Employment Contract in Thailand: Template and E-Signing Guide

A solid employment contract needs to clearly state the position, salary, probation period, and termination conditions. Once it's drafted, sending it for electronic signature via OTP and an audit trail carries the same legal weight as a signature on paper, under the Electronic Transactions Act B.E. 2544 (2001) (ETA).

Finding an employment contract template is easy. Getting it signed without printing, signing, scanning, and emailing it back is harder. This guide covers both the structure your contract needs and the full end-to-end process for sending it out for signature online, in one article.

TL;DR: A solid employment contract needs to clearly state the position, salary, probation period, and termination conditions. Signing it electronically (via OTP + audit trail) carries the same legal weight as a paper signature under the Electronic Transactions Act B.E. 2544 (2001) (ETA). This article covers the contract's required structure and the full end-to-end process for sending it out for signature online: no printing, scanning, or emailing back and forth.

Key Takeaways

• An employment contract must clearly state the position, salary, term, and termination conditions.
• Signing online via OTP and an audit trail carries the same legal weight as a paper signature, under ETA 2544.
• A customizable employment contract template saves time compared with drafting from scratch every time.
• A staff NDA should be a separate document from the employment contract, not merged into the same file.
• OTP and an audit trail strengthen evidentiary weight; they don't guarantee the outcome of a case.

Before You Start: What to Prepare

Before drafting an employment contract, have this information ready: the job title and responsibilities, the salary rate and pay cycle, the start date, the benefits the company offers, and a ready-to-use account on an online document-signing platform. Altogether, this typically takes about 15 minutes to prepare for a standard position.

Step 1: The Structure Your Employment Contract Needs

A complete employment contract needs several core structural elements before you even get to the details specific to each company. These elements are what make the contract clear enough to prevent future disputes.

• The parties' details: the full names of the employer and employee, addresses, and relevant ID numbers
• Job title and responsibilities: state clearly what the employee's duties are, to prevent misunderstandings later
• Salary and pay cycle: the amount, the payment date, and the payment method
• Probation period: if there is one, state the duration clearly
• Termination and notice conditions: the notice period and related conditions

Step 2: Use a Ready-Made Template Instead of Writing from Scratch

Drafting an employment contract from scratch every time is an unnecessary burden for most businesses, compared with starting from a customizable template. A template designed for the Thai legal context reduces the risk of forgetting a key element, and saves significant time compared with writing it out yourself every time.

Jabmue has a ready-to-use bilingual Thai-English employment contract template in its document gallery, covering the core structure described above. That's different from a generic template-download website that just hands you a Word or PDF file and stops there, because it also carries straight through into the online signing process, in the same system.

Something often overlooked: a staff NDA should be a separate document from the employment contract, not merged into the same file, because a confidentiality agreement has different conditions and a different validity period from the main employment contract. The document gallery has a separate staff NDA template you can use alongside it.

Step 3: Customize the Company's Specific Terms

Once you've picked a template, the next step is customizing the fields to match the specific conditions for the company and the role, including the job title, salary rate, benefits, and probation period if there is one.

A word of caution: don't take probation-period or notice-period figures from a general source without verifying them first. These figures depend on labor law and may vary by type of employment. Consult a legal advisor or your in-house legal team before setting the figures your company will use as a standard.

Step 4: Send It to the Employee for Online Signature

Once the contract is ready, the next step is sending the signing link to the new employee via email or LINE, without requiring them to create any account. The employee opens the link, verifies their identity via OTP by email or phone number, and can sign the document immediately on their phone or computer screen.

The system records an audit trail throughout the process, including when the document was opened, when OTP was verified, when it was actually signed, and the device used. OTP and an audit trail strengthen evidentiary weight, but that's not a guarantee of the outcome of a case if a dispute arises in the future.

Step 5: Verify Identity and Track Status

HR can track the contract's status in real time throughout the process, whether the document has been opened yet, is still waiting to be signed, or has already been fully signed. Automatic notifications cut down on the need to chase things up manually by phone or chat.

Having clear visibility into status also solves the delays that are common in a paper-based process, such as an employee forgetting to send the document back, or the document getting lost along the way.

Step 6: Store It and Retrieve It Later

Once it's fully signed, the signed contract, complete with its audit trail, is stored in the system for retrieval at any time, with no need to dig through paper files or worry about a document going missing.

HR can download the signed contract along with its full signing history whenever needed, for example for an internal audit or a dispute that requires supporting documentation.

Common Mistakes

The most common mistake in the employment contract process is the lack of clear evidence of consent, whether that's a verbal agreement with no supporting document, or sending a PDF for signature through chat with no identity verification at all.

Other common mistakes include not having a witness when one is required under a specific condition, and forgetting to draw up a staff NDA separately from the main employment contract, even though the two documents serve different purposes and carry different conditions.

Frequently Asked Questions

Is a verbal employment contract valid?

Under Thai labor law, a verbal employment contract can be binding in some cases, but proving the agreed conditions becomes far harder without a supporting document. Businesses should always have a written contract to prevent disputes and misunderstandings.

Is signing an employment contract online legally valid?

Yes. Signing an employment contract electronically via OTP and an audit trail is legally binding, carrying the same legal weight as a signature on paper, under the Electronic Transactions Act B.E. 2544 (2001). Read the full legal article for more detail.

Do I need an NDA separate from the employment contract?

Yes, you should. A staff NDA should be a separate document from the main employment contract, because a confidentiality agreement has different conditions and a different term from the employment contract. Keeping the documents separate also lets you edit each one independently without affecting the other.

How many years should an employment contract be kept?

How long an employment contract needs to be retained depends on labor law requirements and each company's internal policy. Check with your legal advisor or in-house legal team to set a retention policy that fits your business.

Can a document signed with an electronic signature be used as evidence in court?

Yes. An employment contract signed electronically can be used as evidence in court. The weight of the evidence depends on how rigorous the identity-verification process was. Read more at the evidentiary weight of a contract signed online

Conclusion

A complete employment contract needs the full core structure, and signing it electronically via OTP and an audit trail is legally binding, carrying the same weight as a paper signature. Rather than keeping the drafting and signing steps separate, using a ready-made template together with an online signing system in one place lets the whole process wrap up in just a few minutes, with no printing, scanning, or emailing back and forth.
