An NRI in Thailand currently authenticates a Power of Attorney for Indian property matters through legalization at the Thai Ministry of Foreign Affairs, followed by attestation from the Embassy of India, Bangkok -- since Thailand is not yet a Hague Apostille Convention member, though it is actively moving toward accession.
Thailand's pending Apostille accession, and the current process
Thailand is not yet a Hague Apostille Convention member. Thailand joined the Hague Conference on
Private International Law in March 2021, and the Thai Cabinet approved accession in principle around 9
December 2025 -- but as of this writing no instrument of accession has been deposited, so the older
legalization chain remains in effect. A document such as a Power of Attorney is typically certified by a
licensed Thai lawyer acting as a Notarial Services Attorney, then legalized by the Thai Ministry of
Foreign Affairs' Legalization Division in Bangkok, and then attested by the Embassy of India, Bangkok.
The current process, step by step
- Certification before a Thai Notarial Services Attorney.
- Legalization at the Thai Ministry of Foreign Affairs, Legalization Division,
Bangkok.
- Attestation by the Embassy of India, Bangkok, commonly through the India Visa
& Consular Application Centre (ICAC) -- the POA generally must be signed in person before a
consular officer. The ICAC cites a processing time of generally 3-5 business days; this platform
could not confirm current fees from a primary source.
- Send the attested original to India.
Registration in India, and watching for the Apostille transition
The process above does not complete matters on the Indian side. Under Section 17 of the Registration
Act, 1908, the POA itself still needs to be adjudicated for stamp duty and registered in India before the
transaction it authorizes can be completed. Given how actively Thailand's Apostille accession is
progressing, confirm the current authentication requirement close to the transaction date.
Common mistakes people connected to Thailand make with this process:
- Assuming Thailand already offers a single-step apostille, when it remains a non-Hague-member
country as of this writing.
- Skipping the Thai Ministry of Foreign Affairs legalization step before seeking Embassy
attestation.
- Using a General POA when a Specific POA would have been the safer, more easily evaluated
choice.
Is Thailand a Hague Apostille Convention member?
Not yet, as of this writing -- Thailand has approved accession in principle but has not yet deposited
its instrument of accession, so the older legalization chain still applies.
What is the current process to authenticate a Power of Attorney from Thailand for use in India?
Certification before a Thai Notarial Services Attorney, legalization at the Thai Ministry of Foreign
Affairs' Legalization Division, and attestation by the Embassy of India, Bangkok (commonly via the
ICAC).
Does the POA still need to be registered in India after this process?
Yes. Attestation makes the document usable in India; separately, under Section 17 of the Registration
Act, 1908, the POA itself still needs to be adjudicated for stamp duty and registered in India before the
transaction it authorizes can be completed.
