Value for using the apartment

Allegedly, the law stipulates that all the payments owed by the tenant are ‘in exchange’ and are therefore included in the rent.
This definition is important when it comes to the failure of ancillary payments by the tenant such as current accounts and property taxes.

But in fact, in the leases, it is customary to change this definition, and it is customary to define the consideration only as the monthly rent paid by the tenant to the landlord and without those ancillary payments of bills and taxes.
