TL;DR
Legal rights for tenants in shared housing across Europe. Joint tenancy vs individual leases, liability, deposit splits, eviction rules, and what happens when a flatmate leaves.
Shared housing is the most common entry point for students, young professionals, and expats renting in Europe. But the legal structure behind a flatshare varies significantly by country, and the type of lease you sign determines your rights, your liability, and what happens when things go wrong. This guide covers the key legal distinctions every shared-housing tenant should understand.
Joint Tenancy vs Individual Leases
The single most important distinction in shared housing is whether you are on a joint lease or an individual lease. In a joint tenancy (Gesamtschuldnerschaft in Germany, solidarite in France, solidaridad in Spain), all tenants sign one contract and share collective responsibility. If one flatmate stops paying rent, the others must cover the shortfall. If one causes damage, all are liable. In an individual lease, each tenant has a separate contract for their room. Your liability is limited to your own room and your share of common areas.
Individual leases are far more protective for tenants, but they are less common with private landlords. Agencies that specialise in shared housing are more likely to offer individual room contracts. Check our agency finder to match with agencies handling shared rentals.
Germany (Wohngemeinschaft / WG)
The German WG is the most common form of shared housing in Europe. The most protective structure is a Hauptmieter/Untermieter arrangement, where one main tenant holds the lease and sublets rooms. This gives the main tenant control but also full liability. Alternative: all flatmates as joint tenants (Mitmieter) on one contract, which requires all signatures for any changes. Some agencies and Studentenwerk (student services) offer individual room contracts in purpose-built shared housing.
France (Colocation)
Since the Loi ALUR (2014), colocation is formally defined in French law. Two models exist: bail unique avec clause de solidarite (single contract with joint liability) and baux individuels (individual contracts per room). The solidarity clause means each tenant is liable for the full rent, not just their share, and this liability continues for 6 months after a departing tenant's replacement signs. The 2014 reform introduced the right to individual contracts, but landlords are not required to offer them.
Spain (Piso compartido)
Spanish law does not specifically regulate shared housing. Most pisos compartidos use a single contract with all tenants named, creating joint liability. When one flatmate leaves, the contract technically needs to be renegotiated. Some agencies offer habitacion (room) contracts, which function as individual leases. The LAU applies to the overall lease, but room-only contracts may fall outside its protections, which is a risk tenants should understand.
Netherlands (Kamerverhuur)
Dutch law distinguishes between zelfstandige woonruimte (self-contained) and onzelfstandige woonruimte (non-self-contained, i.e., rooms). Room rentals have different rules: fixed-term contracts can last up to 5 years (vs 2 years for apartments). The points system (WWS) applies differently to rooms. In student housing managed by SSH or DUWO, individual contracts are standard.
United Kingdom (House in Multiple Occupation / HMO)
UK law has specific regulations for HMOs. Properties with 5+ occupants forming 2+ households require an HMO licence from the local authority. This ensures fire safety, room size minimums (6.51 m2 single, 10.22 m2 double), and kitchen/bathroom ratios. Tenants can be on individual ASTs (Assured Shorthold Tenancies) or a joint AST. Individual ASTs are safer for tenants.
Deposit Splits and Returns
In a joint tenancy, the deposit is usually paid as one lump sum. When one flatmate leaves and another replaces them, the outgoing tenant typically receives their share from the incoming tenant, not from the landlord. This informal transfer creates risk: if the deposit is eventually reduced for damage, the deduction may not align with who caused it. Individual leases solve this by keeping deposits separate. For deposit rules by country, use our deposit law comparison table.
What Happens When a Flatmate Leaves
On a joint lease, one tenant leaving changes the dynamics for everyone. In most jurisdictions, removing a name from a joint lease requires landlord consent and a new contract or addendum. The departing tenant remains liable until formally released. On individual leases, one tenant's departure does not affect the others. This is the core advantage of individual contracts.
Utilities and Shared Costs
Whether the contract is joint or individual, shared utilities (electricity, internet, heating) need a clear internal arrangement. The person whose name is on the utility contract is liable for the full bill. Written internal agreements between flatmates (covering cost splits, cleaning schedules, and guest policies) are not legally binding in most countries but serve as evidence in disputes. Check our utility setup guide for registration processes by country.
Finding Shared Housing Through Agencies
Agencies specialising in shared housing handle the legal structure, match compatible tenants, manage deposits separately, and mediate disputes. They charge for this service, but the legal protection of an individual contract managed by a professional is worth the cost for many tenants, especially those renting in a foreign country for the first time.
