Under the common law of agency, an agent has a duty of fiduciary and loyalty to his/her principal. Thus, as long as the agent uses due diligence and good faith to act in the principal's best interests, the agent has satisfied his/her duty and is not liable for any breach under a general agency contract
The above-described principles can be overruled by express contract language in a written agency agreement.
Also, if the contract has a choice of law provision, then this could be highly relevant, because "common law" agency principles extend to the UK, USA and other common law jurisdictions
. Whereas, in "civil law" jurisdictions, only the express contractual agreement matters, because there is no common law of agency in force.
Thus, if the choice of law for your agreement, is France or Italy, for example, then only the contract matters -- whereas in the UK or USA, the common law of agency controls.
If Israeli law controls -- which is likely if the contract has no choice of law provision, then the common law of agency would be in effect, because Israeli law generally decends from the Torah (of course), but by way of the UK, via the British occupation that predated the current nation of Israel.
Hope this helps.
