Glen Campbell was moved to an assisted living facility last year, after his Alzheimer's disease progressed to a point where his family could no longer care for him on their own. Now, Campbell's two oldest children, Debby Campbell-Cloyd and Travis Campbell, have filed a petition to take control of the country legend's medical and financial decisions away from his wife Kim.

Campbell's children claim that his wife is mishandling his care and finances, and they are asking a judge to protect their father's interests by appointing conservators and a guardian. According to Nashville's Tennessean, a petition filed in court claims that Campbell is "secluded from the rest of the family" and that his children have been "prohibited from participating in his care and/or treatment."

The petition goes on to say that Campbell's wife is not providing him with basic toiletry and clothing needs, nor is she visiting him regularly; it also claims that she is mishandling his finances. According to the petition, several of Campbell's eight children are not on his approved list of visitors. Furthermore, the petition alleges that Campbell's wife is allowing televised interviews at the facility, which is no longer appropriate considering the advanced level of his disease.

Kim Campbell, Glen Campbell's spouse of 32 years, defends her actions, saying that she is acting in his best interest.

"It is crushingly sad to see him afflicted with Alzheimer's, but indulging those feelings does not help him," she says. "I am his wife, and no one wants him home more than me, but I must do what is in his best interest."

Glen Campbell was diagnosed with Alzheimer's in 2011 but went on to tour for two more years, on his Goodbye Tour, until the progression of the illness forced him to stay off the road.

“There’s a lot of sadness,” Kim Campbell admits, “[but] we just continue to try to make the best of every day and keep a sense of humor.”

A documentary of the "Rhinestone Cowboy" singer's extraordinary life and career, Glen Campbell ... I'll Be Me, was released last year. The documentary, which includes the Oscar-nominated and Grammy-winning song “I’m Not Gonna Miss You," will air on CNN in June.
