If there are no survivors, it's best to sit down and talk calmly. If you can't talk, you should consult a lawyer and ask the court for a verdict!
There are laws and regulations about inheritance here!
Article 10 Heritage shall be inherited in the following order:
First order: spouse, children, parents.
The second order: brothers and sisters, grandparents, grandparents.
After the inheritance begins, the successor in the first order inherits, and the successor in the second order does not inherit. If there is no successor in the first order, it is inherited by the successor in the second order.
Children referred to in this Law include children born in wedlock, children born out of wedlock, adopted children and stepchildren with dependency.
Parents referred to in this Law include biological parents, adoptive parents and step parents who have a dependency relationship.
Brothers and sisters referred to in this Law include brothers and sisters of the same parents, half-brothers, adopted brothers and sisters and stepbrothers and sisters with dependent relationship.
Article 13 The shares of heirs in the same order shall generally be equal.
When distributing the inheritance, we should take care of the heirs who have special difficulties and lack the ability to work.
Heirs who have made major support obligations to the decedent or lived together with the decedent can get more points in the distribution of the estate.
If an heir who has the ability and conditions to support fails to perform the obligation of support, he shall not divide or divide the estate.
If the heirs agree through consultation, they may also be unequal.
According to the above provisions, in legal succession, both sons and daughters belong to the first-order heirs, and the share of inheritance of the heirs in the same order should generally be equal.
Unless you have evidence that your sister has the ability to support her parents, but she has not fulfilled her obligation to support her parents, she may get less points or no points.
If you don't appear in court, the court will rule by default.
