A retail brand signs a ten-year lease on a flagship store in a busy Jakarta mall. Three years in, the building changes ownership, the new landlord disputes the rent escalation clause, and the tenant discovers the original agreement never addressed what happens when the property is sold mid-term. This kind of dispute is more common than most business owners expect, and it usually traces back to gaps that were visible from day one but never resolved.
Indonesia’s commercial property market has shown steady momentum heading into 2026, with office occupancy in Jakarta’s CBD climbing and retail leasing activity picking up alongside corporate expansion. As more companies sign multi-year leases for offices, warehouses, and retail space, the legal foundation of those agreements matters more than ever. Understanding Commercial Leasing Law is no longer optional groundwork handled quietly by a notary; it is a core part of business risk management.
Why Commercial Leasing Law Carries More Weight in Long-Term Agreements
A short-term lease is forgiving. If something goes wrong, both parties can walk away within months. A long-term tenancy agreement does not offer that flexibility. A poorly drafted clause discovered in year one can follow a business through five, ten, or fifteen years of operation.
Under Indonesian civil law, a lease is governed primarily by the Indonesian Civil Code (KUHPerdata), specifically the chapter on rental agreements spanning Article 1548 through Article 1600. Article 1548 defines a lease as an agreement in which one party binds itself to give the other party enjoyment of an object for a set period, in exchange for an agreed price. That definition sounds simple, but the practical consequences of how a contract translates this principle into specific clauses are where most disputes begin.
For a lease to be legally valid, it must also satisfy the general conditions for a valid agreement set out in Article 1320 of the Civil Code: mutual consent, legal capacity of the parties, a clear object of agreement, and a lawful cause. These conditions sound straightforward on paper, yet many disputes in Indonesian commercial leasing trace back to a failure on one of these points, particularly around who actually has the authority to sign on behalf of a corporate landlord or tenant.
Pitfall One: Vague or Missing Rent Escalation Mechanisms
Commercial leases spanning several years almost always include a rent escalation clause, since fixed pricing across a decade rarely makes financial sense for the landlord. The pitfall is not the existence of escalation, but the absence of a precise formula for calculating it.
Many agreements simply state that rent “may be adjusted periodically” without specifying the percentage cap, the index used, or the notice period required before a new rate takes effect. When a landlord later proposes a steep increase, the tenant has limited contractual ground to push back, because the clause itself was never specific enough to be enforceable in a predictable way.
A well-drafted clause states the exact escalation percentage or formula, the frequency of adjustment, and the written notice period owed to the tenant before any change applies. For tenants operating across multiple cities or building out flagship locations, this single clause often determines whether a five-year lease remains financially sustainable or becomes a renegotiation headache every renewal cycle.
Pitfall Two: Ignoring What Happens When the Property Is Sold
Few tenants think to ask what happens to their lease if the landlord sells the building. Under Article 1576 of the Civil Code, the sale of a leased property does not automatically terminate an existing lease, unless the original agreement specifically states that a sale will end the tenancy. This is a protective rule for tenants, but it only works if the lease is properly documented and dated, since an undocumented or informally dated agreement gives a new owner more room to dispute its validity.
For landlords selling income-generating commercial property, this same rule means due diligence on the buyer side should always include a full review of existing tenancy agreements, since the buyer typically inherits those obligations along with the asset.
Pitfall Three: Unclear Maintenance and Repair Responsibilities
A common source of friction in long-term leases is the boundary between the landlord’s obligation to maintain the structural integrity of a property and the tenant’s responsibility for day-to-day upkeep. The Civil Code places a general obligation on the landlord to keep the property usable for its intended purpose, including major repairs, while the tenant is expected to handle the property with the care of a responsible household head and return it in proper condition at the end of the term.
In practice, this general principle is too broad for a commercial setting involving expensive fit-outs, specialized equipment, or shared building systems. A retail tenant who installs custom refrigeration units, for example, needs a contract that spells out exactly who pays for repairs to that equipment versus repairs to the building’s electrical infrastructure. Leaving this ambiguous invites disputes precisely when a costly repair is needed and neither party wants to absorb the bill.
Pitfall Four: Termination and Renewal Clauses That Favor One Side Too Heavily
Indonesian law distinguishes between leases made in writing and those made orally, and the distinction matters significantly for how a tenancy ends. A written lease with a fixed term expires automatically when that term lapses, without either party needing to give formal notice. An oral or undated lease, by contrast, continues until one party formally notifies the other of its intent to end the arrangement.
This difference catches many businesses off guard, particularly those that have operated under informal renewal arrangements for years without updating the written contract. A tenant who assumes an old agreement is still active, simply because the landlord has not objected, can find that assumption legally indefensible if a dispute arises. Likewise, automatic renewal clauses need a clear opt-out mechanism with a defined notice period; otherwise, both sides risk being locked into terms that no longer reflect current market conditions.
Pitfall Five: Overlooking the Regulatory Side of Commercial Leasing Law
A commercial lease in Indonesia functions as more than a private agreement between two parties. It also serves as supporting documentation for business licensing through the OSS-RBA (Online Single Submission Risk-Based Approach) system, where a valid proof of business location is typically required to obtain operational permits. A lease that lacks proper documentation, or one signed by someone without verified authority to act for the landlord entity, can create downstream problems when a tenant later applies for or renews business licenses tied to that address.
This is particularly relevant for foreign-invested companies (PT PMA) and businesses operating in regulated sectors, where licensing authorities may scrutinize the legal basis of a company’s physical presence more closely than they would for a purely domestic SME.
Building a Lease That Holds Up Over Time
None of these pitfalls require complex legal theory to avoid. What they require is precision: rent formulas stated as numbers and percentages rather than vague language, clear allocation of maintenance costs, explicit treatment of what happens upon a property sale, and termination terms that both parties can live with for the full duration of the agreement.
For a law firm working across corporate and commercial matters, helping a client structure a tenancy agreement is rarely a standalone task. It connects to the client’s broader legal standing, from the legitimacy of its business entity to the way the lease will be treated in a financing transaction or due diligence exercise down the line. Drafting with that bigger picture in mind is what separates a lease document built only for the present from one designed to function smoothly for as long as the business occupies that space.
Companies entering long-term tenancy commitments benefit from involving legal counsel before signing rather than after a dispute surfaces. Our team at WNP Asia regularly advises corporate clients on structuring, reviewing, and renegotiating commercial leasing arrangements, drawing on legal, commercial, and risk-management perspectives to keep agreements balanced for both landlords and tenants. If your business is preparing a new lease or reviewing an existing one, our Practice Areas team is available to assist, and you can also reach us directly via WhatsApp to discuss your specific situation.
