Property Acquisition Process in Koh Samui (2025): Step-by-Step Guide

Introduction

The property acquisition process in Koh Samui is a topic of growing interest among European investors, including those from Poland. The island has become one of Thailand's most dynamically developing real estate markets – offering stable returns, transparent regulations, and attractive pricing compared to Phuket.

In this article, we present the complete property acquisition process in Koh Samui, step by step – from selecting a project, through legal analysis, to registration at the Land Office and key handover.

Step 1. Property and Location Selection

In Koh Samui, investors can choose from several main types of properties:

Condominiums – ideal for foreigners (freehold ownership up to 49% of building units).
Pool villas – typically under leasehold model (30-year lease).
Land plots – available as leasehold or through Thai Company structure.

Most popular investment locations:

Bophut / Fisherman's Village – central location, close to beach and marinas.
Chaweng Noi / Coral Cove – luxury villas with sea views.
Plai Laem / Choeng Mon – premium zone with beachfront residences.
Lamai / Hua Thanon – quiet areas with attractive land prices.
Maenam / Bang Por – ideal for family and long-term investments.

Step 2. Legal Verification (Due Diligence)

Before signing any documents, commission a legal property analysis. This is a crucial stage in the property acquisition process in Koh Samui.

✅ Verify the title deed – preferably Chanote or Nor Sor 3 Gor.
✅ Ensure the plot has access to public roads and utilities.
✅ Verify the developer (for new projects).
✅ Check that the property is free from mortgages or encumbrances.

Step 3. Reservation Agreement

After selecting a property, a reservation agreement is signed with a deposit of 2–5% of the purchase price. This secures the property and reserves it during document preparation.

Step 4. Preparation and Signing of Sales Agreement (SPA)

After completing due diligence, a Sales and Purchase Agreement (SPA) is prepared, which specifies:

purchase price,
payment schedule,
method of ownership transfer (freehold / leasehold),
rights and obligations of both parties.

A well-prepared SPA should be drafted in two languages – English and Thai – and signed in the presence of a lawyer.

Step 5. Payment and FET Document

For foreign buyers, the transaction must be conducted in foreign currency. Funds must be transferred from an overseas account to the developer's or seller's account in Thailand. The bank will issue a Foreign Exchange Transaction Form (FET) – a document confirming the legal transfer of funds. The FET is required for ownership registration at the Land Department.

Step 6. Transaction Registration at Land Office

Property registration takes place at the Land Department Surat Thani (Koh Samui Office). During this stage:

Buyer and seller (or their attorneys) sign documents,
final payment is made,
a new title deed (Chanote) or leasehold entry is issued.

The entire registration process typically takes 1–3 days.

Forms of Property Ownership for Foreigners

Freehold (full ownership) – for condominiums only (up to 49% of building units).
Leasehold (30-year lease) – for villas and houses, with renewal options.
Thai Company Limited – Thai company structure that can own land in full ownership.

Each form is legal and provides full security to the investor, provided the contract is registered at the Land Office.

Step 7. Property Handover

After Land Office registration, formal property transfer occurs. For new projects, handover takes place after construction completion (handover). It's recommended to prepare a technical acceptance protocol – checking workmanship quality, fixtures, and installations.
