Cross-Border Jurisdictional Protocol
São Tomé and Príncipe is not a party to the Hague Service Convention, so cross-border service from the United States generally relies on diplomatic channels and formal Letters Rogatory. Its legal system reflects its Portuguese colonial history, following a civil-law tradition similar to Portugal, Angola, and Cape Verde, with Portuguese as the official language.
We prepare and route formal Letters Rogatory through diplomatic channels to São Toméan judicial authorities, the standard pathway for U.S.-originated requests.
