Property and land transaction document certification

This page sets out what property and land transaction document certification requires: 6 documents to prepare, 5 steps in the order they must actually happen, preparation advice, and the mistakes that most often send a file back. If you would rather not run the process yourself, our team can handle it end to end.

Documents to prepare

  • Original document plus one clear copy of every page
  • Copy of the passport or Thai national ID card of the signatory
  • Written statement of the purpose and the receiving authority
  • Supporting records the receiving authority lists in its own checklist
  • Power of attorney if the signatory cannot attend in person
  • Contact details for follow-up questions from the receiving authority

Process steps

  1. Step 1. State the purpose and the receiving authority so the correct level of certification is chosen.
  2. Step 2. Send scans of every page so completeness can be checked before work starts.
  3. Step 3. Prepare the translation or the instrument in the format the receiving authority requires.
  4. Step 4. Sign or certify before the officer authorised by law to witness that document type.
  5. Step 5. Collect the finished set and keep a copy for the next filing.

What gets files rejected

  • Land office documents must match the title deed number exactly.
  • Powers of attorney for land transactions use a prescribed form.
  • Spell every name exactly as it appears in the passport, across every document in the same bundle.
  • Never remove staples or separate pages that an authority has bound and stamped across the seam.

What this certified set is used for

  • Property purchase and transfer
  • Mortgage registration
  • Lease and usufruct filings

Talk to us before you commit to anything

Many clients arrive with one set of documents while the destination expects a different one. We start by asking where you are filing, for what purpose, and by when — then tell you plainly what is required, including the steps you can complete yourself at no extra cost. A team with over 15 years in cross-border documentation is available before you spend time on the wrong route.

  • Destination requirements explained in plain language.
  • A clear statement of which steps your case needs and which it does not.
  • Help sequencing multiple documents across multiple authorities.
