Father named on birth certificate is not my father is my birth certificate legal

Yes, it is. Your father named on your birth certificate IS your legal father. He may not be your biological father, but he is your legal father.

The Osmusman lady told me I have to show adoption paper to get a care provider away from my parent.
Is this true
My birth certificate was filed 6 years after I was born

Could you rephrase your question?

Do you mean an ombudsman? That person is in most instances NOT a legal authority.

Need more info about who you live with now, where you want to live, info of that nature, otherwise it's all guessing.
