As Sri Lankan businesses accelerate toward digital transformation, the need for secure, legally compliant electronic signature solutions has never been more critical. The Electronic Transactions Act No. 19 of 2006, amended by Act No. 25 of 2017, forms the regulatory foundation for validating electronic contracts and records in the country.

Evia Sign, a trusted eSignature platform, is engineered to fully meet these legal requirements—providing organizations with secure, authenticated, and legally enforceable digital transactions.

This guide breaks down exactly how Evia Sign complies with Sri Lanka’s legal framework while delivering superior security, transparency, and efficiency.

Understanding the Electronic Transactions Act of Sri Lanka

The ETA gives legal validity to electronic signatures, electronic records, and digital contracts. Its core principles include:

1. Technology Neutrality

The ETA does not recommend or limit any specific digital signature technology. Businesses are free to use secure platforms like Evia Sign without restriction.

2. Legal Validity of Electronic Signatures

A digital signature is legally binding when:

• The signer’s identity can be verified
• The signer’s intent to approve the document is clear
• The method used is reliable and secure

3. Scope and Limitations

Almost all everyday business agreements can be signed electronically, except:

• Wills and trusts
• Property transfers and mortgages
• Documents requiring notarization

Digital contracts are treated with the same legal weight as handwritten ones when authenticity and reliability are ensured.
