Compliance Overview

• Baseline use: Commercial agreements where parties accept electronic execution. Thai law recognizes electronic signatures; practical enforceability depends on having reliable evidence for the transaction and scenario.
• Evidence & reliability: OTP re‑auth + explicit intent + a complete audit trail (times, IP/user agent, document hash). ETDA guidance commonly frames e‑signature strength on a risk basis (from simple methods like OTP to certificate‑based digital signatures).
• Higher assurance: For higher‑risk or regulated workflows, use certificate‑based digital signatures (PKI) and trusted timestamping (TSA) where appropriate; some sectors/counterparties may prefer a local certificate provider.
• Data protection: Handle personal data in line with Thailand’s PDPA (lawful basis/consent, security, retention, and data subject rights).

• Baseline use: Business contracts where parties accept electronic execution and you retain strong evidence (OTP re‑auth, audit trail, document hash).
• Higher assurance: For government/regulated workflows, a certificate‑based digital signature (DSC) is commonly used; SecuSign’s roadmap supports “bring your own certificate” style signing.
• Recommended settings: OTP required + explicit consent + keep ledger PDF + enable PAdES/PKI + TSA where available.

• Baseline use: Electronic signatures can be equivalent to handwritten signatures when a reliable procedure is used and integrity is maintained.
• Recommended settings: OTP required + clear intent (“Sign” action) + audit trail export for evidentiary use.

• Baseline use: Validity depends on meeting statutory requirements (attribution, integrity, and control over the signature creation data).
• Certified e‑signatures: For higher‑risk or specific regulated contexts, electronic signatures secured by an electronic certificate issued by a recognized provider (PSrE) may be required.
• Roadmap: Add PSrE / electronic‑certificate integration option for Indonesia‑focused deployments.

• Baseline use: Electronic transactions are broadly recognized; keep strong evidence and reproducible records.
• Trust services: Decree 23/2025 regulates trust services and signature service providers; foreign e-signature recognition is being implemented under the post-2024 framework.
• Recommended settings: Enable PAdES/PKI + TSA for higher assurance; consider local trust service alignment for regulated sectors.

• Baseline use: ESIGN generally prevents denying legal effect to a signature/contract solely because it is in electronic form, when parties choose to transact electronically.
• Consumer consent: In many consumer contexts, ESIGN requires clear disclosures and affirmative consent to receive required records electronically; keep records that are accurate and reproducible.
• State variation: UETA (or state equivalents) governs many state-law transactions; exclusions and requirements can vary by state and document type.
• Recommended settings: OTP required + explicit intent (“Sign” action) + exportable ledger; enable PAdES/PKI + TSA for higher assurance where available.

Note: ESIGN contains exclusions for certain categories of records (for example, some court/probate/family law records, product recall notices, hazardous materials papers, and some notices).

• Baseline use: Provinces and territories have enacted electronic commerce / electronic transactions laws (many modeled on the Uniform Electronic Commerce Act) that support legal recognition of electronic records and signatures for common commercial agreements.
• Privacy: PIPEDA applies to many private-sector organizations handling personal information in commercial activities (with provincial privacy laws also relevant in several provinces).
• Higher assurance: Some workflows (especially public sector / regulated) may refer to “secure electronic signatures” (typically PKI-based digital signatures) under federal or program-specific rules.
• Recommended settings: OTP required + explicit intent + keep ledger PDF; for higher assurance enable PAdES/PKI + TSA where available, and consider local “secure e-signature” expectations per use-case.
