Transfer of sponsorship of mother and sisters to son

Hi everyone, my father passed away 5 days ago. Since then I have been trying to get the sponsorship of my mother and unmarried sisters transferred to my name. I have completed the initial formalities of court but jawazat refused to transfer as my profession is not doctor or engineer. My profession currently is sales executive. Can anyone please advise if there is any possibility to get them under my sponsorship.

I am sorry for your loss. On the side I wanted to know about the process and requirements for the transfer of the parents under your sponsorship if you don't mind?
