Thai Notarial Services Attorney notarizing a signed document

How to choose a notarial services attorney in Thailand

Quick answer

Thailand has no common-law notary public. The equivalent role is a notarial services attorney who has completed the course and is registered with the Lawyers Council of Thailand under royal patronage. Verifiable criteria: check the licence and notarial registration number, confirm the signer witnesses the signature in person, and establish whether the receiving authority also requires legalisation by the Department of Consular Affairs or the destination embassy.

The sequence published by the authorities

  1. Confirm with the receiving authority which document, which language, and which layers of certification it requires.
  2. Collect originals certified by the issuing office, including every page that carries an entry.
  3. Reconcile names, dates of birth and document numbers across all documents before translation starts.
  4. Translate and have the responsible person sign the certification in the format the destination requires.
  5. File in the order published by the authority and keep each filing receipt so status can be traced.

Facts by document type and responsible authority

Wills and estates

Cross-border estate matters usually require the court order appointing the administrator plus a finality certificate, then translation and legalisation in the destination’s order.

Overseas property documents

To deal with property abroad from Thailand, a power of attorney is usually signature-certified, then legalised by the Department of Consular Affairs and the destination embassy; the POA form must be the receiving jurisdiction’s own template.
