Hague Evidence Convention
A treaty establishing Letters of Request procedures for obtaining evidence located in another member country for use in civil litigation.
The Hague Evidence Convention creates a Letter of Request procedure: a court sends a formal request through a Central Authority to a foreign judicial authority, which then executes the request under its own local evidence-gathering procedures rather than American-style depositions. Some member countries also allow direct depositions abroad through consular officers or appointed commissioners, but only where the destination country permits it.
In Societe Nationale Industrielle Aerospatiale v. U.S. District Court, the US Supreme Court held that the Convention is not the exclusive means of obtaining evidence from parties located in member countries — litigants may still use ordinary Federal Rules discovery directly, subject to an international comity balancing test. Many civil-law countries take the opposite view and treat the Convention as their exclusive channel, sometimes backed by blocking statutes that make direct foreign discovery a criminal offense against their own nationals.
Juricratic models the evidence-gathering path itself as a decision with real cost, time, and quality tradeoffs. Choosing between a Convention Letter of Request, direct discovery under domestic rules, and the risk of triggering a blocking statute changes the cost and reliability dials that ultimately feed the case's evidentiary-strength projection.
How it actually shows up
Counsel in multinational litigation decides whether to pursue evidence through a Hague Letter of Request or through direct discovery requests, weighing the destination country's blocking-statute exposure, reciprocity concerns, and the realistic timeline each path adds to the case.
- Is the Hague Evidence Convention mandatory for US litigants?
- No — under Aerospatiale, US courts may permit direct discovery from a party located in a member country instead of requiring a Letter of Request, subject to a comity analysis.
- What is a blocking statute?
- A blocking statute is a foreign law, most notably France's, that prohibits disclosing certain evidence for use in foreign proceedings outside the Hague Evidence Convention channel, sometimes with criminal penalties.
- How long does a Letter of Request take?
- It varies widely by country and can take many months, since it depends on the pace of the foreign judicial authority executing the request under its own procedures.
