My daughter who was 15 run away last 04/07 because she did not like our set of rules and also has placed her other siblings in danger by letting strangers who she just met in the street to have sex with them, she is also smoking pot, shop lift etc behind our back. Now an adult is harboring her and she has been living with them since 5/07.I did not ask for this family to keep her and now they are demanding child support. Do they have the legal right for child support? This is in the state of WA.
