Emancipation of Minor

CAN A 15 YEAR LEAVE HOME TO LIVE WITH A FRIEND AND FAMILY?

My nephew lives in nj and was kicked out of his house. by his step-mother and father his father called me to pick him up because he stated that he had to get out of her house. I went to pick him up but what do I do legally because he is in the 11th grade and will turn 18 in three days. Is his father responsible to take care of him finacially because he is still in school?

My 16 year old granddaughter is being treated bad at home, she is not allowed to be with the rest of the family she wants to get emancipation.

What are the responsibilities of the father, who has full legal custody, of a 15 year old son, who lives with his mother. Father lives in N.C. Custody determined by N.C. courts (divorce agreement/decree). child is ungovernable by mother, father wants nothing to do with him. Mother wants him returned to father.

Can a person between the age of 18 and 19 be emancipated from parents, since she lives with the boyfriend in a common law marriage relationship and even have a checking account together, and are witnesses that she lives with this adult man for about year and half, and sustain sexual relationship with this adult man since she was 15 (and the guy was already 22...statutory rape) but since she moved out of the mother house to cohabitate with this man...should be emancipated from parents??? the man that she lives with supports her economically type of husband of house wife deal....point is that she is still pursuing child support from her father even under this circumstances and the mother knows about the whole situation and she supports it and instigate it...the mother matter of fact was the one that went all the way to California to get her the boyfriend and took him to live in her house with this minor under the same roof knowing that they were sustaining sexual relationships and even took her to get an IUD when she was only 16 years of age...now this girl is on her own living like an adult woman since she was pretty much 16 ...now she is almost 19 and is still expecting the CHILD support check....can the father declare her emancipated ans stop paying that money?? does he need to prove to court or somehow someone that this situation is happening or pay until she turns 19 and stop the payments that day???
