FAQ
Do I have to come in person to sign?
Yes — signing must take place in front of the notary. Alternatively use our mobile dispatch to have a notary travel to your home, hospital or office.
Is the notarial certificate in English?
Every notarial certificate is bilingual TH/EN by default. CN/JP/KR/DE/FR/ES/AR/RU add-ons available on request.
How is a Thai notary different from a Thai district officer (Amphoe)?
The Amphoe certifies copies only for domestic use inside Thailand. A notary produces a certificate accepted overseas and it is the required first step before the MFA / Apostille / destination-embassy chain.
Payment methods?
Thai bank transfer, PromptPay, credit card, PayPal — THB and major foreign currencies.
Does the notary have to be specially registered?
Only lawyers registered as Notarial Services Attorneys with the Lawyers Council of Thailand may notarise. NYC Legal has six such attorneys on staff.
What do I need to bring?
An unexpired national ID or passport, plus the original document to be notarised. For contracts, send the file to us in advance so our legal team can pre-review it.
How much and how fast?
THB 1,500–2,500 · 1–3 hours at our office (by appointment) · same-day express available (+50%).
What happens after notarisation?
Most documents next go to the Thai MFA for the Apostille (in force 14 Feb 2026) or destination-embassy legalisation. We handle the full downstream chain end-to-end.
