This statement is inconsistent with the relevant provisions of the law. The estate owner can make a will and give it to whoever he wants.
In the absence of a will, those who do their main duty of maintenance can be given more points.
When distributing the estate, consideration shall be given to heirs who have special difficulties and lack the ability to work.
When distributing the estate, a successor who has made major contributions to the decedent or who lives with the decedent may receive a larger share.
If successors who are able and qualified to support them fail to fulfill their obligations, they shall, at the time of distributing the estate, be given no share or a small share.
Successors may also be unequal if they agree through consultation.
