Notary Cost in Chiang Mai (2026)
Quick Answer
Partially verifiedIn Chiang Mai, notary-style document certification is usually handled by Thai lawyers who are registered as Notarial Services Attorneys. Publicly posted Chiang Mai prices are not easy to verify from official provider websites, so a realistic working budget is around THB 500-1,500 per signature/document for straightforward notarisation, with more complex affidavit, translation, or multi-document work often landing around THB 1,500-5,000 in total. If the document will be used overseas, you may also need separate legalisation fees at the Thai Ministry of Foreign Affairs.
Overview
Chiang Mai does not have a notary public system identical to some common-law countries; instead, notarisation-like services are typically provided by licensed Thai lawyers who hold the Notarial Services Attorney qualification recognised by the Lawyers Council of Thailand. In practice, people in Chiang Mai usually seek these services for powers of attorney, passport copies, company documents, declarations, consent letters, visa paperwork, and signatures intended for foreign embassies, banks, or overseas authorities. Pricing is often not published in a transparent list, so the local market commonly works on a per-signature, per-document, or small-package basis rather than a formal hourly tariff. For simple certification of identity documents or witnessing a signature, fees are commonly modest by business-service standards, while bespoke drafting, bilingual paperwork, urgent appointments, and document sets for use abroad cost more. Where a translation is required, it is normally billed separately from the notarial act. If the receiving country requires further authentication, a Chiang Mai lawyer's notarisation may still need legalisation through the Thai Ministry of Foreign Affairs, which adds both fees and processing time. Because prices vary by complexity and provider, asking for a written quote per document set is the safest way to compare options.
What It Costs
| Item | Cost | Evidence |
|---|---|---|
| Simple notarisation or signature witnessing(per document) Estimated range based on typical market rates charged by Thai law firms for straightforward notarial services in major cities, including Chiang Mai, where pricing is usually quoted per document or signature rather than published on official schedules. Estimated range | ~THB 500 – THB 1,500 | Estimated range |
| Affidavit or declaration with notarisation(per document) Estimated range based on typical Thai legal-service pricing when drafting plus notarisation are bundled for a standard personal declaration or affidavit. Estimated range | ~THB 1,500 – THB 3,000 | Estimated range |
| Multi-document package for overseas use(per package) Estimated range based on common package pricing for several related documents, copies, and signatures handled together by a notarial services attorney. Estimated range | ~THB 2,500 – THB 5,000 | Estimated range |
| Urgent or out-of-office appointment surcharge(per appointment) Estimated range based on typical business-service call-out or same-day urgency surcharges in Thai legal markets; many providers quote this case by case. Estimated range | ~THB 500 – THB 2,000 | Estimated range |
| Thai MFA legalisation fee after notarisation(per document) The Thai Ministry of Foreign Affairs online legalisation system is the official channel for document legalisation after notarisation. Actual fee depends on service type and current MFA schedule; standard legalisation is commonly referenced at around THB 200 per document, with faster service higher where available.

Simple notarisation is often completed in one appointment if documents are ready; legalisation for overseas use takes longer.
How Fees Work
Usually charged per document, per signature, or as a small package rather than by a strict hourly rate. Drafting, translation, travel, and MFA legalisation are commonly extra.
Factors Affecting Price
- Whether you need simple witnessing only or full drafting of an affidavit, power of attorney, or declaration
- Number of documents, signatures, certified copies, and whether each page must be stamped
- Whether translation, bilingual preparation, or embassy-specific wording is required
- Urgency, same-day turnaround, weekend appointments, or travel to your location
- Whether the document also needs Thai Ministry of Foreign Affairs legalisation or embassy authentication afterwards
Local Context
In Chiang Mai, legal-service quotes are commonly given as all-in figures for simple paperwork, but translation, couriering, and government legalisation are often extra. VAT may or may not be separately stated depending on the provider. Tipping is not standard for legal and notarial work. Costs in Chiang Mai can be a little lower than in central Bangkok, but international-document work can still price similarly if specialist drafting is needed.
