Do documents signed abroad need an apostille?

Usually yes. Signatures on the founding documents that are made outside Bulgaria are notarised where you sign and then apostilled, and the documents are translated into Bulgarian by a sworn translator. Bulgaria is a party to the Hague Apostille Convention, so an apostille from another Convention country is accepted without consular legalisation. We tell you exactly which documents to sign before you book a notary.
