How can you put an out of control teen into foster care?

You would have to call your local department of social services and ask for the child welfare department. Tell them about your situation and let them know that you need help with your teen. A case manager or social worker will likely talk to you about your situation and discuss different options. They may try to work with the teen in the home first. In my opinion this is the best option unless the teen is violent towards you or you're at risk of abusing the teen.

Foster care is not all that great for teens. It's hit or miss. They may go into a great foster home or a really bad one. In my experience and the experience of other social workers, many teens do not get better in foster care - they get worse.

Even if you happen to get them in a foster home, you need to work to improve your parenting skills so that they can come home and you can get control of your teen at home. Foster care should be used as a last resort and should be temporary.

Try other strategies first such as reading books on parenting troubled teenagers, going to parenting classes and parenting support groups. Try family therapy, even if you can't get your teen to go, you should still go to therapy sessions.

You will not get control of your teen until YOU change. You have to change first before you can expect your teen to change.
