Classification of Law
Estonia's legal system is a mixture of Roman civil law and Anglo-American common law systems. Civil law operates in areas such as family relations, property, succession, and contracts while statutes and principles of common law origin are evident in areas such as constitutional law, procedural law, corporations law, taxation, insurance, labour relations, banking and currency.
Civil law systems are based on concepts derived from old Roman law, distinguishable by their reliance on having a comprehensive set of rules and principles codified and easily accessible to both citizens and legal professionals. Codified laws are regularly revised to reflect the current environment, and have stronger emphasis in civil law countries than any precedent set by earlier court cases. Civil law countries cover more than 65% of world’s legal system, including the majority of continental Europe, Central and South America, the Middle East, Asia and Africa.
eSignature Legality Summary
Under Estonian law, a written signature is not necessarily required for a valid contract - contracts are generally valid if legally competent parties reach an agreement, whether they agree verbally, electronically or in a physical paper document (Art. 9 Sect. 1 and Art. 11 Sect. 1 of the Law of Obligations Act), unless the law sets forth a specific format requirement. To prove that a contract is valid, parties sometimes have to present evidence in court. Leading digital transaction management solutions can provide electronic records in order to substantiate that a contract exists, is authentic, and valid. Such elexctronic records are admissible asevidence under Art. 274 of the Code of Civil Procedure.
In addition, Regulation (EU) No 910/2014 on electronic identification and trust services for electronic transactions in the internal market (the “eIDAS Regulation”) came into force on 1 July 2016. The eIDAS Regulation repealed and replaced the e-Signatures Directive (1999/93/EC) and is directly applicable in all 28 Member States of the European Union.
The eIDAS Regulation is technology neutral and defines three types of electronic signature (SES, AES, QES). Art. 25 Sect. (1) of the eIDAS Regulation provides that an electronic signature shall not be denied legal effect and admissibility as evidence in legal proceedings solely on the grounds that it is in an electronic form or does not meet the requirements of a QES. Art. 25 Sects. (2) and (3) give a QES the same legal effect as a handwritten signature and ensure that a QES recognized in one Member State of the EU is also recognized in other Member States. Finally, recital 49 allows national law to set requirements regarding which type of electronic signature may be required in which circumstances.
Use Cases for Standard Electronic Signature (SES)
Use cases where an SES is typically appropriate, include:
- certain HR documents, including documents regarding employment terms and conditions that are not mandatory under Estonian law, privacy notices, benefits paperwork (unless benefits are individually agreed upon) and other new employee onboarding processes

 An AES is an “advanced electronic signature”, a type of electronic signature that meets the following requirements: (a) it is uniquely linked to the signatory; (b) it is capable of identifying the signatory; (c) it is created using means that are under the signatory’s sole control; and (d) it is linked to other electronic data in such a way that any alteration to the said data can be detected.
 A QES is an advanced electronic signature that is created by a qualified electronic signature creation device, and which is based on a qualified certificate for electronic signatures. A QES has the equivalent legal effect as a handwritten signature.
Local Technology Standards
As a Tiered eSignature Legal Model country, Estonia supports the concept of a QES (Qualified Electronic Signature), requiring independent accreditation for those signatures by an approved certification body. Estonia maintains a full list accessible to the public of authorized qualified electronic certificate providers together with other countries in the European Union.
