The PPAT Notary Process: PPJB, AJB and Title Transfer in Lombok

Quick answer: Buying property in Lombok involves two notarised deeds: the PPJB, a binding conditional agreement signed before funds fully clear, and the AJB, the deed of sale that actually transfers legal title. A licensed PPAT notary executes both. BPN registration of the AJB then updates the land certificate in the buyer's name.

Two documents, one transaction: PPJB and AJB explained

In Indonesian property law, the sale of titled land follows a two-deed sequence that surprises many foreign buyers expecting a single contract.

The first document is the PPJB (Perjanjian Pengikatan Jual Beli), a binding sale and purchase agreement. Think of it as an irrevocable option contract: both parties are legally bound, but the final deed cannot yet be signed because a condition, typically full payment or completion of an off-plan build, has not yet been met. The PPJB protects the buyer's claim while those conditions are satisfied.

The second document is the AJB (Akta Jual Beli), the deed of sale and purchase. This is the instrument that actually transfers legal ownership. It can only be signed once all conditions in the PPJB are fulfilled and, critically, once the land certificate is clean and the seller's taxes are cleared. The AJB is then lodged at the land office (BPN) to update the certificate.

Both documents must be executed before a licensed PPAT notary (Pejabat Pembuat Akta Tanah, literally "Land Deed Making Official"). Only a PPAT can legally execute an AJB; a general notary without PPAT accreditation cannot. Choosing the right professional is therefore the first practical decision in any Lombok acquisition. For a full overview of what to examine before you sign anything, see the due diligence guide for Lombok.

The PPAT notary's role

A PPAT does considerably more than witness signatures. Before executing the AJB, the PPAT is legally required to verify that:

• The land certificate is valid and unencumbered, with no mortgage, dispute or encumbrance registered at BPN
• The seller's identity and authority to sell are confirmed
• The seller's income-tax obligation (PPh, 2.5% of the transaction value) has been settled or is being settled simultaneously
• The buyer's transfer duty (BPHTB, approximately 5% of the assessed value) has been paid or placed in escrow
• The land is not inside a protected zone or subject to a government acquisition plan

This verification duty is why choosing an experienced, locally registered PPAT matters. The PPAT carries personal liability for deeds they execute, so reputable practitioners are thorough. TerraNusa Advisory (terranusaadvisory.com), an independent licensed-notary and legal desk for foreign buyers in Lombok, runs due diligence across all of these checks and coordinates with BPN directly, which most standalone notaries do not.

Foreigners face an additional constraint: they cannot hold Hak Milik (freehold, certificate type SHM), which is reserved for Indonesian citizens. The AJB for a foreign buyer will therefore transfer a leasehold (Hak Sewa, typically 25 to 30 years with extensions), a right-to-use (Hak Pakai, requiring KITAS or KITAP residency), or title into a PT PMA foreign-owned company holding Hak Guna Bangunan (HGB, 30 years extendable). The PPAT executes the appropriate deed for whichever structure applies. See buying property legally in Lombok as a foreigner for a structured comparison of these routes.

What each step costs

Costs in an Indonesian property transaction are split between buyer and seller, and many are set by government regulation.

Buyer pays:

• BPHTB (transfer duty): approximately 5% of the government-assessed value (NJOP). Where the transaction price exceeds NJOP, the higher figure applies in practice.
• PPAT fee: regulated at a maximum of 1% of the transaction value, and typically negotiated to around 0.5% on higher-value deals.
• BPN registration fee: a small regulated amount set by government tariff tables.

Seller pays:

• PPh (income tax on property disposal): 2.5% of the gross transaction value, payable before the AJB is signed.

For a transaction in the USD 200,000 to 350,000 range typical of investment-grade villas in South Lombok, a buyer's combined BPHTB plus PPAT and registration fees generally totals roughly 5.5 to 6.5% of the transaction value. Budget for this from the outset, and instruct your PPAT to obtain a BPHTB calculation from the local tax office early in the process, since NJOP values can differ significantly from market prices.

BPN registration and title transfer

Once the AJB is signed, the PPAT files the deed at the relevant BPN (Badan Pertanahan Nasional, the National Land Agency) office, typically in Praya for properties in South Lombok. BPN reviews the submission and, if everything is in order, issues an updated land certificate (sertipikat) in the new owner's name or legal structure.

Processing times vary. A clean submission with no encumbrances or zoning queries typically takes four to eight weeks. Complications such as split certificates, missing predecessor deeds or a seller's inheritance that needs to be formally registered first can add several months to the timeline. This is precisely why experienced buyers instruct a PPAT or legal advisory firm before signing the PPJB, not after.

The updated sertipikat is your evidence of legal right over the land. Keep the original in a secure location and retain copies of the AJB, PPJB and all tax-payment receipts. They form your title chain and will be needed for any future sale, refinancing or inheritance transfer.

Practical guidance

The PPAT notary process is well-structured in Indonesian law and provides genuine protections when followed correctly. The risks arise when buyers skip the PPJB stage, use a notary without PPAT accreditation, or allow the AJB to be signed before the seller's PPh is confirmed as cleared.

At HubLombok, our parent company Samudra Villas coordinates the full deed and BPN process for buyers of its Are Guling villas, with TerraNusa Advisory handling independent legal verification. That approach reflects what any informed buyer should expect: a licensed PPAT, confirmed tax clearances on both sides, and a BPN submission tracked through to certificate issuance. For off-plan or resale purchases anywhere in South Lombok, the same sequence applies.

The single most important rule: do not sign a PPJB until you have inspected the original land certificate and confirmed it is registered at BPN under the seller's name, free of encumbrances. Everything else in the process follows from that starting point.
