International depositions are no longer occasional events reserved for exceptional cases. For many law firms, they are now a recurring part of discovery planning. Witnesses, experts, and key decision-makers are increasingly located outside the country, and testimony must be obtained in jurisdictions with their own legal systems, procedural limits, and enforcement realities. 

The primary risk is not logistical inconvenience. It is assuming that U.S. procedural compliance alone is sufficient. In many jurisdictions, conducting an unauthorized deposition is not a technical defect. It is a violation of local law that can invalidate testimony or halt proceedings altogether. 

This guide is intended to help law firms, attorneys, and paralegals approach international depositions in 2026 with clearer expectations, proper planning, and fewer avoidable complications. 

Understanding the Legal Framework 

International depositions are governed by two overlapping legal systems. One derives authority from international treaty obligations. The other arises from U.S. procedural law. Both apply, and neither can be treated as secondary. 

Understanding how these frameworks interact is essential to determining whether testimony can be taken, who may conduct it, and what procedural safeguards must be observed. 

Treaty-Based Authority 

The Hague Convention on the Taking of Evidence Abroad in Civil or Commercial Matters is the principal treaty governing cross-border evidence gathering. It provides a formal mechanism by which a U.S. court may request assistance from a foreign judicial authority through a Letter of Request, sometimes referred to as a Hague request. The receiving state executes the request according to its own domestic procedures, not U.S. discovery rules. 

The Convention is designed to balance cooperation with sovereignty. While it facilitates evidence gathering, it expressly allows each contracting state to limit how evidence may be obtained within its territory. These limitations appear in the form of country-specific declarations and reservations, which are binding on requesting courts and litigants. 

As a result, the Convention does not create a uniform deposition process. Instead, it establishes a framework within which each country defines what is permissible. Some states allow voluntary depositions conducted by foreign counsel. Others require that testimony be taken only by local courts or judicial officers. Many restrict or prohibit compulsion entirely. 

The Hague Conference on Private International Law maintains an official status table and country-by-country declarations, which are essential planning tools for any international deposition. Treaty membership alone does not establish permissibility. The controlling factor is how the receiving state has chosen to implement the Convention. 

U.S. Procedural Authority 

From the U.S. perspective, Federal Rule of Civil Procedure 28(b) governs the manner in which depositions may be taken in foreign countries. The Rule permits depositions abroad by four methods: pursuant to an applicable treaty, under a letter of request or letter rogatory, before a person authorized to administer oaths under local or U.S. law, or before a person commissioned by the court. 

Rule 28(b) defines what is acceptable under U.S. procedure. It does not grant authority to act within a foreign jurisdiction. The Advisory Committee Notes expressly caution that some countries are hostile to depositions conducted by foreign litigants, and that advance examination of foreign law is necessary to avoid violations or failed testimony. 

This distinction is critical. A deposition that is procedurally valid under Rule 28(b) may still be unlawful where taken. In such cases, the testimony may be interrupted, refused execution by foreign authorities, or later challenged on admissibility grounds. 

In practice, once it is confirmed that a jurisdiction permits a voluntary U.S.-style deposition, most international depositions proceed by stipulation among counsel that the court reporter may administer the oath and create the record. This reflects common practice we observe when coordinating cross-border depositions.  

How the Two Systems Interact in Practice 

In planning terms, treaty authority determines whether testimony may be taken in a given country and under what constraints. U.S. procedural authority determines how that testimony must be structured to be usable in U.S. proceedings. 

Neither system is optional. A legally compliant international deposition requires alignment between both. 

The U.S. Department of State’s Judicial Assistance Country Information pages reflect this dual framework. These resources explain, on a country-by-country basis, whether depositions are permitted, whether prior approval is required, and whether testimony must be taken through treaty mechanisms rather than by private arrangement. 

This means that international depositions must be evaluated as jurisdiction-specific exercises. The applicable treaty framework, local implementing law, and U.S. procedural requirements together determine whether testimony can be taken at all and what method will produce a defensible record. 

Jurisdictional Constraints on International Depositions 

When planning international depositions, jurisdictions do not vary by degree. They vary by legal posture. For practical purposes, countries tend to fall into three distinct categories, each with direct consequences for how testimony may be obtained and whether it can be taken at all. 

Understanding which category applies is an essential planning step. It determines whether a deposition can proceed by agreement, requires formal judicial assistance, or must be relocated entirely.  

Jurisdictions That Prohibit Foreign Depositions 

Some countries prohibit foreign attorneys from taking depositions within their territory under any circumstances. This prohibition applies regardless of witness consent and extends to testimony conducted by telephone or videoconference. 

China, Brazil, and Russia are the most frequently encountered examples. 

In these jurisdictions, evidence gathering for foreign proceedings is treated as an exclusive judicial function. Private depositions conducted by foreign counsel are considered an infringement on sovereignty. As a result, testimony must be obtained through formal judicial assistance mechanisms, typically under the Hague Evidence Convention or by letters rogatory, and is often taken by local courts rather than by U.S. attorneys. 

