A child protection case involves the parent(s) being accused of child abuse or neglect.
A delinquency case typically involves a juvenile (usually a teenager) being accused of a crime.
These cases are also called abuse and neglect cases.
If you're accused of child abuse or neglect you need an experienced attorney. You do not want to represent yourself!
Legally these cases are civil, not criminal. But the reality is that you will feel like a criminal.
You're doing yourself a big favor by hiring an experienced attorney to get you through this process.
I have that experience. More info here: CPS Cases
Juvenile delinquency cases and child protection cases. These types of cases are very different.
