What is a Notarial Protest of Instruments and When Is It Required
A Notarial Protest of Instruments is a formal certificate issued by a Notary Public attesting that a negotiable instrument — a bill of exchange, promissory note, cheque, or Letter of Credit — was duly presented for acceptance or payment and was dishonoured by the drawee. Under Thai Civil and Commercial Code sections 960-963 and the Uniform Commercial Code of many jurisdictions, the protest is a statutory precondition before the holder can exercise recourse against endorsers or guarantors. Missing the protest deadline extinguishes those rights automatically. Our NSA team at NAATI Thailand therefore issues a formal protest within 24 hours of notice of dishonour and then routes the certificate through MFA Legalization and Hague Apostille so it is admissible in foreign courts immediately.
Step-by-Step Notarial Protest Process
The workflow begins when the holder notifies us via LINE @NAATI or +66 2 114 3563 within the statutory window (generally one business day from dishonour for inland bills and four days for foreign bills). The holder presents the original instrument, evidence of presentment (such as a bank return slip or drawee's endorsement), and a valid ID to our attorney. The NSA attorney verifies the instrument, re-presents it to the drawee if required, and issues a Notarial Protest Certificate stating the holder, drawer, endorsers, amount, maturity date, presentment date, reason for dishonour, and the statutory protest wording. The certificate is signed, sealed with the red NSA stamp, and produced in parallel Thai-English text. We then process MFA Legalization and Hague Apostille so the protest is admissible abroad without further consularisation.
Instrument Types Eligible for Notarial Protest
Our service covers every category of negotiable instrument recognised under the Thai Civil and Commercial Code and the 1930 Geneva Convention on Bills of Exchange and Promissory Notes: inland and foreign bills of exchange, promissory notes, ordinary and traveller's cheques, Letters of Credit dishonoured by the issuing bank, bank drafts, and banker's acceptances. Beyond Protest for Non-Payment we also issue Protest for Non-Acceptance when a drawee refuses to accept a bill, and Protest for Better Security when the acceptor's financial position deteriorates before maturity. A frequent scenario is an exporter whose foreign buyer refuses payment under an L/C and needs a protest to claim against the confirming bank.
Pricing, Turnaround, and Service Terms
Pricing for Notarial Protest of Instruments starts at THB 5,000 for an inland cheque or bill up to THB 1 million face value and reaches THB 25,000 for a foreign bill or L/C requiring coordination with overseas banks. The fee covers drafting, NSA seal, certificate, and attorney time, but excludes MFA Legalization fees (THB 200-400 per stamp), Hague Apostille fees (THB 800 per stamp), and international courier charges. Standard turnaround is 24 hours to meet statutory deadlines. A Same-Day Emergency Protest desk operates 24/7 including public holidays for cases nearing the deadline. We accept PromptPay, Stripe card payments, and cash. e-Tax invoices are issued, and corporate clients may apply for 7-15 day credit terms.
Dedicated Service for International Trade Clients
Exporters, importers, and financial institutions running cross-border transactions are the core users of our Protest service. Our team has worked with every Thai commercial bank and the Bangkok branches of HSBC, Standard Chartered, MUFG, ANZ, and OCBC, and understands ICC UCP 600 and URC 522 procedures inside out. A recent matter involved protesting a USD 4.2 million L/C dishonoured by an issuing bank in the Middle East, enabling our client to claim successfully against the confirming bank in Singapore. Our consultants speak English, Mandarin, Japanese, Korean, and Vietnamese fluently and coordinate directly with destination-country counsel and your in-house international trade lawyers.
End-to-End MFA Legalization and Hague Apostille
Once the Notarial Protest Certificate is issued we proceed with MFA Legalization at the Department of Consular Affairs on Chaeng Watthana Road (1-3 business days) and then Hague Apostille stamping under the Convention which Thailand acceded to in 2024. The certificate becomes admissible in 125+ member states without further consularisation. For non-member jurisdictions such as UAE, Saudi Arabia, China, and Vietnam we coordinate with the destination embassy in Thailand for the final legalisation step. Every document carries a verification QR code logged in the Lawyers Council registry, minimising the risk of rejection by the destination court.
