How to Send a Document for Online Signature in 10 Minutes (With Real Screenshots)

Sending a document for online signature takes 5 main steps: pick a template or upload a PDF, place the signature fields, add the signer's name and email, send the link, and have the signer verify their identity with an OTP before signing from their phone or computer. The signer never has to create an account, and the whole process takes under 10 minutes.

This article shows real product screenshots of every step — no mockups — so you can see exactly how short the path is from having a document in hand to holding a fully signed file with supporting evidence.

If you are not yet sure whether a document signed this way is legally binding, start with the basics: are electronic signatures legal in Thailand?

In short: sending a document for online signature takes 5 steps — pick a template or upload a PDF, place the signature fields, add signers, send the link, and have each signer verify their identity with an OTP before signing. No account required, and the whole thing is done in under 10 minutes.

Step 1: Pick a Template or Start From a Blank PDF

There are two starting points: choose from the library of ready-to-use Thai legal contract templates, or upload an existing PDF and place your own fields on it. For contracts you use often — a lease agreement, a consent form, a quotation — starting from a template is much faster, because you never have to lay out the signature fields again.

If your document is not in the template library, or your business already has its own format, you can upload your existing PDF and go straight to placing text fields and signature fields in the next step — no need to retype the whole document.

Step 2: Place Signature, Date, and Text Fields

Once you have chosen a document, the next step is to drag signature fields, date fields, and text fields directly onto the spots where you want them. It works like placing stickers on the page — no need to edit the PDF in a separate program.

If several people need to sign — say a landlord, a tenant, and a witness — you can place separate signature fields for each of them in the right spots in this same step. The system remembers which field belongs to whom in the steps that follow.

Step 3: Add Signers — Names, Emails, and Signing Order

Add the people who need to sign by entering just a name and an email address or phone number — signers never have to create an account in advance. If you need signatures in a specific order, for example the client signs first and the business owner countersigns afterwards, you can set the signing order in this step too.

What makes this step so much faster than the traditional way of sending documents: no signer has to install an app or register for anything before signing. All they need is a working email address or phone number.

Step 4: Send the Link — and What the Signer Sees (OTP)

When you hit send, each signer receives a signing link by email or through the channel you chose. Opening the link, they must verify their identity with an OTP code before they can view and sign the document. This is the step that gives the signature its own identity verification, separate from the document itself — it is more than just clicking "accept."

The OTP verification meaningfully strengthens the evidentiary weight of the signature, but it is not a guarantee of how a court will rule — every case has its own context that a court must weigh. What OTP does is improve the chances that your evidence will be accepted, not guarantee the outcome.

Step 5: Track Status and Keep the Evidence (Audit Trail)

After sending, you can track status in real time — who has opened the document, who has signed, and who has not yet. Once everyone has signed, you get the completed PDF with the audit trail attached in the same file. No need to store the signing evidence somewhere separate.

The audit trail records when the document was opened, when the OTP was verified, when the signature was actually made, and details of the device used to sign. This record does not guarantee a court outcome, but it builds a complete picture of the entire signing process — which is highly useful if you ever need supporting evidence later.

Why Not Just Snap a Photo and Send It on LINE?

Photographing a hand-signed document and sending it in a LINE chat is possible, and common in Thailand — but it may not be clear enough when a dispute arises, because there is no identity verification and no systematically verifiable timestamp. A signing link with OTP and an audit trail delivers clearly stronger evidentiary weight.

The good news: you do not have to stop using LINE with your clients at all. Just change what you send — a signing link instead of a photo. For a full comparison of the two approaches, read can you sign documents over LINE?

Frequently Asked Questions

How do I send a document for online signature?

Pick a template or upload a PDF, place the signature and data fields, add the signer's name and email, then send the link. The signer verifies their identity with an OTP and can sign right away from a phone or computer.

Does my client need an account to sign?

No. Signers open the link, verify with an OTP, and sign in the browser — no app to install and nothing to register for before signing.

What is an OTP, and why is it used for document signing?

An OTP is a verification code sent specifically to the signer's email address or phone number. It confirms that the person signing really is the owner of that account, which strengthens the evidentiary weight of the signature.

How long does online document signing take?

The whole process, from preparing the document to sending the link, takes under 10 minutes. How long the actual signing takes depends on the number of signers and how quickly each of them responds.
