Grandparents have died, and uncles have come to split up our family. What should we do?

It's hard to say, it doesn't depend on the law. Don't be afraid if they want to be rough. Those who dare to take the initiative will be indefensible, not to mention unreasonable. Talk to a lawyer. What about the will? What does it say? In short, the lawsuit and the media (if you are determined to settle accounts), don't be afraid, the law is fair, and it is difficult to solve such things privately.
