The Federal Chancellery’s Personnel und Resources Section is responsible for certifying the authenticity of original signatures on documents required abroad.
What has to be certified?
Signatures from administrative offices of the Federal Administration, including from Swiss embassies and consulates, foreign diplomatic missions and consulates in Switzerland, cantonal chancelleries and organisations that carry out public duties in the general interest of the country (Article 8, Organisation Ordinance for the Federal Chancellery, SR 172.210.10).
Certification by apostille
For states which are party to the Hague Convention, certification in the form of an apostille is sufficient. Documents do not need to be certified by a consular agent and are otherwise recognised in the country for which they are intended (Article 2, Hague Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents).
For all states which are not party to the Hague Convention, the normal certification process without apostille applies, in which authentication by a consular or diplomatic agent is required.
