What Makes a Company Affidavit Legally Valid?

A company affidavit in Thailand is only valid when it meets legal standards under the Civil and Commercial Code Section 1144 and the Business Registration Act B.E. 2499.

To comply, your affidavit must include:

  • Company name and registration number (in Thai, and English if used)
  • Registered address
  • Corporate objectives as filed with the DBD
  • Directors and authorized signatories, including their scope of authority
  • Shareholding structure and registered/paid-in capital
  • Corporate seal (if applicable)
  • Certification by the Department of Business Development (DBD)

The DBD, part of the Ministry of Commerce, is the official certifying authority. Every affidavit receives a stamp, watermark, and, if digital, a secure QR code for easy verification.

Authoritative details are provided through the Thai Ministry of Commerce – DBD.

Why Is a Company Affidavit Important for Businesses?

A valid company affidavit is required for:

  • Opening business bank accounts
  • Applying for licenses, permits, or government registrations
  • Entering contracts and lease agreements
  • Investor and partner due diligence
  • Verifying representative authority with third parties

The affidavit is publicly accessible, allowing stakeholders to verify a company’s legal status instantly and promoting transparency.

A current, certified affidavit ensures seamless business operations and fosters trust with investors, banks, and regulators.

Required Documents for Registration

To obtain a company affidavit in Thailand, applicants must prepare a specific set of documents for DBD review.

Key required documents include:

  • Company registration certificate (latest version, issued by the DBD)
  • Director identification (passport or Thai ID card)

Company Affidavit Registration & Updates

Steps to Register and Obtain the Affidavit

Obtaining a company affidavit in Thailand starts by choosing between two channels: in-person at the Department of Business Development (DBD) office or online through the DBD e-Service Portal.

Key steps include:

  • Preparing all supporting documents (registration certificate, director’s ID, shareholder list)
  • Submitting your application via your chosen method
  • DBD review and verification of information (expect requests for clarification if discrepancies arise)
  • Receiving the certified affidavit (as a physical document with stamp, watermark, and microtext or as a digitally signed PDF with a QR code, typically within 1-3 business days)

How to Update or Amend Affidavit Details

To amend the affidavit:

  • Gather proof of the change (resolution minutes, identification, revised shareholder list)

Late or inaccurate submissions may result in administrative fines. Proactive amendments prevent compliance setbacks and keep your business agile.

Efficient company affidavit management sets your business up for smoother banking, licensing, and international transactions.

Digital vs Paper Affidavit Verification

How Thailand’s Digital Affidavit System Works

Thailand now issues company affidavits both as paper documents and as secure digital certificates. Both formats are fully recognized by law and can be used interchangeably for official transactions.

Digital company affidavits are secured by:

  • DBD digital signatures
  • In-document watermarks and microtext
  • Unique QR codes for instant verification

This digital shift brings immediate, practical advantages:

  • Faster issuance (often under one business day online)
  • 24/7 access for cross-border and remote business activities
  • Automated audit trails and tamper-evident security

A quick scan of the QR code lets banks or regulatory partners confirm your company’s details in real time.

Ensuring Authenticity & Preventing Fraud

Verifying a company affidavit’s authenticity in Thailand is straightforward when you know what to check.

Inspect for these features:

  • Official DBD stamp (on paper copies)
  • Watermarks and fine-line security patterns
  • Microtext visible under magnification
  • QR code linking to the DBD’s official company database

If any element is missing or your scan reveals outdated data, pause and confirm with the DBD.

Today’s digital affidavits protect stakeholders by providing real-time, transparent verification empowering every business owner and investor to operate with greater confidence.

Common Mistakes & Smooth Registration Tips

Frequent Errors in Affidavit Applications

Many applications for a company affidavit in Thailand are delayed or rejected due to avoidable mistakes.

Top reasons identified by the Department of Business Development (DBD) include:

  • Missing or incomplete information, such as director details or corporate objectives
  • Spelling discrepancies or mismatches between English and Thai documentation
  • Submission of outdated certificates or expired supporting documents
  • Inconsistencies between documents, for example, a shareholder list not matching DBD records

DBD case reviews in 2023 revealed that 1 in 7 applications encountered review queries, causing delays of three to seven business days. Recent regulatory audits found incorrect authorized signatory names led to returned applications.

Streamline your company affidavit registration by following these proven strategies:

  • Conduct a thorough internal review of all documents before submission
  • Use a certified Thai-English translator for any necessary translations
  • Consult legal professionals specializing in company affidavit Thailand requirements
  • Track DBD updates and maintain an ongoing compliance checklist
  • Respond promptly to all DBD information requests or queries

Regular compliance audits and prompt document updates are essential to reducing risk.

For additional guidance, reference the Department of Business Development’s official checklist or connect with a registered corporate legal network.
