The legal framework applicable to buying a house in Koh Samui
Are you looking to buy a house in Koh Samui? Under Thai law, specifically the Land Code Act B.E. 2497,
Foreign nationals cannot own land throughout the Kingdom of Thailand, including on the island of Koh Samui. This prohibition covers both direct and indirect ownership.
Despite this restriction, Thailand’s legal system provides several legitimate pathways that allow foreign nationals to invest in Koh Samui’s real estate while complying with national laws. These options include signing a long-term lease under the Thai Civil and Commercial Code, purchasing a condominium unit freehold under the Condominium Act B.E. 2522, or building a residential home on leased land with appropriate legal documentation.
This article provides a full legal overview of the process for foreigners buying a house in Koh Samui. It explains every legal pathway, outlines requirements, and offers a step-by-step guide to help safeguard your investment.

Step 1: Choose the right type of property to buy a house in Koh Samui
The 30-year leasehold agreement
While Thai law prohibits foreigners from owning land, investors have many options when buying a house in Koh Samui. One popular method involves leasing land for up to 30 years, as the Thai Civil and Commercial Code allows. The lessee must execute the lease in writing and register it at the local Land Office to enforce it against third parties. Under the lease, the foreign lessee retains the exclusive right to occupy and use the land as a residence during the term.
Investors can arrange payment plans for the lease on a lump-sum or installment basis. The contract may also grant rights to transfer or sublease, provided it explicitly includes these provisions.
Acquiring a condominium unit in full ownership
Buying a condominium unit provides a popular and safe way to purchase a house in Koh Samui. The Condominium Act B.E. 2522 allows foreign nationals to own a freehold condominium unit, as long as investors respect the 49% foreign ownership limit across the building’s entire floor space.
The Land Department requires buyers to register ownership, and the foreign buyer receives a title deed in their own name. This process offers one of the easiest legal routes for foreigners who want to invest in real estate with clear legal protection and transferability.
Constructing a house on leased land
Foreigners can also consider buying a house in Koh Samui by building on leased land. Although they cannot own the land, they may own the building they construct, provided the lease agreement explicitly grants this right.
Before starting construction, the lessee must obtain a building permit in their own name. Construction and lease agreements must include clear covenant clauses covering ownership, rights of use, and disposal of the building once the lease ends. Depending on the lease, the lessee can move, sell, or renegotiate the building. This strategy suits expats who want to buy standalone houses in Koh Samui while following the law.
Step 2: Execute a due diligence before buying a house in Koh Samui
A legal due diligence is a must before buying a house in Koh Samui.
With the assistance of a law firm, investors verify the title deed, check for any encumbrances, and ensure compliance with zoning and building restrictions on the property.
The most secure land title in Thailand is the Chanote (Nor Sor 4 Jor), which confirms precise land boundaries and full ownership rights. Less secure titles like Nor Sor 3 or Nor Sor 3 Gor may involve disputes or limitations. A lawyer should confirm that the seller holds lawful ownership or leasing rights.
If the buyer holds the property under a Thai company, they must review corporate documents such as the Company Affidavit, shareholder list, and resolutions approving the transaction.
Investors must also check for existing mortgages, servitudes, or litigation. If the property involves a building, the buyer should verify permits and land-use regulations. If purchasing under a lease, the buyer must register the lease and ensure it includes construction and transfer clauses.
Step 3: Sign the reservation agreement to reserve the house you want to buy in Koh Samui
Once buyers complete due diligence, the next step to buy a house in Koh Samui involves signing a Reservation Agreement. This document reserves the property and records the buyer’s intention to proceed with the purchase. It generally includes a deposit and outlines the agreed purchase price, deadlines for contract signing, and terms in case of withdrawal or non-performance.
This agreement does not transfer ownership but serves as a preliminary commitment, protecting the buyer while they finalize the Sale and Purchase Agreement (SPA).
Step 4: Executing the Sale and Purchase Agreement to formalize buying a house in Koh Samui (SPA)
The SPA formalizes the sale and the process of buying a house in Koh Samui. Lawyers draft this document in Thai and often translate it into English for foreign buyers. It includes details such as party identities, property description, payment terms, timelines, and tax allocation.
For leasehold or house-construction contracts, the SPA also identifies the lessee’s construction rights and any related responsibilities of both parties. Once the buyer and seller sign the SPA, it becomes a legally binding contract detailing their agreement for the purchase of a specific property.

Step 5: Transferring funds from abroad to pay for the house you want to buy in Koh Samui
When buying a house in Koh Samui, buyers must transfer funds from abroad in compliance with Thai financial regulations. They must remit these funds through a local bank and provide an FET Form if the amount exceeds USD 50,000.
The buyer must ensure that the name on the fund transfer matches their name in the SPA and land documents. Buyers must also submit the FET Form when repatriating funds during the ownership registration process at the Land Department.
Step 6: Transfer of ownership to register the house you want to buy in Koh Samui
The final step to buy a house in Koh Samui involves officially registering ownership or a lease at the Land Department. Both the buyer and seller (or their legal representatives) must attend on the scheduled date to finalize the transaction.
The Land Officer reviews the documents, registers the transaction, and records the transfer in the registry. The buyer and seller must pay government fees, including transfer tax, stamp duty, Specific Business Tax, or Withholding Tax. The SPA should allocate these costs in advance. Once the parties complete registration and payments, they legally conclude the transaction.
Yellow Book and Pink Card as additional steps : obtain proof of residence
After purchasing a property in Koh Samui (or elsewhere in Thailand), foreign investors can take additional steps to secure proof of residence.
Foreigners can apply for a Yellow Book (Tabien Baan), which establishes residency and simplifies dealings with Thai authorities.
Additionally, the Pink Card, a Thai ID card for foreigners attached to a Yellow Book, serves as an important document for general administrative purposes, such as opening a bank account, accessing medical services, and completing governmental procedures.
