Please restate your question, as it was truncated.

Are you asking whether you have any rights as an heir? It depends on what his will says (if he has one). If he has no will, then in most states you are entitled to a share of his estate. Please post back with more details: was your father married? Do you have siblings? What state did he live in?

I'm in the uk and he has no will and is not married . He has other kids as well ,what do I do next thanks
