eSignature Legality in Sri Lanka

E-Signature Legality Summary

This guide explains the electronic-signature framework in Sri Lanka, including the governing laws, legal effect, accepted signature methods, validity requirements, exclusions and practical business uses.

Applicable Laws

Electronic Transactions Act No. 19 of 2006, as amended by Act No. 25 of 2017

Legal Status

Electronic records and signatures receive legal recognition in Sri Lanka under Electronic Transactions Act No. 19 of 2006, as amended by Act No. 25 of 2017. The signing process must also satisfy every document-specific rule on identity, evidence, delivery, retention, witnessing, notarization, registration or filing.

Regulatory Authority

The Information and Communication Technology Agency (ICTA), Sri Lanka is the principal government body responsible for promoting implementation of the applicable Act.

Legal Recognition (Effect)

Sri Lanka recognizes an Electronic Signature (SES) and a Reliable Electronic Signature. An Electronic Signature is any letter, number, symbol, image, character, or combination in electronic form attached to, embedded in, or logically associated with an electronic document for verification or approval and to establish authenticity, integrity, or both. It is reliable if its creation data is uniquely linked to and under the sole control of the signatory and any post-signing alteration to the signature or, where integrity is the purpose, the signed information is detectable.

Accepted Types of Electronic Signatures

RES: Reliable Electronic Signature

The official website currently does not recognize foreign CAs; signatures include two types, SES and QES

Electronic signature: means any letter, number, symbol, image, character, or any combination thereof in electronic form, attached to, incorporated in, or logically associated with an electronic document for the purpose of verifying and/or approving that electronic document, thereby establishing the authenticity, integrity, or both, of the electronic document.

Definition of "reliable electronic signature": the Act sets out the criteria for determining whether an electronic signature is "reliable," mainly including:

the signature creation data is, at the time of signing, uniquely linked to the signatory;

the signature creation data is, at the time of signing, under the control of the signatory and no other person;

any tampering with the electronic signature after signing can be detected;

if the purpose of the signature is to prove the integrity of the signed information, any tampering with the information after that can be detected.

Electronic Signatures (SES), particularly ordinary and Advanced Electronic Signatures (AES), are unavailable or subject to additional requirements for marriage and divorce agreements, wills, adoption documents, instruments creating or transferring real-property rights, and documents that law requires to be completed in a specified written form before a notary or comparable authority.

Legal Requirements for Electronic Signatures

the signature creation data is, at the time of signing, uniquely linked to the signatory;

the signature creation data is, at the time of signing, under the control of the signatory and no other person;

any tampering with the electronic signature after signing can be detected;

Limitations and Exceptions

1. Transactions related to immovable property (real property)

Details: contracts creating, transferring or disposing of immovable property (such as land and houses).

Legal provision: Section 4 of the Act.

Reason: real estate transactions are legal acts involving significant property rights and usually require strict registration and public notice procedures. To ensure clear rights and prevent fraud, Sri Lankan law requires these transactions to be conducted in written document form and to be physically registered with the relevant registration authority. Electronic form is currently not accepted.

2. Wills, will amendment documents and testamentary trusts

Details: legal documents making, amending or revoking a will.

Legal provision: Section 5 of the Act.

Reason: a will is an act taking effect upon death; when it takes effect, the testator can no longer verify it. Therefore, the law imposes extremely strict formal requirements on wills (such as personal signature, presence of witnesses, etc.) to ensure the authenticity of the final wishes and prevent tampering. Electronic form is currently considered unable to fully satisfy such formal requirements.

3. Negotiable instruments

Details: bills of exchange, promissory notes, cheques and other negotiable instruments.

Legal provision: Section 4 of the Act.

Reason: the core characteristic of negotiable instruments is transferability, and holding the instrument itself usually means owning the rights. The "possession" of a physical instrument has special legal significance. Digitizing these instruments requires establishing an entirely new legal framework (such as an Electronic Instruments Act), which the Act does not cover.

4. Powers of attorney

Details: documents granting agency authority.

Legal provision: pursuant to the exemption clause of Section 1 of the Act, and the provisions of Sri Lanka's Powers of Attorney Ordinance.

Reason: a power of attorney involves a significant relationship of personal trust, whereby the grantor grants another person the right to handle their own affairs. The law requires strict formalities, usually requiring written form and authentication through specific procedures, to ensure that the authorization is the true and voluntary intention of the grantor.

5. Documents related to court proceedings

Details: litigation documents, affidavits, pleadings and other documents required to be submitted to the court.

Legal provision: the Act authorizes the court or relevant laws to make provisions on this.

Reason: judicial proceedings have solemnity and mandatory nature, and document submission must comply with the specific rules of the court. Although the global trend is to promote electronic court systems, this requires the Supreme Court or Parliament to authorize it through a dedicated Judicial Procedure Act or court rules, rather than being generalized by the Electronic Transactions Act. In Sri Lanka, this part is being gradually advanced, but not all court documents are allowed to be submitted electronically.

6. Other areas exempted by the Minister through the Gazette

The Act grants the Cabinet Minister (usually the Minister of Finance or the Minister of Technology and Innovation) the power to publish a notice in the Government Gazette declaring other types of transactions or documents to which this Law does not apply. This provides flexibility for the law to adapt to future developments.

Industry Applications and Typical Use Cases

Supported in most scenarios

Electronic signatures support commercial contracts, sales and procurement, employment documentation, internal approvals and customer onboarding when the governing document and sector rules are satisfied.

For regulated or cross-border workflows, record the governing law, required assurance level, signer-authentication method, evidence package, retention period and receiving-party requirements before launch.
