Shared housing in Belgium: individual vs joint lease, guarantees and insurance
In-depth guide to shared housing in Belgium. Individual vs joint lease, Flemish specificities, rental guarantee, insurance and replacing a co-tenant.
Individual lease vs joint lease: a determining choice
The choice between an individual lease and a joint lease is the most important decision in shared housing. It determines your level of financial responsibility, your rights in the event of departure and your legal relationship with the landlord.
In Belgium, both options coexist and each region has developed its own rules. Understanding the implications before signing is essential to avoid very costly surprises.
Before any shared housing viewing, ask the question: “Is this an individual lease per room or a joint lease for the whole property?” The answer radically changes your rights and risks.
Detailed comparison
| Criterion | Individual lease | Joint lease |
|---|---|---|
| Signatory | One co-tenant | All co-tenants |
| Subject | Room + common areas | Entire property |
| Rent liability | Their share only | Entirety (if joint liability) |
| Departure | Independent | Complex (replacement) |
| Guarantee | Individual | Joint or individual |
| Landlord management | More contracts | Single contract |
| Total rent | Often higher | Often lower |
| Co-tenant risk | Low | High (joint liability) |
The joint lease with joint liability clause
The joint liability clause is the legal mechanism by which each co-tenant can be held liable to pay the entirety of the rent if the others default. It is a guarantee for the landlord, but a considerable risk for co-tenants.
Three co-tenants sign a lease at 1,500 EUR/month with joint liability. One leaves without paying. The remaining two must pay 1,500 EUR to the landlord, then try to recover 500 EUR from the departed co-tenant. In practice, this sum is often lost.
Shared housing in Flanders: the Woninghuurdecreet
A specific framework since 2019
Flanders is the region that has most formalised the shared housing framework with the Woninghuurdecreet. The specific rules are:
Duration and notice:
- The shared housing lease is concluded for an indefinite or fixed term
- The departing co-tenant gives 3 months’ notice (compared to 2 months in Brussels)
- No departure compensation for the co-tenant who has respected their notice period
Rental guarantee:
- Maximum 3 months’ rent (compared to 2 months in Brussels and Wallonia)
- Paid into an individual blocked account
Replacement:
- The departing co-tenant must propose a replacement to the landlord
- The landlord can only refuse for a serious reason (insolvency, unsuitable household composition)
- If no replacement is found, the notice period still runs and the co-tenant is released at its end
Comparison between the 3 regions
| Element | Brussels | Wallonia | Flanders |
|---|---|---|---|
| Specific framework | Since 2018 | Since 2018 | Since 2019 |
| Co-tenant’s notice | 2 months | 2 months | 3 months |
| Max guarantee | 2 months | 2 months | 3 months |
| Presumed joint liability | No | No | No |
| Mandatory replacement | Yes | Depends on lease | Yes |

The rental guarantee in shared housing
With a joint lease
Two options:
- Joint guarantee: a single blocked account in all co-tenants’ names. Simpler but problematic when a co-tenant leaves (the guarantee is not partially released).
- Individual guarantees: each co-tenant pays their share into a separate blocked account. More flexible in the event of co-tenant changes.
With individual leases
Each co-tenant pays their guarantee individually. Release occurs at the end of each individual lease, independently of the other co-tenants.
The problem of a co-tenant’s departure
With a joint lease and joint guarantee, the departing co-tenant cannot recover their share of the guarantee while the lease is ongoing. The solution: provide in the co-tenancy agreement that the replacing co-tenant reimburses the departing one’s share.
Always favour individual guarantees, even with a joint lease. Ask the landlord to open a blocked account per co-tenant. This greatly simplifies things in the event of turnover.
To understand the rules of the rental guarantee, consult our page on the lease agreement.
Insurance in shared housing
Specific risks
Shared housing presents particular insurance risks:
- Multiple occupants increase the risk of a claim (fire, water damage)
- Each co-tenant’s personal belongings must be covered individually
- Liability in the event of a claim can be joint or individual depending on the lease
Insurance options
| Option | Joint lease | Individual lease |
|---|---|---|
| Single policy (all) | Yes, in all names | Not applicable |
| Individual policy | Each subscribes | Yes, mandatory |
| Shared housing extension | Depends on insurer | Depends on insurer |
Necessary coverages
- Tenant liability: damage caused to the rented property (fire, water damage)
- Neighbour recourse: damage caused to adjacent properties
- Contents (personal belongings): theft, fire, water damage to your possessions
- Civil liability: damage caused to third parties in the property
Cost
Allow 80 to 150 EUR/year per co-tenant. It is a modest investment given the risks covered. Compare offers from several insurers and check that the shared housing option is explicitly provided for.
Replacing a co-tenant
The legal procedure by region
In Brussels:
- The departing co-tenant proposes one or more replacements to the landlord
- The landlord has 1 month to accept or refuse (serious grounds required)
- If the landlord refuses without grounds, the co-tenant is released at the end of the notice period
- The replacement signs an amendment to the lease
In Wallonia:
- The rules are similar but less detailed than Brussels
- The lease may provide specific replacement conditions
- The landlord’s consent remains necessary
In Flanders:
- The departing co-tenant proposes a replacement
- The landlord can only refuse for serious grounds
- If no replacement is found, the co-tenant is still released at the end of the 3-month notice period
The replacement checklist
- Notify the departure by registered post (to the landlord and co-tenants)
- Find a compatible replacement (solvency, compatibility with the others)
- Propose the replacement to the landlord with their application file
- Organise an intermediate property inventory (between the departing and incoming tenant)
- Sign the lease amendment (or a new individual lease)
- Transfer the rental guarantee share
In shared housing, turnover is inevitable. Provide for the replacement procedure in the co-tenancy agreement: notice between co-tenants, contribution to the search, intermediate property inventory. The clearer things are upfront, the fewer conflicts at the time of departure.

Frequently asked questions
-
The individual lease is a contract signed between the landlord and a single co-tenant, covering a room with the right to use common areas. The co-tenant is only responsible for their own rent. The joint lease is signed by all co-tenants together: they share responsibility for the total rent, especially if a joint liability clause is included.
-
Since 2019, the Flemish Woninghuurdecreet officially recognises shared housing (medehuur). The Flemish shared housing lease provides for 3 months' notice for the departing co-tenant, a maximum guarantee of 3 months' rent, and the obligation for the departing co-tenant to propose a replacement. Joint liability must be explicitly provided for in the lease.
-
With a joint lease with joint liability, the other co-tenants must cover the shortfall vis-a-vis the landlord. They can then take action against the defaulting co-tenant. With an individual lease, only the defaulting co-tenant is concerned: the landlord cannot demand payment from the others. In all cases, a written formal notice is the first step.
-
It depends on the policy. With a joint lease, a single policy can cover all co-tenants if taken out in all their names. With individual leases, each co-tenant must take out their own insurance. Check that the policy covers tenant liability, personal belongings and neighbour recourse. The cost is generally 80 to 150 EUR/year per co-tenant.
