Business decisions where legal input changes the outcome

In a cross-border deal, the commercial team agrees on price and delivery. The legal terms decide whether the rights you negotiated can actually be used. Our role is to show decision-makers the effect of each term before the business is committed.

DecisionWhat the adviser examinesWhat the business gains
Appointing an exclusive distributor in ThailandTerritory, sales rights, minimum purchase targets, restrictions on competition, terminationA clear view of what you are granting and what you can renegotiate before signing
Entering a joint ventureManagement control, reserved matters, deadlock, exitControl and exit rights that match the capital you commit
Supply and manufacturing agreementsSpecifications, inspection, tooling, intellectual property, delivery, liabilityCommercial promises backed by enforceable terms and evidence
Choosing an investment route into ThailandActual business activities, shareholding, licenses, incentives, continuing obligationsA comparison of lawful routes before incorporating or starting operations
Choosing governing law and dispute resolutionSuitability, cost, procedure, and where the counterparty's assets are locatedA realistic assessment of how your contractual rights can be enforced

How we work and how fees are set

  1. Initial inquiry. You tell us the type of transaction, the countries involved and any deadline.
  2. Conflict check. We confirm we can act before asking for confidential documents.
  3. Written scope. We set out the documents, countries, governing law, deliverables, delivery date, rounds of revision and fee.
  4. Work and internal review within the agreed scope.
  5. Delivery and explanation so decision-makers know which terms to accept, negotiate or change.

A 45-minute consultation on a single matter is THB 4,900, payable before the meeting. For document review, contract drafting or project assessment, the fee follows the agreed scope; we confirm deliverables, timing and fees in writing before any work begins.
