What will happen if the foreign law gives inheritance rights under law to someone who is not related to the deceased via blood or marriage,or adoption?
It is not needed unless it recognizes inheritance rights given under Israeli law.
What happens if the law of the country where the deceased was domiciled states that if there are no blood relatives the state will inherit? The Israeli court will accept that, providing the foreign law is proved.
What happens if the law of the country where the person is domiciled does not recognize the right of Israel to inherit?
If this is so then Israel will not recognize that state's right to inherit as recognition must be mutual on this.
