Koh Samui real estate lawyers play an important role when buying, selling or investing in property on the island. Thai property transactions can involve land title checks, ownership structures, building documentation, contracts, registered property rights, government taxes and procedures at the Koh Samui Land Office.
Using experienced Koh Samui real estate lawyers gives buyers access to independent legal advice before committing substantial funds to a property. A lawyer can investigate the property, check the seller's authority, review contracts and identify potential legal issues before completion.
Estate Samui Properties can provide buyers with general information about purchasing property and the local Koh Samui real estate market. However, an estate agency does not replace independent legal representation. Buyers should appoint a qualified property lawyer in Koh Samui to provide advice according to their individual circumstances.
This guide explains the services normally provided by Koh Samui real estate lawyers, including property due diligence, title deed checks, leasehold and freehold structures, company checks, contracts, Land Office transfers and property taxes.

What Services Do Koh Samui Real Estate Lawyers Provide?
The role of a property lawyer is not simply to prepare a contract. A good lawyer investigates the property, the seller and the proposed ownership arrangement before advising the client on the transaction.
Typical real estate legal services in Koh Samui can include:
- Property due diligence
- Land title verification
- Checking mortgages and registered encumbrances
- Reviewing access and servitude rights
- Building permit and construction document checks
- Reservation Agreement review
- Sale and Purchase Agreement preparation
- Lease agreement preparation and registration
- Condominium foreign freehold checks
- Company and corporate due diligence
- Advice concerning property ownership structures
- Transfer tax and government fee calculations
- Power of Attorney preparation
- Representation at the Koh Samui Land Office
- Property transfer and registration
- Registration of additional property rights where appropriate
- Legal assistance with off-plan developments
- Property dispute resolution
The exact services required will depend on the property being purchased, its ownership structure and the circumstances of the buyer and seller.
When Should You Appoint a Property Lawyer?
Ideally, buyers should appoint their lawyer before paying a substantial deposit or signing an unconditional purchase agreement.
A Reservation Agreement may appear straightforward, but it establishes important obligations between the buyer and seller.
Your lawyer can review issues including:
- Whether the reservation deposit is refundable
- Circumstances allowing either party to terminate
- The due diligence period
- The deadline for signing the Sale and Purchase Agreement
- What happens if legal problems are discovered
- Conditions applying to the deposit
- Documents the seller must provide
- The proposed completion date
- Seller and buyer default provisions
Where possible, the agreement should provide adequate time for legal due diligence before the buyer becomes unconditionally committed to completing the purchase.
How Koh Samui Real Estate Lawyers Handle Property Due Diligence
Property due diligence is one of the most important services provided by Koh Samui real estate lawyers. The purpose is to establish exactly what the buyer is purchasing and identify legal issues before substantial funds are committed.
The lawyer should confirm that the property being sold corresponds with the documentation presented by the seller and identify anything that could adversely affect the buyer's ownership or use of the property.
For a broader explanation of title deeds, ownership options and the complete purchasing process, see our Buying Property on Koh Samui – Property Buyer's Guide.
Land Title Verification
The lawyer will normally inspect the land title and confirm the registered owner.
Different categories of land documents exist in Thailand, so the title type needs to be clearly understood. A Chanote is generally considered the strongest form of Thai land title because its boundaries have been officially surveyed and recorded.
However, having a copy of a Chanote does not mean the legal investigation is complete. The lawyer should check the title and relevant records with the Land Office.
Mortgages and Other Registered Rights
A land title can contain registered legal rights or financial obligations that may affect the property.
These may include:
- Mortgages
- Leases
- Usufructs
- Superficies
- Servitudes
- Other registered rights or restrictions
The lawyer should determine which rights will remain after completion and which must be discharged before or during the transaction.
This is particularly important where the seller has borrowed money against the property or another party has registered rights over the land.
Legal Access to the Property
Access is an important consideration on Koh Samui, particularly for villas situated on hillsides, private roads or within developments.
A road physically leading to a property does not necessarily mean permanent legal access exists.
A property lawyer should therefore establish whether access comes directly from a public road, forms part of the property title or is protected by a registered servitude or another appropriate legal arrangement.
Checking Buildings and Construction Documents
Property due diligence should not stop with the land.
