When is arbitration preferable to litigation?

Arbitration under the Arbitration Act B.E. 2545 (2002) requires a written arbitration agreement. It is private, allows the parties to appoint arbitrators with sector expertise, and awards are binding and enforceable through the courts. The Thailand Arbitration Center (THAC) is a commonly used institution for commercial disputes seated in Thailand.

Which court hears intellectual property disputes in Thailand?

The Central Intellectual Property and International Trade Court has jurisdiction over IP and international trade matters, with appeals following the routes set out in the governing legislation. Filings are made in Thai, so foreign-language contracts, registration certificates and evidence must be translated and certified in the form the court accepts. Preparing an accurate exhibit bundle early usually matters more to the timetable than any procedural shortcut.

What language rules apply to IP filings in Thailand?

Filings before the Department of Intellectual Property are made in Thai, so foreign-language documents are submitted together with a Thai translation whose accuracy is certified in the manner the regulations require. Corporate documents and powers of attorney executed abroad are commonly required to be notarised and then legalised by the Royal Thai Embassy in the country of execution. For patents, the translation of the claims determines the scope you can enforce, so terminology is fixed against the original rather than paraphrased. Confirm the current document list with the Department before filing, as forms are periodically revised.

Can I file in several countries from Thailand at once?

Yes. Thailand has been a party to the Madrid Protocol since 7 November 2017, so an applicant with a Thai basic application or registration may file one international application through the Department of Intellectual Property to WIPO and designate member countries. Each designated office still examines the mark under its own national law.

Which court hears IP disputes in Thailand?

The Intellectual Property and International Trade Court, a specialised court with civil and criminal jurisdiction over IP and international trade matters, including trademark, copyright and patent infringement and licensing disputes. Filing rules and jurisdiction are published by the Office of the Judiciary.

What IP housekeeping should a brand do before selling in Thailand?

Clear the name through a DIP search before launch, file in the classes that match the actual goods or services, put assignments and licences in writing, and keep continuous evidence of use — packaging, invoices and advertising. Use evidence matters both in infringement actions and in opposition or cancellation proceedings.

Do I have to register a trademark in Thailand to enforce it?

Registration with the Department of Intellectual Property gives the clearest basis for enforcement. Unregistered signs may still be protected through passing off and other causes of action, but the evidentiary burden is heavier and the outcome less predictable. If your priority is enforcement, secure the registration first and keep proof of first use, marketing spend and sales in Thailand as supporting evidence.

How do I use a Thai IP judgment abroad?

Request a court-certified copy of the judgment from the court that decided the case, then have it translated and legalised by the Department of Consular Affairs. If the destination country requires it, add authentication by that country's embassy in Thailand. The most common rejection reasons are missing certification stamps on some pages and party names spelled differently from the passport. Check case numbers, dates and name spellings across every page before submission.

Practical Q&A

Practical questions · Near me / DIY / Required documents

Is there a service point near me?

Our main offices are Lat Phrao 95 (Bangkok), Khon Kaen and Udon Thani. We serve the whole country through scans and document courier, and can meet at city rail stations or malls. Ask our team by phone, LINE or email for the most convenient option.

Can I handle this myself?

Many steps can be done personally under the relevant authority's rules. What usually costs time is the wrong sequence, a translation format that does not match the requirement, or a source document version the recipient will not accept. Check the destination checklist before starting and ask us if anything is unclear.

Which documents should I prepare?

Generally the original document from the competent authority, the owner's ID or passport, a translation in the format the destination requires, and a power of attorney if someone acts for you. Details vary by service type — ask our team for a case-specific checklist.
Practical advice & cautions

Legal matters and litigation: advice and cautions

Before you start

  • Check the limitation period first

    Different claims carry different prescription periods under the Civil and Commercial Code. Knowing when the clock started dictates whether to negotiate, send a demand letter, or file immediately.

  • Collect evidence in an admissible form

    Chats, emails and transfer slips should preserve timestamps and identifiable parties. Foreign-language documents need a Thai translation to be used in court.

  • Consider mediation alongside litigation

    Thai courts offer mediation before and during proceedings. A compromise agreement recorded by the court is enforceable and usually far faster than a full trial.

  • Execute the power of attorney correctly from the start

    If you are abroad, sign before a Thai embassy or consulate officer, or before a notary followed by legalisation, so the document is accepted by Thai courts and agencies.

Common reasons documents get rejected

  • Missing court deadlines or demand-letter periods

    Filing deadlines and hearing dates are binding; default can lead to an ex parte judgment. Contact counsel as soon as any court document arrives.

  • Expecting a guaranteed outcome

    No lawyer or provider can guarantee a judgment, and advertising guaranteed results conflicts with professional conduct rules. What can be assessed is risk, relevant precedent and settlement options.

  • Submitting uncertified translations

    Translations used in court or before agencies must be certified by the translator, and in some cases legalised by the Department of Consular Affairs. Machine translations are commonly rejected.

  • Discussing the case publicly

    Posting party details or allegations while proceedings are live can create separate defamation exposure and damage the underlying case.

Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
