Certification of the Existence of Documents

Litigation evidence: when you must prove that a document, image, or event existed before a complaint was filed — copyright infringement on websites, defamatory posts, brand/logo appearance before trademark registration, delivery of goods, the state of a property before a lease, and preservation of LINE/WhatsApp/email messages for evidence.

Intellectual property: designers, artists, writers, composers, and software developers use this service to prove ‘the date a work came into being’ before publication or infringement — a critical element in copyright proof under Thai law and the Berne Convention.

Cross-border business: preserving evidence before international arbitration (ICC, SIAC, HKIAC) — the state of contract documents, shipment evidence, goods condition on delivery, and financial documents confirming payment.

Our attorneys certify in a form designed for court proof: (1) physically inspect the original document/item, (2) capture photographs and video with timestamp and GPS, (3) read and inspect the document's content in full, (4) log the act in the Notarial Register, and (5) issue a certificate referencing the attorney's registration number with the Notary seal.

We archive document copies, photographs, video, and full metadata in secure cloud storage for 15 years, so that clients can call the file back for use as evidence in court at any time, complete with a chain-of-custody record.

Digital-era infringement often happens on websites, social media, apps, and email — where evidence can disappear in hours. Our service covers certifying the existence of URLs, screens, conversations, messages, and digital files on a specific date and time. The attorney uses an office computer, captures the screen with cryptographic-hash-enabled software, archives the source HTML, and records the relevant IP and DNS lookup.

This evidence is used in online copyright, social-media defamation, and electronic fraud cases — accepted in Thai courts and many foreign courts, especially when paired with cryptographic hashing that proves the file has not been altered since certification.

A Thai designer discovered her work copied on a foreign website — before issuing a DMCA Takedown, our team certified the infringing page, archived screenshots and the hashed HTML within 2 hours of discovery, and the client recovered USD 15,000 in compensation from the foreign platform.

A Thai exporter shipping to Europe faced a dispute over product condition — we visited the port before shipment, inspected the container and goods, issued a certification with photos, and the evidence won the SIAC arbitration with full payment recovered.

A composer wanted to record the date a song was completed — we certified the original .wav file and the score sheet on the day the composer visited our office. The evidence supported copyright registration with the Department of Intellectual Property and was decisive when the song was later used without permission.

Service covers all 77 provinces. For emergency evidence preservation, our team is on-call 24 hours in Bangkok and surrounding provinces, and can travel up-country — Phuket, Chonburi, Rayong, Chiang Mai, Hat Yai, and EEC industrial cities — within 6–12 hours for time-sensitive evidence.

Meetings at major Bangkok malls and coworking cafés are also possible — CentralWorld, Siam Paragon, ICONSIAM, EmQuartier, Central Embassy, Thonglor, Ekkamai, and locations near every BTS/MRT station — for clients who must preserve evidence on short notice.
