Is an Electronic Signature Legally Valid in Indonesia? (2026)

Yes. An electronic signature is legally valid in Indonesia. Indonesia is not part of the EU, so it does not use eIDAS. Its main law is the Electronic Information and Transactions Law, known as the EIT Law, supported by a government regulation on electronic systems and transactions. The law splits electronic signatures into certified and uncertified types, and a certified signature from a recognised Indonesian provider carries the strongest legal effect. This is general information, not legal advice. The rules and standards change, so confirm the current position before relying on any point below. ## The law that governs e-signatures in Indonesia The core rule is Law No. 11 of 2008 on Electronic Information and Transactions, amended by Law No. 19 of 2016 and later by Law No. 1 of 2024. It provides that electronic signatures have legal force and effect, subject to meeting the conditions in the law. Government Regulation No. 71 of 2019 on the Operation of Electronic Systems and Transactions adds detail, including the split between certified and uncertified electronic signatures. <!-- [VERIFY] the exact articles of the EIT Law and Government Regulation No. 71 of 2019 and the effect of Law No. 1 of 2024 before citing specific articles --> For a signature to carry full legal effect under the law, it must meet conditions such as being linked only to the signatory, being under the signatory's control at signing, and allowing any later change to be detected. ## The two main types of signature Indonesian law draws a clear line. - Certified electronic signature. Created using a certificate issued by an Indonesian electronic certification provider (Penyelenggara Sertifikasi Elektronik, or PSrE) recognised by the government. This type carries the strongest legal standing.

• Uncertified electronic signature. Made without a recognised Indonesian certificate, for example through a foreign or basic signing tool. It can still be valid, but it carries less automatic weight and more may need to be proven. ## When you need a certified signature For many private contracts an uncertified electronic signature is accepted when the parties agree and the conditions in the law are met. A certified signature from a recognised Indonesian provider is the safest choice where you want the strongest legal standing, where a public body or regulated process requires it, or where the value or sensitivity of the deal justifies strong identity proof. ## What you usually need extra care with Some acts in Indonesia still need a specific form, a notary, or registration that an ordinary electronic signature does not replace. The EIT Law itself also carves out some documents. These can include: - Documents that by law must be made in a notarial deed.
• Certain letters and documents that require a specific form under other statutes.
• Some land and registration-related documents. <!-- [VERIFY] the current list of documents excluded under the EIT Law or requiring a notarial deed in Indonesia before relying on it --> ## Making an electronic signature stand up in Indonesia Even an accepted uncertified signature should be easy to prove. Good practice includes: - Recording identity, intent to sign, and consent to sign electronically.
• Keeping an audit trail of who signed, when, from where, and which version.
• Using a certified signature from a recognised Indonesian provider where the strongest standing or a regulated process requires it.
• Storing the final signed file so later tampering would be detectable. The certified route gives the strongest footing; an uncertified signature works when the parties clearly accept it and the legal conditions are met. ## Keeping signed contracts in one place An electronic signature is only the last step. Before it, a contract in Indonesia has to be drafted, reviewed for risk, checked against local form and signing rules, and then tracked through its life so renewal dates and obligations are not missed. When that work sits in email, Word files and spreadsheets, the signed PDF often becomes the only record anyone can find later.

The point worth keeping is that signed contracts are easier to govern when the document, its signing evidence and its key dates stay together.
