Is it permissible for a father to register his deceased wife's land in his name without her heirs, and are the children considered disobedient if they refuse to send him the land documents for fear that he might dispose of it without their knowledge or sell it for a paltry price?

This land has become the property of all the mother's heirs according to their legal shares, and no one has the right to dispose of it without the consent of the others. If the father wishes to register it in his name and some of the siblings do not agree, it is not an act of righteousness to hand him the contract. It is obligatory to treat him with kindness, cheer him up, and avoid harming him. The heirs should agree on a decision that serves the common good and harms no one. If the father needs to marry, his wealthy children should arrange his marriage.
