According to my country's inheritance law, the first-order legal inheritance is: spouse, children, parents, and the second-order legal heirs are: brothers and sisters, stepparents, and grandparents. After the legal inheritance begins, the first-order heirs inherit. Heirs in the second order do not inherit. If there is no heir in the first order, the heirs in the second order will inherit. Several people who have an inheritance relationship with each other die in the same event. If the time of death cannot be determined, it is presumed that there is no heir to die first. If the deceased have their own heirs, if several deceased persons have different identities, it is presumed that the elders died first; if several deceased persons are of the same generation, they are presumed to die at the same time, and no inheritance will occur to each other, and their respective heirs will inherit separately.
