My question involves a child custody case from the State of: California.
Background:
My husband took in his daughter just over a year and a half ago a month before she turned 15. She is now 16 1/2 years old. She caused her mother many problems with lying and stealing and finally getting kicked out of the 9th grade. In an argument with her mother who took her cell phone away, she took an excessive amount of Ibuprofen's and ended up in a 72 hour hold and the doctor strongly recommended the teenager come live with us. We accepted the challenge and it has been 10 times worse since she has been with us. From stealing my old cell phone and creating hundreds (over 700 to be exact) of inappropriate photos, videos from her practicing to dance like a stripper to mixing alcohol with candy and finally sneaking her unknown boyfriend into our home while we are at work to have sex among the fact that she can't keep any friends and is always getting into fights at school. Her behavior on social media is completely unacceptable. We have taken her cell phone away but she is becoming more resentful.
Problem:
Social services has now been called three times as she keeps saying that we are neglecting her and physically abusing her. The police have also come and investigated the case and after finding out her entire history have closed the case. The problem is this. I don't want her living in our home anymore. I am a legal secretary and Notary Public and must maintain a crystal clean record. My entire family is afraid she will hurt herself and say I did it. We are oil and water and simply do not get along.
We have begged and I mean begged her mother to take her back but she refuses citing the fact that she has two younger kids from her ex-husband and does not want her to be an influence on them plus she is going through a divorce and fighting custody and believes she will hurt her case.
I feel trapped and a prisoner in my own home. I am to the point where I might just leave. I cannot wait until the day she turns 18. For the record, I did not always feel this way about her. I actually had a decent relationship with her and took her out to many places. It wasn't until after I found out she was stealing my money from my purse, stealing my cell phones, watches, expensive make-up and sneaking boys into our home and the last straw telling social services that I abuse her to "Deflect" what a trouble maker she is.
She has gotten kicked out of school again and we are now forced to register her in a 4th school.
My husband doesn't want her in our home either but we both feel trapped.
QUESTION:
What rights do step-parents have? Can I refuse her to live in our home without my husband being put in a position to pay child support to the state? What options do we have as no one in her family wants to take her in? We said her grandmother on her dad's side would take her in but social services said no because she lives out of state. Any guidance or if I have any rights, please let me know. I am now desperate.
