The Hague Conference has been working (with the National
Notary Association in the US) to develop a system
of electronic apostilles, and a
few countries have started producing them.
The list
of regulated professions concerned includes mostly the different legal professions: lawyers (avocats), as well as
notaries (notaires) and bailiffs (huissiers de justice), to name a
few (as explained in the first post relating to France, the country has several regulated legal professions).
