Quick answer

It depends which rule applies. Under the Civil Code’s default rule, a tenant may sublet unless the lease expressly prohibits it. But for residential units covered by the Rent Control Act, subletting without the owner’s written consent is banned outright and is itself a ground for judicial ejectment, regardless of what the lease says. Because most standard leases also contain their own no-sublease clause, the safe practice in nearly every real case is the same: get written consent first.

The Civil Code Default: Subletting Is Allowed Unless Forbidden

Article 1650 of the Civil Code states the surprising default: “When in the contract of lease of things there is no express prohibition, the lessee may sublet the thing leased, in whole or in part, without prejudice to his responsibility for the performance of the contract toward the lessor.” In other words, absent a clause saying otherwise, the tenant is legally free to sublease, and remains fully responsible to the original landlord for performing the lease regardless. Article 1651 then makes the sub-tenant bound to the original landlord for proper use and preservation of the property, and Article 1652 makes the sub-tenant subsidiarily liable to the landlord for unpaid rent, up to the amount the sub-tenant owes the original tenant under the sublease.

Why Almost Every Lease Prohibits It Anyway

Because Article 1650’s default only applies in the absence of an express prohibition, and landlords generally want control over who occupies their property, the overwhelming majority of residential and commercial lease contracts in the Philippines include a clause explicitly requiring the landlord’s prior written consent before subletting. Once such a clause exists, it controls, and subletting without going through it is a breach of contract exposing the tenant to termination and damages, independent of any statutory rule.

The Rent Control Act Reverses the Default for Covered Units

For residential units falling within RA 9653, the Rent Control Act, the statutory default flips entirely. Section 8 provides: “Assignment of lease or subleasing of the whole or any portion of the residential unit, including the acceptance of boarders or bedspacers, without the written consent of the owner/lessor is prohibited.” Section 9 then lists that same conduct — subletting or assigning the lease without the owner’s written consent — as an independent ground for judicial ejectment. This means that for a rent-control-covered unit, it makes no difference whether the written lease is silent on subletting: the law itself supplies the prohibition, and a tenant cannot rely on Article 1650’s civil-law default to argue that silence means permission.

What Happens If You Sublet Without Consent Anyway

Where the lease itself prohibits subletting, or the unit is covered by the Rent Control Act, subletting without the required consent exposes the original tenant to an unlawful detainer action for breach of a lease condition, in addition to whatever separate liability the arrangement creates toward the unauthorized sub-tenant, who has no independent right against the landlord and can be ejected along with the original tenant.

Subletting Is Not the Same as Assigning the Lease

It helps to keep two related but distinct concepts apart. Subletting means the original tenant remains a party to the original lease and simply lets someone else occupy the unit (or part of it) under a separate arrangement, staying personally responsible to the landlord throughout, as Article 1650 makes clear. An assignment of lease, by contrast, substitutes an entirely new tenant in the original tenant’s place, transferring the lease itself. The Rent Control Act treats both the same way for covered units — Section 8 prohibits “assignment of lease or subleasing” alike without written consent, and groups in the acceptance of boarders or bedspacers as an equivalent form of unauthorized occupancy requiring the same consent. This matters practically: even letting a relative or a boarder stay and contribute to the rent, without formally “subletting” in a legal sense, can trigger the same consent requirement for a rent-control-covered unit.

What a Sub-Tenant Should Know Before Moving In

A prospective sub-tenant is not entirely unprotected even in an arrangement between two private parties. Article 1651 makes the sub-tenant directly bound to the original landlord for proper use and preservation of the property, which cuts both ways — it also means the sub-tenant has an interest in confirming that the head-tenant actually has the right to sublet, since an unauthorized sublease can be terminated by the landlord at any time, taking the sub-tenant’s arrangement down with it regardless of how much the sub-tenant has already paid the head-tenant. Article 1652 further makes the sub-tenant subsidiarily liable to the landlord for any rent the original tenant owes, up to the amount the sub-tenant itself owes under the sublease — so a sub-tenant who has already paid the head-tenant in full is not automatically shielded from a separate demand by the landlord if the head-tenant defaults. Before entering any sublease, it is worth asking to see the original lease contract, or at least a written confirmation from the landlord that subletting has been approved.

Practical Takeaways

Frequently Asked Questions

Can I sublet my apartment without asking my landlord? It depends. Under the Civil Code's default rule, subletting is allowed unless the lease expressly forbids it. But if your unit is covered by the Rent Control Act, subletting without the owner's written consent is prohibited by law regardless of what your lease says, and is a ground for ejectment.

My lease doesn't mention subletting at all — does that mean it's allowed? Under the plain Civil Code default, yes, silence means it is allowed. But this default is overridden for units covered by the Rent Control Act, where written consent is required by law even if the lease is silent.

What happens to my sub-tenant if I sublet without permission? The sub-tenant generally has no independent protection against the landlord in that situation and can be ejected together with the original tenant if the landlord successfully challenges the unauthorized sublease.

Am I still responsible for the lease if I sublet part of my unit? Yes. Article 1650 is explicit that subletting does not relieve the original tenant of responsibility for performing the lease toward the landlord.
