Emancipation of Minor

What are New York state guidelines for a minor to become emancipated?

My daughter is 18 years old, as long as she attends school I am obligated to pay child support. She is pregnant and her baby is due next month. Am I still required to pay support for an 18 year old 'child' who will be a single parent? Is it possible to emancipate my 18 year old daughter who will graduate from high school in June?

My daughters 17 year old friend wants to move with in us. Her half-sister has custodianship but has effectively thrown her out and our daughter's friend is now back living with her mother. She feels living with her mother would be a unfit situation but has permission from her mother to move in with us. At 17 years of age is she able to choose where she wants to live over the objections of her custodian? If not does she need to emancipate herself from her half-sister before moving in with us?

What are the laws concerning 'emancipated minors' in the state of Kentucky?

Is there a law that allows an adult (over the age of 18) to remove themselves from a family legally? I thought emancipation was the way to do that but everything I read on emancipation is related to minors. I want to legally remove myself from my family.
