My question involves a child custody case from the State of: Michigan. My daughter's mom has been absent from her life for over 2 years. She has been living with me. I have temporary custody of her. Well just lately her mom has been calling and wants to see her. I haven't let her bc she use to be bad in drugs but she claims shes doing good now well she's threatening me with court saying she's going to take me to get hoint custody and visitation. How should i handle this and if we went to court what would happen?
