At a hearing Tuesday, Rifqa Bary also is expected to ask a juvenile court judge in Columbus for special immigration status to let her stay in the country.
The teenager is an undocumented immigrant from Sri Lanka who has said she needs the status to continue medical treatment for uterine cancer.
But Bary's parents allege the girl considers herself healed and is refusing chemotherapy after visiting a faith healer last month.
According to CBS Affiliate WBNS, Bary said shed fled Ohio because her Muslim parents threatened to kill her for converting to Christianity.
An investigation by the Florida Department of Law Enforcement found no credible evidence for a threat of an "honor killing" nor any signs of abuse.
Her parents deny she would have been harmed.
