Imagine arriving in Sumba, finding a cliff-top property overlooking the Indian Ocean, and being told that paying a deposit will secure the price while the paperwork is completed later.

Several weeks later, you discover the land is registered only under a Letter C village record, not a BPN land certificate. You also learn it lies within a kabisu (clan) customary territory, and not everyone with authority agreed to the sale. By then, your deposit is gone, and recovering it may be much harder than expected.

These situations are common in Sumba. The island is attracting increasing interest from property investors, but successful transactions depend on thorough legal due diligence before any funds are transferred.

Before committing to a purchase, it is important to understand the ownership structures available to foreign investors, the legal risks unique to Sumba, the due diligence process, and the key legal considerations that can affect your investment. This guide helps you make a more informed decision before buying property in Sumba.

Why Are More Foreign Investors Looking at Sumba?

Sumba has started attracting foreign investors looking beyond Indonesia’s established property markets. The island’s tourism and hospitality industries are growing, and its natural beauty and culture bring steady interest. With well-known resorts opening, Sumba is becoming a strong option for high-end tourism investment.

Sumba is still developing, which sets it apart from Bali. This gives investors opportunities to enter a fast-changing market. As infrastructure improves and the island becomes easier to reach, Sumba is more attractive for long-term investment.

However, investing in Sumba has challenges. A clear understanding of Indonesia’s property laws is essential. Although the rules for foreign ownership are similar to those in Bali and Lombok, Sumba has its own legal and practical issues. These must be recognized and resolved before making any deals.

Why Doesn’t the Bali Playbook Work in Sumba?

If you have researched or purchased property in Bali, you are probably familiar with Indonesia’s property ownership options for foreign investors. Most individuals use Hak Sewa (Leasehold) or, if eligible, Hak Pakai (Right of Use). For commercial investments, the standard approach is to set up a PT PMA

A PT PMA can hold Hak Guna Bangunan (HGB) rights or secure property through leasehold, depending on the investment goals.

The same ownership structures are available in Sumba. The Basic Agrarian Law (UUPA, No. 5 of 1960), which restricts freehold ownership to Indonesian citizens, applies throughout Indonesia.

The legal framework is the same, but the practical realities in Sumba are different. BPN mapping is less comprehensive, the secondary property market is smaller, and adat (customary) land traditions remain strong. In many cases, a kabisu or clan continues to manage land collectively, even when a certificate has been issued.

Standard due diligence, as practiced in Bali, is still necessary in Sumba. However, it is not always enough. You will need to address local realities to ensure a secure transaction.

Durée Définition
UUPA
(Basic Agrarian Law)
Indonesia’s primary land law (Law No. 5 of 1960) governing land rights, ownership, and land use, including restrictions on foreign ownership of freehold land.
Kabisu A traditional kinship or clan system in Sumba, consisting of people who trace their lineage to a common ancestor. Each kabisu typically has its own uma kalada (traditional ancestral house), which serves as the socio-religious center of the clan. In matters relating to customary land (adat land), the consent of the relevant kabisu may play an important role in land transactions.

What Are Your Legal Options as a Foreign Buyer?

Foreign investors have three legal options for acquiring property rights in Sumba. Each structure offers different rights, ownership periods, and permitted uses, so it is important to choose the one that best matches your investment objectives.

StructureWho Can Use ItDuréeIdéal pour
Hak Sewa (Leasehold)Any foreignerNegotiated, typically 25–30 years with extension options to 70–80 yearsLower-commitment personal use; most common individual structure
Hak Pakai (Right of Use)Foreigners with valid KITAS/KITAP residencyUp to 80 years (30 + 20 + 30) under Government Regulation 18/2021One residential property; not suitable for rental business
HGB (droit de construire)PT PMARoughly 30 + 20 + 30 years under the Omnibus Law frameworkVilla development, resorts, and any project generating rental income

If you plan to develop villas or operate a rental business, establishing a PT PMA is generally the appropriate structure. A PT PMA can hold HGB rights or leasehold rights. 

