Non-Disclosure Agreement (NDA) Certification in Thailand
An NDA binds the parties once signed; notarisation is generally not required. Use it only when a counterparty or foreign body asks for certified signatures or the NDA will be evidence abroad.
Certification scope and key checks
Define confidential information, term, exclusions and governing law clearly.
A notary confirms who signed, not whether the terms are enforceable.
For Thai–foreign parties, use a bilingual version and state the governing language.
Documents to prepare
- Final agreement
- Identity and signing authority
- Recipient requirements, if any
Procedure for this document
- Confirm certification is actually required
- Sign before a notary if so
- Translate if needed
- Each party keeps an original
Overseas use: confirm the recipient’s route
Notarization is not required for every public record, and some uses need no onward legalisation. Confirm whether the recipient needs an original, copy, translation or specific certification before arranging MFA and embassy steps where applicable.
Thailand deposited its accession on 30 June 2026. The Apostille Convention is scheduled to enter into force for Thailand on 28 February 2027. Do not assume Thai Apostilles are available before then. Even after entry into force, document scope and treaty relations with the destination must be checked.
Questions before booking
- Is an unnotarised NDA valid?
- Yes between the parties; notarisation evidences signatures.
- Can it be signed electronically?
- Often yes; check the recipient accepts it.
- Will the notary review the terms?
- Contract review is legal work, separate from certification.
- Are MFA and embassy legalisation always needed?
- No. Ask the recipient to confirm the certification, language and onward steps. Notarization, translation and legalisation are distinct; do not perform every step automatically.
- How are fees and timing assessed?
- After reviewing the form, copies, signers, language and onward steps, we provide a quote and indicative schedule before work. Authority queues and outcomes are not guaranteed.
- What should I send before booking?
- Send the record type, destination country, receiving authority and its checklist through a direct contact channel. Redact personal information unnecessary for the initial enquiry.
