Agency is a permissive and revocable contract wherein the principal or the lawyer can rescind the contract whenever they want. Arriving at a stable and non-shaky contract is an issue that can be achieved in the light of the irrevocable agency. However, the principal can perform an action in irrevocable agency that leads to the annulment of the agency contract. For example, the principle may sell the goods of a lawyer whom s/he cannot depose, in which case the aforementioned contract is revoked. To prevent such an action by the principal, the condition “performing of no actions against the subject of agency by the principal” is applied. The present study aimed at investigating the permissibility of this condition and discussed it through taking advantage of a descriptive-analytical method. The study accomplishment signified the idea that the condition “performing of no actions against the agency subject” was amongst the partial right deprivation cases and that it was devoid of any fault hence permissible due to the axiom of the domination of setting such a condition.
