Crypto Wallet Ownership Declaration Certification in Thailand
A crypto wallet declaration is used to show a bank or platform that you own a wallet and explain the source of funds. A notary certifies that you signed in person, not that the wallet is yours or that the funds are clean. Ownership is proven separately by signing a message from the wallet or showing transactions.
Certification scope and key checks
State the wallet address and the transaction period clearly.
Attach supporting evidence such as transaction screenshots or reports from SEC-supervised platforms.
If the recipient needs real proof of ownership, prepare a signed message from the wallet separately.
Documents to prepare
- Declarant's ID/passport
- Wallet address and transaction evidence
- Recipient's requirements
Procedure for this document
- Check what the recipient needs
- Draft the declaration
- Sign before a notary
- Attach evidence and translate if needed
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
- Does the notary verify wallet ownership?
- No; only the signature.
- How is ownership proven?
- By signing a message from the wallet or showing the transaction history.
- Is crypto legal in Thailand?
- Trading on SEC-supervised platforms is permitted, but crypto is not legal tender.
- 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.
