How can I claim my deferred Mahr and my share of the financial compensations resulting from the death of my husband and son in an accident, given that the compensations are disbursed according to a an inheritance decree that does not include the deferred Mahr, and my husband's father does not provide for me and my daughter?

Blood money (Diyya) is wealth like any other inherited wealth; it is divided among the heirs according to the Islamic legal distribution, and the wife has a right to it. The deferred dowry (mu'akhkhar al-sadaq) is a debt that takes precedence over the rights of the heirs, based on the Almighty's saying: "from after any will he may have made or any debt." Therefore, the deferred dowry is taken first from the compensation, and then the remainder is divided among the heirs. It is advisable to be lenient regarding the deferred dowry if it will cause problems with the heirs.
