"Mom has violated the court's custody order and we are simply restoring the child back into our custody," the judge wrote in the new order. "Nothing more. Nothing less. The court makes no judgment about whether Mom will or will not competently care for the child while in her custody. It only wants the child back where the court placed him."
McCready scored a number-one Billboard country hit in 1996 with "Guys Do It All the Time."
But in recent years, the country crooner has received more media attention for her troubled personal life than her music.
She has been arrested multiple times on drug charges and probation violations and has been hospitalized for overdoses several times, including most recently in 2010, when she was found unconscious at her mother's home after taking a painkiller and muscle relaxant.
The singer's struggle with substance abuse was broadcast last year on the third season of "Celebrity Rehab with Dr. Drew."
McCready also claimed to have carried on a decade-long affair with baseball star Roger Clemens that began was she was 15 and he was 28. Clemens, a former Boston Red Sox pitcher known as "the Rocket," denied that the relationship was sexual in nature.
In August, the singer filed a libel suit against her mother and the National Enquirer's parent company, American Media Inc., over a story that quoted Inge.
"You know what, I don't think I'm ever going to be one of those people that has a normal, quiet existence," McCready told ABC Radio last year. "I've been chosen for some reason to be bigger and larger than life in every way. Negative and positive."
