If you live in an apartment building or subdivision, ask your landlord about the service fee. Even if your landlord is responsible for paying them, you should see a copy of the service fee contract so you know what work you want the building manager to do and you know who to report problems to. An oral agreement can also be changed. The change will usually also be verbal. In the event of a dispute, proof of the change may be provided if: There are obligations that you and your landlord have that are not specified in the contract, but are required by law and are implied in all leases. These terms and conditions are part of the contract, even if they have not been expressly agreed between you and your landlord.
