eSignature legality summary
A written signature is not required for a valid contract unless a statute stipulates otherwise; the ETA confirms a contract is not unenforceable merely for being electronic, and electronic records are admissible under ETA s.21. Sri Lanka is technology-neutral (no required signature technology), though some local parties still prefer conventional execution formalities.
Types of permitted electronic signature
Sri Lanka takes an open, technology-neutral approach — no specific technology (digital certificate or otherwise) is mandated for an enforceable electronic signature. Some dealings with government institutions may carry specific requirements.
Documents that may be signed electronically
Suitable for commercial agreements between corporate entities (NDAs, procurement, sales) and consumer agreements such as retail account opening.
Use with caution / not typically appropriate
In practice, employment contracts often use wet ink for evidentiary ease and labour-department filings; IP filings (National Intellectual Property Office) and company filings (Registrar of Companies) require ink signatures; and some government departments still require handwritten documents.
