Law No. 11/2008 (amended 2016)
Indonesia's e-signature framework
Indonesia regulates electronic signatures through Law No. 11 of 2008 on Electronic Information and Transactions (ITE Law), as amended by Law No. 19 of 2016 and subsequent regulations. The framework distinguishes between uncertified electronic signatures (which have limited evidentiary weight) and certified electronic signatures verified by a Penyelenggara Sertifikasi Elektronik (PSrE) — an Electronic Certification Provider licensed by the Ministry of Communication and Digital (KOMDIGI).

Certified vs uncertified electronic signatures
Indonesia's framework creates a clear distinction: uncertified signatures are admissible as evidence but carry low weight; certified signatures (PSrE-verified) carry a legal presumption of validity.
| Uncertified e-Signature | Certified e-Signature (PSrE) | |
|---|---|---|
| Legal basis | ITE Law Article 11(1): admissible as evidence | ITE Law Article 11(2): legal presumption of validity |
| Provider | Any electronic method | Must use a PSrE licensed by KOMDIGI |
| Identity verification | Not required | Required — eKYC using KTP, passport, or biometric verification |
| Evidence weight | Treated as starting evidence; rebuttable | Strong presumption; difficult to challenge |
| Typical use | Low-risk acknowledgements, internal approvals | Commercial contracts, employment agreements, government filings |
| Cross-border | Low recognition outside Indonesia | Increasingly recognised in ASEAN mutual recognition discussions |
What PSrE certification means
A PSrE is an electronic certification provider licensed by KOMDIGI to issue certified electronic signatures. The PSrE framework ensures that signatures meet identity, integrity, and non-repudiation standards.
PSrE providers must obtain a licence from KOMDIGI (formerly Kominfo). The licence covers identity verification processes, cryptographic standards, certificate management, and audit obligations.
Before issuing a certified signature, the PSrE must verify the signer's identity through eKYC — typically using KTP (national ID), passport, or biometric verification. This is a core requirement for the legal presumption under ITE Law Article 11(2).
PSrE signatures use PKI-based asymmetric cryptography. Each signature is backed by a digital certificate that includes the signer's verified identity data, certificate validity period, and the PSrE's licensing information.
PSrE signatures include trusted timestamps and generate audit trails that record the signing event, IP address, device information, and verification steps. This evidence package is critical for enforceability.

Foreign companies signing with Indonesian counterparties
Foreign companies are not required to use a PSrE, but contracts signed without PSrE certification may face evidentiary challenges in Indonesian courts. For high-value or dispute-prone contracts, using a PSrE-certified signature on the Indonesian side is strongly recommended.
PDP Law (2022)
Indonesia's Personal Data Protection Law (Law No. 27 of 2022) is now in force. Signing platforms that process Indonesian personal data must comply with consent, purpose limitation, and data transfer requirements. Cross-border data transfer requires specific safeguards.
Language requirements
While Indonesian law does not universally mandate Bahasa Indonesia for all commercial contracts, government contracts and certain regulated filings require Bahasa Indonesia. A bilingual (English/Bahasa) approach is safest for cross-border agreements.
Notarial and land transactions
Certain documents — particularly those involving land rights (HGB, hak milik) and notarial deeds — require physical notarisation and cannot be fully executed electronically. Electronic signatures can be used for preliminary agreements but the final registered document must go through a notary (PPAT).
ITE Law articles that govern electronic signatures
The ITE Law establishes the legal framework through specific articles that distinguish between uncertified and certified electronic signatures.
Article 11(1): Uncertified signatures
Article 11(1) provides that an electronic signature has legal effect and is admissible as evidence in court. However, uncertified signatures do not carry a presumption of validity — the burden of proof rests on the party relying on the signature.
Article 11(2): Certified signatures
Article 11(2) states that a certified electronic signature — one verified by a licensed PSrE — has the same legal effect as a handwritten signature. This creates a strong legal presumption that shifts the burden of proof to the challenging party.
Article 12: Electronic certificate requirements
Article 12 defines electronic certificates as electronic records that identify the certificate holder and are signed by a certification service provider. PSrE-issued certificates must meet cryptographic standards and identity verification requirements set by KOMDIGI.
Government Regulation 71/2019
GR 71/2019 implements the ITE Law and classifies electronic systems into two tiers: public electronic systems (operated by government) and private electronic systems (operated by private entities). PSrE providers must register as private electronic system operators.
Licensed PSrE providers in Indonesia
Only KOMDIGI-licensed PSrE providers can issue certified electronic signatures with the Article 11(2) legal presumption.
PrivyID
PrivyID is one of Indonesia's most widely used PSrE providers, serving both individual and corporate signers. The platform offers eKYC verification using KTP (national ID) and biometric checks, followed by PKI-based signature issuance.
PERURI (Perum Peruri)
The State Mint (PERURI) operates a PSrE service integrated with government identity systems. PERURI signatures are commonly used for government filings, state-owned enterprise contracts, and regulated industry transactions.
International platform integration
Global e-signature platforms can operate in Indonesia by partnering with a local PSrE. The international platform handles the document workflow and user experience, while the PSrE handles identity verification and cryptographic signature issuance. This model preserves the Article 11(2) legal presumption.
Indonesian e-signature implementation checklist for employers
Indonesian employers implementing electronic signing must ensure PSrE compliance.
Choose a PSrE-certified provider
Only signatures from PSrE-certified providers have legal effect under Indonesian law. Verify your signing provider PSrE certification on the Ministry of Communication and Information (Kominfo) website. Non-certified signatures are admissible as evidence but carry lower weight.
Configure Sistem ID
Indonesian citizens can use Sistem ID for identity verification, similar to Singpass in Singapore. Signing platforms that integrate with Sistem ID offer better signer experience and stronger identity proofing.
Language requirements
Employment contracts in Indonesia should be in Bahasa Indonesia (Law No. 24 of 2009). If a bilingual contract is needed, the Bahasa version prevails. Ensure your signing platform supports Unicode in document content and signer names.
Data localisation under PDP Law
Indonesia PDP Law (effective 2024) requires personal data to be stored in Indonesia under certain conditions. Verify that your signing platform offers Indonesian data residency or that data transfer mechanisms are in place for cross-border signing data.
Common questions about Indonesia e-signatures
Yes. The ITE Law recognises both uncertified and certified electronic signatures. Uncertified signatures are admissible as evidence but carry lower weight. Certified signatures (PSrE-verified) carry a legal presumption of validity equivalent to handwritten signatures.
How eSign.AI supports PSrE-compliant signing in Indonesia
eSign.AI supports Indonesian signing workflows through its confirmed Vinotek integration. The deployment must verify Vinotek's role, the applicable registered PSrE service, certificate product, and identity-verification process.
PSrE-certified signatures
eSign.AI integrates with Vinotek for Indonesian signing workflows. Before describing a signature as certified, verify the registered PSrE involved, certificate chain, signer identity process, and current Komdigi status for the selected service.
Bahasa Indonesia support
The signing UI is available in Bahasa Indonesia. Contract content fully supports Indonesian diacritics and formatting. The audit trail is generated in Bahasa and English, supporting both local compliance and international employer needs.
PDP Law compliance
Indonesia PDP Law requires personal data to be processed with consent and stored with adequate protection. eSign.AI captures data processing consent as part of the signing flow, offers data residency options for Indonesian signing data, and provides data subject access mechanisms for compliance with PDP Articles 5-7.
Identity integration roadmap
Identity options in Indonesia continue to evolve. eSign.AI's current confirmed local integration is Vinotek; any national digital-identity connection or additional PSrE integration should be published only after the production interface and provider status are confirmed.
