I want custody of my niece. She is 16 years old and she no longer wants to live in her house. Her mother goes out and drinks and parties and comes home drunk. Her mother and stepfather are constantly argueing and being aggressive. I think that she will be better off at my house. I have 3 kids and my husband works I am a stay at home mother. She wants to live her but her mother will not allow her to. What can I do?