For example, China does not permit depositions taken on notice, and unauthorized testimony may expose participants to legal penalties. Brazil permits testimony for foreign proceedings only through Brazilian judicial authorities, including remote testimony. Russia does not permit voluntary depositions in civil or commercial matters at all, and has suspended judicial cooperation in civil and commercial matters with the U.S. 

Testimony involving witnesses in these jurisdictions must be evaluated early. If formal judicial assistance is impractical or timelines do not permit it, relocating the witness to a permissible jurisdiction may be the only viable option. 

Jurisdictions That Permit Depositions Under Defined Conditions 

A second group of countries allows depositions, but only under tightly regulated conditions. These conditions often control venue, supervision, and advance authorization. 

Japan, Germany, and France are representative examples. 

In these jurisdictions, depositions are typically permitted only on U.S. embassy or consular premises and often require advance approval from local authorities. Japan requires that depositions be conducted before a U.S. consular officer pursuant to a court order or commission. Germany requires the pre-approval of deposition requests by the German Ministry of Justice. France mandates that depositions be conducted on U.S. Embassy or Consulate premises and open to the public.  

These jurisdictions require additional lead time. Embassy scheduling, government approvals, and visa requirements often dictate the deposition timeline more than discovery deadlines. 

Jurisdictions That Generally Permit Voluntary Depositions 

A third group of jurisdictions allows voluntary depositions with fewer formal barriers, provided the witness consents and no compulsion is used. 

The United Kingdom, Canada, and Hong Kong fall into this category. These jurisdictions generally permit foreign counsel to conduct voluntary depositions without prior government approval, although court involvement is still required to compel testimony or production. 

These jurisdictions offer more flexibility, but they do not eliminate the need for verification. Assumptions about permissibility still need to be confirmed against current guidance. Canada, for example, is not a party to the Hague Evidence Convention, which affects how formal requests must be made if compulsion is required. The United Kingdom permits voluntary depositions but requires court authorization for compelled testimony. 

The Next Operational Steps 

Once it is established that testimony may lawfully be taken in a given jurisdiction, the next set of decisions is operational. These would determine whether the deposition proceeds predictably or becomes vulnerable to delay, confusion, or procedural challenge. Unlike domestic matters, many of these choices cannot be adjusted once testimony is scheduled. 

Deposition Format and Location 

The selection of format, whether in person or remote, must be driven by the law of the jurisdiction where the witness is physically located. Cost and convenience are secondary considerations. 

Remote testimony does not bypass jurisdictional limits. Under U.S. and foreign practice, testimony is deemed taken where the witness sits, not where counsel appears. As a result, jurisdictions that prohibit or restrict in-country depositions generally apply those rules equally to videoconference testimony. 

Oath Administration and Record Authority 

Record creation in an international deposition begins with authority to administer the oath. This is not uniform across jurisdictions. 

Federal Rule of Civil Procedure 28(b) permits depositions abroad before a person authorized to administer oaths under U.S. law or the law of the place of examination. In practice, some jurisdictions accept oaths administered by U.S. court reporters acting under U.S. authority. Others require oaths to be administered by consular officers or locally authorized officials.  

These requirements directly affect who must be scheduled, what facilities may be used, and how far in advance arrangements must be made. 

Language and Interpretation Planning 

Where testimony will be taken in a language other than English, interpretation is not a support function. It is part of the evidentiary record. 

Depositions typically proceed through consecutive interpretation, which affects timing, transcript structure, and exhibit handling. Court interpreters are expected to be trained in legal proceedings and deposition protocol. Interpretation errors are not easily corrected after the fact and can materially affect the usefulness of the transcript. 

Professional legal interpreting standards are addressed in guidance from courts and arbitration institutions, and many jurisdictions require interpreters to meet certification or qualification standards when testimony is taken under judicial authority. 

Documentation and Approval Timelines 

International depositions frequently require advance documentation that does not exist in domestic practice. These may include court commissions, letters of request under the Hague Evidence Convention, consular permissions, and visas for attending counsel. 

These approvals often involve third-party authorities and fixed processing times. For example, letters rogatory transmitted through diplomatic channels may take many months to execute. Embassy-based depositions are subject to facility availability and government notice requirements. 

Bring Structure to Complex International Deposition Planning 

International depositions tend to expose weaknesses in planning that remain hidden in domestic matters. Assumptions that ordinarily hold in U.S. discovery often break down once testimony crosses borders. Legal authority becomes fragmented, procedural options narrow, and timelines are influenced by actors outside the litigation team’s control. 

What distinguishes effective international deposition practice is not familiarity with every jurisdiction, but discipline in verification. Knowing when local law governs, when treaty mechanisms apply, and when informal approaches are not available allows legal teams to make decisions with greater confidence and fewer corrective steps later in the process. 

As cross-border matters continue to increase, international depositions warrant the same level of deliberate planning applied to jurisdiction, venue, and governing law. Each carries consequences that extend beyond scheduling and into admissibility, enforceability, and case strategy. 

Optima Juris works with legal teams to support this planning by coordinating jurisdiction-specific requirements with court reporting, interpretation, and procedural execution, helping international testimony proceed on a sound footing and with fewer avoidable disruptions. Contact us today for more information.
