Pro rata charge allocation on departure

Quick answer

When a co-tenant leaves, charges are split pro rata temporis — each co-tenant pays their share proportional to their actual occupation period. The landlord issues a final statement on the departure date. From that date, the remaining co-tenants assume the departing person’s share.

The charge allocation depends on the type of charges:

  • Individual consumption (electricity, internet in their room): charged entirely to the departing co-tenant until departure
  • Common charges (water, heating, communal electricity, cleaning): split equally among co-tenants present during each period
  • Provisions paid in advance: the final statement calculates the balance owed or to be reimbursed

The co-tenancy agreement (pacte de colocation) should specify how charges are allocated to avoid disputes on departure.

Drawing up the final statement

BalanceReimburse overpayment or collect underpayment

The landlord should provide the final statement within 1 month of the departure date. Both parties should sign the statement to avoid future disputes.

Meter readings matter

Always take meter readings (water, gas, electricity) on the exact departure date. Without readings, allocation becomes approximate and can lead to disputes between co-tenants.

Solidarity clause complications

If the lease contains a solidarity clause (clause de solidarite), the departing co-tenant remains jointly liable for all charges (including rent) until formally released by the landlord.

This means:

  • The departing co-tenant may be pursued for arrears of the remaining co-tenants
  • Only a written release from the landlord can end this solidarity
  • The co-tenancy agreement should address the process for release

Without a solidarity clause, the departing co-tenant is only liable for charges incurred during their occupation period.

Regional specifics

Brussels-Capital Region

The Ordinance of 27 July 2017 introduced a specific legal framework for co-tenancy (colocation). The co-tenancy pact is now a recognised legal document that can specify charge allocation rules.

Wallonia

The Decree of 15 March 2018 also provides a co-tenancy framework. The solidarity clause is limited to the co-tenant’s share plus one departing co-tenant’s share.

Flanders

The Flemish Housing Rental Decree of 9 November 2018 includes specific co-tenancy provisions. The Flemish decree provides a structured replacement mechanism and limits the departing co-tenant’s liability.
