Will a Thai Notary draft an English Affidavit for me?

Notary Public

Short answer to "Will a Thai Notary draft an English Affidavit for me?" — You must sign in front of the attorney with your original passport; the attorney affixes the notarial seal, signature, register number and date so the document is accepted abroad. The notarised document remains valid indefinitely, but consulates and banks abroad usually accept it only within 3–6 months of issuance. Send a photo of your document to LINE @Thainotary and we'll quote and schedule within 15 minutes.
