Contracts are negotiated by parties to suit their individual commercial purposes and should be written with a keen eye to avoid ambiguity that could give rise to disputes down the road. Not only must each clause be clearly drafted but all the terms of the contract must be considered in their entirety and be capable of working harmoniously together in order to give meaning and effect to all the terms. Despite this being widely recognized, it is not always accomplished. And, inadvertently, contracts can be silent on some points subsequently triggering disputes.
