Am I entitled to demand a percentage of the company or a sum of money in exchange for relinquishing it, should I be removed from it, given that I assigned my trade name to them for a symbolic amount?

Summary of the Answer: If the questioner's role in the institution is limited to using their name or identity to complete official paperwork and sponsor foreigners, then they have no right to a share in the company or to claim sums of money; this is because sponsorship is a contract of donation and not an exchange, unless they expended effort or money, in which case they are entitled to their expenses and a wage for their work. If they expended effort in establishing or expanding the company, they are entitled to a wage for their effort. Issues of dispute and contention are decided by the Sharia judge.
