Many tenants have probably thought: “Rent is so expensive—if I bring in someone else to live with me and share the cost, wouldn’t that save me money?”
It sounds reasonable, but legally it’s not that simple. Tenants may think it’s just “co-living,” while landlords may view it as “subletting.” If handled poorly, tenants may violate the lease, and landlords may struggle with the burden of proof.
What Does the Law Say?
Civil Code Article 443, Paragraph 1:
“The lessee shall not sublease the leased property to another person without the consent of the lessor. However, where the leased property is a house, unless there is an agreement to the contrary, the lessee may sublease a part thereof to another person.”
✨ Plain Explanation: Earlier rules were relatively lenient. If the landlord had not specifically objected, a tenant could sublease part of the house to another person.

Rental Housing Market Development and Regulation Act, Article 9:
“A sublessor shall obtain the written consent of the lessor before subleasing all or part of the residential property leased by him or her.”
✨Plain Explanation: The newer law is stricter. If a tenant wishes to sublease the entire property or part of it, the tenant must first obtain the landlord’s written consent. It is no longer like the earlier rule where subleasing could occur as long as the landlord had not clearly objected.

Rental Housing Market Development and Regulation Act, Article 10, Paragraph 1, Subparagraph 3:
“Where any of the following circumstances occurs during the lease period, the lessor may terminate the lease contract in advance, and the lessee may not request any compensation:
3. The lessee subleases the residential property to another person without the written consent of the lessor.”
✨ Plain Explanation: If a tenant privately subleases the property to another person, the landlord may immediately terminate the lease, and the tenant cannot request any compensation.

Mandatory Provisions to be Included in and Prohibitory Provisions of the Standard Form Rental Housing Contract:
“The lessee shall obtain the consent of the lessor before subleasing, lending, or otherwise allowing another person to use all or part of the leased residential property, or transferring the leasehold right to another person.”
✨ Plain Explanation: The official standard lease contract goes even further. Not only subleasing, but also lending the property or allowing others to use it, all require the landlord’s consent.

What Counts as Subletting?
Legally, the key factor is consideration (payment):
- Family members or partners living together → No payment, no profit → Generally not subletting.
- Classmates or friends splitting rent → If without landlord’s knowledge, may be treated as subletting.
But in practice, proving subletting is difficult:
- If tenants collect only cash, no receipts, no contract → Landlords lack evidence.
- Seeing other people in the house → Could be visitors, family, or partners, not necessarily subtenants.
😱 In other words, even if the law forbids unauthorized subletting, without contracts or payment records, landlords often struggle to prove it.
Lease Types and Signing Methods
- Shared Rooms / Partitioned Studios:
Usually one person per room with separate agreements. Roommates also monitor each other, so disputes are fewer.
- Independent Studios:
Typically signed under one tenant’s name. If that tenant brings in others or subdivides (“illegal room-splitting”), it is easily seen as subletting—unless all occupants are listed in the lease, which rarely happens in practice.
Note: Signing representative ≠ only resident.
- Family leases: e.g., only the father signs, but the whole family of four lives there.
- Corporate leases: a manager signs, but assigned employees actually live in the unit.
The real question is:
- Did the tenant collect payment from others?
- Did the tenant obtain the landlord’s consent?

How to Avoid Disputes?
Whether it’s a landlord worried about loopholes, or a tenant afraid of being misunderstood, the safest solution is clear agreements in advance:
- Resident list: Clearly state all approved occupants in the contract.
- Visitor rules: Overnight stays, visitor hours → Put them in a house rule or annex.
- Communication for changes: If tenants want to add or replace occupants, inform the landlord and get written consent.
Conclusion
If tenants invite others to move in, share rent, or profit without the landlord’s consent, it’s illegal.
But since proving subletting in practice is often difficult, landlords who want peace of mind should set detailed rules in the contract from the start.
This way, landlords have protection, tenants can feel secure, and both sides build trust while avoiding unnecessary conflicts.
