How Can I Verify Buildability & Encumbrances before Purchase?

Buildability and encumbrances are shown in official records, not marketing blurbs. Start with the land title documents at the Land Department and local office to confirm the owner name, the title type, and any liens, easements or encumbrances registered against the property. Ask for a recent official title deed copy and a land office extract showing the exact boundaries and the land-use designation. Verify legal access rights, such as whether there is a deeded road or a right of way and if access is shared with neighbors. Next, check whether the land is zoned and allowed for the intended development: confirm current zoning, building height limits, setbacks, slope/landslide considerations, and any special permits required. Confirm infrastructure status: water, electricity supply, drainage, and road access. Request concept designs or preliminary engineering input to test feasibility and costs. Engage independent professionals—a Thai lawyer or land professional, and a licensed architect or engineer—to review the documents, identify hidden risks, and quantify any encumbrances. Do not rely on the seller’s deeds alone, and avoid relying on unaudited site plans or speculative approvals. Finally, ensure the vendor and/or seller provides clear disclosures about all restrictions before you sign a sale agreement.