Choosing the right ownership structure before negotiating a purchase will influence your licensing requirements, tax obligations, and long-term investment strategy.

What Has Changed in the Regulations in 2026? 

Two regulatory shifts from the past year now directly affect due diligence in Sumba. 

1. Legacy land titles have lost their status as proof of ownership. 

Under Government Regulation No. 18 of 2021 and ATR/BPN Regulation No. 16 of 2021, Letter C, girik, and other legacy village registrations, which are still common in rural Sumba, ceased to serve as legal proof of ownership after 2 February 2026. 

The land does not automatically revert to the state, and you can still register it. However, these documents now serve only as supporting evidence. To complete registration, you must go through a recognition of rights process, which includes a sworn statement proving at least 20 years of undisputed, good-faith possession. 

If you are considering land offered with a legacy title, have the registration status reviewed before making any payment. ILA Global Consulting can coordinate the legal due diligence process with licensed PPATs and the relevant authorities. 

2. PT PMA paid-up capital requirements were reduced. 

Under BKPM Regulation No. 5 of 2025 and PP No. 28 of 2025, the minimum paid-up capital for a PT PMA has been reduced from IDR 10 billion to IDR 2.5 billion, effective October 2025. 

The IDR 10 billion total investment plan per KBLI code still applies, and paid-up capital cannot be withdrawn from the company account for the first 12 months except for approved operational use. 

If you intend to acquire property through a PT PMA, confirm the latest capital and licensing requirements before incorporating. Our PT PMA Compliance Guide covers the full 2026 obligations once your company is set up. 

These changes do not make investing in Sumba more difficult. They reinforce the importance of verifying both the land certificate and the latest regulatory requirements before signing any agreement or paying a deposit.

Why Does Adat Land Carry More Risk Here Than in Bali?

One of the biggest differences between buying property in Sumba and buying property in Bali is the role of customary land ownership.

Even if a seller presents a valid BPN land certificate, disputes can still arise. In Sumba, land within a kabisu, or clan, is often managed collectively under adat traditions. The consent of the wider clan is just as critical as the name on the certificate.

Disputes between investors and local communities in Sumba are common. Before paying any deposit, ask your notary and legal advisor to check if the land is under customary ownership and ensure all relevant stakeholders have formally approved the sale.

If you cannot confirm these approvals, do not proceed with the purchase. Hold off on any payment until all parties have given clear consent.

Durée Définition
Letter C A village land administration record historically maintained by village authorities to document land possession and land tax obligations.
Girik A historical land document introduced during the Dutch colonial period in Indonesia as evidence of land possession and land tax payment.
Recognition of Rights
(Pengakuan Hak)
A land registration process allowing holders of legacy land documents to obtain formal land rights by meeting statutory requirements, including evidence of long-term possession.

What Should Your Due Diligence Actually Cover?

A clean land certificate is only the starting point of due diligence. Before purchasing property in Sumba, you should verify:

  • BPN land book verification. Confirm the certificate is genuine, identify the registered owner, and check for any encumbrances through a licensed PPAT.
  • Independent land survey. Verify that the physical boundaries match the registered certificate. Some beachfront properties in remote areas may include foreshore land that cannot legally be developed.
  • RTRW and LP2B zoning verification. Confirm that the land is not designated as protected agricultural land under Law No. 41 of 2009, which restricts land conversion regardless of ownership status.
  • Coastal setback requirements. Verify the applicable sempadan pantai directly with the local Dinas PUPR or BPN, rather than relying solely on a broker’s information.
  • Adat and Kabisu stakeholder verification. Ensure any required customary approvals have been formally documented.

Because due diligence in Sumba often involves multiple legal, cadastral, and customary issues, working with an experienced legal consultant can significantly reduce the risk of costly disputes. ILA Global Consulting assists investors throughout the due diligence process before any purchase is completed.

