Does the questioner have the right to claim compensation for himself and his wife being deprived from applying for state-allocated lands, as a result of his name being used in allocating a plot of land to his father 25 years ago, which his father now wishes to return in his name?

It is permissible for you to demand financial compensation in exchange for ceding the land to your father, as long as it was purchased from the state in your name, because the right to obtain land is a financial right, which can be exchanged for compensation. Evidence for the permissibility of taking compensation in this matter is derived from khul'.