For a house or villa, the lawyer may also investigate the legal documentation relating to the building itself.
Depending on the property, checks can include:
- Building permits
- Approved construction information
- House registration documents
- Building ownership
- Planning considerations
- Zoning restrictions
- Environmental regulations
- Relevant construction restrictions
Properties near beaches, on hillsides or within environmentally controlled areas can require additional investigation because construction regulations on Koh Samui vary according to factors such as location, elevation and land characteristics.
Buyers interested in purchasing land should also view our Koh Samui land for sale page, where additional information about land measurements, title considerations and development is available.
Checking the Property Seller
The lawyer should establish that the seller has the legal authority to complete the transaction.
For an individually owned property, this normally includes checking identification documents and confirming legal ownership.
Where a Thai company owns the property, additional corporate checks may be required.
These can include:
- Company affidavit
- Current shareholders
- Directors
- Authorised signatories
- Company accounts
- Corporate obligations
- Existing liabilities
- Relevant company resolutions
Buying shares in a company that owns property is fundamentally different from simply transferring a land title. In this situation, due diligence needs to examine the company as well as the property itself.
Foreign Ownership and Property in Thailand
Foreign buyers should understand their legal ownership position before committing to a property purchase.
Foreign nationals are generally restricted from directly owning land in Thailand, although limited statutory exceptions exist. Condominium ownership operates under a different legal framework.
A lawyer should explain the legal options available for the individual transaction rather than applying the same ownership structure to every property purchase.
Foreign Freehold Condominium Ownership
Qualifying foreign nationals can directly own condominium units in their own name, subject to the foreign ownership quota within the registered condominium development.
Foreign ownership is generally limited to 49% of the aggregate unit area within a registered condominium development.
A lawyer handling a condominium purchase can investigate:
- The condominium title
- Foreign ownership quota availability
- Condominium juristic person documentation
- Outstanding common-area fees
- Transfer requirements
- Foreign currency documentation
- Existing mortgages or encumbrances
Documentation from the condominium juristic person may also be required before the transfer can take place.
Leasehold Property in Koh Samui
Leasehold property is commonly encountered within the Koh Samui villa market, especially where the underlying land cannot be directly owned by the foreign buyer.
Under Thai law, the normal maximum registered term for a lease of immovable property is 30 years.
A lease exceeding three years should be made in writing and registered with the relevant authority to remain enforceable for a period exceeding three years.
A lawyer can draft or review provisions covering matters including:
- Lease duration
- Registration
- Rent
- Assignment
- Subletting
- Sale or transfer of the leasehold interest
- Responsibilities of the landlord and tenant
- Construction and building ownership
- Termination
- Succession
- Renewal provisions
Buyers should distinguish between the initial registered lease term and contractual promises concerning future renewals.
Any proposed lease renewal structure should be reviewed carefully by an independent lawyer so the buyer understands exactly how the arrangement works and what protections are available.
Usufruct, Superficies and Other Registered Property Rights
Depending on the transaction, a lawyer may also discuss additional legal rights that can be registered over property.
These can include a usufruct, which can provide rights to use or benefit from property, and superficies, which can provide rights relating to ownership of a building situated on land owned by another party.
Other arrangements may also be available depending on the transaction and the circumstances of the parties.
These rights are not interchangeable with ownership or a lease. Their suitability and duration should therefore be considered carefully with an experienced Thai property lawyer.
Company-Owned Property in Koh Samui
Some Koh Samui properties are legally owned by Thai limited companies.
If a buyer is considering acquiring shares in a company rather than transferring the underlying property, the legal investigation becomes more extensive.
The lawyer may need to examine:
- Shareholder history
- Directors
- Company accounts
- Tax filings
- Debts and liabilities
- Existing contracts
- Loans
- Company assets
- Litigation
- Corporate compliance
- Ownership of the property
- Authority to transfer shares
Acquiring an existing company means acquiring its corporate history as well as its assets.
For this reason, a buyer should never assume that purchasing shares in a property-owning company is equivalent to purchasing a clean property title.
Thai law also prohibits nominee shareholding structures intended to unlawfully circumvent restrictions applying to foreigners. Anyone considering a company-based transaction should therefore obtain independent legal and corporate advice before proceeding.
