The electronic signatures are based on the Act on strong electronic authentication and electronic signatures, and this in turn is based on the eIDAS EU regulation.

National legislation and other norms dictate how national and local authorities receive and process electronically signed documents. For example, in Finland documents with e-signature are accepted as default, as dictated by Finnish law 24.1.2003/13 Laki sähköisestä asioinnista viranomaistoiminnassa (in Finnish only)."
