My boyfriend's daughter, 14 years old, has expressed that she wants to live with us. My concern is that if we get the child support that my boyfriend now pays stopped and she comes and lives with us full time, then later on when she gets angry and decides to change her mind again and go back to her mother's then the child support that my boyfriend has to pay will go up and if that happens, we will end up losing our house as we are just making it now. I think that it is in her best interest that she stays with us full time, it's just that there is more at risk than she realizes. We do not have money for an attorney and will have to do this whole thing pro se if we go through with it. The mother and her boyfriend have both told the daughter that she "better not" move in with us because then the mother won't get the child support. The mother does not work and is addicted to pain pills. We dont want to get into a "battle" as we don't have any proof, however, we ourselves know that the cs goes for the pain pills that she buys off the street rather than for the things that the daughter needs. Does anybody have any suggestions?