Koh Samui Real Estate Lawyers and Sale and Purchase Agreements
Once due diligence has been satisfactorily completed, experienced Koh Samui real estate lawyers can prepare, negotiate or review the final Sale and Purchase Agreement.
The contract should clearly identify:
- The buyer and seller
- The property being sold
- The agreed purchase price
- Deposits already paid
- The payment schedule
- The completion date
- The proposed ownership structure
- Furniture and fixtures included in the sale
- Transfer expenses
- Taxes
- Conditions that must be satisfied before completion
- Seller warranties
- Buyer and seller default provisions
- Termination rights
- Treatment of deposits following a breach
For off-plan properties, the agreement may also cover construction specifications, staged payments, completion deadlines and remedies for construction delays.
The buyer's lawyer represents the buyer's legal interests when reviewing and negotiating these terms.
Legal Services for Off-Plan Property Purchases
Buying an unfinished villa or condominium involves additional considerations because the buyer is purchasing a property that may not yet exist in its final form.
Legal checks may therefore extend beyond the property title itself.
A lawyer can investigate matters such as:
- The developer company
- Ownership of the development land
- Mortgages registered over the land
- Building permission
- Development contracts
- Construction timetable
- Payment schedule
- Completion guarantees
- Delay provisions
- Transfer arrangements
- Common-area obligations
Payments should correspond with clearly defined contractual obligations and construction milestones where appropriate.
The legal documents should explain not only what happens when construction proceeds correctly but also what happens if the project is delayed, construction stops or the developer fails to perform its contractual obligations.
Property Transfer at the Koh Samui Land Office
For transactions requiring Land Office registration, the lawyer normally prepares the necessary documentation before completion.
Koh Samui real estate lawyers can also coordinate the documents required for registration and, where legally appropriate, represent a client under an authorised Power of Attorney.
Depending on the transaction, the lawyer may:
- Prepare transfer documentation.
- Confirm the final Land Office assessment.
- Calculate applicable government charges and taxes.
- Prepare a Power of Attorney where required.
- Coordinate with the seller and their representatives.
- Attend the Land Office.
- Register the property transfer, lease or other legal rights.
- Check the updated title documentation following registration.
After registration has been completed, the lawyer should provide the client with copies of the relevant registered documents.
Can a Lawyer Complete a Property Transfer if the Buyer Is Overseas?
In many transactions, yes.
Where legally appropriate, a buyer or seller who cannot personally attend the Land Office may authorise another person to act through a correctly prepared Power of Attorney.
The lawyer should advise how documents need to be signed, witnessed, translated, certified or legalised where necessary.
Buyers should not assume that an ordinary Power of Attorney prepared overseas will automatically be accepted for a Thai property transaction.
Property Taxes and Transfer Fees in Thailand
A property lawyer can also calculate the estimated government charges associated with completion.
Depending on the transaction and circumstances of the seller, costs can potentially include:
- Transfer registration fee
- Withholding tax
- Specific Business Tax
- Stamp duty
- Lease registration fees
- Other applicable registration charges
The calculation varies according to factors including ownership, the government assessed value, the sale price, the seller's legal status and the length of time the property has been held.
The Sale and Purchase Agreement should clearly identify which party has agreed to pay each expense.
Government taxes, transfer charges and temporary incentives can change. Buyers and sellers should therefore confirm current costs with their lawyer immediately before completion.
Legal Services for Koh Samui Property Sellers
Property lawyers are not only used by buyers.
A seller may appoint a lawyer to:
- Prepare the Sale and Purchase Agreement
- Review Reservation Agreement terms
- Prepare company documentation
- Calculate transfer costs
- Discharge an existing mortgage
- Prepare Powers of Attorney
- Resolve title issues
- Coordinate the Land Office transfer
- Review tax consequences
- Deal with an existing lease or tenant
Where the property is company-owned, the lawyer can also prepare relevant corporate resolutions, company documents and share-transfer paperwork where required.
The Typical Koh Samui Property Legal Process
Every transaction is different, but a straightforward property purchase will often follow a process similar to the following.
Step 1 – Property Selected
The buyer and seller agree the main commercial terms of the transaction.