Durée Définition
RTRW
(Regional Spatial Plan)
The regional zoning plan that determines permitted land use and development within a particular area.
LP2B
(Sustainable Food Agricultural Land)
Land designated for long-term agricultural protection under Indonesian law, where conversion to non-agricultural use is generally restricted.
Sempadan Pantai
(Coastal Setback)
A protected coastal buffer zone where construction may be restricted or prohibited to safeguard coastal ecosystems and public interests.

What Will Buying Property in Sumba Cost?

In addition to the purchase price, you should also budget for the taxes and transaction costs associated with acquiring property in Indonesia.

Tax / FeeWho PaysTaux
BPHTB (acquisition duty)Buyer – applies to registered land rights (Hak Pakai, HGB)5% of transaction value above the regional exemption threshold
PPh Final (disposal tax)Vendeur2.5% of gross transaction value
PPAT/notary feeBuyer (customarily)Regulated, scales with transaction value
PBB (annual land tax)Owner, annuallyCapped at 0.5% of assessed taxable value (NJKP); actual rate depends on local regulation 

Hak Sewa is a contractual right rather than a registered land title. As a result, leasehold buyers typically do not pay BPHTB. For individual investors, Hak Sewa can be a practical and more affordable choice. The lessor is still responsible for paying income tax on any lease payments they receive.

Indonesia does not charge a separate capital gains tax on property sales. Instead, sellers who transfer a registered land right (Hak Milik, HGB, or Hak Pakai) pay a 2.5% Final Income Tax (PPh Final). This tax is calculated on the gross transaction value, not on the profit from the sale.

If you are purchasing property through a PT PMA, you should also budget for company incorporation, licensing, and ongoing compliance costs. 

What Happens After the Deed Is Signed?

Finalizing the purchase is just the beginning. Many coastal areas in Sumba have limited infrastructure. You should plan for additional investment in essentials such as solar power, boreholes, water storage, and access roads, depending on your property’s location.

Construction in Sumba typically takes longer than in developed markets. The secondary property market is limited, so selling or transferring a leasehold often requires patience and cooperation from the original landowner.

For these reasons, property investment in Sumba is generally better suited to a long-term investment strategy.

Successful investment in Sumba requires more than choosing the right property. You also need to select the correct ownership structure, verify the land certificate, and complete thorough legal due diligence before signing any agreement.

If you are considering purchasing property in Sumba, ILA Global Consulting can help you assess the most suitable ownership structure, conduct legal due diligence, and guide you through the acquisition process from start to finish.

Questions fréquemment posées

Can a foreigner buy land in Sumba?

Yes. While foreigners cannot personally hold Hak Milik (Freehold Title), they may legally acquire land through a PT PMA under Hak Guna Bangunan (HGB), or use other structures such as Hak Pakai or Hak Sewa depending on their objectives. 

What’s the biggest due diligence risk in Sumba that doesn’t exist in Bali?

One of the biggest risks is purchasing land that has not yet been fully registered with BPN. Many properties in Sumba are still held under legacy village records or incomplete documentation. Therefore, thorough legal due diligence is essential before conducting any transaction. 

Are Girik or Letter C certificates still safe to buy in 2026?

Not as a sole basis for ownership. Since 2 February 2026, Letter C and girik registrations no longer count as legal proof of ownership. They can still support a “recognition of rights” registration at the local land office, but this requires additional documentation, including a sworn statement of at least 20 years of undisputed possession, and takes longer than a standard transfer. 

How long does it take to purchase property in Sumba?

A property purchase typically takes three to six months, although the timeline may be longer if you need to establish a PT PMA or additional due diligence is required for customary land ownership.

Do I need a PT PMA if I only want a private holiday villa?

Not necessarily. A private holiday home that is not used for commercial rental purposes can generally be acquired through Hak Pakai (subject to residency requirements) or Hak Sewa (Leasehold). A PT PMA is generally appropriate if you intend to develop property or generate rental income.
