My 16 year old dauhter has assaulted me with a 8 in knife the law came and arrested her and is trying her as an adult. Her mother bailed her out. And she is now staying with her mother. The law is trying her as an adult. The child was living with me at the time of the assault. In the state of Maryland will I have to pay child support, on someone who has assaulted me. This just happened a week ago. And has not been to trial yet. But the mother has already threated me with childsupport

Forget about threats and go to the courts and ask them. That is your only solution as we can't guess at what they will do. Under the current laws your responsible for your child until age 18. But the facts of the case may be a game changer. Only a judge can tell you for sure.

Judges have some leeway in cases like this, so we can't predict what a judge will do. Even though the law requires that the non custodial parent pay support, they might consider the circumstances. Of course that will also include WHY she attacked you, something you left out. It's hard to imagine this just came out of the blue.

First and foremost who has the court ordered child support, that order does not change regardless of any crime, or where the child lives, everything required a motion filed in court and a judge rulling.

There is definitely more to the story. She has been in trouble with the law before, last year. She has just got supended from school for fighting the week before. And just got back to school and the next day. I got another call from the school. I was questioning her about the teacher's complaint. She didn't want to hear it and went into another rage

OK, that makes more sense.

If the mother files for support, you may be required to pay. However, if she goes to jail or is institutionalized, a support claim is unlikely.
