Thailand Land Title Types Explained: Know Your Deed Before You Buy or Bid (Transfer, Mortgage, Risk Checklist)

Before buying land, a house, or an auction property, the single most important “before you pay” factor is the type of land title document. Different document types carry different legal strength, different boundary certainty, and different transaction outcomes (transfer, mortgage, development). Thai government materials classify land-right documents into multiple groups and forms—so buyers should understand the big picture first.

1) Why the “title type” matters to buyers

• Defines the level of rights: full ownership vs. rights that require additional steps

• Defines risk: boundary/area clarity, encumbrances, and evidence strength

• Defines what you can do: transfer, mortgage, subdivide, build, or develop
  In short: “different document type = different rules of the game.”

2) The “Title Deed” group (NS.4 family): what it means

In government classification, the Title Deed category sits within the NS.4 family and includes multiple sub-forms (NS.4 and related variants).
Principles buyers should know

• In practice, title deeds are typically the most widely accepted for sale, mortgage, and development

• Always read the registration entries and verify the latest official status at the Land Office—never rely on the front page alone

3) The “Certificate of Utilization” group (NS.3 / NS.3K / NS.3Kh)

Government materials classify NS.3 and its sub-types as “certificate of utilization” documents.
Principles buyers should know

• This is not the same level as a title deed in terms of evidence completeness

• The key risk area is often boundary/area certainty, so verification must be stricter

• Suitable for buyers/investors who understand process, verification, and risk management

4) Common “pre-title / possession evidence” documents (e.g., SK.1, reservation certificates, etc.)

Government classification includes additional document types that operate as possession evidence or pre-title stage documents (for example, SK.1 and other forms listed across official groups).
Principles buyers should know

• These documents can have tighter rules and parcel-specific conditions

• Never decide based on a photo or verbal explanation—verify official status and limitations

5) How to judge “transferable / mortgageable” (professional reading principles)

Use these 3 anchors:

1. Document type: NS.4 family vs NS.3 vs pre-title evidence

2. Registration entries & encumbrances: mortgage, attachment, third-party rights, servitudes, etc.

3. Latest Land Office status: because some restrictions may not appear clearly on the holder’s copy
   This method answers “Can I transfer/mortgage/use it?” with the highest reliability.

6) Universal pre-purchase checklist (also works for auction properties)

• Confirm the document type and obtain verifiable copies

• Verify official land registration records at the Land Office

• Check encumbrances, transfer bans, attachments, and third-party rights

• Check boundaries, area, possession, zoning and government project constraints

• If it is not a title deed, increase boundary/status verification intensity

7) Investor & auction angle: match document type to your strategy

• Rental/hold: prioritize clarity, smooth transfer, lower operational risk

• Renovate/develop: confirm land-use constraints and transaction readiness

• Auction: read sale conditions + verify title type and encumbrances before placing deposits
  Because the wrong title type can break your plan at transfer day.

FAQ

Q1: How is a Title Deed (NS.4 family) different from NS.3 from a buyer’s perspective
A: The principle is the strength/completeness of evidence and clarity of rights. Title deeds are typically more widely accepted; NS.3 requires stricter boundary and status verification.

Q2: Which document types are more likely to carry boundary/area risk
A: As a principle, non-title-deed documents require stricter boundary and official status verification, often relying more on Land Office confirmation.

Q3: Is it enough to check only the document shown by the seller
A: No. You should verify the latest official Land Office status and review full registration entries and encumbrances.

Q4: For auction purchases, how important is the title type
A: Extremely important—it affects transfer, mortgage, practical usage, and post-auction risk.

Q5: Can you buy if the document is not a title deed
A: Sometimes yes, but verification must be stricter and parcel-specific limitations must be understood based on official status.

Q6: What is the special caution for pre-title documents (e.g., SK.1 / reservation forms, etc.)
A: You must confirm what transactions are legally possible and verify status/limitations through official sources.

Q7: Where should you start to confirm real transfer/mortgage feasibility
A: Start with 3 anchors: document type + registration entries/encumbrances + latest Land Office status.

Q8: If the registration entries show encumbrances, should you still buy
A: Sometimes yes, but only after understanding the encumbrance details and evaluating total cost and risk.

Q9: Why do professionals insist on Land Office record verification
A: Because it confirms the latest status and reduces risk from incomplete or outdated information on the holder’s copy.

Q10: If you can do only one thing before paying a deposit, what is it
A: Confirm the document type correctly and verify the latest registration status/entries before any payment.
