Are the heirs obligated to pay the fees for one of the heirs to search for their lost land deed, knowing that the land was expropriated for the Grand Mosque project and that they had previously refused to pay the fees?

The heir who searched for the deed by authorizing some heirs but not others, may charge those who did not authorize him for their share of the cost, because he performed an action for his own benefit and for the benefit of all heirs.
