International Arbitration Counsel (SIAC · ICC · HKIAC · LCIA)

ทนายอนุญาโตตุลาการระหว่างประเทศ (SIAC · ICC · HKIAC) · § CrossBorder
What to know before you act
Cross-border contracts with Thai companies often choose SIAC, ICC or HKIAC. Thai counsel matter for Thai-law interpretation, gathering evidence and witnesses in Thailand, and planning enforcement against Thai assets from day one. We co-counsel with foreign firms or lead mid-sized cases, from case assessment and arbitrator selection to hearings.
Timing and external dependencies: International cases often take one to two years; expedited procedures are shorter under institutional rules.
Official fee: Fees follow each institution's schedule — use the institution's online calculator.
Timing is not a promise of an outcome or hearing date. Check the notice, limitation period and current authority rules for your matter.
What to send for the first review
Send every relevant page, a dated sequence of events, any hearing or filing deadline, and the outcome you need. This lets counsel identify urgent steps, missing evidence and a precise scope of work.

Frequently asked questions
- Can a foreigner own 100% of a Thai company?
- Generally no for activities listed in the Foreign Business Act, where majority foreign ownership requires a Foreign Business Licence, a BOI promotion, or treaty rights such as the US–Thailand Treaty of Amity. Manufacturing and certain export activities are largely open, and BOI-promoted activities can permit full foreign ownership together with land-holding and visa privileges, so the right structure depends on the specific activity.
- What is the minimum registered capital for a Thai company?
- There is no general statutory minimum for a Thai-majority company, but practical thresholds apply: a fee quoted after review million of paid-up registered capital per foreign work permit, or a fee quoted after review million if the foreigner is married to a Thai national, and a fee quoted after review million per foreign shareholder for a Foreign Business Licence. Capital should therefore be planned around the visa and work-permit outcome you need, not the incorporation minimum.
- How long does company registration take?
- Registration at the Department of Business Development can be completed within one to three working days once the name reservation, shareholder documents and company objectives are ready, and the VAT registration and social security registration follow afterwards. The realistic end-to-end timeline including bank account opening is two to six weeks, with the bank account usually being the slowest step for foreign directors.
- What ongoing accounting obligations does a Thai company have?
- Every Thai company must keep statutory accounts, file monthly withholding tax (PND 1, 3, 53) and VAT (PP 30) returns by the middle of the following month, file the half-year corporate income tax return (PND 51) and the annual return (PND 50), and have its financial statements audited by a Thai CPA and filed with the DBD each year. Dormant companies are not exempt — nil returns and an audited statement are still required.
