There is no one answer to this question as each situation is unique. However, there are some general things that can make a mother unfit in Ohio. These include having a serious mental illness, being addicted to drugs or alcohol, abusing children, or being convicted of certain felonies. If a mother is unable to care for her children due to physical or mental health reasons, she may also be considered unfit. Each case will be evaluated on its own merits by the court.
