TILAKA — CERTIFIED ELECTRONIC SIGNATURES
Electronic Signatures for Notaries & Land Deed Officials: Legally Valid, Verified, and Integrated
Tilaka provides certified electronic signatures issued through a Certificate Authority (PSrE) recognized by Indonesia's Ministry of Communication and Digital Affairs, built for notaries, land deed officials (PPAT), and legal practitioners. Every signature is bound to an identity verified against national population data, meets the requirements of the Electronic Information and Transactions Law (UU ITE) and Government Regulation 71/2019, and cryptographically protects document integrity.
Notarial practice in Indonesia increasingly runs on electronic documents. Clients send contract drafts by email, banks expect covernotes within hours, and correspondence with institutions has gone digital. Yet a scanned wet-ink signature offers no guarantee of document integrity or signer identity — it creates exactly the kind of evidentiary gap a legal professional exists to prevent.
Certified electronic signatures address this directly. Article 11 of UU ITE affirms that an electronic signature has lawful legal force and legal effect provided it meets specific requirements, and Article 60 of Government Regulation 71/2019 distinguishes certified electronic signatures — created using the services of a certified Indonesian Certificate Authority (PSrE) — from uncertified ones. For a profession built on legal certainty, this distinction is not a technicality; it is the foundation of evidentiary strength.
One point deserves honesty: for authentic deeds, Article 5(4) of UU ITE excludes documents that by law must be made in notarial deed form, and the Notary Law still prescribes the conventional procedure for executing deeds. But surrounding every deed is a wide ecosystem of documents — covernotes, private agreements, certain powers of attorney, official correspondence, internal office paperwork — that can lawfully and far more safely be signed with certified electronic signatures. That is where Tilaka helps notarial offices move faster without compromising compliance.
The Real Risks Behind Digital Documents Without Certified Signatures
Scanned signatures are easily repudiated
A signature image pasted into a PDF proves neither who signed nor when. In a dispute, the opposing party can readily deny its authenticity.
Document integrity is unprotected
A digital document without a cryptographic seal can be altered after signing without leaving a trace — directly at odds with the legal certainty the notarial profession must provide.
Signer identity is never verified
Emailing a document to a client does not guarantee the person signing is the rightful party. Without identity verification, the validity requirements of UU ITE Article 11 are not met.
Back-and-forth handling slows service
Waiting for clients to visit the office or courier physical documents delays covernotes, agreements, and administration — while banks and corporate clients demand speed.
How Tilaka Supports Legal Document Workflows
Certificates from a government-recognized CA
Signatures are issued against electronic certificates from a PSrE recognized by the Ministry of Communication and Digital Affairs, meeting the criteria for certified electronic signatures under GR 71/2019 Article 60.
Identity verified against population data
Signers complete e-KYC with ID card (KTP) matching and facial biometric verification, binding the signature exclusively to its owner — as required by UU ITE Article 11.
Cryptographically protected integrity
Each document is sealed with a cryptographic hash; any alteration after signing is detectable. Authenticity can be verified by any party at any time.
Complete audit trail
Signing time, verified identity, and process history are recorded as electronic evidence supporting admissibility under UU ITE Article 5(1) and 5(2).
Integration into office workflows
Use the signing application directly or integrate via API with the document management systems of notarial offices, PPAT practices, or law firms — including sequential multi-party signing.
Tilaka is used by financial institutions and corporations across Indonesia for high-volume document signing that demands legal validity and rigorous identity verification.
How It Works: From Registration to Signed Document
Register and verify identity
Each signer registers once with their KTP and facial biometric verification matched against national population data. Upon successful verification, the PSrE issues an electronic certificate in the signer's name.
Upload and prepare documents
Documents — covernotes, agreements, powers of attorney, administrative paperwork — are uploaded through the application or sent automatically from your office system via API. Assign signers and signing order for multi-party documents.
Authorize and sign
Each signer personally authorizes the action — only the certificate holder can apply their signature. The electronic signature is then bound to the document along with a timestamp.
Verify and retain evidence
Any party can verify the final document's authenticity; the audit trail is retained as evidence of the process. The document is ready for distribution to clients, banks, or relevant institutions.
Frequently Asked Questions
Are electronic signatures legally valid in Indonesia?
Yes. Article 11 of UU ITE states that an electronic signature has lawful legal force and effect provided it meets requirements including that the signature-creation data is linked only to the signer and any post-signing alteration is detectable. Certified electronic signatures from a government-recognized PSrE are designed to satisfy these requirements.
Can notarial deeds be signed electronically?
For authentic deeds, Article 5(4) of UU ITE excludes documents that by law must be made in notarial deed form, and the Notary Law still governs conventional deed execution. However, the many documents surrounding notarial practice — covernotes, private agreements, correspondence, administrative documents — can lawfully be signed electronically. We recommend a consultation to map which document types are appropriate to digitize.
What is the difference between certified and uncertified electronic signatures?
GR 71/2019 Article 60 draws the distinction: certified signatures are created using the services of a certified Indonesian PSrE and evidenced by an electronic certificate, while uncertified signatures are created without one. In evidentiary practice, certified signatures provide substantially stronger assurance of identity and integrity.
How strong is the evidence if a dispute reaches court?
Electronic information and documents, including their printouts, are lawful legal evidence under UU ITE Article 5(1) and 5(2). Certified signatures carry an electronic certificate, timestamp, and audit trail that help prove who signed, when, and that the document has not changed since signing.
How is the signer's identity verified?
Through an e-KYC process: KTP data matching and facial biometric verification against national population data before the electronic certificate is issued. Personal data in this process is handled in line with the protection principles of Law 27/2022 (the PDP Law).
What about the cyber notary concept?
The elucidation of Article 15(3) of the Notary Law mentions notaries' authority to certify electronically conducted transactions (cyber notary), but implementation awaits further regulation. Adopting certified electronic signatures today for documents that can already lawfully be digitized is a sensible readiness step in that direction.
