Letter of request vs. letter rogatory: Key differences explained

On Behalf of | Aug 6, 2024 | Business Law |

When dealing with legal matters in Massachusetts, understanding the distinctions between a letter of request and a letter rogatory is necessary. 

Both are used in legal proceedings to obtain information or evidence from another jurisdiction. However, they serve different purposes and follow different procedures.

Letter of request

A letter of request (letter of mutual assistance) is helpful in domestic legal proceedings within the United States. It is a formal request from one court to another in the same country to obtain evidence, documents, or testimony. 

They’re a familiar tool in all criminal and civil cases, including business legal disputes. It is often used when the information or witnesses needed are located outside the jurisdiction of the requesting court. 

For example, if a Massachusetts court needs documents from a case in California, it will issue a letter of request to the California court. It can streamline the process through cooperation between courts within the same legal system.

Letter rogatory

In contrast, a letter rogatory is helpful in international cases. It is a formal request sent from a court in one country to a court in another country. 

This type of letter can be helpful when a party in a case needs evidence or testimony from someone in a foreign jurisdiction. It follows a more complex procedure due to differing legal systems and requirements across borders.

Understanding the distinctions between a letter of request and a letter rogatory is essential for effectively navigating legal proceedings. Knowing when and how to use these legal tools ensures that obtaining evidence or testimony runs smoothly and adheres to the appropriate legal protocols.
