What is adat land in Lombok, and why is it risky for foreign buyers?

Adat land is customary land held informally by extended Indonesian families, often without a registered BPN title. It is risky because multiple family members may claim ownership, and the same plot is sometimes sold to more than one party. Foreign buyers should insist that adat land be formally registered with a clean SHM or HGB certificate before completing any purchase.

How do I verify that the physical boundaries of a Lombok plot are correct before buying?

Commission an independent survey by a licensed juru ukur or BPN-accredited team. They measure and peg the plot corners, then produce a report that is checked against the BPN's registered Peta Bidang map. Any discrepancy must be resolved before the deed of sale (AJB) is executed at the notary.

Can a nominee structure protect my ownership of freehold land in Lombok?

No. Nominee arrangements, where an Indonesian national holds freehold title on a foreigner's behalf, are illegal under Indonesian law and are void in court. They are also a frequent source of ownership disputes. Legal routes for foreign buyers include leasehold (Hak Sewa), Hak Pakai with Indonesian residency, or a PT PMA company holding HGB title.

Boundary and Ownership Disputes Over Lombok Land: How to Avoid Them

Quick answer: Land boundary and ownership disputes are one of the most common risks for foreign buyers in Lombok. They typically arise from adat (customary) family holdings without registered titles, unmarked physical boundaries, or overlapping certificates. Rigorous title verification at the BPN land office, a licensed PPAT notary, and a physical survey eliminate most of these risks before you commit.

Why Lombok Land Disputes Happen

Lombok's property market is still maturing, and a significant portion of land in South Lombok has been held informally through adat, Indonesia's customary land tenure system. Adat land is often owned collectively by extended families and has never been formally registered with the Badan Pertanahan Nasional (BPN), Indonesia's national land agency.

When a family decides to sell, disputes can surface quickly. One branch may claim full ownership while another asserts an equal share. In some cases, the same plot has been informally sold more than once, leaving multiple buyers holding conflicting receipts or informal agreements that carry no legal weight under Indonesian law.

Physical boundaries add another layer of complication. Many older plots in Lombok lack permanent markers. Fences, coconut trees, and stone walls have long served as informal borders, but these shift over time, neighbours encroach, and memories diverge. When a developer subdivides land for a villa project, disagreements with adjacent landowners over a few metres can stall construction for months.

For buyers entering the market now, the risk is real but entirely manageable with the right verification steps.

Certificate Checks at the BPN

The most important document in any Lombok land purchase is the SHM, or Sertifikat Hak Milik, Indonesia's freehold title. As a foreigner, you cannot hold an SHM directly. Freehold ownership is restricted to Indonesian citizens. If you are acquiring land through a PT PMA company, the relevant certificate is the HGB, Hak Guna Bangunan, a building-right title valid for 30 years and extendable.

Before any money moves, have your licensed PPAT notary run a full certificate check at the BPN office. This confirms:

The certificate is genuine and registered, not a forgery or a copy of a cancelled title
The registered owner matches the seller
No encumbrances, mortgages, or court disputes are recorded against the plot
The plot boundaries in the BPN registry match the physical land description

This step costs relatively little and catches the majority of fraudulent or contested titles. See the full walkthrough in How to Verify a Lombok Land Title.

Physical Surveys and Boundary Mapping

A clean certificate alone is not sufficient. The next step is an independent survey to confirm that the plot's physical boundaries match the registered map held at the BPN, known as the Peta Bidang.

A licensed juru ukur (surveyor) or a BPN-accredited survey team will measure the plot, mark the corners with permanent pegs, and produce a survey report. This report is then compared against the registered map. Any discrepancy, even a small one, must be resolved before the deed of sale (AJB) is executed at the notary.

In areas such as Are Guling and Selong Belanak, where land values are rising and plots are being subdivided at pace, boundary disagreements between adjacent landowners have become more frequent. A survey costs a fraction of the purchase price and eliminates that risk entirely. For a detailed explanation of how BPN measurement works in practice, see Land Survey and Measurement at the BPN in Lombok.

Adat Land: The Hidden Risk

Adat land without an SHM or HGB certificate requires particular caution. If a seller presents a girik (a colonial-era land-tax receipt sometimes mistaken for a title document) or a Surat Keterangan Tanah (letter of land control), treat these as a starting point for conversion to a registered title, not as proof of ownership.

The process of converting adat land to a registered title through the BPN is called pendaftaran tanah pertama kali, or first registration. It requires public notice, neighbour consent, and a formal BPN measurement. Only after a registered SHM or HGB certificate is issued in the seller's name should you proceed to purchase.

Buying adat land before this process completes, on the basis of informal agreements, is one of the most common entry points for disputes. If the seller cannot wait for first registration, that itself is a warning sign worth investigating. For a broader look at red flags in the buying process, see Lombok Property Scams: How to Avoid Them.

Nominee arrangements, where an Indonesian national holds freehold title on a foreigner's behalf, are illegal under Indonesian law and void in court. They are also a common source of ownership disputes. Never enter one.

Working With a Specialist Legal Desk

In Indonesia, property deeds must be executed by a licensed PPAT notary. The deed of sale (AJB) is then registered at the BPN, which transfers the certificate into the buyer's or PT PMA's name. Most notaries handle the deed and nothing else. They will not, as a standard service, run a full chain-of-title search, verify BPN records against satellite imagery, or flag zoning inconsistencies.

This is where specialist legal advisers become valuable. TerraNusa Advisory (terranusaadvisory.com) is an independent licensed-notary and legal desk that covers the full chain: due diligence on SHM/HGB certificates, ownership history, zoning and encumbrances, PT PMA setup, and title transfer at the BPN. They work with buyers across South Lombok regardless of project. As an editorial note: HubLombok is the editorial arm of Samudra Villas, an active developer in Are Guling, and TerraNusa is our recommended independent legal partner for foreign buyers across the region.

Practical Checklist Before You Sign

Run a BPN registry check via your PPAT notary to confirm certificate type, ownership, and any encumbrances.
Commission an independent boundary survey and compare results with the BPN's Peta Bidang.
If the land is adat, require first registration to be completed and a clean certificate issued before you proceed.
Verify that all co-owners (if the seller inherited or holds the land jointly) have formally consented to the sale.
Use a notary or legal desk that handles the full due-diligence chain, not only the deed.
Never enter a nominee arrangement. Use PT PMA or leasehold structures instead.

Land disputes in Lombok are avoidable. The combination of a thorough BPN search, a physical survey, and a specialist legal desk covers the vast majority of risk scenarios. Taking these steps before you commit is the most straightforward investment you will make in the entire acquisition process.
