Uniform Interstate Depositions and Discovery Act (UIDDA)

When discovery in one state requires a subpoena to a person or business located in another state, the UIDDA lets a party present the trial-state subpoena to the clerk in the discovery state, who then issues a local subpoena on the same terms — without opening a separate miscellaneous action or retaining local counsel solely for that step. The act governs subpoenas for depositions, documents, and inspection; it does not change how an initial summons is served across state lines, which still follows the receiving state’s rules.

Adoption status below is drawn from each state’s own adopting statute or court rule. Some states implement the act by statute, others by an amended rule of civil procedure (for example, a Rule 45.1). Select any state to read its adopting citation alongside its full service rules.
