Legally, a document issued in Solothurn falls under State Chancellery in Solothurn. In practice our standard route frees you from that counter: a notarized certified copy is made from your upload and the apostille goes on it — a copy suffices, whatever the canton. The original only enters the picture if your destination expressly requires the apostille on the original.
Order an apostille →Upload a PDF or photo; a notary establishes the certified true copy (included) and that copy receives the apostille — processed through our Vaud office. Nothing to post, and identical turnaround whether the document comes from Solothurn or anywhere else.
Some authorities insist the apostille sit on the original issued in Solothurn: we then file with State Chancellery in Solothurn. Send us the original by registered mail after ordering (address confirmed by e-mail) — it comes back apostilled.
Criminal records and other federal documents belong to the Federal Chancellery in Berne, not to Solothurn. Tick «federal document» in the form — we route it.
Documents issued in the canton of Solothurn come in German. That is exactly what Germany, Austria and Liechtenstein want, and no translation is needed for them. For France, Italy, Spain, Latin America or most of the Middle East, a certified translation will almost certainly be required on top of the apostille — plan for it from the start rather than discovering it after the file is refused.
Solothurn is geographically fragmented — parts of the canton are enclaved within Bern and Basel-Landschaft — and that regularly misleads people about which chancellery is competent. Geography is irrelevant here: what counts is the authority named on the document, not how the map looks around it.
