Are Electronic Signatures Legal in Saudi Arabia?

Short answer: yes. Electronic signatures are legally recognized in Saudi Arabia. They carry the same legal weight as a handwritten signature — provided a few conditions are met. Here's exactly what the law says, what's excluded, and how to make sure your e-signatures hold up.

The law behind e-signatures in Saudi Arabia

The Kingdom of Saudi Arabia regulates electronic signatures through the Electronic Transactions Law (نظام التعاملات الإلكترونية), issued by Royal Decree No. M/18 dated 8/3/1428H (corresponding to 2007), together with its implementing regulations.

The law's core principle is functional equivalence: an electronic record, document or signature is not denied legal effect simply because it is electronic. When the requirements of the law are satisfied, an electronic signature has the same legal force as a handwritten signature, and an electronic record satisfies a legal requirement that information be in writing.

This sits squarely within Saudi Arabia's Vision 2030 digital-transformation agenda, which has pushed government and private-sector services toward fully paperless workflows.

What makes an electronic signature valid?

For an e-signature to be reliable under the law, it should generally meet these conditions:

• Uniquely linked to the signer — the signature data is connected to that person and no one else.
• Under the signer's sole control — only the signer could have produced it.
• Verifiable identity — there is a reliable way to confirm who signed.
• Clear intent and consent — the signer meant to sign and agreed to do so electronically.
• Integrity — any change to the document after signing can be detected.

Two tiers: electronic signature vs. certified digital signature

Saudi law distinguishes between a general electronic signature and a certified electronic signature backed by a digital certificate issued under the Kingdom's certification framework. Both can be valid, but a certified signature carries a stronger presumption of reliability and is often expected for higher-value or government-facing transactions.

What can't be signed electronically?

The law carves out exceptions. Certain documents may still require a traditional form, physical attestation, or notarization — for example some personal-status matters (such as marriage and similar family documents) and specific transactions that a regulator designates. Real-estate and certain official deeds can also have their own formalities.
