“[to] contribute and pay a sixth proportionate part of the costs expenses outgoings and matters mentioned in the Fourth Schedule hereto such contribution being paid by half yearly instalments on the Twenty-fifth December and Twenty-fourth June.”
“Where a contract lays down a process giving one party the right to trigger a liability of the other party, such as the payment of a sum of money in response to a demand, it is a question of construction of the contract whether the steps in the process are essential to the creation of the liability, or whether the process may unilaterally be varied or departed from without invalidating the demand. Where issues such as those in this appeal arise, it is necessary to identify the minimum requirements laid down by the lease before the obligation to pay the service charge will be created, and then to consider whether the circumstances of the case satisfy those minimum requirements. In considering each of those matters it is not appropriate to adopt a technical or legalistic approach. The service charge provisions of leases are practical arrangements which should be interpreted and applied in a businesslike way. On the other hand, precisely because the payment of service charges is a matter of routine, a businesslike approach to construction is unlikely to permit very much deviation from the relatively simple and readily understandable structure of annual accounting, regular payments on account and final balancing calculations with which residential leaseholders are very familiar. When entering into long residential leases the parties must be taken to intend that the service charge will be operated in accordance with the terms they have agreed. Leaseholders should be able to work out for themselves whether a sum is due to be paid by reading the lease and comparing the process it describes with the information provided in support of the demand by the landlord, without the involvement of lawyers or other advisers.”
“…where the appellant adopts such an ad hoc approach without prior agreement it runs the risk, illustrated by this case, that an individual leaseholder may use the failure to conform with the minimum contractual requirements as a defence to liability.”
