Can my daughters father get unsupervised visitation if he has hepititis C.

You should present your concerns in an affidavit at the court hearing. If your dauther's father is still using drugs, then I doubt that a judge would allow unsupervised visitation. If he can prove that he is clean from drugs and will not place your daughter in unsafe situations, like being around others who use drugs, then he can make a case for unsupervised visits (assuming he was adjudicated or voluntarily acknowledged being the father). I do not know Tennessee law, but I do not think having Hepatitis C necessarily precludes unsupervised visits. I believe that disease is transmitted through contact with the infected person's blood. If your daughter's father is deemed to be responsible for preventing that type of contact, and no other major risk factors are present, then I think a court would allow unsupervised visitation. You would be better prepared for the court hearing if you were represented by a local family law attorney.
