A Daughter Inheriting Her Father Where There Are Brothers: Does a will written in secular courts uphold? Can A Daughter Demand payment to sign over the assets to her brothers?

Is Kofin Al Midas S'doim a Rabbanic decree to torah Decree? What happens if someone doesn't write a will does a daughter inherit like dina D'malchusa or does a daughter not inherit like Torah Law? Does a will written in secular courts enough for a daughter to have the right to inherit her father? Can a daughter demand payment to sign over her inheritance to her brother or does Kofin Al Midas Sdom apply here? In Eretz Yisroel where zoning requires when making an extension to get his neighbors to sign they are okay with his plans. Must one accommodate their neighbor? Interesting question where a brother was mevater and gave his sisters his inheritance does he have to pay maser on her portion?
