Contract drafting and review in Thailand

A sound contract starts with clearly stated rights, duties and conditions before signing. We draft and review Thai and bilingual contracts under the Civil and Commercial Code and topic-specific laws; interpreting disputes is for the courts or the forum the contract names.

How a contract is put together

  1. Step 1

    Define the purpose and parties

    Summarise what the contract covers, who the parties are, and whether a specific law applies — for example leases, employment or controlled consumer contracts.

  2. Step 2

    Set the key terms

    Fix the price, duration, delivery, liability, termination and dispute resolution clearly before drafting legal language.

  3. Step 3

    Draft or review the document

    Prepare a draft or review the counterparty's version, flagging risky or unclear clauses with suggested changes.

  4. Step 4

    Prepare a bilingual version where needed

    Where a party is foreign, a bilingual contract should state which language prevails, reducing the risk of conflicting texts.

  5. Step 5

    Sign and keep the evidence

    Check signing authority, witnesses and attachments, and keep originals for every party. Some contracts must be in writing or registered to be enforceable.

Points to check before signing

  • Some contracts must follow a legal form — in writing, with witnesses, or registered — or they cannot be enforced.
  • Contracts on the Consumer Protection Board's controlled list carry mandatory terms that cannot be contracted out of.
  • A bilingual contract should state which language governs, because diverging translations can themselves become the dispute.
  • Choice of law and dispute forum matter greatly in cross-border contracts; agree them before signing.

Drafting and review fees depend on the contract type, length and number of languages. We quote after reviewing the details; no fixed price is shown on this page.

Frequently asked questions

Is a verbal contract enforceable?

In principle a contract forms by agreement, but the law requires some contracts to be in writing or witnessed to be enforceable in court — such as a sale of immovable property — so always put it in writing.

Is an English-language contract valid in Thailand?

Yes, but a Thai translation may be needed if a dispute reaches a Thai court. A bilingual version from the start reduces that risk.

How should dispute resolution be stated?

State whether disputes go to Thai courts or arbitration, and which law governs — especially for contracts with foreign parties.

Can a signed contract be amended?

Yes, with all parties' consent, usually through a written addendum. One-sided changes without a contractual right may be a breach.

What is a controlled consumer contract?

A contract type the Consumer Protection Board has declared controlled, such as residential leases by business operators, with mandatory terms the operator must follow.

What does it cost and how long does it take?

It depends on the contract's type and complexity; we do not promise a fixed period. We quote after reviewing the details. No guarantee of outcome and no refund policy.
