The answer is simple: when they abuse the privilege of raising children. Or in the case of the adoptive parents of a child identified simply as T.H., once the authorities discover that the adopted father was sexually abusing the girl.
It's a horribly sad case.
When T.H. was just three years of age, the courts terminated the parental rights of the girl's mother. It took just one year for another couple to come forward to adopt the girl.

By the time T.H. was 15, she bravely stepped forward and disclosed that the father had been sexually abusing her since she was five or six years of age.
When the court set its process in motion, the adoptive parents backed down and agreed to the termination of parental rights. T.H. filed a petition to reinstate the parental rights of her biological mother.
At first, the state objected to the grill's petition arguing that there was one element of the statute that had not yet been met. The trial court agreed, and the state entered an order denying the application.
There was an appeal to the Oklahoma Supreme Court, which reversed the decision.
T.H. was able to proceed thanks to a fairly new law passed in 2009 by the Oklahoma legislature.