Step 2 – Reservation Agreement
A Reservation Agreement records the basic terms of the proposed sale and normally involves payment of a reservation deposit.
Step 3 – Independent Lawyer Appointed
The buyer appoints an independent property lawyer to act on their behalf.
Step 4 – Property Due Diligence
The lawyer investigates the land title, property, seller, legal access, registered rights and other relevant documentation.
Step 5 – Due Diligence Report
The buyer receives the lawyer's findings. Any identified problems can then be discussed or resolved before the buyer proceeds further.
Step 6 – Sale and Purchase Agreement
The final contract is drafted, reviewed and negotiated before being signed by the parties.
Step 7 – Pre-Completion Preparation
The parties prepare payments, identification documents, company documents and any required Powers of Attorney.
Step 8 – Land Office Registration
Ownership, leasehold rights or other property rights are registered where applicable.
Step 9 – Completion
The final payment is made in accordance with the contract and the buyer receives the appropriate legal and property documentation.
For off-plan developments, company share transfers or more complicated ownership arrangements, additional legal stages may be required.
Why Independent Koh Samui Real Estate Lawyers Matter
The seller, developer, buyer and estate agent do not necessarily have identical interests.
For this reason, buyers should have access to an independent lawyer acting specifically for them.
The lawyer should be prepared to identify potential problems rather than simply process documents.
A thorough property lawyer should be able to explain:
- Exactly what you are buying
- Who legally owns the property
- Whether the seller has authority to sell it
- What legal rights are registered against the property
- Whether permanent legal access exists
- Whether relevant building documentation is available
- How your ownership or property rights will be structured
- What contractual protection you have
- What taxes and government fees may apply
- What documentation you will receive following completion
If something cannot be adequately verified, the buyer should know before making substantial non-refundable payments.
Frequently Asked Questions About Koh Samui Real Estate Lawyers
Do I need a lawyer to buy property in Koh Samui?
Using a lawyer is strongly recommended. A lawyer can verify the property's legal position, review contracts, investigate ownership and encumbrances and assist with the Land Office registration process.
What does property due diligence include in Thailand?
Due diligence can include checking the land title, registered owner, mortgages, leases, servitudes, legal access, building documentation, the seller's legal authority and other matters affecting the property.
Can foreigners own property in Koh Samui?
Foreign nationals can own qualifying condominium units directly within the applicable foreign ownership quota. Direct foreign ownership of land is considerably more restricted, so buyers of villas or landed property should obtain independent legal advice regarding the options suitable for their circumstances.
Can foreigners have a 30-year property lease?
Thai law permits leases of immovable property for terms of up to 30 years. A lease exceeding three years should be in writing and registered with the relevant authority to remain enforceable beyond three years.
Can my lawyer represent me at the Koh Samui Land Office?
In many transactions, a lawyer or another authorised representative can act under an appropriate Power of Attorney. Your lawyer should confirm the requirements for your particular transaction.
Should I use the property developer's lawyer?
A developer's lawyer primarily represents the developer. Buyers may therefore prefer to appoint an independent lawyer who can review the transaction specifically from the buyer's perspective.
Should due diligence happen before or after paying a deposit?
Ideally, substantial or non-refundable payments should not be made before appropriate legal checks have taken place.
Where a Reservation Agreement and deposit are required first, the agreement should clearly establish the due diligence period and the circumstances under which the deposit will be returned if the transaction cannot legally proceed.
How much does a property lawyer cost in Koh Samui?
Legal fees depend on the complexity of the transaction and the amount of work required.
A straightforward completed villa purchase may require substantially less legal work than an off-plan development, company acquisition or transaction involving complicated land title or corporate issues.
Buyers should obtain a written quotation explaining exactly which legal services are included.
Buying Property in Koh Samui?
Buying a villa, condominium or land-related property in Thailand requires a clear understanding of exactly what is being purchased and how the buyer's legal rights will be protected.
Estate Samui Properties can help buyers locate suitable properties, explain the local market and coordinate the transaction between buyers, sellers and their appointed lawyers.
However, legal advice should always come directly from a qualified lawyer acting for the client.
Working with independent Koh Samui real estate lawyers alongside an experienced local estate agency can provide buyers with a clearer and more structured route from property selection through to legal completion.
