Here are the grounds for termination of parental rights in NC Statute 7B-1111:
Circumstances That Are Grounds for Termination
Abandonment or Extreme Parental Disinterest
Abuse/Neglect
Mental Illness or Deficiency
Alcohol or Drug Induced Incapacity
Failure of Reasonable Efforts
Abuse/Neglect or Loss of Rights of Another Child
Failure to Provide Support
Failure to Establish Paternity
Child Judged in Need of Services/Dependent
Child’s Best Interest
Child in care 15 of 22 months (or less)
Felony assault of child or sibling
Murder/Manslaughter of sibling child
Circumstances That Are Not Grounds for Termination
Felony Conviction/Incarceration
Sexual Abuse
Failure to Maintain Contact
I don’t know about how the lawyer would go back if it wasn’t presented at the time other than it could be appealed due to knowledge not being present to the court. But according to the above reasons, it may not be enough to have his rights terminated. Sadly enough.
