Legalisation and apostille explained
Finland accepts foreign public documents only when their authenticity is verifiable. Countries in the Hague Apostille Convention, including India and Pakistan (which joined in 2023 and 2024 respectively for many document types), attach an apostille certificate from their designated authority. Where apostille is unavailable, the older chain legalisation route applies: home foreign ministry attestation, then the Finnish mission. Do this before leaving home; retro-fixing legalisation from inside Finland means couriering originals back and forth for months.
