A dispute between a brother and his sister regarding the dispensation of a shop and a retirement pension

Question:
Shaykh Salih, there is a Saudi man who said to his eldest sister, who is Kuwaiti, "Can you give me a service card, or a work permit, so I can work in it?" The eldest sister agreed. The brother obtained the permit and paid the licensing fees. Then, after a few years, he went to his eldest sister and said, "I will get you a cut, and I will give it to you." Then he lost the air conditioner and the other person sat idle, and there was no retirement pension. Then the younger sister came and took over the shop and worked in it with her own effort, and it started operating, and a retirement pension was established. The question is: when the shop was lost and the younger sister continued the shop's operation, does the agreement between the brother and the eldest sister that she would receive the retirement pension fall away, or does it continue even after the younger sister worked in it? Thank you.

Answer:
By Allah, this is a matter of litigation; they should refer it to the court or reconcile among themselves. However, the eldest sister's action is invalid because she forged the document by giving him the card, which was not his, and he lied in this matter and deceived the system. But in any case, if they reconcile and settle the dispute among themselves, there is no harm. If they disagree, the court is necessary. Yes.
