Indonesia Electronic Signatures: PSrE Requirements

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.

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.

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.

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).

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) 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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.
