’s role, the expert should identify that limit.
Independence and No Advocacy
A Russian law expert is most useful when the analysis is independent.
An expert declaration should not exaggerate certainty, ignore inconvenient materials, or present Russian law as simpler than it is. If there is a range of possible Russian law views, the expert should explain it. If the answer depends on disputed facts, the expert should say so. If the issue belongs to US counsel, sanctions counsel or another specialist, the expert should identify the boundary.
This independence benefits the legal team. It helps US counsel understand risk, anticipate opposing arguments, prepare motion papers and make informed settlement decisions.
