Frequently Asked Questions

Foreigners must provide a passport, an affidavit of freedom to marry issued by their embassy, and certified Thai translations of required documents.

  • Penalties range from fines (up to 50,000 THB per violation) to criminal liability for directors. Non-compliance can also result in business license suspension.

  • Foreign marriages may be recognized, but registration or legal verification in Thailand is often required for immigration, inheritance, or divorce purposes. The recognition depends on the specific country and circumstances. Professional legal verification is strongly recommended.

What Sets Us Apart

All About Us

➢ Accounting & Auditing 

Proper accounting and auditing are essential for any business operating in Thailand to ensure compliance with local laws, maintain financial transparency, and make informed business decisions. Thai companies are required to follow the Thai Financial Reporting Standards (TFRS), maintain accurate financial records, and submit annual financial statements to the Revenue Department. Failure to comply with these regulations can result in penalties, legal issues, or operational difficulties.

Auditing is a crucial part of maintaining financial integrity in Thailand. It provides an independent review of a company’s financial records, identifies discrepancies, and ensures that accounting practices align with legal and regulatory standards. Both local and foreign-owned companies may be required to have their accounts audited annually, particularly if they are registered as a limited company or if they seek Board of Investment (BOI) benefits. 

Our team of legal and accounting experts assists businesses with all aspects of accounting and auditing in Thailand. We help ensure that your financial records are accurate, compliant, and fully prepared for submission to government authorities. Whether you need assistance with bookkeeping, tax filing, or a full audit, our lawyers and accountants work together to provide comprehensive support, safeguarding your business from legal risks and enabling smooth financial operations.
