eSignature Legality Summary

eSignatures are legally valid and admissible in the court of law. Sri Lanka follows an open model where e-signature can be submitted in court. Specific use cases for eSignatures are indicated in the ET Act.

The Electronic Transactions Act No. 19 of 2006 in Sri Lankan law highlights that a handwritten signature isn’t always needed for a contract to be considered credible, and that contracts can’t be refused for simply being electronic. They’ll usually be seen as such as long as legally able individuals have reached an agreement (this can be by agreeing verbally, electronically or by physically signing something). Under Section 21 of the ETA, e-signature solutions can be used to give electronic records that are admissible as evidence to support contracts in court.

Use Cases for eSignatures 

Use cases where an SES is typically appropriate include:


  • End user agreements including sales & service terms, new retail account opening documents, invoices, shipment details, user manual, EULAs, policies

Use Cases for Qualified Signatures 

Use cases where an AES is typically appropriate include:


  • Purchase, procurement and commercial agreements including invoices, trade and payment terms, certificates, NDAs, sales & distribution agreements, order acknowledgements.

Use Cases that are not appropriate for Electronic Signatures

Use cases that are specifically barred from digital or electronic processes or that include explicit requirements, such as handwritten (e.g. wet ink) signatures or formal notarial process that are not usually compatible with electronic signatures or digital transaction management.


  • *Handwritten – A license issued to a telecommunications system operator is required to be in writing (as under Section 17 (6) of the Telecommunications Act No 25 of 1991 (as amended) read with Section 23 (b) of the ETA)

“Digital Signature” means a transformation of a message using an asymmetric cryptosystem such that a person having the initial message and the signer’s public key can accurately determine
(a) whether the transformation was created using the private key that corresponds to the signer’s public key;
(b) whether the message has been altered since the transformation was made


[1] 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;
(d) it is linked to other electronic data in such a way that any alteration to the said data can be detected.


[2] A QES is a specific digital signature implementation that has met the particular specifications of a government, including using a secure signature creation device, and been certified as ‘qualified’ by either that government or a party contracted by that government.

The eSignature Legality Guide is the result of legal research into the laws and practices regarding eSignature on a country-by-country basis. Each country-level analysis was conducted by local law firms located in that country, in that country’s local language. This legal analysis was then supplemented with complementary research on eSignature and digital signature technology standards conducted by independent technology experts. Together, this information is provided as a public resource to understand eSignature legality, and clarify some of the common misconceptions about international eSignature legality.


A basic measure of eSignature legality in a country is whether courts will admit eSignatures as evidence in court. In most countries in the world, an eSignature cannot be rejected simply because it is electronic, meaning that it should be admissible, subject to proof.

While there are exceptions for very specific types of transactions, eSignatures, independent of the underlying technology, may be used for the majority of general business transactions in most countries. Issues that may restrict general business use include local technology requirements or other restrictions on special transactions types. Learn more about specific transaction types, below.


‘Tiered’ countries recognize Qualified Electronic Signature (QES, or the locally named equivalent) as a distinct type of eSignature. In these countries, a QES has special legal status in the form of presumed authenticity, and may be legally required for a few, specific transaction types. In spite of this, a non-QES eSignature can still be submitted as evidence in court even in Tiered countries, so long as the party presenting it has sufficient evidence to prove that it is valid. Countries imposing QES standards often struggle to promote electronic business transactions, especially across country borders. ‘Open’ countries have no such technology requirements or eSignature types that receive special legal status.
