What SIGILLA is for. When a document has to be used in a country that did not issue it — a diploma, a birth certificate, a power of attorney, a court ruling — it usually needs an apostille, a consular legalization, or a sworn translation before the destination authority will accept it. SIGILLA helps you identify the likely authority that issues the stamp in the issuing country, the likely receiving channel in the destination country, estimated cost and timing, and a local record of each step. This is the part of cross-border paperwork that AI can describe but cannot complete, and that competent authorities must still perform.
