What is included in letters rogatory?

On Behalf of | May 27, 2025 | Out-of-state Discovery - Letters Rogatory |

When trying to gather evidence or serve legal documents across state or national boundaries, letters rogatory are often necessary. These formal requests are issued by a court in one jurisdiction to a court in another, asking for judicial assistance in performing specific acts that would otherwise fall outside the issuing court’s authority.

Letters rogatory are especially relevant in out-of-state discovery when a party needs documents, testimony or service of process carried out in a different jurisdiction. While they are often used for international matters, they also apply when requests must cross state lines and no streamlined agreement or uniform process applies.

What are the important elements of letters rogatory

To be effective, letters rogatory must contain key elements that explain the requesting court’s need and justify the cooperation requested from the foreign or out-of-state court. These elements serve both as a legal foundation and as guidance for the court receiving the request.

  • A clear statement that judicial assistance is requested in the interest of justice
  • A short summary of the case, identifying the parties and the claims involved
  • The type of case and the type of help requested such as testimony, documents or service
  • Identifying information about the person involved such as full name, address or business title
  • A specific list of documents or categories of evidence needed
  • A list of written questions to be asked, if applicable
  • An explanation of the preferred procedures such as taking testimony under oath or allowing participation by representatives
  • A willingness to provide similar cooperation in return if the roles were reversed
  • An offer to cover any costs incurred by the receiving court

These requests must be signed by a judge and authenticated with a court seal. In many jurisdictions, a clerk’s signature is not valid. Time frames can vary significantly, and the process may take several months or longer, especially if it requires transmission through diplomatic channels.

Consider seeking legal guidance to better understand your rights and legal options when preparing or responding to letters rogatory in an out-of-state discovery matter.
