Re: Complicated situation regarding inheritance law and crypto
How different are the laws in countries on inheritance 
In my country, inheritance is divided equally between the spouse, parents and children. If there is no marriage contract, then the wife will immediately own 50% of the common property after the death of the spouse, and the remaining 50% will be divided between the people from the second sentence.
Oh, this is completely different in my country and in Islamic countries, where the wife receives only 1/8 of the inheritance, and the rest is divided among the children. In my country, inheritance is divided equally between the spouse, parents and children. If there is no marriage contract, then the wife will immediately own 50% of the common property after the death of the spouse, and the remaining 50% will be divided between the people from the second sentence.Obviously, there are significant differences in inheritance laws depending on the country. Therefore, to avoid problems, it is best (as @Lucius mentioned) for the account owner to appoint a legal heir on Binance, to avoid disputes among the heirs over the deceased's account.
Surah An-Nisa (4:11)
It is written here that each parent is entitled to 1/6 of the inheritance, and 1 wife is entitled to 1/8 of the inheritance. So each parent gets more than the wife.
In Summary In Russia, the same first-order heirs are as in Sharia law. But there is one serious disagreement. In Sharia law, the debts of the deceased are paid first, and then the inheritance.
In my country, the heirs will first receive the inheritance after 6 months, and then the creditors will receive their share from the heirs through the court.
Indeed, Surah An-Nisa (4:11) is the primary source of inheritance laws according to Islamic law, but it's not the only source. There are other cases that are derived from the Prophet's hadiths or through ijtihad.
It's great to learn about other cultures and religions, as you can see, since inheritance laws vary greatly from one country to another.
As far as I know, if the Koran says that parents have a share of the inheritance that they are entitled to after the death of their children, then no one can deprive them of this right?
