The BIE "registers" or "recognises" the Expo
After the vote, the future host country must formalise its Expo project by submitting a complete and definitive implementation plan for the Expo. This formalisation is called "registration" for World Expos and "recognition" for Specialised Expos.
For World Expos, the registration dossier must be submitted to the BIE at least five years before the opening date. For Specialised Expos, the recognition dossier must be submitted at least four years before the opening date.
The registration or recognition dossiers must address:
- Legislative and financial measures
- The legal status of the Expo organisers
- The development of the theme (theme selection, its definition, its development, applications)
- The duration of the Expo
- The master plan of the site
- The financial plan
- A preliminary promotional and communication plan (national and international)
- Post-Expo plan
- The commercial strategy of the organisers
The dossier must be accompanied by the Expo's general regulations, the participation contracts that will be addressed to the future participants, the documents establishing and guaranteeing compensation in case of cancellation and any special regulations regarding the theme, the financial and material conditions for participation and the measures to minimize participation costs.
