AJB vs PPJB in Indonesian Property Deals

PPJB (Perjanjian Pengikatan Jual Beli) is the binding preliminary sale-purchase agreement that Indonesian property transactions typically use when not every condition for a full transfer is yet satisfied, permits still being confirmed, payment still being completed in stages, while AJB (Akta Jual Beli) is the final deed of sale, executed before a PPAT notary, that actually transfers rights once every condition is met and the deal is ready to be registered.

Understanding this distinction matters because the two documents give you different levels of protection and represent different stages of the same deal. A buyer who thinks they have completed the purchase after signing a PPJB, when in fact the AJB has not yet been executed, has misunderstood exactly how much legal protection they currently hold.

What PPJB actually is

A PPJB is a binding contract between buyer and seller that commits both parties to complete the sale once specified conditions are met. It typically includes the price, payment schedule, and the conditions, such as permit verification or completion of instalment payments, that must be satisfied before the final AJB can be executed. It is a real, enforceable agreement, but it is not yet the formal transfer of rights.

What AJB actually is

The AJB is the formal deed of sale executed before a PPAT (Pejabat Pembuat Akta Tanah, land deed official), which is the document that actually enables registration of the transfer with the land office. This is the step that completes the legal transfer of rights from seller to buyer (as of 2026, verify current process requirements directly with your notary/PPAT).

Why this distinction matters for buyers

If you are relying on a PPJB alone for an extended period, it is worth understanding exactly what conditions remain outstanding and confirming a realistic timeline for the AJB to be executed. A PPJB that drags on for a long time without progressing to AJB can leave a buyer in a more exposed position than they realise, particularly if a dispute arises.

How this connects to the sale-purchase agreement more broadly

The PPJB is, in effect, the specific form the sale-purchase agreement takes at the preliminary stage of a transaction. Our broader guide on the sale-purchase agreement in Bali covers what terms and conditions should be included regardless of whether the document is titled PPJB or a more general agreement; the principles about conditions precedent, deposit protection and remedies apply either way.

What to check before and after signing a PPJB

1. Confirm exactly which conditions remain outstanding before the AJB can be executed
2. Get a realistic, written timeline for when the AJB is expected
3. Confirm how your deposit or staged payments are protected in the period between PPJB and AJB
4. Ask your notary or PPAT directly what stage the transaction is currently at
5. Do not treat the PPJB as equivalent to completed ownership, it is not

Does every Bali property transaction go through both stages?

Many do, particularly where payment is staged or conditions need time to be satisfied, but not every transaction requires a separate PPJB if conditions can be met immediately and the AJB can be executed directly. Ask your notary or PPAT to explain which structure applies to your specific transaction and why.

Why buyers confuse the two documents

Part of the confusion comes from how both documents get loosely referred to as “the sale-purchase agreement” in everyday conversation, when they actually represent different legal weight and different stages. Some agents and even some translated marketing material use the terms interchangeably, which does buyers no favours. When you are reviewing paperwork, ask directly and explicitly which document you are looking at, PPJB or AJB, and what stage of the process it corresponds to, rather than assuming from the title alone.

This distinction becomes particularly important for leasehold transactions, since the structure of leasehold rights transfer can differ from freehold transfer in how it is documented. A notary experienced in foreign-buyer leasehold transactions should be able to explain exactly how PPJB and AJB, or their leasehold equivalents, apply to your specific deal.

What happens after the AJB is executed

Once the AJB is signed before a PPAT, the next step is registering the transfer with the relevant land office, which formally updates the official records to reflect the change in rights. This registration step is what gives you enforceable protection against third-party claims, so confirm with your notary or PPAT that registration has actually been completed, not just that the AJB has been signed. A signed AJB that has not yet been registered still leaves a gap in your protection that is worth closing as quickly as possible.

Costs associated with PPJB and AJB stages

Notary and PPAT fees, along with applicable transfer taxes, are typically incurred at different points across these stages rather than as a single lump cost at the very end. Ask your notary for a clear breakdown of what is payable at the PPJB stage versus the AJB stage, so you are not caught off guard by costs arriving at a point you had not budgeted for. This is worth confirming in writing alongside the payment schedule set out in your sale-purchase agreement.

What to do next

Understand clearly which stage your transaction is at, PPJB or AJB, and what that means for your actual legal protection at that point. Do not assume a signed PPJB is equivalent to a completed purchase.
