How to Sign a Certified Copy of Your House Registration Book

Have you ever wondered exactly how to sign a certified copy of your house registration book? Some people draw one line at the bottom, others draw two. Some sign across the photo. The correct method isn't always obvious, and getting it wrong can leave you vulnerable to fraud or identity theft.


Why Signing a Certified Copy of Your House Registration Book Matters

Signing a certified copy is more than a formality. When you write "certified true copy" and sign your name on a document, you're confirming that the copy is an accurate match to the original. Without this, the document has no legal standing for official transactions, and a poorly signed copy can be misused by bad actors.

Nestopa has put together everything you need to know about certifying copies of your house registration book — so you can do it safely, every time.

How to Sign a Certified Copy of Your House Registration Book

Follow these steps to certify your house registration book safely and correctly.

1. Draw Two Lines Across the Copy and State the Purpose

Draw two straight parallel lines across the copy, spanning both the cover page and the page showing your name. Between those two lines, write a clear statement of purpose. For example: "For job application use only." This prevents anyone from using the copy for something other than what you intended.

2. Add Symbols to Block Any Additions

Once you've written the purpose, add a * or # symbol before and after the text. This makes it much harder for anyone to insert additional words or alter what you've written.

3. Write Today's Date Clearly

Write the full date (day, month, and year) on the copy. This is important. Scammers sometimes retrieve old, discarded documents and try to reuse them. A clear date makes that far more difficult.

4. Sign and Write "Certified True Copy"

Finally, write the words "Certified True Copy" (สำเนาถูกต้อง) and sign your name, ideally overlapping part of the document itself. Signing across the content adds an extra layer of security.


Which Documents Need a Certified Copy Signature?

  • National ID card (front only, or both sides)
  • Driver's licence
  • Government-issued employee ID card
  • Birth certificate
  • House registration book (homeowner copy)
  • House registration book (resident copy)
  • Vehicle registration document
  • Land title deed (Chanote)
  • Financial documents — e.g., bank book front page
  • Income verification letter
  • Salary certificate
  • Employment certificate
  • Educational certificate
  • Academic transcript
  • Job application documents

Now You Know — Sign Your House Registration Book the Right Way

Your house registration book is one of the most important documents you own, and certifying copies of it correctly protects you from misuse. Follow the four steps above every time, draw the double lines, state the purpose, add the symbols, write the date, and sign across the content.

It only takes a minute, but it can save you from a lot of headaches down the line.

Frequently asked questions

Official documents generally prefer blue and black ink. Black ink pens convey a formality and are suitable for official documents, while blue ink is popular because it helps distinguish the original from copies and also stands out more than black ink in some cases.

For complete information, please take photos of the first page (house information) and the page with your name (only one page), then sign to certify the copies as true copies.

For accuracy and security, when signing a copy of your house registration online, use an application like Thai.ID or a photo editing app to scan the document, cross out existing information, add an electronic signature, and clearly state the purpose of use. Never sign without specifying the intended purpose.
