Does informing the deceased's father of his daughter's death, inquiring about his desire to waive his share of the inheritance in favor of the husband and children, and having him witness that, legally absolve the husband and children? And is the presence of the elderly father's sons and daughters taken into consideration in this matter?

The heirs of the deceased woman are: her son, her daughters, her husband, and her father. Her brothers inherit nothing. If the father reaches a stage of senility and becomes incapacitated, his actions are not valid, and his renunciation of his share in the inheritance is not considered. In case of dispute, recourse must be made to the Sharia courts.
