E-signature legality in Bulgaria
България
Electronic signatures are recognised in Bulgaria under eIDAS and ZEDEP.
The law in plain language
Bulgaria's Electronic Document and Electronic Signature Act (ZEDEP) was originally enacted in 2001 and revised in 2016 to align with eIDAS. Electronic signatures are admissible in Bulgarian courts. Qualified electronic signatures carry the same legal weight as handwritten signatures under § 13 ZEDEP.
- Primary framework
- eIDAS + Закон за електронния документ и електронния подпис (ZEDEP)
- National act
- Закон за електронния документ и електронния подпис (Electronic Document and Electronic Signature Act), 2001 (revised 2016 for eIDAS alignment)
Signature tiers recognised in {country}
Bulgaria recognises the three eIDAS-aligned tiers. The right tier depends on the contract — most B2B documents are fine with SES; AES adds an identity-binding factor; QES carries the legal force of a handwritten signature for documents that require written form.
The baseline — admissible as evidence in court. Suitable for everyday commercial contracts.
SES + a second factor (typically SMS) that uniquely binds the signature to the signer.
AES + a qualified certificate from a Qualified Trust Service Provider. Equivalent to a wet signature.
Routinely signed electronically
