if you locked her out, if you are the victim of her violence, why are you arguing for visits?
too bad that you signed the service plan. take it and all the court papers and police reports and dcfs reports to a lawyer for real advice. that is the best advice we can give you on the site.
You need to discuss your issues with an attorney who is familiar with DCFS-juvenile cases. If you have not yet signed the service plan , DO NOT until you have discussed this with your lawyer.
Curious - If you locked out your daughter, what exactly are you fighting?
Did you sign this "service plan," often called a "safety plan?" Hopefully you did not, because if you did, irregardless of the facts/circumstances/etc., the only thing that a lawyer can do is defend you if you've been accused of violating said plan.
Before you do anything more, take your paperwork down to a family law attorney.
